Focus of the Week– Global Groundwater Crisis
Sustained drought in California is depleting aquifers (click to enlarge).
by Joe Romm Posted on October 31, 2014 at 1:22 pm
An alarming satellite-based analysis from NASA finds that the world is depleting groundwater — the water stored unground in soil and aquifers — at an unprecedented rate. A new Nature Climate Change piece, “The global groundwater crisis,” by James Famiglietti, a leading hydrologist at the NASA Jet Propulsion Laboratory, warns that “most of the major aquifers in the world’s arid and semi-arid zones, that is, in the dry parts of the world that rely most heavily on groundwater, are experiencing rapid rates of groundwater depletion.”
The groundwater at some of the world’s largest aquifers — in the U.S. High Plains, California’s Central Valley, China, India, and elsewhere — is being pumped out “at far greater rates than it can be naturally replenished.” The most worrisome fact: “nearly all of these underlie the word’s great agricultural regions and are primarily responsible for their high productivity.” And this is doubly concerning in our age of unrestricted carbon pollution because it is precisely these semiarid regions that are projected to see drops in precipitation and/or soil moisture, which will sharply boost the chances of civilization-threatening megadroughts and Dust-Bowlification.
As these increasingly drought-prone global bread-baskets lose their easily accessible ground-water too, we end up with a death spiral: “Moreover, because the natural human response to drought is to pump more groundwater continued groundwater depletion will very likely accelerate mid-latitude drying, a problem that will be exacerbated by significant population growth in the same regions.”
So this is very much a crisis, albeit an under-reported one. But why is NASA the one sounding the alarm? How has the space agency been able to study what happens underground? The answer is that NASA’s Gravity Recovery and Climate Experiment (GRACE) satellite mission can track the earth’s mass over space and time — and large changes in the amount of water stored underground cause an observable change in mass.
Here is California’s groundwater depletion over the last three years as observed by GRACE:
NASA: “The ongoing California drought is evident in these maps of dry season (Sept–Nov) total water storage anomalies (in millimeter equivalent water height; anomalies with respect to 2005–2010). California’s Sacramento and San Joaquin river basins have lost roughly 15 km3 of total water per year since 2011 — more water than all 38 million Californians use for domestic and municipal supplies annually — over half of which is due to groundwater pumping in the Central Valley.”
Certainly, the combined threat of mega-drought and groundwater depletion in the U.S. breadbaskets should be cause for concern and action by itself. But we should also worry about what is happening around the globe, if for no other reason than it inevitably affects our security. As I wrote last year, “Warming-Fueled Drought Helped Spark Syria’s Civil War. Dr. Famiglietti explains the risk: Further declines in groundwater availability may well trigger more civil uprising and international violent conflict in the already water-stressed regions of the world, and new conflict in others. From North Africa to the Middle East to South Asia, regions where it is already common to drill over 2 km [kilometers] to reach groundwater, it is highly likely that disappearing groundwater could act as a flashpoint for conflict.
Outside of this country, NASA has observed aquifer declines in “the North China Plain, Australia’s Canning Basin, the Northwest Sahara Aquifer System, the Guarani Aquifer in South America … and the aquifers beneath northwestern India and the Middle East.”
Water storage declines (mm equivalent water height) in several of the world’s major aquifers.
Famiglietti says that groundwater “acts as the key strategic reserve in times of drought, in particular during prolonged events,” such as we’re seeing in the West, Brazil, and Australia: Like money in the bank, groundwater sustains societies through the lean times of little incoming rain and snow. Hence, without a sustainable groundwater reserve, global water security is at far greater risk than is currently recognized.
Yes, we can stave off bankruptcy a little longer despite our unsustainable lifestyle by taking money from our children’s bank accounts. As we reported last year, we’re taking $7.3 trillion a year in natural capital — arable land, potable water, livable climate, and so on — from our children without paying for it. In short, humanity has constructed the grandest of Ponzi schemes, whereby current generations have figured out how to live off the wealth of future generations.

Unable to fly, nestling birds depend on their parents for both food and protection: vocal communication between parents and offspring helps young birds to determine when they should beg for food and when they should crouch in the nest to avoid a predator seeking an easy meal. A group of researchers has found that ambient, anthropomorphic noise — from traffic, construction and other human activities — can break this vital communications link, leaving nestlings vulnerable or hungry….
Green Spaces Don’t Ensure Biodiversity in Urban Areas

The lengths we go to for love can sometimes be dramatic—and so it is for male great bustards (Otis tarda), whose daredevil diet of poisonous beetles may actually help them get a date, a new study reveals. Scientists already knew the large birds, which are native to parts of Europe and Asia, snack on toxic insects to clear their guts of certain intestinal parasites, including bacteria, nematodes, and tapeworms. But the new research, published this week in PLOS ONE, shows that males eat substantially more blister beetles than females, a strategy that makes them appear healthy—and thus sexier—during courtship rituals. If true, the findings may be the first known case of a male “self-medicating” to attract females, according to the study authors.

