Focus of the Week– Rangelands, water, carbon and global warming
By Bonnie Dickson and Laurel Rogers, USGS California Water Science Center March 25 2015 Posted by www.climate.calcommons.org
“Results from this study reinforce the role of open rangelands in capturing water and reducing runoff. Maintaining rangelands can help mitigate the effects of climate change and drought.”
Grassland habitats on rangelands in California’s Central Valley and surrounding foothills could decline by as much as 37 percent by 2100 due to changes in land use and climate, according to “Integrated climate and land use change scenarios for California rangeland ecosystem services: wildlife habitat, soil carbon, and water supply,” by USGS researchers funded by the California Landscape Conservation Cooperative. In addition to habitat loss, the study shows that increased development of rangelands for urban use exacerbates the ongoing issues surrounding rainwater runoff. When this issue is combined with periods of drought, the area will suffer from reduced opportunities for groundwater recharge, especially on deep soils. “Results from this study reinforce the role of open rangelands in capturing water and reducing runoff,” said Dr. Kristin Byrd, the study’s lead author and a physical scientist with the USGS. “Maintaining rangelands can help mitigate the effects of climate change and drought.”
Rangelands are the largest land cover by area in California, covering more than one-half of the state. Though more commonly known for livestock grazing, rangelands provide multiple ecosystem services such as habitats for fish and wildlife and carbon sequestration. Rangelands also provide opportunities for surface and subsurface water collection and storage. To better understand the potential detrimental effects of climate change and land use change on rangeland ecosystem services, scientists worked with ranchers and land managers to develop six scenarios for the Central Valley and surrounding foothills. The model scenarios were consistent with three Intergovernmental Panel on Climate Change emission scenarios. To date, there are few studies that examine the combined effects of climate and land use change on rangelands. “Results show the importance of accounting for recharge areas, which provide opportunities for water storage in dry years, in climate-smart land use planning efforts. Given projections for agriculture, more modeling is needed on feedbacks between agricultural expansion on rangelands and water supply,” said Lorraine Flint, co-author and research hydrologist with the USGS.

In addition to biodiversity conservation, California rangelands generate multiple ecosystem services including livestock production, drinking and irrigation water, and carbon sequestration. California rangeland ecosystems have experienced substantial conversion to residential land use and more intensive agriculture.
To understand the potential impacts to rangeland ecosystem services, we developed six spatially explicit (250 m) climate/land use change scenarios for the Central Valley of California and surrounding foothills consistent with three Intergovernmental Panel on Climate Change emission scenario narratives. We quantified baseline and projected change in wildlife habitat, soil organic carbon (SOC), and water supply (recharge and runoff). For six case study watersheds we quantified the interactions of future development and changing climate on recharge, runoff and streamflow, and precipitation thresholds where dominant watershed hydrological processes shift through analysis of covariance.
The scenarios show that across the region, habitat loss is expected to occur predominantly in grasslands, primarily due to future development (up to a 37 % decline by 2100), however habitat loss in priority conservation errors will likely be due to cropland and hay/pasture expansion (up to 40 % by 2100). Grasslands in the region contain approximately 100 teragrams SOC in the top 20 cm, and up to 39 % of this SOC is subject to conversion by 2100. In dryer periods recharge processes typically dominate runoff. Future development lowers the precipitation value at which recharge processes dominate runoff, and combined with periods of drought, reduces the opportunity for recharge, especially on deep soils.
Results support the need for climate-smart land use planning that takes recharge areas into account, which will provide opportunities for water storage in dry years. Given projections for agriculture, more modeling is needed on feedbacks between agricultural expansion on rangelands and water supply.
Food fight: Should the government link beef to global warming?
By Kurtis Alexander March 21, 2015 Updated: March 21, 2015 9:06pm
When a panel of nutrition experts told the federal government last month that consuming beef was not only bad for humans but destructive to the environment, many thought the idea of eating sustainably had finally gone mainstream.
No longer would it be just the Bay Area and the likes of Portland and Vermont that weighed whether their food choices harmed the planet. Leaders in Washington would step up and promote farms that don’t waste water and spew greenhouse gases, and the wisdom of an Earth-friendly diet would resonate across a burger-loving nation. Not so fast. The panel’s advice for how the government should update its influential dietary guidelines has stirred a backlash, led by the meat industry and some members of Congress. They say panel members overstepped their mandate to counsel on nutrition. One online petition to reject the group’s environmental concerns, joined by plenty of people who simply want to enjoy their protein without hassle, demanded, “Hands off My Hot Dog.”
Supporters of the panel now worry that policymakers in charge of rewriting the food guidelines this year may dismiss any suggestion that people eat with the planet in mind, denying sustainability a place in the national dialogue. “I don’t know how the politics of this will play out,” said Marion Nestle, a New York University nutrition professor who recently taught a class at UC Berkeley, has written extensively on food policy and supports the advisory group’s findings. “But I will be very surprised if that (part on sustainability) comes out in the guidelines as strong as the committee suggested.”
Every five years, the U.S. Department of Agriculture and the Department of Health and Human Services are charged with updating the nation’s dietary recommendations. The work helps craft school and military menus and shapes the consumer-oriented food pyramid, now redesigned as a plate. And every five years, a food fight ensues because huge amounts of money are at stake, including the nation’s $10 billion-plus school lunch program. This is the first year, however, that the government’s advisory panel has significantly weighed environmental issues, drawing in a debate with a flavor that’s historically reserved for oil pipelines and auto emissions. While people are putting more and more thought into their food decisions, such as reducing pesticides and mercury in diets, those choices are often driven by personal health. Taking into account the well-being of a warming planet is not as common. And it’s certainly more abstract.
In the advisory panel’s 571-page report, the group says no food needs to be eliminated from the American diet, but it singles out “animal-based food,” particularly beef, as using a disproportionate share of land, water and energy and producing harmful greenhouse gases. Critics counter that the panel not only had no business discussing the environment, but also wasn’t qualified to do so. And they certainly didn’t like the panel’s bottom line: that eating less beef is an Earth-friendly move.
“We believe that sustainability is an important topic. It’s certainly one that cattle farmers and ranchers welcome,” said Shalene McNeill, director of human nutrition research for the National Cattlemen’s Beef Association. “But the panel members don’t have the expertise to take on the topic of sustainability. … Nutrition experts have typically not had that training.”
Sustainability is indeed a complex subject. No single measure exists for evaluating it, much less a universal seal of certification. Some people might favor a foreign food produced organically over a local one produced with pesticides, citing toxic agricultural runoff, while others might prefer the local food because it means less carbon dioxide emitted during transit. This month, heavyweights in the meat industry, including McDonald’s and Tyson Foods, announced the formation of the U.S. Roundtable for Sustainable Beef. The goal is to examine the concept of sustainability and see how beef producers might get on board. McDonald’s has said it wants to source sustainable beef by next year. Already, though, a subset of the industry claims to be operating sustainably. Efforts to raise cattle in harmony with the environment were pioneered decades ago in Northern California, where grass-fed herds have long roamed free of feedlots and growth hormones, and their meat has been welcomed at many Bay Area restaurants.
Grazing over feeding
“Not all ranching and farming entities are the same,” said sixth-generation rancher Loretta Swickard, whose family’s Five Dot Ranch doesn’t use antibiotics or hormones and pledges to responsibly manage its rangeland in nine Northern California counties. “We have a passion for what we’re doing, and we wouldn’t do it if we didn’t think we were benefiting the environment and the consumer.” Places like Five Dot Ranch have been praised for promoting grazing over feeding with mostly grains, which typically require more water and energy to produce. They’re also credited with treating animals more humanely and even producing healthier, tastier food. Since they embrace the spirit of sustainability that the federal panel is pushing, many of these producers believe they will get along fine no matter what the government says about beef.
But the question of whether their cattle are that much better for the planet is hardly settled. Cows inevitably generate methane, a potent gas that contributes to global warming, no matter how they’re raised. About 2.2 percent of the country’s heat-trapping emissions are owed to beef production, the equivalent of roughly 33 coal-fired power plants, according to the Union of Concerned Scientists. The recent dietary report concludes simply that a plant-based diet has “less environmental impact.”
Many in Congress are either not convinced or not interested in the advice, and are defending the beef industry. Several lawmakers, mostly Republicans, have criticized the panel’s report, saying “lean meat” in moderation should be encouraged in the American diet and that sustainability was beyond the scope of the advisory body. A letter this month from 30 senators to the USDA and the Department of Health and Human Services relayed these concerns. It also requested more time for stakeholders to weigh in before policymakers draft the guidelines, expected late this year. The public comment period has since been extended through May 8, with a hearing scheduled for Tuesday in Bethesda, Md.
As the debate rages, neither USDA Secretary Tom Vilsack nor Health and Human Services Secretary Sylvia Mathews Burwell has said whether sustainability will play a role in the dietary recommendations. New York University’s Nestle, who hosts the blog Food Politics, said recent efforts by Vilsack to calm worried beef producers suggest environmental concerns won’t be in the final guidelines. While dozens of health and environmental organizations have lined up to support the inclusion of sustainability, including the Johns Hopkins Center for a Livable Future and Friends of the Earth, they’re no match for big business, Nestle said. “They don’t have anywhere near the credibility (with policymakers) that the beef industry does,” she said. “The industry is talking dollars and jobs. And it’s un-American not to like beef.”
The National Cattlemen’s Beef Association and the meat processing sector cumulatively spent nearly $5 million on lobbying last year, according to the political money tracking website OpenSecrets.org.
Despite the push to leave sustainability out of the discussion, panel member Miriam Nelson, a nutrition professor at Tufts University outside Boston, said in an interview that the evidence linking food choices to environmental welfare has become too strong to ignore. “The science in the last decade is robust. It’s strong,” she said, noting that other countries have begun considering the environmental toll of food in dietary policies. “It seemed like it was the right time” for the U.S.
Conveniently, Nelson pointed out, foods that are less sustainable are also generally less healthful. The advisory panel, for example, considers red meat a health risk, and suggests cutting back on it. The environment becomes just one more reason to do so. Already the private sector has begun to recognize an increasing demand for environmentally friendly products, said Dave Rochlin, who runs an innovation program at the Haas School of Business at UC Berkeley and works with companies to reduce their impact on the climate.
Major corporations like General Mills and Walmart are starting to promote sustainability and have been buying competitors known for environmental commitments, such as Burt’s Bees and Ben and Jerry’s.
“There have always been pockets of consumer demand for sustainable products,” Rochlin said. “I don’t want to say it was a red state-blue state thing. But now, these products are becoming mainstream.” At Alfred’s Steakhouse in San Francisco, a landmark for beef lovers since 1928, the dimly lit dining room still boasts its old red leather booths, crystal chandeliers, jazz music heavy on the horns, and a meat locker proudly displaying its aged cuts. But the menu has a new item: grass-fed filet mignon from a small, local producer, among other Earth-conscious dishes. “It hasn’t always been like this,” said owner Marco Petri, whose family bought the restaurant more than 40 years ago. “This city has a low tolerance for big producers (now). … And people want to know where their food came from.”Down the street, outside Super Duper Burgers, which advertises all-natural beef and organic shakes, city resident Sam Smith, 28, said he watches what he eats, mainly for health reasons, but he’s also been factoring in the environment. “It’s become more important to me not just to cut back on how much meat I eat,” he said, “but to make sure I eat the right kind of meat.”

