Abrupt Impacts of Climate Change: Anticipating Surprises (2013)
National Academy of Sciences
Authors: Committee on Understanding and Monitoring Abrupt Climate Change and Its Impacts; Board on Atmospheric Sciences and Climate; Division on Earth and Life Studies; National Research Council
Climate is changing, forced out of the range of the past million years by levels of carbon dioxide and other greenhouse gases not seen in the Earth’s atmosphere for a very, very long time. Lacking action by the world’s nations, it is clear that the planet will be warmer, sea level will rise, and patterns of rainfall will change. But the future is also partly uncertain — there is considerable uncertainty about how we will arrive at that different climate. Will the changes be gradual, allowing natural systems and societal infrastructure to adjust in a timely fashion? Or will some of the changes be more abrupt, crossing some threshold or “tipping point” to change so fast that the time between when a problem is recognized and when action is required shrinks to the point where orderly adaptation is not possible?
Abrupt Impacts of Climate Change is an updated look at the issue of abrupt climate change and its potential impacts. This study differs from previous treatments of abrupt changes by focusing on abrupt climate changes and also abrupt climate impacts that have the potential to severely affect the physical climate system, natural systems, or human systems, often affecting multiple interconnected areas of concern. The primary timescale of concern is years to decades. A key characteristic of these changes is that they can come faster than expected, planned, or budgeted for, forcing more reactive, rather than proactive, modes of behavior.
Abrupt Impacts of Climate Change summarizes the state of our knowledge about potential abrupt changes and abrupt climate impacts and categorizes changes that are already occurring, have a high probability of occurrence, or are unlikely to occur. Because of the substantial risks to society and nature posed by abrupt changes, this report recommends the development of an Abrupt Change Early Warning System that would allow for the prediction and possible mitigation of such changes before their societal impacts are severe. Identifying key vulnerabilities can help guide efforts to increase resiliency and avoid large damages from abrupt change in the climate system, or in abrupt impacts of gradual changes in the climate system, and facilitate more informed decisions on the proper balance between mitigation and adaptation. Although there is still much to learn about abrupt climate change and abrupt climate impacts, to willfully ignore the threat of abrupt change could lead to more costs, loss of life, suffering, and environmental degradation. Abrupt Impacts of Climate Change makes the case that the time is here to be serious about the threat of tipping points so as to better anticipate and prepare ourselves for the inevitable surprises.
Tipping points: Where may abrupt impacts from climate change occur?
(December 3, 2013) ScienceDaily — Climate change has increased concern over possible large and rapid changes in the physical climate system, which includes Earth’s atmosphere, land surfaces, and oceans. Some of these changes could occur within a few decades or even years, leaving little time for society and ecosystems to adapt. A new report from the National Research Council extends this idea of abrupt climate change, stating that even steady, gradual change in the physical climate system can have abrupt impacts elsewhere — in human infrastructure and ecosystems for example — if critical thresholds are crossed.
The report calls for the development of an early warning system that could help society better anticipate sudden changes and emerging impacts. …
Further scientific research and enhanced monitoring of the climate, ecosystems, and social systems may be able to provide information that a tipping point is imminent, allowing time for adaptation or possibly mitigation, or that a tipping point has recently occurred, the report says. “Right now we don’t know what many of these thresholds are,” White said. “But with better information, we will be able to anticipate some major changes before they occur and help reduce the potential consequences.” The report identifies several research needs, such as identifying keystone species whose population decline due to an abrupt change would have cascading effects on ecosystems and ultimately on human provisions such as food supply.
If society hopes to anticipate tipping points in natural and human systems, an early warning system for abrupt changes needs to be developed, the report says. An effective system would need to include careful and vigilant monitoring, taking advantage of existing land and satellite systems and modifying them if necessary, or designing and implementing new systems when feasible. It would also need to be flexible and adaptive, regularly conducting and alternating between data collection, model testing and improvement, and model predictions that suggest future data needs.

An expert panel at the National Academy of Sciences is to alert us to abrupt and potentially catastrophic events triggered by climate change. The committee says science can anticipate some major changes to the Earth that could affect everything from agriculture to sea level. But we aren’t doing enough to look for those changes and anticipate their impacts. And this is not a matter for some distant future. The Earth is already experiencing both gradual and abrupt climate change. The air is warming up slowly, and we’re also seeing rapid changes such as the melting Arctic ice cap.
….”When you think about gradual changes you can kind of see where the road is and know where you’re going,” Barnosky said at a news conference unveiling the report Tuesday. “When you think about abrupt changes and threshold effects, the road suddenly drops out from under you. And it’s those kinds of things we’re suggesting we need to anticipate in a much more comprehensive way.”
Scientists know about some potential problems that could change the planet dramatically in a matter of years or decades. For example, sea level could quickly rise by as much as 25 feet if the West Antarctic Ice Sheet were to crumble into the sea. Yet committee chairman James White, an earth scientist at the University of Colorado in Boulder, says we’re not watching that ice sheet very carefully to measure how much warming seawater is weakening the ice. “We should be measuring ocean temperatures near the ice sheet,” White said. “We should be measuring, far better, where the outlets are — where the glaciers go into the ocean. We don’t do that.”
Another potential for disaster is in the Arctic. There is a huge amount of methane gas up there. The report says the region is unlikely to belch methane into the atmosphere rapidly and supercharge global warming. But government agencies aren’t keeping a close eye on methane and other greenhouse gases in the Arctic…. We know there needs to be monitoring capability,” White said. “We know we need to be watching the planet. We watch our streets, we watch our banks — if you live in the U.K. they watch everything — we watch other parts of the system very well. “But we do not watch our environment with nearly the same amount of care and zeal.” The committee didn’t just consider abrupt changes to the planet. It also looked at gradual changes that could trigger rapid disruptions for us. For example, parts of the Earth could quickly become inhospitable to crops like corn, once the temperature creeps past a certain threshold. Those concerns are greatest in the tropics and subtropics. “Probably the biggest issues are going to show up in the warm places, even though it will be easier to see them, and we will meet them sooner, in the Arctic,” says , a glaciologist at Penn State…..