Bioluminescent algae on Florida’s East Coast are part of increasing numbers of algae blooms in the U.S. — some of which are toxic, with possible impacts including tainted drinking water and poisoned shellfish beds. (Florida Today Communications/PR Newswire)
COCOA, Fla. — Karen McLaughlin normally carries a flashlight for her nighttime kayak trips along Florida’s Banana River to spot any alligators resting on the banks. But these days, it’s the river itself that glows in the dark. “It’s beautiful!” McLaughlin, an eco-tour guide, said as her boat’s wake set off an eerie light show on a moonless October night. Each dip of her paddle stirred up bioluminescent plankton that have invaded this eastern Florida waterway in record numbers since late summer. Like millions of tiny fireflies, they lit a jumping fish in a geyser of emerald light. A manatee out for the evening glowed like an alien spaceship as it passed underneath. It was striking, but also strange: In a region where explosive “blooms” of toxic or nuisance algae have battered fisheries and killed dolphins and sea turtles in recent years, the glowing microorganisms represent another mysterious shift in an ecosystem that scientists say is out of kilter… In the same week that some Florida researchers monitored the bioluminescent algae on Florida’s East Coast, others were keeping watch on remnants of a massive “red tide” in the Gulf of Mexico, a swath of toxic algae that at one point stretched 100 miles. From Southern California’s beaches to the Chesapeake Bay, waterways across the United States are seeing increasing numbers of algae blooms, with impacts including tainted drinking water and poisoned shellfish beds. Some are linked to higher levels of nitrogen pollution from livestock waste and fertilizers from suburban lawns and farms. Others are mostly natural events that are occurring in new places as oceans and inland lakes grow warmer.

When they’re flying south for the winter, birds need to rest their weary wings—preferably somewhere with food and water. But due to California’s agricultural development (not to mention its record-breaking drought), their preferred West Coast wetland stopovers are few and far between. So Matt Merrifield, a geographer with the Nature Conservancy of California, dove into geospatial data to help develop an alternative. The answer: flooded rice paddies. After the September harvest, farmers flood their fields to break down leftover rice straw. That’s water—but not on the right schedule. “We had to identify, very specifically in time and space, where there were a lot of birds but not a lot of water,” Merrifield says. So he overlaid migration data—crowdsourced from birders—with satellite images showing farmland water use. Then the Conservancy paid rice growers in the overlapping areas of California’s Central Valley to keep certain fields flooded when the birds arrive in October. The result: about 10,000 acres of popup wetlands for birds to visit en route from Alaska to South America, sited underneath them at the exact time they need a landing. “Eventually we want to do this not only in the Central Valley but up and down the Pacific Flyway,” Merrifield says. That should make for some happy birds.

BOZEMAN, Mont. — FALL is the season of apples, frost, turning leaves and roadkill. A 2008 congressional study found that one in 20 reported motor vehicle collisions is animal-related, and the numbers peak in autumn. Annually, these incidents result in about 26,000 injuries and 200 human deaths. Across the country, collisions with deer — the most common type of animal-related incident — cost more than $8.3 billion per year, including vehicle repair, medical services, towing, law enforcement time and carcass disposal. The damages increase when larger animals like moose or elk are hit.
Spring and autumn, when animals are migrating, searching for mates or evading hunters, are the riskiest periods. Many animals, including deer, are active at dusk and dawn, when twilight reduces their visibility to predators — and to drivers, resulting in more collisions. The transitions to and from daylight saving time are especially hazardous because the timing of our commutes shifts overnight before animals can adjust to avoid the rush hour. This also contributes to the seasonal spike in animals killed. It’s hard to quantify the full impact of vehicle collisions on wildlife populations because most reported incidents involve larger animals like deer (and even those are underreported). The toll on smaller creatures like squirrels, salamanders and birds goes largely uncounted, but a recent study estimated that as many as 340 million birds are killed by vehicles annually. For 21 species listed by federal authorities as threatened or endangered — including the Canada lynx, the red wolf, the Florida panther, the crested caracara and Florida scrub-jay — road death is a
major threat to survival.
How can we reduce this carnage? Most collisions with animals occur on two-lane highways that have relatively low traffic volumes (fewer than 5,000 vehicles per day). With greater awareness, motorists can adapt their driving. Research shows that drivers who anticipate danger can halve their reaction time and cut the risk of collision. Roadside signs may warn us of wildlife crossing these stretches of road, but if drivers rarely encounter animals, they can become habituated to the warnings. Flashing lights augmenting these signs can slow drivers, but they’re most effective if used only during the riskiest periods. Drivers are less likely to ignore animal crossing warnings that are activated by systems that detect moving animals in real time, but these dynamic signs are relatively rare. Ultimately, any system that relies on altering driver behavior will only have limited success. Surprisingly, changing animal behavior is more promising. The most effective tactic uses fencing to channel animals toward structures that safely cross roads. Panthers and alligators in Florida travel through culverts under a section of Interstate 75 known as Alligator Alley. Grizzly bears in Canada’s Banff National Park use overpasses designed for wildlife to cross the Trans-Canada Highway. Texas is planning underpasses along Highway 100 that, when constructed, could protect our 50 remaining ocelots.
In Wyoming, pronghorn following the 6,000-year-old “Path of the Pronghorn” (our only federally protected migration corridor) are now guided by fences to overpasses and underpasses that cross a highway that lies between their summer and winter ranges. When work on the safe passages and fencing was completed in 2012, we watched the initial crossing attempts of the pronghorn in suspense. When they first encountered the guide fences, they chaotically tried to get through, unaware of the nearby overpass. In time, though, every group of pronghorn found its way over the busy highway. Their instinct to reach their winter range exceeded their fear of the unfamiliar structures; now, these are simply part of their migration path.
The value of conserving this magnificent phenomenon — one of the last intact long-distance terrestrial migrations — is, in one sense, immeasurable. But it works in monetary terms, too. Before the project, drivers risked colliding with the 140-pound horned animals that crossed the highway by the thousands during their twice-yearly migrations. Over time, the cost savings from avoided collisions will offset the initiative’s $9.7 million price tag. Based on the accident reduction rate so far, the investment will pay off in about 12 years.
Later this year, Congress must reauthorize a transportation bill that includes provisions designed to reduce animal-vehicle collisions and protect both drivers and wildlife. Congressional representatives must back clauses in the bill that would empower transportation agencies to use these engineering solutions where needed.
Drivers must do their part to avoid wildlife collisions by slowing down and paying attention when there’s a high probability of encountering wildlife. But the best way of avoiding collisions is to build highways that reduce the hazards for drivers and animals alike where the risks are highest.