Large-scale climate patterns that affect the Pacific Ocean indicate that waters off the West Coast have shifted toward warmer, less productive conditions that may affect marine species from seabirds to salmon, according to the 2015 State of the California Current Report delivered to the Pacific Fishery Management Council. The report by NOAA Fisheries’ Northwest Fisheries Science Center and Southwest Fisheries Science Center assesses productivity in the California Current from Washington south to California. The report examines environmental, biological and socio-economic indicators including commercial fisheries and community health. “We are seeing unprecedented changes in the environment,” Toby Garfield, Director of the Environmental Research Division at the SWFSC, told the Council when presenting the report, citing unusually high coastal water and air temperatures over the last year. Climate and ecological indicators are “pointing toward lower primary productivity” off California, Oregon and Washington, he said. That could translate into less food for salmon and other marine species, added Chris Harvey of the Northwest Fisheries Science Center. High mortality of sea lion pups in Southern California and seabirds on the Oregon and Washington coasts in recent months may be early signs of the shift. Among the highlights of the new State of the California Current Report:
- Record-high sea surface temperatures combined with shifts in the Pacific Decadal Oscillation, North Pacific Gyre Oscillation and weaker upwelling of deep, cold waters indicate declining productivity in the California Current.
- After several productive years the biomass of tiny energy-rich organisms called copepods, which support the base of the West Coast food chain and provide important food for salmon, has declined significantly.
- California sea lion pups and seabirds called Cassin’s auklets found dying and emaciated in large numbers in recent months may reflect the transition to less productive marine conditions.
- Although commercial fishery landings have remained high in recent years, the fishing fleet has become more specialized in terms of targeting specific fisheries. That may expose the vessels to more fluctuations of catch and revenue if those fisheries decline.

Deep-water marine fish living on the continental slopes at depths from 2,000 feet to one mile have liver pathologies, tumors and other health problems that may be linked to human-caused pollution, one of the first studies of its type has found. Fish have been found with a blend of male and female sex organs including. The findings appear to reflect general ocean conditions.

Most efforts to protect and restore wetlands mistakenly focus on preserving only total wetland area, with no consideration of ecosystem services provided by different wetland types, according to a new study from the University of Waterloo. The study, published in the peer-reviewed journal Ecological Applications last month, shows wetland loss follows a strong pattern, with smaller, isolated wetlands being lost in much greater numbers than larger wetlands. ….not only have we drained large numbers of smaller, isolated wetlands, but that the remaining wetlands have much simpler shapes, leading to an extensive loss of wetland perimeter. It has been shown that wetland perimeters provide important habitat for aquatic species and allow for more chemical reactivity to improve water quality. Smaller wetlands also function best as a group, forming an interconnected “landscape mosaic” which provide unique habitat and safe breeding grounds for species such as salamanders and migratory birds. As described in another recent paper by Basu in the journal Bioscience, these small, geographically isolated wetlands act like landscape filters, preventing excess nutrients, sediments and contaminants from entering larger waterways. Unfortunately, many restoration efforts have focused simply on restoring wetland area, with no consideration of the type or size of the wetlands being restored. “We didn’t expect to see such a strong, preferential loss of smaller wetlands,” says Basu, who is also cross-appointed with Civil and Environmental Engineering and a member of the Water Institute. “It’s not just a local phenomenon. Smaller wetlands are the least protected under most environmental regulations.”

Marijuana (Cannabis sativa L.) cultivation has proliferated in northwestern California since at least the mid-1990s. The environmental impacts associated with marijuana cultivation appear substantial, yet have been difficult to quantify, in part because cultivation is clandestine and often occurs on private property. To evaluate the impacts of water diversions at a watershed scale, we interpreted high-resolution aerial imagery to estimate the number of marijuana plants being cultivated in four watersheds in northwestern California, USA. Low-altitude aircraft flights and search warrants executed with law enforcement at cultivation sites in the region helped to validate assumptions used in aerial imagery interpretation. We estimated the water demand of marijuana irrigation and the potential effects water diversions could have on stream flow in the study watersheds. Our results indicate that water demand for marijuana cultivation has the potential to divert substantial portions of streamflow in the study watersheds, with an estimated flow reduction of up to 23% of the annual seven-day low flow in the least impacted of the study watersheds. Estimates from the other study watersheds indicate that water demand for marijuana cultivation exceeds streamflow during the low-flow period. In the most impacted study watersheds, diminished streamflow is likely to have lethal or sub-lethal effects on state-and federally-listed salmon and steelhead trout and to cause further decline of sensitive amphibian species.