Hard-to-predict sudden changes to Earth’s environment are more worrisome than climate change’s bigger but more gradual impacts, a panel of scientists advising the federal government concluded Tuesday. The 200-page report by the National Academy of Sciences looked at warming problems that can occur in years instead of centuries. The report repeatedly warns of potential “tipping points” where the climate passes thresholds, beyond which “major and rapid changes occur.” And some of these quick changes are happening now, said study chairman James White of the University of Colorado.
The report says abrupt changes like melting ice in the Arctic Ocean and mass species extinctions have already started and are worse than predicted. It says thousands of species are changing their ranges, seasonal patterns or in some cases are going extinct because of human-caused climate change. Species in danger include some coral; pika, a rabbitlike creature; the Hawaiian silversword plant and polar bears. At the bottom of the world in Antarctica, the melting ice in the west could be more of a wild card than originally thought. If the massive ice sheet melts it may happen relatively rapidly and could raise world sea levels by 13 feet, but researchers aren’t certain how soon that may occur. However, the report had what researchers called “good news.” It said two other abrupt climate threats that worried researchers likely won’t be so sudden, giving people more time to prepare and adapt. Those two less-imminent threats are giant burps of undersea and frozen methane, a super-potent greenhouse gas, and the slowing of deep ocean currents. That slowdown is a scenario that would oddly lead to dramatic coastal cooling and was featured in the 2004 movie “The Day After Tomorrow.” Study co-author Richard Alley of Pennsylvania State University compared the threat of abrupt climate change effects to the random danger of drunk drivers. “You can’t see it coming, so you can’t prepare for it. The faster it is, the less you see it coming, the more it costs,” Alley told The Associated Press. “If you see the drunk driver coming, you can get out of the way.” The scientists said the issue of sudden changes is full of uncertainties, so the world can better prepare by monitoring places like Antarctic and Greenland ice sheets more. But because of budget cuts and aging satellites, researchers have fewer measurements of these crucial indicators than they did a few years ago and will have even fewer in upcoming years, study co-author Steven Wofsy of Harvard University said. The panel called on the government to create an early warning system….

The findings laid out below reinforce the reality that the biggest impacts of greenhouse-driven global warming still lie several generations in the future.
Evolution can select for evolvability, biologists find
(November 14, 2013) — Evolution does not have foresight. But organisms with a greater capacity to evolve may fare better in changing environments. This raises the question: Does evolution favor characteristics that increase a species’ ability to evolve? For several years, biologists have attempted to provide evidence that natural selection has acted on evolvability. Now a new article offers clear evidence that the answer is yes. … > full story

A threatened population of steelhead in Bridge Creek, Oregon is limited by degraded stream conditions (Pollock et al. 2012). By reconnecting portions of this incised channel with its former floodplain, we hoped to improve habitat conditions for steelhead. Restoring connections between a channelized stream and its floodplain can increase habitat complexity in both the stream and its associated riparian zone (Pollock et al. 2007). However, conventional stream restoration techniques can be disruptive and quite costly. Large volumes of fill must be moved and graded with heavy equipment, exposing large areas of bare ground that require extensive re–vegetation effort (Pollock et al. 2012). After it was breached by high flows, beaver abandoned this dam (foreground). They rebuilt it within 1 year of reinforcement. An additional dam built on a post line is shown upstream.
In 2009, we began a study to restore channelized streams by encouraging a local beaver population to build longer–lived dams (Pollock et al. 2012). Bridge Creek is a 710–km² watershed draining northwesterly into the lower John Day River. At present, its beaver population is small, with growth impeded by short–lived dams. Bridge Creek beaver dams are often short lived because they are built within an incised trench (Pollock et al. 2012). This means that when annual flooding occurs, pressure from heavy flows is concentrated on the dam rather than dissipated across the floodplain. Consequently, most beaver dams breach and fail within their first season. We predicted that stable beaver colonies would gradually aggrade the incised reaches of Bridge Creek enough to raise the alluvial water table and reconnect the stream to its former floodplain. Therefore, encouraging long–lived beaver dams would be a cost–effective method to produce measurable improvement in riparian and stream habitats, and subsequently in abundance of native steelhead. Our objective is to help beaver build dams that will last long enough to lead to the establishment of stable colonies. If this can be accomplished, the beaver dams should promote enough aggradation to reverse channel incision. Such a reversal would yield a number of ecosystem improvements for steelhead and other species. ….