Restoring wetlands can help reduce or reverse soil subsidence and reduce greenhouse gas emissions, according to research in California’s Sacramento-San Joaquin River Delta. The study is one of the first to continually measure the fluctuations of both carbon and methane as they cycle through wetlands.
The study, which is one of the first to continually measure the fluctuations of both carbon and methane as they cycle through wetlands, appears in the journal by Global Change Biology.
Worldwide, agricultural drainage of organic soils has resulted in vast soil subsidence and contributed to increased atmospheric carbon dioxide concentrations. The California Delta was drained more than a century ago for agriculture and human settlement and has since experienced subsidence rates that are among the highest in the world. It is recognized that drained agriculture in the Delta is unsustainable in the long-term. To help reverse subsidence and capture carbon, there is interest in restoring drained agricultural land-use types to flooded conditions, but flooding may increase methane emissions. Carbon dioxide is the primary greenhouse gas emitted through human activities, but pound for pound, methane’s impact on climate change is more than 20 times greater than carbon dioxide.
Researchers at Dartmouth, UC-Berkeley and UC-Davis installed monitoring equipment on three moveable four-meter towers, measuring carbon dioxide and methane concentrations above a pasture and a cornfield that had been drained and a flooded rice paddy, a newly restored wetland and a wetland that underwent restoration in 1997. They found that the drained sites were net carbon and greenhouse gas sources. Conversely, the restored wetlands were net sinks of atmospheric carbon dioxide, but they were large sources of methane emissions, says co-author Jaclyn Hatala Matthes, an assistant professor an assistant professor in Dartmouth’s Department of Geography. “However, we do expect that the methane emissions will stabilize over time,” she says. “We’ve seen that emissions tend to increase for the first few years, and that this increase is correlated with the increase in wetland plant growth and spread during this time.” In another recent paper published in the Journal of Geophysical Research-Biogeosciences, Matthes and her co-authors analyzed the correlation between wetland methane emissions and vegetation around the towers, where more plants resulted in an increase in the methane emissions. Where the vegetation patches had more “edges” — convoluted borders — the methane emissions were lower. “We are looking at the structure of vegetation patterns that might help to inform management goals for a restored wetland, how big do you want the vegetation patches to be, how much edge they should have,” Matthes says. “It’s a little bit tricky in ecosystem engineering, but we are hoping to learn some things about how people might plan wetland vegetation in order to maximize carbon dioxide uptake but to minimize methane release.”

Journal of Rangelands and Climatic Change September 30 2014
ABSTRACT: Rangelands cover large areas in the United States and across the world and are natural carbon sinks which if properly managed and maintained can sequester substantial amounts of atmospheric carbon dioxide in the form of soil organic carbon and mitigate climate change. Varied climatic conditions impact carbon sequestration at the arid and semi-arid ecological sites on rangelands. Best management practices, site-specific policies and technological options are important approaches to manage these ecosystems to mitigate the impact of current climate variations. There are a number of co-benefits associated with management of rangelands for carbon storage, these include; improve soil quality and resilience, agronomic productivity, advancing global food security and restoring ecosystem diversity. Also, the non-equilibrium model is proposed for use on these xeric sites of rangelands since it better reflects the ecological dynamics that impact carbon sequestration and as such policies should be embodied this understanding. More studies are needed on the ecological dynamics, and factors that affect soil carbon sequestration process and mechanisms on arid and semi-arid environments as well as the soil organic carbon residence time so as to better our understanding of these regions. The voluntary carbon market was a good approach for stimulating carbon sequestration on rangelands, however the causes of failure should be revisited, addressed and necessary amendment to policies made that will be the driving force towards environment restoration and conservation.
Some of the obvious challenges and opportunities with regards to efficient use of rangelands as carbon sinks to mitigate as well as adapt to climate change are discussed in this paper.

A new study has found that implementing stricter fisheries management overcame the expected detrimental effects of climate change disturbances in coral reef fisheries badly impacted by the 1997/98 El Niño, according to the Wildlife Conservation Society. The 17-year study led by WCS fisheries scientists
found that rapid implementation of fisheries restrictions countered adverse climate effects and actually increased fisheries catches, counter to predictions and findings in other studies without stricter management. This is good news for the millions of people who depend on coral reefs fisheries, as it provides a management solution for fisheries predicted to decline with global warming.