NRCS swiftly launched the Migratory Bird Habitat Initiative following the 2010 Deepwater Horizon oil spill to enable farmers to create and enhance habitat for migratory birds, providing an alternative to habitat in impacted coastal ecosystems. NRCS invested $40 million in the initiative, which led to conservation practices implemented on more than 470,000 acres in Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, Missouri and Texas. Mississippi State University completed a three-year evaluation of bird use of habitat and availability of food in rice fields, catfish ponds and wetlands managed through MBHI. The results were released in a report in fall 2014=Download the report to learn more. (PDF, 795KB). This report includes findings that demonstrate the importance of landscape-level conservation efforts. The evaluation began in November 2010. The study’s findings demonstrate:
- Rice fields flooded early through MBHI were home to an average 15 migratory birds per acre, compared to two birds per acre on rice fields not flooded;
- Catfish ponds flooded early showed heavy biodiversity with 40 species of ducks, shorebirds and other waterbirds visiting them;
- Over seven times more migrating shorebirds were observed on shallowly flooded idled catfish ponds enrolled in MBHI than on other catfish ponds;
- MBHI-enrolled catfish ponds in Mississippi met nearly all the established shorebird migration habitat goal for the region; and
- MBHI-managed habitats provided up to 28 percent of the winter waterfowl food energy needed in the Mississippi Delta and up to 25 percent needed in southwestern Louisiana.

Researchers Michel M. Maharbiz and Hitoko Sato strapped tiny computer and radios on the back of beetles for their experiments.Two researchers curious about how insects actually fly have been strapping computers and radios on the backs of beetles in a UC Berkeley lab and watching them twist and turn and hover in the air. A UC Berkeley electrical engineer and a former graduate student in his lab had two goals in mind when they began their experiment seven years ago:
•To study the beetles’ muscles as a key to investigating the mysteries of insect flight;
•And to see if the research experiments might help in building tiny flying robots, small enough to flit through open windows or caves or ruined buildings, for a variety of missions such as search-and-rescue operations.
ASSOCIATED PRESS March 21, 2015 ADDIS ABABA, Ethiopia — Black smoke billowed into the air of the Ethiopian capital Friday as 6.1 tons of illegal elephant tusks, ivory trinkets, carvings and various forms of jewelry went up in flames on a wooden pyre. Government officials had started the blaze to discourage poaching and the ivory trade.
Ethiopia becomes the second African country this year to burn its ivory stockpile as global efforts increase for the conservation of elephants, a vulnerable species whose numbers are quickly dwindling as they are killed for their ivory tusks. Dawud Mome, Director General of the Ethiopian Wildlife and Conservation Authority, said the ivory was confiscated from various people in the last 20 years. Most of the ivory was being smuggled through Ethiopia to a third country, he says. “Poaching is increasingly becoming a major concern in our country,” he said, adding that the contraband was seized in collaboration with local police and Interpol. Since 2010, 734 people have been arrested for connections with the illegal ivory trade, the majority of them Chinese nationals passing through Bole International Airport in Addis Ababa, the African Wildlife Foundation said in a statement. Abate Tulu, an official from Ethiopia’s wildlife authority, said the country’s elephant population was more than 15,000 in the 1970s but the poaching scourge in the eighties’ decimated the herds. Ethiopia currently has only 1,900 elephants and the wildlife authority says the poaching threat persists. Kenya destroyed 15 tons of ivory recovered from poachers and smuggler earlier this month. Gabon, China, U.S. among others have also destroyed their ivory stockpiles in the past years, said Kenyan elephant expert Patrick Omondi. Save The Elephants said last year that 100,000 elephants were killed in Africa between 2010 and 2012. Last month, China imposed a one-year ban on ivory imports amid criticism that its citizens’ huge appetite for ivory threatens the existence of Africa’s elephants.
Cordell Bank National Marine Sanctuary, located 42 miles north of San Francisco, will expand from 529 square miles to 1,286 square miles. Gulf of the Farallones National Marine Sanctuary will expand from 1,282 square miles to 3,295 square miles of ocean and coastal waters. (NOAA)

Well, at least someone in the Bay Area is getting more housing. Two marine sanctuaries off the coast of Northern California are more than doubling in size under a federal agency decision announced Thursday. The National Oceanic and Atmospheric Administration announced Gulf of the Farallones National Marine Sanctuary will now extend from south of the islands, whose jagged granite peaks can be seen on the clearest of days from the mainland, to the waters off Point Arena, in Mendocino County. Currently, the northern edge of the protected waters is off Bodega Bay. The Farallones sanctuary will grow from 1,282 square miles to 3,295 square miles. The adjoining Cordell Bank National Marine Sanctuary, northwest of the Golden Golden Gate, will be extended westward into the Pacific and grown from 529 to 1,286 square miles. The sanctuary will be off-limits to oil drilling, and large industrial developments cannot set up shop along the coastline to use ocean water. In total, more than 2,700 square miles are being added to sanctuaries. A nutrient-rich upwelling zone originating off Point Arena makes this region an incredibly productive ecosystem. The varied habitats within the sanctuaries support a wide range of sea life, including 25 endangered or threatened species, thousands of breeding seabirds and one of the most significant white shark populations on the planet. Not into sharks? Fear not. There are a lot of cute things in these waters, too. Among the 36 types of marine mammals you’ll find are blue, gray and humpback whales, harbor seals, elephant seals, Pacific white-sided dolphins and Steller sea lions. “This expansion is the outcome of a tremendous collaborative effort by government, local communities, academia and elected officials to provide additional protection for critical marine resources,” said Daniel J. Basta, director of NOAA’s Office of National Marine Sanctuaries, in a press release. “It presents a bold vision for protecting the waters off the Northern California coast for current and future generations.” The boundaries of the expansion are final, and will go into effect after a 45-day congressional review period.

A ubiquitous type of phytoplankton — tiny organisms that are the base of the marine food web — appears to be suffering from the effects of ocean acidification caused by climate change.
According to authors of a new study, the single-celled organism under study is a type of “calcifying” plankton called a coccolithophore, which makes energy from sunlight and builds microscopic calcium carbonate shells, or plates, to produce a chalky suit of armor….The coccolithophore E. huxleyi is important in the marine carbon cycle and is responsible for nearly half of all calcium carbonate production in the ocean, said lead study author Natalie Freeman, a doctoral student in the CU-Boulder’s Department of Atmospheric and Oceanic Sciences (ATOC). The new study indicates there has been a 24 percent decline in the amount of calcium carbonate produced in large areas of the Southern Ocean over the past 17 years.… NOAA scientists have estimated that global oceans have become up to 30 percent more acidic since the Industrial Revolution. “While we generally expect acidification to negatively impact coccolithophore calcification and growth, other environmental stressors such as warming may have influenced these processes,” said Lovenduski. The two researchers, who also are affiliated with CU-Boulder’s Institute of Arctic and Alpine Research, used data collected by the SeaWiFS and MODIS satellite instruments. “These results suggest that large-scale shifts in the ocean carbon cycle are already occurring and highlight organism and marine ecosystem vulnerability in a changing climate,” wrote the CU-Boulder researchers in GRL.