Five distinct humpback whale populations identified in North Pacific
(December 4, 2013) — The first comprehensive genetic study of humpback whale populations in the North Pacific Ocean has identified five distinct populations — at the same time a proposal to designate North Pacific humpbacks as a single “distinct population segment” is being considered under the Endangered Species Act. …The scientists examined nearly 2,200 tissue biopsy samples collected from humpback whales in 10 feeding regions and eight winter breeding regions during a three-year international study, known as SPLASH (Structure of Populations, Levels of Abundance and Status of Humpbacks). They used sequences of maternally inherited mitochondrial DNA and “microsatellite genotypes,” or DNA profiles, to both describe the genetic differences and outline migratory connections between both breeding and feeding grounds. “Though humpback whales are found in all oceans of the world, the North Pacific humpback whales should probably be considered a sub-species at an ocean-basin level — based on genetic isolation of these populations on an evolutionary time scale,” said Scott Baker, associate director of the Marine Mammal Institute at Oregon State University’s Hatfield Marine Science Center and lead author on the paper. “Within this North Pacific sub-species, however, our results support the recognition of multiple distinct populations,” Baker added. “They differ based on geographic distribution and with genetic differentiations as well, and they have strong fidelity to their own breeding and feeding areas.” Humpback whales are listed as endangered in the United States under the Endangered Species Act, but had recently been downlisted by the International Union for the Conservation of Nature (IUCN) on a global level. However, two population segments recently were added as endangered by the IUCN — one in the Sea of Arabia, the other in Oceania — and it is likely that one or more of the newly identified populations in the North Pacific may be considered endangered, Baker said. How management authorities respond to the study identifying the distinct North Pacific humpback populations remains to be seen, Baker said, but the situation “underscores the complexity of studying and managing marine mammals on a global scale.” … > full story

Tracking marine food sources
(December 3, 2013) — Scientists have developed a method to determine where animals obtain essential amino acids. They discovered that all life forms leave traces or ‘fingerprints’ in amino acids during biosynthesis. With these fingerprints, which are based on naturally occurring isotope variations, it is possible for the first time to distinguish between algal, bacterial, fungal and plant origins of amino acids through tissue samples. This discovery makes it possible to find out what animals have been feeding on without observing them directly or examining their stomach content. … > full story

Cyanobacteria – known as the “cockroaches” of aquatic environments – have been around for more than 2 billion years. Over their long evolutionary history, they have learned to tolerate many extreme conditions and are one of the toughest microorganisms on Earth. Cyanobacteria are also largely responsible for creating the oxygen-rich conditions that stimulated modern life. But the bacteria, known for their blooms, have become quite a problem in the 21st century. In a research brief letter published in the October edition of Science, researchers from UNC Chapel Hill and Oregon State University describe how outbreaks of these bacteria are choking lakes and rivers across the globe – and how such outbreaks may worsen with climate change and human development….

Impacts of plant invasions become less robust over time: Invasive plants are more likely to be replaced by other ‘invasives’
(November 20, 2013) — Among the most impressive ecological findings of the past 25 years is the ability of invasive plants to radically change ecosystem function. Yet few if any studies have examined whether ecosystem impacts of invasions persist over time, and what that means for plant communities and ecosystem restoration. … “We were able to take advantage of detailed studies I and others had conducted in the 1990s. We permanently marked sites we had set up and were able to go back and gain insight into how plant invasions changed over time without management,” said D’Antonio, who also is a professor in the Department of Ecology, Evolution and Marine Biology. “Such studies are important because managers have little money to control invasive species or to study how impacts might change without management.” “Non-native plants can have very large impacts on ecosystem functioning — including altering groundwater, soil salinity or pH and pollination syndromes,” said lead author Yelenik, who earned her doctorate from UCSB’s Department of Ecology, Evolution and Marine Biology and now works for the U.S. Geological Survey’s Pacific Island Ecosystems Research Center on the island of Hawaii. When D’Antonio and Yelenik revisited the study sites, they noticed that the invasive exotic perennial grasses (primarily an African invader called Melinis minutiflora) were dying, so they decided to repeat measures of nutrient cycling and plant community change. They found that the grasses’ self-reinforcing effects on soil nutrients had disappeared and the percentage of invader coverage had declined…..An important lesson here is that even if plant invasions can slow down on their own given enough time, native species may need further assistance in order to make a comeback, the researchers said. Other invaders may be poised to take advantage of reduced competition from the original invader. “Knowing the mechanisms of how and why invasions alter ecosystems is insightful for predicting what will happen, but without further management we may not get native species back,” Yelenik said. “When we see non-native species dying back and getting patchy, that may be the time to plant native species. It might turn out to be the most cost-effective way to get an ecosystem back to a more desirable state.”…> full story

The world is watching the ongoing negotiations with Iran over its nuclear program. They began days after tens of thousands of Iranian demonstrators screamed “Death to America!” as they remonstrated outside the former United States embassy in Tehran. That’s what the world knows of Iran — its nuclear program, the resultant economic sanctions and the nation’s turbulent relations with the West. The Iranian government talks about little else. Neither does the Western news media. In the background, however, a far more serious problem afflicts the nation that almost no one of influence in Tehran ever discusses in public. Iran is, quite literally, blowing away. Lakes and ponds are drying up. Underground aquifers that supply most of the nation’s potable water are emptying fast. More than two-thirds of the country’s land is rapidly turning to desert; just 16 percent of it remains arable. And massive dust storms sweep across the country almost daily, afflicting 23 of the nation’s 31 provinces — making it hard to breathe and killing thousands of people a year. As the Tehran Times put it, quoting Yousef Rashidi, director of Tehran’s Air Quality Control Company, “dust storms severely affect the health of citizens.” After all, massive dust storms now envelop Tehran every third day, on average, and at least 80,000 people die from strangling dust and other pollutants annually, the state’s Health Ministry reported late last month. And yet, the nation’s leaders seem never to talk about this — or do anything about it — so fixated do they remain on their nuclear program and the American “devils.” Every once in a while, though, someone does speak out, as former Agriculture Minister Issa Kalantari did in a recent Iranian newspaper article: “The main problem that threatens us” and is “more dangerous than Israel and America or political fighting” is that “the Iranian plateau is becoming uninhabitable. If the situation is not reformed, in 30 years Iran will be a ghost town.” …