Global warming-related sea ice melt in a portion of the vast Arctic Ocean has doubled the risk of colder and snowier winters in Eurasia since 2004, a new study found. The study is the latest in a spate of recent research to examine the ties between rapid Arctic warming and the rest of the Northern Hemisphere. Much of that research is still highly contentious in the mainstream climate science community. Here is what scientists agree on:
The Arctic is warming at a rate about twice as fast as that of the rest of the globe, and this is rapidly depleting the region’s sea ice, mainly during the summer and early fall.
Rapid Arctic warming is altering the exchange of heat and moisture between the ocean and atmosphere across the Arctic.
Arctic warming may be helping to alter the broader jet stream, which is a corridor of high winds at about 35,000 feet that acts as a weather highway, blowing from west to east across the hemisphere.
The new study, published Sunday in the journal Nature Geoscience, uses 100 computer models as well as observational data to show that recent trends toward colder winters in much of Russia, China, and portions of eastern Europe may be related to the loss of sea ice in the Barents and Kara Sea…

This is a guest post from Richard P Allan, who is a professor in the Department of Meteorology at the University of Reading/UK…
It is well known that the surface has warmed over the past few decades, primarily in response to rising concentrations of greenhouse gases. ENSO variability and other natural factors, have additionally contributed toward year-to-year fluctuations about this warming trend (dark red line in Figure 1). Strong El Niño events add a few tenths of a degree Celsius to the global average surface temperatures. However, there has recently been an observed slowing in the rate of surface warming (compare the red and orange trend lines in Figure 1) which may be related in part to a greater number of cold La Niña events in the 2000s compared to previous decades (see article by Climate.gov).
Figure 1: Observed changes in global annual average surface temperature relative to 1961-1990 from the HadCRUTv4 dataset which is updated to account for gaps in data coverage (version 2.0 Long Reconstruction). The temperature difference is compared with 1961-1990 average using data from Cowtan & Way (2014). The rate of warming from 1970-2013 (red trend line) is larger than the rate of warming between 1998-2013 (orange line).
On its own, though, ENSO is only part of the story, and it cannot fully explain how and why extra heat trapped by rising greenhouse gas concentrations is unable to raise surface temperatures; recent research indicates that, if anything, the Earth is gaining heat at an increasing rate. How can warming at Earth’s surface have slowed when energy accumulation is becoming larger? The role of our oceans is central in answering this.
Where is the increasing heat coming from?
As greenhouse gas concentrations continue to rise, infra-red radiative cooling by the surface and the atmosphere (1) to space becomes less effective. This sends the planet out of balance, with more energy arriving through absorbed sunlight than leaving through infra-red radiation. Or to put simply, more energy stays on our planet than leaves, which results in the Earth warming. The heating effect is modified by knock-on effects which amplify or reduce climate change through vicious cycles or “feedbacks.” For example, as the atmosphere warms, observations and basic physics agree that the atmospheric moisture content increases. This enhances the strength of the greenhouse effect, and therefore the overall heating effect, still further. Inexorable rises in greenhouse gas concentrations have driven a radiative imbalance leading to global warming at the surface, which has been amplified by the associated increases in atmospheric moisture. These processes are crucial in explaining rapid global climate change during my lifetime.
So where is the recent surface warming?
While ENSO influences Earth’s overall heating rate and global surface temperatures from year to year (Figures 1-2), what explains the diminishing rate of surface warming over the longer period from the 1990s to the 2000s? A number of small volcanic eruptions (which make the planet reflect more sunlight) and a slightly weaker sun in the 2000s compared to the late 1990s are thought to have offset some of the heating effect of rising greenhouse gas concentrations. However, our recent analysis of satellite data, ocean measurements and detailed simulations (see Figure 2) indicates that Earth’s heating rate has not diminished over the period 1985-2012. And if anything it has increased. Currently heat is accumulating at a rate approximately equivalent to every person worldwide using 20 tea kettles each to continuously boil the oceans. That’s a big tea party….

There have been a number of studies that have come out recently on ocean warming and sea-level rise. Collectively, they are helping scientists coalesce around an emerging understanding of climate change and its impact on the Earth. Most recently, a study by scientists Sarah Purkey, Gregory Johnson, and Don Chambers was published. This team was responsible for a 2010 paper that was groundbreaking in that it quantified very deep (abyssal) sea warming. This latest paper is, in some respects, a continuation of that work. The researchers recognized that changes to the sea levels are mainly caused by thermal expansion of ocean waters as they heat, changes to the saltiness of water, and by an increase in ocean waters as ice melts and flows into the sea. The total annual sea level rise is about 3 mm per year – the question is, how much of that is from expansion and how much is from melting?…. Dr Johnson summarised their results,
We find a small but measurable contribution from deep-sea warming to the global sea level budget (and hence global energy budget) from 1996–2006. The ocean warming is estimated directly from highly accurate, full-depth, oceanographic temperature data. The magnitude of the deep warming contribution to sea level below 2,000 m is about 13% of the total contribution of the mass trend below 2,000 m for that same time period.
I asked how this paper agrees or disagrees with a recent paper that reportedly showed the deepest ocean waters are not heating. He replied that the two studies actually agree with each other. They both show that the deepest ocean waters are likely contributing only a small fraction to the overall ocean energy/water rise. On the other hand, the uncertainty is largely because the deepest waters just don’t have a history of sufficient measurements to close the uncertainty range. He also stressed the importance of a proposed fleet of deep-water measuring devices (Deep Argo).
It is sometimes said that “global warming” is really “ocean warming”. Given the importance the oceans have on our past and future climate, you can be sure scientists around the world are working to better understand how much heat is going into the oceans, where the heat is going, and what will happen in the future. The recent publications are helping us close the uncertainty range and improve our knowledge. This is what progress looks like.

Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new study published in Science, a group of Rutgers researchers have found that circulation of the ocean plays an equally important role in regulating Earth’s climate. In their study, the researchers say the major cooling of Earth and continental ice build-up in the Northern Hemisphere 2.7 million years ago coincided with a shift in the circulation of the ocean — which pulls in heat and carbon dioxide in the Atlantic and moves them through the deep ocean from north to south until it’s released in the Pacific. The ocean conveyor system, Rutgers scientists believe, changed at the same time as a major expansion in the volume of the glaciers in the northern hemisphere as well as a substantial fall in sea levels. It was the Antarctic ice, they argue, that cut off heat exchange at the ocean’s surface and forced it into deep water. They believe this caused global climate change at that time, not carbon dioxide in the atmosphere. “We argue that it was the establishment of the modern deep ocean circulation — the ocean conveyor — about 2.7 million years ago, and not a major change in carbon dioxide concentration in the atmosphere that triggered an expansion of the ice sheets in the northern hemisphere,” says Stella Woodard, lead author and a post-doctoral researcher in the Department of Marine and Coastal Sciences. Their findings, based on ocean sediment core samples between 2.5 million to 3.3 million years old, provide scientists with a deeper understanding of the mechanisms of climate change today. The study shows that changes in heat distribution between the ocean basins is important for understanding future climate change. However, scientists can’t predict precisely what effect the carbon dioxide currently being pulled into the ocean from the atmosphere will have on climate. Still, they argue that since more carbon dioxide has been released in the past 200 years than any recent period in geological history, interactions between carbon dioxide, temperature changes and precipitation, and ocean circulation will result in profound changes.

Farmland is vanishing in part because the salinity in the soil is rising as a result of climate change and other human-made phenomena. In an Opinion piece publishing in the Cell Press journal Trends in Plant Sciences, researchers propose a new concept for breeding salt- tolerant plants as a way to contribute to global efforts for sustainable food production. “We suggest that we should learn from nature and do what halophytes, or naturally salt-loving plants, are doing: taking up salt but depositing it in a safe place — external balloon-like structures called salt bladders,” says co-senior author Prof. Sergey Shabala, of the University of Tasmania, in Australia. “This strategy has never been targeted by breeders and, therefore, could add a new and very promising dimension to breeding salinity-tolerant crops.”…

Ever-increasing global warming has created a societal imperative to reach and engage youth, whose futures are at risk. In this paper, we evaluate the climate science knowledge, beliefs, attitudes, behavior and communication impact of an entertainment-education high school assembly program in a random sample of 49 schools (from population of 779 that received the intervention) and a panel of 1,241 students. Pre- and post-assembly surveys composed of questions from the Global Warming’s Six Americas segmentation and intervention-specific measures were administered in classrooms. We demonstrate that exposure to climate science in an engaging edutainment format changes youths’ knowledge, beliefs, involvement, and behavior positively and moves them to audience segments that are more engaged in the issue. The net impact of scaled, multi-sensory, captivating programs for youth could be a population shift in science-informed engagement in the issue of climate change. In addition, such programs can inspire youth for deeper engagement in school programs, personal action, and political and consumer advocacy.

These pomegranates are about an inch smaller than the typical size, but they’re packed with antioxidants.

California’s severe drought is putting stress on everyone these days: the residents whose wells are running dry; the farmers forced to experiment with growing their produce with much less water; and of course, the thirsty fruits and vegetables themselves. But preliminary research suggests the dryness isn’t hurting the produce’s nutritional value, and with a few added minerals may even boost it.
That’s the tantalizing concept Tiziana Centofanti has been studying at the U.S. Department of Agriculture lab in Parlier, Calif., a sprawling campus of experimental farmland about half an hour south of Fresno. Centofanti is a research scientist affiliated with the Center for Irrigation Technology at Fresno State. One of the questions she’s asking is how fruit trees react to drought, compared to fruit from trees that get plenty of water. “My research is about physiological response to stresses,” Centofanti says, “and drought is one of those.”….Research shows that pomegranates have specific compounds that may reduce swelling and infection, even possibly fight DNA damage and cardiovascular disease. So to see how drought might change that fruit chemistry, Centofanti takes the water-stressed pomegranates into the lab, cuts them and uses a French press to squeeze everything, including the peel, into juice. She shakes that onto a magnetic stirrer, and analyzes it with liquid chromatography.
Preliminary data, she says, confirm her suspicions about drought’s effect on the fruit’s nutritional value. “Does not affect the fruit quality, so nothing, no differences at all,” Centofanti says, gesturing toward a deep freezer full of fruit samples. Indeed, so far the results from this study show that the cracked pomegranates grown with much less water still have all the normal antioxidant levels — the same amounts of vitamin C, micronutrients and macronutrients. Same results with the drought-stressed grapes that Centofanti has tested….. As The Salt previously has reported, other farmers in California who’ve been experimenting with so-called dry farming, which involves using far less water than normal, have found it can create much sweeter, more flavorful produce. Meanwhile, researchers in Mexico, Thailand, Taiwan and Spain have managed to grow spicier peppers by giving them less water. But when UC scientists working with jalapeño growers in Santa Clara and San Benito counties tried repeating the experiment, the results were only lukewarm.