Arctic sea ice has been in a virtual death spiral for over three decades now with serious implications for extreme weather, sea level rise, and permafrost melt. Not only has the surface area or extent of sea ice declined sharply, but so has the ice thickness during the summer minimum (when the melt season ends in September) — dropping a remarkable 85 percent from 1975 to 2012, according to a recent study. The extent of Arctic sea ice hits a winter maximum in early March. This year, the National Snow and Ice Data Center (NSIDC) — along with NOAA and NASA — said the maximum extent was likely reached on February 25. This was not only the second earliest maximum, “it is also the lowest in the satellite record.”….As NASA points out, this record low winter maximum does not guarantee a record summertime minimum. Moreover the maximum is less significant than the minimum. “Scientifically, the yearly maximum extent is not as interesting as the minimum. It is highly influenced by weather and we’re looking at the loss of thin, seasonal ice that is going to melt anyway in the summer and won’t become part of the permanent ice cover,” explained NASA sea ice scientist Walt Meier. “With the summertime minimum, when the extent decreases it’s because we’re losing the thick ice component, and that is a better indicator of warming temperatures.” The best indicator of the sustained impact of global warming on the Arctic is the stunning decline in the thickness of the sea ice that has accompanied the shrinking of its surface area. A February study published in The Cryosphere, “Arctic sea ice thickness loss determined using subsurface, aircraft, and satellite observations,” offers the most comprehensive and up-to-date analysis of the Arctic death spiral, combining eight different data sets, including ones from submarines, aircraft, and satellites. This study’s conclusion is alarming:
… annual mean ice thickness has decreased from 3.59 meters [11.8 feet] in 1975 to 1.25 m [4.1 feet] in 2012, a 65% reduction. This is nearly double the 36% decline reported by an earlier study….
In September the mean ice thickness has declined from 3.01 to 0.44 m [from 9.9 to 1.4 feet!], an 85 % decline. “The ice is thinning dramatically,” explained climatologist Ron Lindsay, the lead author — much faster than previously estimated… Summertime Arctic sea ice is not long for this world. Because of Arctic amplification, the Arctic warms twice as fast (or more) than the Earth as a whole does. Earlier this month, a study projected the rate of warming for the Arctic will soon exceed 1.0°F (0.55°C) per decade — and could hit 2°F per decade post-2050 if we don’t reverse carbon pollution trends ASAP. This is especially troublesome because a key accelerator of Arctic amplification is sea ice loss.
Global warming melts highly reflective white ice and snow, exposing in its place the dark blue sea or dark land, both of which absorb much more solar energy. A great deal of recent research suggests that Arctic amplification, including sea ice loss, is already worsening extreme weather. Similarly, such amplified warming means that the rapidly-melting Greenland ice sheet, which warming has already made unstable, is likely to start collapsing even faster, which would push sea level rise higher than previously estimated, upwards of six feet this century. Finally, a 2008 study, “Accelerated Arctic land warming and permafrost degradation during rapid sea ice loss,” concluded that “simulated western Arctic land warming trends during rapid sea ice loss are 3.5 times greater than secular 21st century climate-change trends. The accelerated warming signal penetrates up to 1500 km [930 miles] inland.” So our current period of rapid sea ice loss threatens to triple Arctic land warming, which would speed up the release of large amounts of carbon from defrosting permafrost — a dangerous amplifying feedback which could add as much as 1.5°F to total planetary warming this century.
The 2°C target has been said to carry an increased risk of sea level rise, shifting rainfall patters and extreme weather events such as floods, droughts, and heat waves.Credit: © meryll / Fotolia[Click to enlarge image]

The official global target of a two degree Celsius temperature rise is ‘utterly inadequate’ for protecting those at most risk from climate change, says an expert. The commentary presents a rare inside-view of a discussion at the Lima Conference of the Parties on the likely consequences of accepting an average global warming target of 2 degrees Celsius versus 1.5 degrees Celsius. The official global target of a 2°C temperature rise is ‘utterly inadequate’ for protecting those at most risk from climate change, says a lead author on the Intergovernmental Panel on Climate Change (IPCC), writing a commentary in the open access journal Climate Change Responses. The commentary presents a rare inside-view of a two-day discussion at the Lima Conference of the Parties (COP) on the likely consequences of accepting an average global warming target of 2°C versus 1.5°C (measured from pre-industrial times until 2100). The discussions were part of the United Nations Framework Convention on Climate Change (UNFCCC) ‘structured expert dialogue’ in December 2014. They reveal unevenly distributed risks and political power differentials between high-income countries insisting on a 2°C target and low- and many middle-income countries pushing for 1.5°C or lower. The 2°C target has been said to carry an increased risk of sea level rise, shifting rainfall patters and extreme weather events such as floods, droughts, and heat waves, particularly targeting the Polar Regions, high mountain areas, and the Tropics. The author Petra Tschakert from The Pennsylvania State University and a coordinating lead author of the IPCC’s Fifth Assessment Report says: “The consensus that transpired during this session was that a 2°C danger level seemed utterly inadequate given the already observed impacts on ecosystems, food, livelihoods, and sustainable development….”A low temperature target is the best bet to prevent severe, pervasive, and potentially irreversible impacts while allowing ecosystems to adapt naturally, ensuring food production and security, and enabling economic development to proceed in a sustainable manner.”
In her commentary, Tschakert explains that the target of keeping the global average temperature rise to below 2°C originates from early studies in the 1970s. This target became anchored in policy debates over the decades, and was officially sanctioned as the long-term global goal for greenhouse gas emission reductions at the COP15 in Copenhagen in 2009. Despite support from high and upper middle-income countries with high emissions, the 2°C target has been subject to repeated criticism from climate scientists, economists, and political and social scientists. Alliances representing over 70% of the parties around the table, including over 100 low- and middle-income countries and small island states, have repeatedly said that a 2°C rise is unsafe for their communities, and insist on a long-term goal to keep global average temperatures below 1.5°C. These states include the Pacific nation of Tuvalu that was recently hit by Cyclone Pam. While the 2°C target is now being re-evaluated, no reference to an explicit 1.5°C target is included in the 2014 Lima Call for Climate Action, despite specific remarks on the lower temperature limit being made throughout the negotiations.
….In terms of ecosystems, it was said that limiting warming at 1.5°C could keep sea level rise below 1m, saving half of the world’s corals, and leave some of the Arctic summer ice intact. Tschakert says: “These implications emphasize what is truly at stake — not a scientific bickering of what the most appropriate temperature target ought to be, but a commitment to protect the most vulnerable and at risk populations and ecosystems, as well as the willingness to pay for abatement and compensation. This should happen now, and not only when climate change hits the rich world.” The findings are timely as the long-term goal to stay below 2°C warming is currently undergoing a 2013-15 Review, the results of which are expected this June and could be adopted in Paris at COP21 in December 2015. Tschakert concludes in her commentary: “The crux of the matter is no longer about the scientific validity of one temperature target over another… It is first and foremost about overcoming deeply entrenched divisions on value judgments, responsibility, and finance… It is about acknowledging that negative impacts of climate change under a 0.8°C temperature increase are already widespread, across the globe, and that danger, risk, and harm would be utterly unacceptable in a 2°C warmer world, largely for ‘them’ — the mollusks, and coral reefs, and the poor and marginalized populations… even if this danger hasn’t quite hit home yet for ‘us‘.”