The value of a marine reserve goes beyond the obvious: new research indicates that it helps ward off some of the effects of climate change.
On the face of it, the value of a marine reserve — the equivalent of a national park or wildlife preserve on land — seems obvious. The oceans are in trouble, and setting aside regions of biodiversity, where fishing is strictly limited, if not prohibited, is one of the few effective means of protecting many species at once. But politically, there is nothing simple about creating marine reserves in international waters. Recently, China and Russia succeeded in blocking, yet again, the creation of a large marine reserve in Antarctica.
New research indicates that marine reserves may have an even greater importance than scientists previously supposed. A study recently published in Nature Climate Change found that marine reserves do more than merely shelter species that live within them. By enhancing the resilience of marine communities, reserves help ward off some of the effects of climate change, including invasion by species from warmer waters. The study was based on research conducted at the Maria Island Marine Reserve, just off the coast of Tasmania. Though the reserve was only established in 1991, data on marine life there had been collected for more than 70 years. Comparing the reserve’s ecosystem with similar but unprotected waters where fishing was allowed, scientists found greater long-term and short-term stability. The overall health of the ecosystem helped create what the authors of the study called “a feedback mechanism to promote stability.” The scientists found a substantial increase in the number of large-bodied fish and much less fluctuation, year to year, in the population of smaller fish. This is a reminder of something that all too easily goes unnoticed. How species will endure the effects of global warming depends less on the individual species than the overall health of the ecosystem it belongs to. This study also suggested another essential service that marine reserves provide. By giving us a view into a relatively unaltered past — since the 1940s in the case of Maria Island — they show how healthy ecosystems function, which will be increasingly valuable as climate change disorders them.
Rapid climate changes at end of last glaciation, but with 120 year time lag
(December 4, 2013) — Regional climate changes can be very rapid. Geoscientists now report that such a rapid climate change occurred in different regions with a time difference of 120 years. Investigation in the west German Eifel region and in southern Norway demonstrated that at the end of the last glaciation about 12,240 years before present climate became warmer, first recognized in the Eifel region and 120 years later in southern Norway. Nonetheless, the warming was equally rapid in both regions. … The result of this study has some implications on the understanding of both past and future climate change. The assumption of an everywhere and always synchronously changing climate must be questioned and climate models have to better consider such regional aspects….

Scientists are working to ensure that the Endangered Species Act remains effective in the face of a changing climate. A special section in the latest issue of Conservation Biology highlights their progress. Forty years ago this month the Endangered Species Act became law, and since then it has proved an effective tool for protecting species near the brink of extinction and the habitats they depend on. But the world is a very different place than it was in 1973, and federal agencies are adapting their science and management to protect endangered species against the array of threats they face today.
When the Act was written, no one was thinking about climate change. Scientists operated under the assumption that the environment varied but was not changing in any particular direction, and that the past was a good guide to the future. That is no longer the case.
How should we incorporate climate change into our decision-making under the Endangered Species Act? A special section in this month’s issue of Conservation Biology addresses this question with eight papers authored by NOAA scientists and their research partners who work on marine and aquatic species.
The language of the Endangered Species Act requires us to peer into “the foreseeable future” using the “best available science.” But future conditions are not guaranteed, and a changing climate can upset established trends. Making decisions under these conditions, and keeping up with emerging science, is a fundamental challenge when protecting endangered species. The eight research papers aim to help with that. “We identify lessons learned and try to provide some tools for when scientists decide if a species is at serious risk, develop recovery plans, and identify critical habitat,” said Michelle McClure, the NOAA Fisheries biologist who led the team of scientists contributing to this special section of the journal. Scientists have incorporated climate change modeling into several recent decisions on threatened and endangered species. Among them is the bearded seal, an Arctic species recently listed as threatened whose sea ice habitat is expected to shrink in coming decades. Another example is the 68 species of coral that are collectively under review for listing under the Act. Their future is threatened by, among other things, warming-induced bleaching and ocean acidification. “Climate change is just one more impact that you have to evaluate on top of all the other impacts that we have on endangered species,” McClure said, “But it’s bigger, it’s less fixable, and it’s more pervasive, so we have to be creative in our approach.”…