One Man Single-Handedly Plants Forest Bigger Than Central Park
He did it to save his home. In the middle of a braided river tucked in a remote northeastern region of India, one man planted a forest that has now outgrown the size of New York City’s Central Park. As a teenager in the 1970s, Jadav Payeng noticed a rush of snakes washing ashore, dead. Erosion had scrubbed away vegetation from Majuli island sandbars, stripping away grassy cover and ultimately forcing many native species to flee. Floodwaters transformed some parts into barren landscapes. Its shorelines receded with every monsoon rain. The island, Payeng’s birthplace, was rapidly shrinking.
Home to approximately 170,000 people, Majuli is one of the world’s largest river islands situated in the middle of the mighty Brahmaputra, making it vulnerable to the tides of a large number of tributaries. The river’s strength reaches an apex every spring when glacial melt from the Himalayas supercharges floodwaters. Flooding has become a problem intensified in recent years due to the effects of climate change and earthquakes, leaving the river’s shape and flow altered after seismic activity. Over the past 100 years, Majuli has lost over 70 per cent of its landmass. ……McMaster collected his footage and made an 18-minute short film in 2013 titled “Forest Man.” This summer, it won best documentary at The American Pavillion Emerging Filmmaker Showcase at Cannes.

Financing for local climate change adaptation initiatives comes from a number of sources: international and bilateral funds specifically targeting climate change, existing local, regional and national level budgetary support from governments, NGOs and INGOs working on climate change, private sector investments, philanthropic contributions, and increasingly, communities themselves who are providing finance and other in-kind contributions to improve local resilience in the face of growing climate-related challenges. There is, however, no global system for tracking and measuring the total amount of global finance made available for adaptation from all these sources. Work on the monitoring and evaluation (M&E) of adaptation and adaptation finance is a fast-evolving area, and tools and data sets are being developed, but most tracking does not look at where finance goes beyond the national level….

12 ways communities will have to adapt to handle climate change
Whatever your water crisis, whether drought or flood, these DIY solutions will help you adjust to climate change’s new reality