Reef-building corals, already thought to be living near their upper thermal limits, are experiencing unprecedented declines as the world’s oceans continue to warm. New evidence from scientists at Florida Institute of Technology shows there may be some climate refuges where corals will survive in the future. The study appears in the March issue of Global Change Biology…

Natural wetlands usually emit methane and sequester carbon dioxide. Anthropogenic interventions, in particular the conversion of wetlands for agriculture, result in a significant increase in carbon dioxide emissions, which overcompensate potential decreases in methane emission. A large international research team now calculated that the conversion of arctic and boreal wetlands into agricultural land would result in an additional cumulative radiative forcing of about 0.1 mJ per square meter for the next 100 years…The conversion of temperate wetlands into agricultural land would even result in a cumulative radiative forcing of 0.15 mJ per square meter. Converting forested wetlands into managed forests also contributes to increased warming, albeit much less than the conversion of non-forested wetlands….Wetlands are unique ecosystems, which — under natural conditions — are the single largest natural source of the greenhouse gas methane (CH4) but at the same time an important sink for the greenhouse gas carbon dioxide (CO2). The climate footprint of these ecosystems depends on the balance of these two important greenhouse gases. Despite methane being 28 times more potent as a greenhouse gas than carbon dioxide (in a 100 year time span), the conversion of natural wetlands into agricultural or forested ecosystems and its associated decrease in methane emissions still leads to an overall warming effect. “The human impact on wetlands, such as drainage, results in a shift of the climate footprint of that wetland” says Torsten Sachs at the GFZ German Research Centre for Geosciences, co-author of the study. “The overall balance of these two differently active greenhouse gases and thus the climate footprint of a wetland over different time spans depend on the relative sign and magnitude of these ecosystem-atmosphere fluxes.” The global impact is still rather uncertain due to large temporal and spatial variability and a lack of data on the complex interactions between environmental drivers such as temperatures of land, water, and sediment, water levels, vegetation, nutrient availability, among others, and the additional anthropogenic impacts such as land use change.
ASSOCIATED PRESS March 21, 2015 NEW DELHI — The world could suffer a 40 percent shortfall in water in just 15 years unless countries dramatically change their use of the resource, a U.N. report warned Friday. Many underground water reserves are already running low, while rainfall patterns are predicted to become more erratic with climate change. As the world’s population grows to an expected 9 billion by 2050, more groundwater will be needed for farming, industry and personal consumption. The report predicts global water demand will increase 55 percent by 2050, while reserves dwindle.
If current usage trends don’t change, the world will have only 60 percent of the water it needs in 2030, it said.
Having less available water risks catastrophe on many fronts: Crops could fail, ecosystems could break down, industries could collapse, disease and poverty could worsen, and violent conflicts over access to water could become more frequent. “Unless the balance between demand and finite supplies is restored, the world will face an increasingly severe global water deficit,” the annual World Water Development Report said, noting that more efficient use could guarantee enough supply in the future. The report, released in New Delhi two days before World Water Day, calls on policymakers and communities to rethink water policies, urging more conservation as well as recycling of wastewater as is done in Singapore. Countries may also want to consider raising prices for water, as well as searching for ways to make water-intensive sectors more efficient and less polluting, it said. In many countries including India, water use is largely unregulated and often wasteful. Pollution of water is often ignored and unpunished. At least 80 percent of India’s population relies on groundwater for drinking to avoid bacteria-infested surface waters. In agriculture-intense India, where studies show some aquifers are being depleted at the world’s fastest rates, the shortfall has been forecast at 50 percent or even higher. Climate change is expected to make the situation worse, as higher temperatures and more erratic weather patterns could disrupt rainfall.
About 748 million people worldwide now have poor access to clean drinking water, the report said, cautioning that economic growth alone is not the solution — and could make the situation worse.