Humanity is choosing to destroy a livable climate, warn 18 of the world’s leading climate experts in a new study. Led by James Hansen, they make the strongest case to date for a target of 350 parts per million (ppm) of CO2 in the air, or about 1°C (1.8°F) total warming…..Humanity is choosing to destroy a livable climate, warn 18 of the world’s leading climate experts in a new study. Led by James Hansen, they make the strongest case to date for a target of 350 parts per million (ppm) of CO2 in the air, or about 1°C (1.8°F) total warming.
Yes, we are already near 400 ppm (and rising 2 ppm a year), and have warmed more than 0.8°C since preindustrial times, so the authors understand the challenge. But in their must-read article in the journal PLOS One, the scientists argue that “aiming for the 2°C [3.6°F pathway would be foolhardy” because it “would have consequences that can be described as disastrous”: … sea level rise of several meters could be expected. Increased climate extremes, already apparent at 0.8°C warming, would be more severe. Coral reefs and associated species, already stressed with current conditions, would be decimated by increased acidification, temperature and sea level rise. More generally, humanity and nature, the modern world as we know it, is adapted to the Holocene climate that has existed more than 10,000 years.
They point that even a modest temperature rise will end the stable climate that enabled modern civilization is clear in this figure derived from another recent study:
A key point of the new study — bluntly titled “Assessing ‘Dangerous Climate Change’: Required Reduction of Carbon Emissions to Protect Young People, Future Generations and Nature” — is that 2°C warming is unlikely to be stable because it “would spur ‘slow’ feedbacks and eventual warming of 3–4°C with disastrous consequences.” As Climate Progress has previously reported, the thawing permafrost alone is projected to add as much as 1.5°F (!) to total global warming by 2100 and ocean acidification could add another 0.9°F. ….
Wetland and Seagrass Restoration One Step Closer to Receiving Offsets December 5, 2013
Today, Restore America’s Estuaries submitted “Greenhouse Gas Accounting Methods for Tidal Wetland and Seagrass Restoration” to the Verified Carbon Standard to begin the approval process. This ground-breaking methodology opens the door for all tidal wetland and seagrass restoration projects that meet the eligibility conditions to calculate net greenhouse gas benefits and receive carbon credits. “This global methodology sets the stage to connect coastal restoration and carbon finance. We expect it will stimulate coastal wetlands carbon projects around the world, from mangroves and seagrass of the Coral Triangle to rebuilding tidal marshes here in the U.S.,” said Jeff Benoit, President of Restore America’s Estuaries. Coastal blue carbon refers to the role of coastal wetlands (tidal marshes, seagrass meadows and mangroves) in contributing to the global carbon cycle. Coastal wetlands sequester carbon dioxide from the atmosphere and store it in the form of biomass and soil carbon. Though only representing 2% of the world’s surface area they sequester 50% of the carbon that is transferred to marine soils and sediments. Coastal wetlands are under threat and represent one of the highest rates of loss for any ecosystem globally. At current rates, within 100 years most of the world’s coastal wetlands will be lost. In the United States losses are increasing as well. Restoration of coastal ecosystems brings benefits that support the livelihood of local communities, improve fisheries, reduce risk of flooding, provide future climate change adaptation benefits, and reverse ongoing greenhouse gas emissions from converted wetlands. Methodology development was lead by Restore America’s Estuaries with financial support from the National Estuarine Research Reserve System Science Collaborative, The National Oceanic and Atmospheric Administration’s Office of Habitat Conservation, The Ocean Foundation, The Curtis and Edith Munson Foundation, and KBR. ….
More extreme weather events likely: Climate projections of unparalleled accuracy for the whole of Europe
(December 4, 2013) — Scientists have analyzed climate projections for the whole of Europe at an unprecedented resolution of 12 km, by downscaling the global simulations carried out for the 5th IPCC report. These simulations for the 21st century now provide a much more detailed representation of local phenomena and extreme events. Initial analyses confirm that there will be a significant increase in the frequency of extreme events, such as heavy rainfall, heatwaves and droughts. … > full story

Humans threaten wetlands’ ability to keep pace with sea-level rise
(December 4, 2013) — Left to themselves, coastal wetlands can withstand rapid levels of sea-level rise. But humans could be sabotaging some of their best defenses, according to a new review. … The threat of disappearing coastlines has alerted many to the dangers of climate change. Wetlands in particular — with their ability to buffer coastal cities from floods and storms, and filter out pollution — offer protections that could be lost in the future. But, say co-authors Matt Kirwan and Patrick Megonigal, higher waters aren’t the key factor in wetland demise. Thanks to an intricate system of feedbacks, wetlands are remarkably good at building up their soils to outpace sea level rise. The real issue, they say, is that human structures such as dams and seawalls are disrupting the natural mechanisms that have allowed coastal marshes to survive rising seas since at least the end of the last Ice Age. “Tidal marsh plants are amazing ecosystem engineers that can raise themselves upward if they remain healthy, and especially if there is sediment in the water,” says co-author Patrick Megonigal of the Smithsonian Environmental Research Center. “We know there are limits to this, and worry those limits are changing as people change the environment.” “In a more natural world, we wouldn’t be worried about marshes surviving the rates of sea level rise we’re seeing today,” says Kirwan, the study’s lead author and a geologist at the Virginia Institute of Marine Science. “They would either build vertically at faster rates or else move inland to slightly higher elevations. But now we have to decide whether we’ll let them.”….> full story
Sea-level rise to drive coastal flooding, regardless of change in cyclone activity
(December 4, 2013) — Though recent studies focus on climate change impacts on intensity and frequency of tropical cyclones, a new review shows that sea level rise and shoreline retreat are the two more certain factors expected to drive an increase in future flood risk. … Sea level rise and its potential to dramatically change the coastal landscape through shoreline erosion and barrier island degradation, for example, is an under-appreciated and understudied factor that could lead to catastrophic changes in flood risk associated with tropical cyclones, known as hurricanes in the North Atlantic, they say. Woodruff adds, “There is general agreement that while globally, tropical cyclones will decline in frequency, their strength will be more intense. However, there is less consensus on the magnitude of these changes, and it remains unclear how closely individual regions of tropical cyclone activity will follow global trends.” Despite these uncertainties, the UMass Amherst geoscientist notes, the intensity and frequency of flooding by tropical cyclones will increase significantly due to accelerated sea level rise. Further, the geologic record provides clear examples for the importance of accelerated sea level rise in initiating significant changes in shoreline behavior.