Climate change is making both droughts and flood more frequent and severe. Whether your area is suffering from too much water or too little, here are things you can do to adapt.
In the face of relentless droughts such as the historic one underway in California, we all want to help conserve. But with water utilities increasingly introducing tiered pricing – in which people who use more water pay an increasingly higher price for it – cutting back can reap monetary savings as well.
Replace lawns with native plants
Outdoor water use accounts for 30% of residential demand across the US, and 80% in the arid West, according to Mary Ann Dickinson, president of the Alliance for Water Efficiency. Nixing grass for drought-tolerant native plants can save as much as 10,000 gallons of water a year. Or reduce your lawn’s size and replace standard grass with low-water varieties that make do with two-thirds less water. Local native plant societies often know which plants made your lot home before you did. In the West, where most rain comes during the winter, plant natives in the fall. Natives also provide habitat for local butterflies and birds, and can be more resistant to wildfire than ornamentals.
Cut the flush
Toilets use the most water of all indoor fixtures, nearly 30% of home water use, according to the EPA. Drop-A-Brick offers an easy way to cut back. The flattened brick is filled with a powder that turns solid when it gets wet, giving it the weight needed to sink. One $15 Drop-A-Brick in a toilet’s tank will displace almost half a gallon of water per flush, saving around $25 a year on water bills. Why use a manufactured, $15 brick instead of a Lifehacker-style solution like a milk jug filled with water? It “actually improves flushing performance in most [toilets] because it causes water to accelerate more quickly through the flush valve, according to engineers,” said Ali Hart, director of toilet relations for “Project: Drop-A-Brick.” No more flushing twice to clear low-flow toilets!
“The real goal of this campaign,” she added, “is to raise awareness about urban water conservation.”
People tend to dramatically underestimate personal water use. One study found that Americans lowballed their water use by a factor of two. One reason is that we typically get one water bill every two months – a huge gap between use habits and measurement. Tech companies like WaterSmart and Dropcountr are trying to reverse this trend. Dropcountr’s mobile app allows you to track how you use water, set conservation goals, access rebates for low-flow appliances and more. It also alerts you to usage trends that may land you in a higher-priced billing tier and adds a competitive factor by tracking how well you’re keeping up (or rather down) with the Joneses.
Use rain barrels and graywater systems
Plants don’t need drinking-quality water. Connecting rain barrels to downspouts is an inexpensive way to harvest rain to supply your garden. Such on-site water supplies increase your water security, independence, and efficiency. Overachieving water conservers have long put a bucket in the shower or kitchen sink to collect “greywater” for plants outside. But an installed system delivering greywater from, say, your washing machine in the garage into your garden would be much easier. Such systems have long been illegal in many jurisdictions, but that’s beginning to change thanks in part to groups like Greywater Action.
Opt for dual plumbing
Your toilet doesn’t require drinking water, either. A dual plumbing system allows you to reroute greywater or rainwater back into your house for flushing (or use utility-delivered treated wastewater in some districts). Pipes that route non-potable water are colored purple so that everyone knows not to connect them to sinks. A diverter valve allows people to choose potable water for some needs and alternative water for the rest. If you’re buying a new house in an area where purple pipes are now in the building code, such as San Francisco, you could be on the cutting-edge of water conservation. Otherwise, save this strategy for a major remodel.
Worldwide, increasing development in floodplains is paving over soil that would otherwise soak up water. Coastal plain development is also booming, creating infrastructure that’s more vulnerable than ever as sea levels rise with climate change. A World Bank report last year found that flood damage to coastal cities worldwide could reach $1tn annually.
To avoid paying your share of that, consider the following adaptations.
Location, location, location
This may be obvious, but think before you move. Whether buying or renting, consult flood maps to see if that lovely home is at high risk. If you simply must live near a coast or river, choose or build a home elevated to a height above your area’s predicted flood level rise.
Raise the mechanicals and valuables
Move vulnerable elements like furnaces, water heaters and electric panels to higher ground when building or remodeling. If you have a basement, don’t keep a giant plasma TV, gaming center or collection of antiquarian books down there.
If flooded, put government emergency grants or insurance payouts toward moving to higher ground, not rebuilding. Some cities that flood regularly have used such funds to buy out willing homeowners and transform floodplains into open space. If your city doesn’t offer this option, introduce it at planning meetings. After Tulsa, Oklahoma, bought and removed more than 800 flood-damaged homes and vulnerable buildings and turned the floodplain into a park, flood insurance rates dropped 25%.
Plan for soft failure
If you’re already living in a flood zone, you can make your home resilient via renovations that minimize the effect of floodwater. Choose flood damage-resistant materials such as glazed brick, concrete, stone, steel or recycled plastic lumber. Anchor the foundation to resist flotation, collapse, or lateral movement. Create “flow-through” features on the lower levels to prevent water pressure damage.
Use rain gardens and low-impact development
Permeable surfaces are your friends. Rather than paving your driveway, choose materials such as pavers that allow water to seep through them into the ground, or gravel. Consider your lot’s slope. Water should flow away from your home, not toward it. Creating a rain garden will slow runoff and allow more absorption into the ground. Add slopes that funnel water into a bioswale (a fancy name for a ditch covered in stones or native grasses), toward planting spaces or a nearby creek, or even into an underground storage catchment that can hold water for drier times, or allow water to seep slowly into the aquifer. If you’re a city-dweller with pavement right up to your house, investigate a permit to dig up part of the sidewalk and plant a small garden that will convey water underground.
Apps are not just for the drought-afflicted. Using real-time data from the US Geological Survey and National Weather Service, FloodWatch gives both recent and historical river heights, precipitation totals, and flood stage data throughout the United States. The app allows you to monitor nearby rivers and streams and keep an eye on potential flooding issues, giving you time to move valuables to safety. For worldwide information check out the Flood App from Swiss Re, the leading global reinsurer. With a focus on climate change adaptation, the app offers reliable if general information on flood risks and how to manage and insure these risks.
Get flood insurance
Floods are the most common natural disaster. But flood losses are often not covered under standard renter or homeowner’s insurance policies. The good news is that often you can purchase flood-specific insurance. However, some firms are leaving flood-prone areas, reasoning it’s bad business to continue insuring such risky properties. If that’s the case where you live, consider it a sign that you should move. In the United States, the National Flood Insurance Program (NFIP), administered by Fema, provides federally subsidized plans in locales that agree to implement its floodplain management ordinances. Homeowners, business owners, and renters in participating areas can purchase these plans via www.FloodSmart.gov.

A plan to steeply cut greenhouse gas emissions is an important step forward and a signal to other nations to set some aggressive goals of their own.
Governments and scientists have been meeting in the Danish capital Copenhagen this week to adopt a key IPCC report on the state of the climate. It says policymakers must act now to avert the worst.
October 31, 2014
Climate change may have “severe, pervasive and irreversible impacts for people and ecosystems.” But there is still time to prevent the worst by reducing greenhouse gas emissions now. That is the message from a report by the UN Intergovernmental Panel on Climate Change (IPCC) to be published on November 2 after a week of international scrutiny. The “Synthesis Report” does not contain new information. Its wording, however, lends new urgency to the issue. It integrates and condenses the information contained in three separate reports released over the past year, looking at the scientific evidence for climate change, its impacts and what can be done about it. Delegates from more than 100 governments and top scientists are attending the meeting to prepare the publication of the report and the all-important “Summary for Policymakers,” which will be essential reading for governments preparing for this year’s UN climate conference in Peru in December. The IPCC summary states clearly that global warming is happening, that humans have caused it, that it is already dangerous, and that the warming trend could be irreversible.
It makes it clear that urgent emissions reductions are required in the very near future to keep warming below two degrees Celsius to avert the worst impacts of climate change. These include extreme weather, rising sea levels, and increased heat waves, flooding and droughts. The report also suggests climate change could aggravate violent conflicts and refugee problems and have a negative effect on food production. Another major impact mentioned is ocean acidification, as the sea increasingly absorbs more carbon. This is harmful to marine life. If there are no changes to our emissions of greenhouse gas emissions, “climate change risks are likely to be high or very high by the end of the 21st century,” according to the report….