By Peter Fimrite SF Chron Updated 8:06 pm, Friday, March 27, 2015
The abominable snowpack in the Sierra Nevada reached an unprecedented low this week, dipping below the historic lows in 1977 and 2014 for the driest winter in 65 years of record-keeping.
Electronic surveys show the water content of the snow throughout the Sierra is a shocking 8 percent of the historical average for this time of year, by far the driest it has been since 1950 because of the lack of rain and snowfall and the exceedingly high temperatures. It is a troubling milestone that water resources officials say is bound to get even lower as the skies remain stubbornly blue. “It’s certainly sobering when you consider that the snowpack in a normal year provides about 30 percent of what California needs in the summer and fall,” said Doug Carlson, the spokesman for the California Department of Water Resources. “What this suggests is that we will have very little water running off. It accentuates the severity of the drought and emphasizes the importance of people cutting back on their water use.” The department is planning to conduct its monthly snow survey on April 1, the date water resources officials use as a benchmark because it is when the snowpack normally begins to melt and fill up the state’s reservoirs. Meteorologists see nothing on the horizon that could pull the state out of its increasingly frightful drought. The snowpack is already far below the historic low, which happened in 1977 and again last year, when the snowpack was 25 percent of normal on April 1.
The surveyors measure the depth and water content of the snow in 230 places, called snow courses, in the mountains stretching from north to south. Their results are combined with electronic measurements taken from as many as 130 places around the Sierra to calculate California’s drinking water supply for the year. The state has been publishing statewide snowpack measurements in the Sierra since 1950, but there are several places where measurements go back as far as 1926. At Phillips Station, near the Sierra-at-Tahoe resort, an average of 66.5 inches of snow is normally on the ground on April 1. “We don’t expect to find any snow up there on Wednesday,” Carlson said Friday. “It’s pretty spooky.” The snow in the Sierra has been declining since the first snow survey on December 30, when electronic readings found the statewide snow water content was 50 percent of normal for that date. That survey followed several storms in December But the readings plummeted to 25 percent of average on Jan. 29 and 19 percent of average on March 3. The measurements are important because snow makes up 60 percent of the water that is captured in California’s reservoirs when it melts in the spring and 30 percent of the state’s overall water supply during a normal year. Curiously, California’s biggest reservoirs have managed to hold steady despite the dismal snowpack. Shasta Lake, the state’s largest reservoir, has 74 percent of what it normally holds at this time of year. Lake Oroville, the second-largest reservoir and the most important source for the State Water Project, is carrying 67 percent of what it normally holds at this time of year. Shasta and Oroville carry 80 percent of the state’s reservoir supply. The water is used to irrigate 8 million acres of farmland and quench the thirst of close to 30 million people. The problem, experts say, is that the reservoirs will not be getting much additional supply from snow melt, a crucial source in California’s dry Mediterranean summer climate. Meanwhile, the reservoirs that serve farming communities are wretchedly low. Pine Flat Dam, on the Kings River, is only 32 percent of normal, and Exchequer, or McClure Dam, on the Merced River, stands at only 16 percent of normal. Some of the smaller reservoirs are in real danger of going completely dry this summer.
Thirsty crops should require state regulation
L.A. Times, George Skelton March 23, 2015
This is what the Brown administration OPINION isn’t talking about as it tightens the spigot on landscaping: Urban use accounts for only 20% of California’s developed water. Agriculture sucks up 80%. Some calculate it a little differently: 10% urban, 40% agriculture and 50% environment — meaning every drop in the rivers and marshes. Same thing. Yet, no one in Sacramento wants to tell farmers how to use water — what they can and cannot plant and irrigate. No edicts equivalent to “lawn-watering only twice a week” or “hosing down the driveway is forbidden.” No such directives as “tomatoes are OK because they’re not water guzzlers and can be fallowed in a dry year,” but “hold off planting more gulping almond orchards in the desert.”
Maybe, however, it’s time for state government to consider regulating crops based on their water needs as California’s drought lingers menacingly and we head into the uncertain future of global warming. After all, we think nothing of telling other landowners what they can put on their property. We don’t allow a new housing tract to sprout unless the developer can identify a source of water. We zone everything in urban areas — requiring government permission to build a house, a strip mall, a factory or a refinery. Yet, a farmer can plant whatever he pleases, even if surface water is flowing at a trickle and the aquifer is collapsing. This is what Times water reporter Bettina Boxall wrote last week: “Parts of the San Joaquin Valley are deflating like a tire with a slow leak as growers pull more and more water from the ground. “The land subsidence is cracking irrigation canals, buckling roads and permanently depleting storage space in the vast aquifer that underlies California’s heartland … hastening the day, experts warn, when [farmers] will be forced to let more than a million acres of cropland turn to dust…. [But] it’s easier for growers to keep pumping than rein in their use.” In one area of the San Joaquin Valley, Boxall reported, the “land has been sinking at the staggering rate of a foot a year.” And the groundwater table has plunged 150 feet in the last 15 years. There’s no longer a drought buffer….
Photo: Rich Pedroncelli / Associated Press The California Aqueduct has sent water from Northern California to Southern California, sometimes to the detriment of native fish populations, for decades.
By Jay Lund and Peter Moyle SF Chron OPINION March 20, 2015 Updated: March 20, 2015 3:45pm
The California Aqueduct has sent water from Northern California to Southern California, sometimes to the detriment of native fish populations, for decades. When labor is scarce, people move to better jobs with higher wages. When land is scarce, landowners are offered higher prices for its use. When drought makes water scarcer in California, those with senior water rights are offered more money to move their water to other users. But fish are asked to give up their water for free.
California would do better if it cultivated a more civilized ethic where there is no free water during a drought. Perhaps we should treat environmental uses of water more as a matter of economics, to help the environment and the economy.
This year and last year, the State Water Resources Control Board relaxed environmental protections for fish to export more water from the Sacramento-San Joaquin River Delta for farms and cities. Reducing fish flows without compensation during a drought has some attractions, but overall seems like a risky idea. On the plus side, it’s a principle that, during a drought, everyone should get less water, including the environment. The reality is that some small reductions in environmental flows may not harm fish, but would have great economic value to cities and farms. Variability in flows is natural for many of California’s native ecosystems. Droughts might provide useful variability, if properly managed. However, reductions in environmental flows during drought usually have costs, including:
•Potential direct harm to fish in the short term, and in the longer term, severely reducing native fish populations and sometimes making it easier for invasive species to become established.
•Risks that additional native fish or other aquatic species will become legally listed as threatened or endangered, which can reduce long-term water withdrawals for economic water uses.
•Encouraging water fights, rather than using negotiation or markets to rebalance and reallocate water. This is uncivilized and encourages greater conflicts over water.
The amount of environmental flows that cities and farms will gain this year is relatively small, about 40,000 acre-feet of water. But in a drought year, 40,000 acre-feet of water south of the delta is probably worth more than $1,000 an acre-foot or about $40 million. While this is a tiny proportion of agricultural production or urban economies, those next in line for this water will find it worth fighting for. The high value of small amounts of water during droughts is a harsh challenge for science, environmental advocates and those interested in thoughtful water policy. How can we make this a more civilized choice?
Let the fish sell their water. That is, convert some drought portion of environmental flows to a marketable water quantity, owned by the fish agencies. This would allow environmental water uses to be fairly compensated by those gaining from reductions in environmental flows, just as other high-priority water rights holders are compensated for their reductions in water use during a drought. This seems more fair, gives incentives to water users to behave better, and encourages conflicts to be speedily negotiated instead of indefinitely litigated…..
DWR Report Describes Past and Ongoing Droughts; A Wealth of Information in Comparison of California’s Worst Historical Droughts
Severe droughts are nothing new to California, home to the highest variable precipitation in the United States. In the midst of a fourth dry year, the California Department of Water Resources (DWR) has released an in-depth report comparing the severity and impacts of California’s most significant droughts, which stretched from 1929 to 1934, 1976 to 1977 and 1987 to 1992. The report also details the ongoing drought, which began in 2012. “California’s Most Significant Droughts: Comparing Historical and Recent Conditions,”…presents a wealth of information about California’s climate; federal, state, and local water systems; surface and groundwater resources; and historical precipitation. It also provides a summary of lessons learned from previous droughts and highlights the need for better data about groundwater conditions, improved drought prediction capability, and better drought preparedness for small water systems.
The report also describes:
- The atmosphere-ocean dynamics that influence drought in California;
- Highlights of past droughts, such as the extremely severe 1929-34 dry spell that occurred when irrigated acreage in the state was relatively small and the population was less than six million people;
- The setting for past droughts in terms of major water project development, population, and irrigated acreage in the state;
- Historical attempts to cope with drought, such as the temporary emergency pipeline constructed across the San Rafael Bridge to bring imported water to southern Marin County in 1976-77;
- Estimated economic loss data, where available, from the historical droughts, including farmland fallowing and timberland destroyed by wildfire and bark beetle infestation;
- Changes in institutional settings that affect California’s response to drought, such as environmental protection laws that have modified water project operations; and
- Historical deliveries made by the State Water Project and the Central Valley Project from 1977 to the present.
The appendix of the report includes a copy of each gubernatorial executive order or emergency proclamation issued related to drought since 1977. Charts, maps, and graphs in the report illustrate such information as the at-risk small water systems around the state, a comparison of storage in key reservoirs during various drought years, changes in the Colorado River total system storage over time, changes in California’s statewide mean temperature departure since 1900, and maximum salinity intrusion into the Sacramento-San Joaquin Delta in previous droughts. The report was prepared by DWR Deputy Drought Manager and Interstate Resources Manager Jeanine Jones. “The water years of 2012-14 stand as California’s driest three consecutive years in terms of statewide precipitation,” said Jones, “and we do not know how long this drought will last. It’s important for Californians to remember that drought is a part of life in California and we can learn from history as we try to emerge from each drought better prepared for the next.” In January 2014, Governor Edmund G. Brown Jr. declared a drought state of emergency and asked Californians to voluntarily curb their water use by 20 percent. Vast tracts of farmland have been fallowed and some communities have been short on drinking water. Every Californian can help stretch the state’s limited supplies by using water carefully. Outdoor landscaping needs little water in the winter, so shut off sprinklers, especially for the first couple of weeks after a rain. Replace washers in leaking faucets or make other repairs to stop leaks. Run dishwashers and clothes washers only with full loads. For more water-saving tips, visit www.saveourwater.com.
March 27, 2015 Universidad Politécnica de Madrid
Researchers from Universidad Politécnica de Madrid and Università Politecnica delle Marche have found that green roofs with high vegetation density are 60% more efficient than non-green roofs. The main goal of this research conducted by the Universidad Politécnica de Madrid (UPM) and the Università Politecnica delle Marche (UNIVPM) was to show energy efficiency of green roofs. Researchers have developed a numerical model that was able to verify the effects on passive cooling of buildings caused by the density variation of vegetation of green roofs. With just an error between 5% and 7%, this model could be used to study the energy saving produced by these architectural elements….This study is focused on three specific aspects: to assess the impact of vegetation density on energy efficiency of a roof located at a Mediterranean coastal climate; develop a simplified numeral model that can estimate thermal resistance values equivalent to plants and substrates, and finally, to verify the numerical model by using experimental data. Results show that, when vegetation density is high, the incoming heat into the building through the roof is 60% lower than the incoming heat without vegetation.
Besides, researchers found that a roof with a high density vegetation works as a passive cooling system, in fact, the energy released from the building through the roof during the summer is a 9% of the incoming energy during the same period.
California first state to get 5 percent of electricity from solar
By David R. Baker SF Chron Updated 4:14 pm, Tuesday, March 24, 2015
California’s decade-long push to add solar power is showing some big results. The federal government reported Tuesday that California has become the first state to get 5 percent of its electricity from large-scale solar power installations. In 2014, solar power plants in California generated 9.9 million megawatt hours of electricity, more than all other states combined. And the report, from the U.S. Energy Information Administration, doesn’t even count the output of rooftop solar arrays on homes and many businesses. Only installations capable of generating at least 1 megawatt of electricity were included. California law requires utilities to get 33 percent of their electricity from renewable sources by 2020. That law prompted a wave of solar power plant construction that peaked in the last two years, with massive plants coming online. Some of those facilities —such as Topaz and Desert Sunlight — use the same photovoltaic panels that homeowners slap on their roofs. Others — including the Ivanpah plant designed by Oakland’s BrightSource Energy and funded by Google — employ fields of mirrors to focus sunlight (although questions about the amount of electricity Ivanpah actually generates continue to dog the plant)….
China’s vast manufacturing sector has fuelled its demand for energy
22 March 2015 Last updated at 07:10 ET
Climate change could have a “huge impact” on China, reducing crop yields and harming the environment, the country’s top weather scientist has warned, in a rare official admission.
Zheng Guogang told Xinhua news agency that climate change could be a “serious threat” to big infrastructure projects. He said temperature rises in China were already higher than global averages.
China, the world’s biggest polluter, has said its emissions of gases that cause climate change will peak by 2030.
However, the country has not set a specific target for cutting emissions of the gases, mainly carbon dioxide. Mr Zheng, the head of China’s meteorological administration, said warming temperatures exposed his country to a growing “risk of climate change and climate disasters”. He said temperature rises in China had already been higher than the global average for the past century. These are rare admissions from a Chinese official, BBC Asia analyst Michael Bristow says. China’s leaders have acknowledged the damage from global warming but they usually do not lay out the full scale of the problems. Mr Zheng warned of more droughts, rainstorms, and higher temperatures, which would threaten river flows and harvests, as well as major infrastructure projects such as the Three Gorges Dam. He urged China to pursue a lower-carbon future. “To face the challenges from past and future climate change, we must respect nature and live in harmony with it,” the Xinhua news agency quoted him as saying. “We must promote the idea of nature and emphasise climate security.”
China and the US together produce around 45% of global carbon emissions.
Leaders from the two countries are taking part in a summit in Paris this year that will aim for a global deal to cut carbon emissions by 2020.
China’s decades-long pursuit of rapid economic growth has boosted demand for energy, particularly coal.
Scientists fear that pledges made so far to cut emissions will not be enough to avoid the harmful impact of climate change….
- Draft Final Desalination Amendment with Draft Final Staff Report with Substitute Environmental Documentation was released March 20, 2015
- Updated Fact Sheet available here: Fact Sheet
State Water Board staff is developing an amendment to the Ocean Plan that would address issues associated with desalination facilities (Desalination Amendment). Desalination facilities and brine disposal were identified as Issue Number 4 in the 2011-2013 Triennial Review Workplan because several new desalination facilities have been planned along the California coast to augment existing water supplies. The operation and construction of desalination facilities can result in marine life mortality and harm to aquatic life beneficial uses. During the process of ocean desalination, organisms may be drawn in with the source water and enter the facility’s water processing system. Salt and minerals are removed from salt water to produce fresh water and organisms do not survive the desalination process. The salt, minerals, and other compounds produced as a by-product of desalination are discharged into the ocean as hyper-saline brine. Brine is denser than the receiving ocean water and, depending on discharge methods, may settle on the seafloor and have adverse effect on marine organisms. Currently, the Water Boards regulate brine discharges from these types of facilities through the issuance of National Pollutant Discharge Elimination System (NPDES) permits that contain conditions protective of aquatic life. However, the Ocean Plan does not yet have an objective for elevated salinity levels in the ocean, nor does it describe how brine discharges are to be regulated and controlled, leading to permitting uncertainty. The Ocean Plan also does not address possible impacts to marine life from new intakes for desalination facilities. The State Water Board is considering amendments to the Ocean Plan that would address desalination facilities. The proposed Desalination Amendment would include components that: 1) clarify the State Water Board’s authority over desalination facility intakes and discharges, 2) provide direction to the regional water boards regarding the determination required by California Water Code section 13142.5, subdivision (b) (hereafter 13142.5(b)), 3) include implementation provisions for a statewide narrative receiving water limitation for salinity, and an option for dischargers to apply for a facility-specific receiving water limitation, and 4) include monitoring and reporting requirements…