Geoengineering approaches to reduce climate change unlikely to succeed
(December 5, 2013) — Reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change after all. Researchers used a simple energy balance analysis to explain how the Earth’s water cycle responds differently to heating by sunlight than it does to warming due to a stronger atmospheric greenhouse effect. Further, they show that this difference implies that reflecting sunlight to reduce temperatures may have unwanted effects on the Earth’s rainfall patterns. …
Global warming alters Earth’s water cycle since more water evaporates to the air as temperatures increase. Increased evaporation can dry out some regions while, at the same time, result in more rain falling in other areas due to the excess moisture in the atmosphere. The more water evaporates per degree of warming, the stronger the influence of increasing temperature on the water cycle. But the new study shows the water cycle does not react the same way to different types of warming…..
In the new Earth System Dynamics study the authors also show how these findings can have profound consequences for geoengineering. Many geoengineering approaches aim to reduce global warming by reducing the amount of sunlight reaching Earth’s surface (or, in the pot analogy, reduce the heat from the stove). But when Kleidon and Renner applied their results to such a geoengineering scenario, they found out that simultaneous changes in the water cycle and the atmosphere cannot be compensated for at the same time. Therefore, reflecting sunlight by geoengineering is unlikely to restore the planet’s original climate. “It’s like putting a lid on the pot and turning down the heat at the same time,” explains Kleidon. “While in the kitchen you can reduce your energy bill by doing so, in the Earth system this slows down the water cycle with wide-ranging potential consequences,” he says. Kleidon and Renner’s insight comes from looking at the processes that heat and cool Earth’s surface and how they change when the surface warms. Evaporation from the surface plays a key role, but the researchers also took into account how the evaporated water is transported into the atmosphere. They combined simple energy balance considerations with a physical assumption for the way water vapour is transported, and separated the contributions of surface heating from solar radiation and from increased greenhouse gases in the atmosphere to obtain the two sensitivities. One of the referees for the paper commented: “it is a stunning result that such a simple analysis yields the same results as the climate models.”….> full story

The 2014 Shrimp Season In The Gulf Of Maine Has Been Canceled
By Joanna M. Foster on December 4, 2013
On Tuesday, the Atlantic States Marine Fisheries closed the Northern shrimp fishery in the Gulf of Maine citing record low stocks. .. I think everyone was startled by what we saw in 2012, and there was a lot of pressure to close down the fishery for the 2013 season,” said John Annala, Chief Scientific Officer at the Gulf of Maine Research Institute. “The survey this summer found just 20 percent of the 2012 record low, so it has fallen off incredibly sharply.” Perhaps most worrying is the fact that juvenile shrimp have not been picked up in a survey since 2010. Northern shrimp live about five years, so the lack of younger shrimp for three years straight may mean empty nets for years to come. “During the last ten years the water temperature in the Gulf of Maine has been running about 2.5 degrees Celsius or about 5 degrees Fahrenheit warmer than the previous one hundred year average,” Annala said. “We don’t know what the thermal threshold of this species is, but the Gulf of Maine has always been the southernmost extreme of their range, so we probably don’t have much wiggle room.” Even if Northern shrimp prove themselves to be more heat tolerant than scientists predict, the warmer waters in the Gulf of Maine are proving deadly to the shrimp’s food supply, tiny zooplankton. Last spring, the usual surge in plankton never happened. Many species of plankton are also at the southernmost end of their thermal tolerance. Warmer waters are also making the Gulf more hospitable to shrimp predators like dogfish and red hake. “Decisions like this one show how fishermen are on the front lines of the battle against climate change,” said Michael Conathan, Director of Ocean Policy at the Center for American Progress in a phone interview. “This is not a nebulous, maybe-someday-in-the-future problem. This is unchecked carbon pollution affecting livelihoods here in Maine today.”….

New research predicts the continent to warm faster than the rest of the world, while also suffering increased droughts and deluges…. The research, which was conducted by 27 institutions and published this week in two scientific journals, found that by the end of the century, Europe could see average temperatures rise by 1 to 5 degrees Celsius, or 1.8 to 9.0 degrees Fahrenheit. That’s warmer than the IPCC’s most recent prediction of 0.3 to 4.8 degrees Celsius of average global warming by century’s end. The research also predicts an increase in heatwaves in south and central Europe and intense rainfall and droughts in Europe overall. That prediction is in line with previous research on extreme weather and climate change and is also in line with some of the extreme weather Europe has dealt with over the last decade. This summer, in the midst of a heatwave that baked much of Europe, Austria set an all-time high temperature record after one town hit 104.9 degrees F. And in 2003, a major heatwave caused 70,000 deaths in Europe. Another recent report from the European Academies Science Advisory Council found that over the last 30 years, Europe has experienced a 60 percent increase in damage costs of extreme weather events. And in October, a report from the Norwegian Meteorological Institute noted that extreme weather is “increasing in frequency and intensity within Europe” and made predictions of increasing droughts, extreme rainfall events, and heatwaves that backed up the most recent research.
Global Carbon Project Updates Data on the Carbon Budget
On November 19, 2013, the Global Carbon Project (GCP) published its annual update on the global carbon budget and emissions trends. International goals aim to reduce global emissions in order to keep global warming below 2 degrees Celsius, which requires limiting total global carbon dioxide (CO2) emissions to 1 trillion tons. GCP’s update, Carbon Budget 2013, tracks fossil fuel emissions to better understand the world’s current climate change situation, and what changes can be made to emissions trends to stay within our carbon budget The Carbon Budget 2013 reports that annual emissions have been steadily increasing, though the major contributors to such emissions have changed within the last several years. In 2005, developing countries surpassed developed countries as the greater contributors to climate change. This is due to emission levels falling in developed countries like the European Union and the United States, but skyrocketing in developing countries like China and India. Annual CO2 emissions from developing nations, which accounted for approximately one-third of global emissions in 1990, now account for nearly 60 percent of global emissions.