Policy options for climate change risk management are straightforward and have well understood strengths and weaknesses, according to a new study.
A growing number of electric car drivers are fueling their vehicles with the power of the sun. Rooftop solar panels can easily generate enough electricity to power an electric or plug-in gas-electric hybrid vehicle.
By Dee-Ann Durbin, Associated Press October 28, 2014 DETROIT — Owners of electric vehicles have already gone gas-free. Now, a growing number are powering their cars with sunlight.
Solar panels installed on the roof of a home or garage can easily generate enough electricity to power an electric or plug-in gas-electric hybrid vehicle. The panels aren’t cheap, and neither are the cars. A Ford Fusion Energi plug-in sedan, for example, is $7,200 more than an equivalent gas-powered Fusion even after a $4,007 federal tax credit. But advocates say the investment pays off over time and is worth it for the thrill of fossil fuel-free driving….

Solar and wind power get all the attention these days, but the global hydropower frenzy that’s currently underway could end up being just as consequential for the planet — for better or for worse. Hydropower can provide a source of renewable energy — but also wreak havoc on river habitats Hydroelectric dams are still the biggest source of renewable energy around, generating 16 percent of the world’s electricity. And, according to a recent study in Aquatic Sciences, more than 620 large hydroelectric dams are now under construction, largely in Latin America and Asia — with thousands more in various stages of planning. At the high end, if most of the planned dams were built, global hydropower production could double to 1,700 gigawatts, the study’s authors predict. This would also reduce the number of large free-flowing rivers on the planet by another 20 percent. There are upsides and downsides here. If built, these dams could provide electricity for millions of poor people who don’t have it. But dams can also be extremely controversial. Some projects can end up displacing thousands of people and destroying river habitats — something the United States learned the hard way last century. What’s more, recent research has questioned whether hydropower is always as climate-friendly as once thought…..
And what about global warming? In theory, hydroelectric dams should produce fewer greenhouse-gas emissions than, say, coal plants. But there’s a huge caveat here. Some recent research has suggested that decaying vegetation in stagnant dam reservoirs may end up producing lots of methane, another potent greenhouse gas. For many dams, this can actually offset a big chunk of the climate benefits, especially in tropical countries like Brazil. So hydropower isn’t always as green as it seems. (There are, however, ways to build lower-emitting dams — but it has to actually get done.)….
Obviously no one’s going to tear down the Hoover Dam, which still provides electricity for millions of people in Nevada, Arizona, and California. But many smaller dams are now getting dismantled — including the 108-foot Elwha River dam. (The hunt for carbon-free electricity, however, has complicated this task. Back in 2013, Congress passed a bill to help eke out more power from small rivers and streams, particularly by adding generating capacity to existing dams.) … Among other things, the US was providing aid to Cambodia to study how dam construction would affect the river’s flow. The latest Aquatic Sciences paper, by providing a comprehensive database of the 3,700 largest dams being contemplated, aims to provide a useful resources to planners hoping to address some of these concerns. “Clearly,” the authors note, “there is an urgent need to evaluate and to mitigate the social, economic, and ecological ramifications of the current boom in global dam construction.”

Ships will bring your iPhone from China—and a whole lot of “black carbon” too.

If you’ve recently purchased a new iPhone, or a fancy t-shirt, or a children’s toy… or really virtually any consumer or industrial good, there’s a strong chance that a giant ship ferried it from or through China. China, dubbed “the world’s factory” for pumping out so much of the world’s consumables, now boasts seven of the world’s top ten busiest trading ports. Strung up and down its densely populated eastern coast, China’s ten biggest ports handle nearly 30 percent of the world’s containers each year. These mega-ports—Shanghai’s is the planet’s busiest—helped China become the biggest trader in the world, eclipsing the US in 2012. China has also become the world’s second largest consumer market—meaning that more and more ships are unloading wares in the country’s ports, not just loading up. But there’s a big downside for the planet in all that trade, according to a report released Tuesday by the Natural Resources Defense Council (NRDC), a US-based environmental advocacy group with offices in Beijing. When the country’s brutal smog and worsening air crisis make international headlines, as it did earlier this month after runners in the Beijing marathon donned air masks, coal burning and China’s grid-locked streets get most of the attention. But emissions from China’s vast shipping industry have so far been “very much overlooked” by Chinese leaders, says Barbara Finamore, an author of the report and NRDC’s Asia director….

A category of lipids known as sphingolipids may be an important link in the relationship between diet, inflammation and cancer, a team of scientists has found. They have provided evidence that a sphingolipid metabolite called sphingosine-1-phosphate (S1P) found in both mammalian food products and generated by normal human cells can contribute to inflammation of the colon, inflammatory bowel disease (IBD) and inflammation-associated colon cancer, whereas soy and plant-type sphingolipids called sphingadienes may protect against these conditions.