- The state Senate will consider a $1-billion spending plan billed as an emergency response to the drought
- State Senate passes emergency drought relief plan; bill goes before Assembly
The legislation now goes to the Assembly, which is scheduled to take up the issue on Thursday before it goes to Gov. Jerry Brown for his signature. If enacted, the proposal would fund upgrades to the state’s water infrastructure and provide food and water to struggling Central Valley communities. Sen. Lois Wolk (D-Davis) called the legislation “step one” in addressing the drought. However, the largest chunk of money, $660 million, would be spent on new flood control projects, not responding to the drought itself. That funding comes from a bond measure approved by voters a decade ago. “We’re, as they say, taking advantage of a crisis and moving forward,” Brown explained when announcing the proposal last week.Only $27.4 million outlined in the legislation is new spending that wasn’t included in previous budget proposals or bond measures. In addition, many of the projects being funded won’t be finished for year…

The California Department of Fish and Wildlife (CDFW) has completed its draft Deer Conservation and Management Plan, which is now available for public comment and review. The plan can be found at www.dfg.ca.gov/wildlife/hunting/deer/ .
CDFW is proposing to develop 10 large-scale deer conservation units, which will assess how recent landscape and environmental changes have impacted deer population and habitat. The draft plan also covers five important areas: unit plans, population management, habitat conservation, monitoring and outreach. Each unit will prepare separate plans, which will also be available for public comment and review at a future date. In addition, movement corridors, winter and summer ranges and holding areas will be mapped and used to develop long-term conservation objectives. Areas needing restoration or rehabilitation will also be prioritized in order of importance to conservation and management objectives. The deadline for comments is April 30, 2015. Interested parties can submit comments via email at DeerPlan@wildlife.ca.gov, or by regular mail sent to Deer Plan, 1812 Ninth St., Sacramento, CA 95811.
Michael Macor / The Chronicle A very new wind turbine, which produces more power and kills fewer birds, stands above a group of old-style wind turbines off Dyer Road near Livermore.
No more excuses to kill birds
SF Chronicle Editorial March 23, 2015
There is no better symbol of Californians’ efforts to save the Earth than the thousands of wind turbines on Altamont Pass near Livermore, the largest such concentration in the world. Yet the whirling blades, which produce clean power and reduce our reliance on oil, initially proved deadly for Earth’s creatures. Three of the four Altamont wind farm operators in Alameda County are on track to replace the bird-whacking models by October 2015 with taller, slower-turning blades that generate more power and kill far fewer birds. The fourth and the second largest, Altamont Winds Inc., will appeal to the Alameda County Board of Supervisors on Tuesday for permission to operate its old windmills for three more years. The supervisors must vote no.
Altamont Winds has received conditional use permits in the past to continue operating with the understanding it would phase out 15 percent of its 920 turbines a year. If it had kept to that agreement, it would have decommissioned the old machines by 2015. Instead, it reneged on the deal twice and still has 828 old-generation turbines. Altamont Winds says it needs the permits extended to 2018 to have enough revenue to fund the replacement work. The other three companies, operating under a 2007 settlement of a lawsuit brought by environmental groups, are well on the way to replacing their old turbines. Repowering, as the replacement process is called, does require significant financial investment to take down the older models, and then site and install new turbines away from avian flyways. It also has benefits: One new turbine can generate as much power as 10 to 30 of the old; repowering would create jobs. For the bats and birds, re-powering is essential: It cuts mortality rates by 60 to 80 percent. Wind farms are valuable: The state requires 33 percent of California’s power come from renewable resources; the governor wants to go to 50 percent.
Google is investing in renewable energy. The East County zoning board gave the request a thumbs-down, prompting the appeal. U.S. Fish and Wildlife Service, Audubon California, the East Bay Regional Park District, and state Attorney General Kamala Harris have objected. An extension rewards bad behavior, creates inequalities with the operators who are repowering, and puts Alameda County at legal risk: It is illegal under state and federal laws to kill the raptors most often felled by the blades: golden eagles, red-tailed hawks, American kestrels and burrowing owls. Few buy this unreasonable excuse for more delay. The supervisors shouldn’t either.
Wildlife rehabilitation technician Lauren Adams captures a surf scoter that’s still recovering from the January spill to give it a medical examination at the International Bird Rescue center in Fairfield. Hundreds of birds died after a non-petroleum-based substance polluted the bay, contaminating their feathers. Because the goo wasn’t oil, the response was hampered.
Resources target only oil, fuel spills; senators’ bill aims to erase that limit
By Peter Fimrite SF Chron March 23, 2015
Two California senators, angered by the tepid reaction to a mystery goo that has killed hundreds of birds on San Francisco Bay, are introducing legislation Monday to close a loophole that effectively froze state funding and prevented a unified multiagency response to the crisis. Sens. Mark Leno, D-San Francisco, and Loni Hancock, D-Berkeley, say SB718 would create a funding mechanism for the rescue and rehabilitation of wildlife harmed by marine spills involving non-petroleum-based substances. California’s system for handling oil spills is considered one of the nation’s most sophisticated, but no money or resources are available when something other than oil or fuel is spilled. The bill, co-sponsored by San Francisco Baykeeper and Audubon California, would authorize the California Department of Fish and Wildlife’s Office of Spill Prevention and Response to borrow up to $500,000 from the state’s oil disaster fund during spills that don’t involve petroleum. It is an effort to improve the response and bolster care for birds and wildlife slimed by unidentified substances like the sticky goop that circulated around the bay in mid-January, killing at least 320 aquatic birds.
… “It surprised many of us that there was no immediate state response, and assistance fell on nonprofits like the International Bird Rescue organization. That caused a delay in the rescue and rehabilitation of this wildlife and was a burden for these nonprofits,” Leno said. “Responsible parties should step forward. They don’t always do so. In the meantime, wildlife needs our attention and they need it quickly.” The goo, which has been identified as a nonpetroleum-based oil or fat, coated more than 600 birds, mostly along the Alameda, San Leandro and Hayward shorelines. The International Bird Rescue center in Fairfield treated and released 154 birds and is still caring for 19 gunked-up waterfowl. About 170 birds were found dead on the shore, and an additional 150 died in treatment. Wildlife advocates say many others probably died out at sea. …. “This legislation clarifies that the state’s top priority during a spill of any kind is to immediately protect waterways and wildlife, regardless of what type of substance caused the problem,” Leno said.
In 2007, the container ship Cosco Busan sideswiped the Bay Bridge and spilled more than 50,000 gallons of fuel oil into the bay. The disaster caused an uproar after it was revealed that miscommunication and foot-dragging allowed nearly an entire day to pass without attempts to contain the spill, which was initially believed to be smaller. Some 26 miles of shoreline were coated with oil, and an estimated 6,849 birds and thousands more fish were killed. The spill cost about $70 million to clean up. The incident prompted officials to improve training, planning and communications in preparation for the next bay emergency, which came in 2009 when the Panamanian tanker Dubai Star spilled bunker fuel south of the Bay Bridge. This time there was a four-hour gap between the time the spill was reported and the time booms were placed around the ship — time for black oil to disperse and wash ashore, authorities said. The response was better in 2013 when another tanker crashed into the foot of one of the Bay Bridge towers. No oil was spilled, but the response was immediate and comprehensive. California’s oil spill program is a product of the federal Oil Pollution Act of 1990, passed a year after the Exxon Valdez disaster in Alaska’s Prince William Sound. It requires oil tankers and other ships to, among other things, hire cleanup managers in case of an accident. The law requires ship owners to outline oil spill prevention and response plans, have enough insurance to cover up to $1 billion in damage, and designate a management company and “oil spill response organization” to clean up in the event of an accident. … The bottom line, he said, is that “if there is some sort of contaminant affecting wildlife, there should be some sort of fund or help for us to deal with it.”The bill is expected to be heard in policy committees this spring. Meanwhile, the Department of Fish and Wildlife is conducting more laboratory tests in an attempt to identify the substance that fouled the bay this winter. Once that is done, it is hoped, authorities will be able to identify the culprit.