Winter is likely to offer little relief to the drought-stricken U.S. Southwest, and drought is likely to develop across parts of the Southeast as below-average precipitation is favored in these areas of the country, according to NOAA’s annual Winter Outlook announced today. Drought has been an ongoing concern across parts of the Southwest and Texas for nearly three years, and after some relief during the past few months, drought is likely to redevelop during winter. Sea surface temperatures across the equatorial Pacific have been near average since spring 2012, and forecasters expect that to continue through the winter. This means that neither El Niño nor La Niña is expected to influence the climate during the upcoming winter.

The world’s climate is changing fast, and will continue to do so for the foreseeable future, no matter what measures we now take to reduce humankind’s impact on it. And as temperatures rise, rainfall patterns and amounts change, and pests and diseases find new ranges, the face of world agriculture will have to change too. Humankind is facing enormous challenges in feeding everyone on the planet. The Food and Agriculture Organization of the United Nations (FAO) estimates that 842 million people went hungry in 2011-13; that’s one in eight people worldwide. And the human population is still growing. By 2050 there will be another 2.4 billion mouths to feed. We will have to increase the amount of food we produce by 70 percent to meet the extra demands placed by population growth and changes in diets.
Somewhat surprisingly, agriculture has, until recently, been on the sidelines of discussions of human-induced climate change. Once largely seen as a ‘victim’ of climate change, there is now, however, a growing recognition of both the contribution agriculture has made, and continues to make, to climate change and the role it can play in mitigating the impact of human activities on climate change……he Food and Agriculture Organization of the United Nations (FAO) defines climate-smart agriculture as consisting of three main pillars:
- sustainably increasing agricultural productivity and incomes (food security);
- adapting and building resilience to climate change (adaptation); and
- reducing and/or removing greenhouse gas emissions (mitigation), where possible.
But what exactly is “climate-smart agriculture”? Broadly speaking, it consists of proven practical techniques, such as mulching, intercropping, conservation agriculture, crop rotation, integrated crop-livestock management, agro-forestry, improved grazing, and improved water management, together with innovative practices, such as better weather forecasting, drought- and flood-tolerant crops, and crop and livestock insurance. A quick search online shows that many agencies and projects have are testing or promoting climate-smart agriculture, but few have shown widespread uptake. But a new booklet,
Climate-smart agriculture — Success stories from farming communities around the world, shows that climate-smart agriculture can and does make a difference to millions of people’s lives. The booklet showcases 16 examples of successful climate-smart agriculture from both developed and developing countries.

Climate change is about people. It’s about livelihoods that are affected and sometimes destroyed when severe weather ravages the land they depend on for income. It’s about displacement when they are then forced to leave home in search of a better life in communities that do not have the capacity to absorb them. And it’s about survival in areas that do not have the infrastructure in place to withstand extreme weather…..

Continuing with pledge pathways to 2030 could push climate goals out of reach
(December 3, 2013) — Current pledges for greenhouse gas emission reductions are inadequate and will further increase the challenge to reach internationally agreed climate targets, according to new research. … In the absence of a global agreement on emission limits, countries instead have made voluntary pledges to reduce their emissions by 2020 with the current negotiations trying to establish international agreements for emissions reductions for the year 2030. The mitigation effort of the 2020 pledges made by countries under the UN Framework Convention on Climate Change would result in significantly higher emissions in 2030 than what would be cost-effective in order to reach the long-term climate targets acknowledged by that treaty, according to a new study by research teams from Europe, Asia and the United States published in the journal Technological Forecasting and Social Change. “The gap between where emissions are and where emissions would need to be in order to keep climate targets within reach is getting bigger and bigger,” says IIASA Energy Program Leader Keywan Riahi, lead author of the paper published today. “Our study brings together the leading research teams in the field to systematically assess the implications of this gap.”….> full story

Contrast that to the Rainforest Action Network’s most recent Coal Finance Report Cards, which cite Goldman as large supporters of both mountain-top removal (MTR) coal mining and coal-fired power plants. The process of MTR uses explosives to blow up mountains in order to access coal reserves, forcing rocks and soil into valleys and increasing concentrations of mercury and arsenic in water supplies. Until this year, Goldman did not have any policy statements addressing the issue of MTR mining and its associated risks, while doing business in 2011 with Arch Coal and Alpha Natural Resources — the two largest MTR companies. Now, Goldman does have a due diligence policy for MTR transactions, which states that “we review companies’ environmental, health and safety track record, regulatory compliance, litigation and local community issues, remediation methods, and impact on water quality.” In 2012, Goldman financed both Alpha and Walter Energy, which cumulatively produced 29.42 percent of MTR coal mined in Appalachia that year, the RAN’s report said. In terms of coal-fired power involvement, Goldman provided $252 million in financing “as a lead arranger or lead manager in transactions” with coal-fired power companies profiled in the RAN’s 2013 report. Coal-fired power companies financed by Goldman include American Electric Power, Berkshire Hathaway, Duke Energy, Energy Future Holdings, FirstEnergy, NRG Energy, and the Southern Company.
Goldman has recently indicated that the “window for profitable investment in coal mining is closing,” saying in a recent research paper that that competition from gas and renewable energy is slowing down the market; environmental regulations are discouraging coal-fired generation; and that improvements in energy efficiency are making investments there more viable. But Goldman’s pessimistic view of coal, according to its paper, is not based around a belief that action to address climate change will stop the coal market. In fact, the paper said, “climate change has been displaced by other issues as a top concern.” However, the bank said “a catastrophic weather event such as an ice-free summer at the North Pole, a particularly destructive hurricane season in North America or a weather disruption that materially impacts agricultural output. Under such a scenario, governments may be forced to respond with drastically tighter environmental regulations that would further erode the long term demand for coal.”…