Multi-benefit projects are designed to reduce flood risk and enhance fish and wildlife habitat by allowing rivers and floodplains to function more naturally. These projects create additional public benefits such as protecting farms and ranches, improving water quality, increasing groundwater recharge, and providing public recreation opportunities, or any combination thereof. In 2012, California’s Central Valley Flood Protection Board adopted the Central Valley Flood Protection Plan (CVFPP), which established a new framework for system-wide flood management and flood risk reduction in the Sacramento and San Joaquin River Basins. The CVFPP takes a new approach to flood protection that works with communities to improve flood safety while also supporting other public benefits such as clean water, natural areas that support fish and wildlife, and recreational areas in Central Valley communities where people can enjoy nature’s benefits. The CVFPP aspires to improve flood protection for over one million people and $70 billion in homes, businesses and infrastructure with the objective of providing 200-year flood protection to urban areas while reducing flood risks to small communities and agricultural lands. This site is a resource to support a multi-benefit approach to improving flood protection, meant for everyone working to make the CVFPP a success.
Q: What is 200-year flood protection? A: 200-year flood protection is another way of saying there is a 1 in 200 chance of flooding in any given year. Because the Central Valley is vulnerable to large flood events, the legislature passed the Central Valley Flood Protection Act of 2008 to provide additional protection to the region.
Q: Why does it matter? A: Millions of Central Valley residents live and work in high-risk flood zones. Courts have ruled that our government could be liable for billions of dollars in damages if a major flood damages private property, not to mention the cost of repairing levees, roads, and the state’s water transport system. Flooding could even impact the delivery of drinking water to over 25 million Californians from San Diego to Redding. Every Californian has a stake in reducing flood risk in the Central Valley.

American Water Resources Association (AWRA): “Climate Change Adaptation” June 15 – 17, 2015 in New Orleans, Louisiana
Abstracts due to AWRA website: 02/13/2015
The focus of the conference is on ACTION – how we more effectively develop and use climate change adaptation information to respond, build resilient systems, and influence decision makers. The conference will bring water professionals from federal, state, local, and private sectors together to focus on the issues that need to be addressed to develop effective strategies for mitigating climate change impacts such as sea-level rise, changes in precipitation patterns, increased severe weather events, and worsening droughts, AND more effectively communicate such information to decision makers. Conference sessions will be devoted to addressing the following questions:
• How can climate change adaptation be integrated into water, coastline, and riparian resource planning and management?
• How can data, models and tools aid in adaptive actions?
• What are social/cultural factors of climate change adaptation?
• How are businesses and economics impacted by climate change and can they serve as drivers of action?
• What adaptation actions should be taken to conserve, restore, protect, and enhance water quality and quantity?
• Moving from planning to action – what steps are needed? What do decision makers need?
• What engineering and infrastructural approaches are available to address climate change adaptation?

WASHINGTON, Feb. 23, 2015 – Agriculture Secretary Tom Vilsack today announced $20 million is being made available to improve wildlife habitat and enhance public access for recreational opportunities on privately held and operated farm, ranch and forest lands. Funding is available to state and tribal governments through the Voluntary Public Access and Habitat Incentive Program (VPA-HIP), authorized in the 2014 Farm Bill… Today’s announcement marks the second funding round. The first round of funding under the NRCS-administered VPA-HIP occurred in fiscal year 2014. USDA provided $20 million for access to approximately 2.5 million acres in nine states and one tribal nation and to help state and tribal governments advance recreational opportunities through wildlife habitat and public access improvements on private lands. More information on the fiscal year 2014 grantees can be viewed at VPA-HIP 2014 Funding Grantees. For more information, see the notice on Grants.gov or the NRCS VPA-HIP website.
The IWJV Capacity Grants Program is intended to build capacity and catalyze partnerships that measurably contribute to the protection, restoration, or enhancement of priority bird habitats to support sustainable populations of birds in the Intermountain West. Successful capacity grants are meant to join conservation partners together—around priority areas, habitats, or bird species—to improve conservation program effectiveness.

With California facing one of the worst droughts on the books and new restrictions imposed statewide by the state water board, a lot of us have been thinking about what each of us can do to cut back on water use.
How much water do you really save by shaving a couple minutes off your showers each day? And what happens when you start including the “water footprint” of products you buy and use every day? It takes about 170 gallons of water to grow one pound of wheat, for instance. So that bone-dry toast you slather with butter in the morning has hidden water costs. So does the butter, for that matter. We put together a quiz to see if you can figure out which products or routines consume the most water. Keep in mind the figures can vary pretty broadly depending on how the calculations are made and your individual situation. Either way, we hope you discover some new ways to help save water during this “epic drought.”