In an effort to compensate for the failure of central governments to address the dangers of climate change with comprehensive national policies, cities, states and regions have developed their own strategies to rein in emissions of carbon dioxide and other greenhouse gases. California’s ambitious plan aims to reduce emissions 80 percent by 2050 by requiring cleaner cars, more energy-efficient buildings and renewable fuels. Nine northeastern states have joined in a regional trading program aimed at reducing power-plant emissions.

SYDNEY — Huge clumps of strange, pink-stringed jellyfish drifted into the protected bay near my home in Sydney last year. Thousands swarmed under the surface, stinging indiscriminately. I swam through them in a full-body wet suit for several long months with my swimming group, wondering if warmer currents had changed the habitat patterns. Scientists are now talking about a peculiar “jellification” of the sea, prompted by climate change. We smeared ointments on our faces and packed antihistamines and creams for the red welts on our exposed skin.

When President Obama made his second State of the Union address, he talked extensively about the importance of addressing global climate change. “For the sake of our children and our future, we must do more,” he said. “But if Congress won’t act soon to protect future generations, I will. I will direct my Cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy.” Obama now seems to be making good on those statements. On Thursday, the administration released an executive order directing the federal government to triple its use of renewable energy by 2020, which would bring the government’s renewable energy usage to 20 percent. The order will apply to all federal agencies, including the military. The Associated Press, which obtained a copy of the executive order before it was published, noted that the federal government itself occupies approximately 500,000 buildings and operates 600,000 vehicles, and purchases more than $500 billion per year in goods and services. The order does not disclose the cost of the transition, but says the goal will be reached “to the extent economically feasible and technically practicable.” ….

Kindergartners in Manhattan being served lunch on plates made from sugar cane, which are expected to replace plastic foam trays next year in six districts.
Nothing seemed special about the plates from which students at a handful of Miami schools devoured their meals for a few weeks last spring — round, rigid and colorless, with four compartments for food and a fifth in the center for a carton of milk. Six big-city school districts are working to persuade suppliers to sell healthier and more environment-friendly products, like compostable food trays.
The new plates can be thrown away with any uneaten food and turned into compost. Looks, however, can be deceiving: They were the vanguard of what could become an environmental revolution in schools across the United States. With any uneaten food, the plates, made from sugar cane, can be thrown away and turned into a product prized by gardeners and farmers everywhere: compost. If all goes as planned, compostable plates will replace plastic foam lunch trays by September not just for the 345,000 students in the Miami-Dade County school system, but also for more than 2.6 million others nationwide. …

Nelson Mandela, who died yesterday at age 95, leaves two legacies for climate hawks — the necessity of persistence and the value of divestment. Who among us can even imagine the persistence required of a man who spent more than 27 years in jail — from 1962 to 1990 — in his quest to end Apartheid? But his indefatigable spirit triumphed, and he was elected the first black president of South Africa a little more than 4 years after his release. His forbearance and moral sensibility prevented what many saw as an inevitable civil war and achieved, instead, national reconciliation.
Desmond Tutu wrote in a 2010 WWF editorial: “Last month we saw celebrations marking 20 years since the release of Nelson Mandela. That historic day signaled a turning point in the path this country was to take; we embarked on a new journey filled with hope for the future. Indeed, there were many who had to pinch themselves when it happened, so bleak were the preceding months and years during which many South Africans saw their country in crisis. The global movement urging action on climate change should take heart from that great event…. It took individual and collective activism and a sense of urgency and responsibility to change our nation. Twenty years later that’s what it will take to change the world.”
Climate hawks have already begun to take a page out of the strategy that helped bring down apartheid. Bill McKibben discussed that very point in a 2012 National Journal profile: McKibben now plans to pressure U.S. institutions, starting with universities, to end their financial investments in oil, gas, and coal companies. He’ll launch a 20-college tour, joined by Nobel laureate and South African human-rights activist Archbishop Desmond Tutu, to pressure university boards, via student protests, to end university endowment’s holdings in fossil fuels.
“Two hundred colleges divested their holdings in companies that did business with South Africa. And when Nelson Mandela got out of prison, the first place he came was not the White House—it was California to thank University of California students who had helped get their system to divest $3 billion in holdings in South Africa,” McKibben said. “As Desmond Tutu says, this is the next great moral issue that we face, and the same kind of tactic is what’s necessary to face it.”
Economy-wide divestment from fossil fuels is inevitable (see “Invest, Divest: Renewable Investment To Hit $630 Billion A Year In 2030, Fossil Fuel Stocks At Risk Today”). But, as I’ve written, we are poised to miss the window to avert catastrophic climate change by just a decade or two — resulting in possibly hundreds of years of misery for billions and billions of people. That’s why climate hawks must redouble our efforts against our redoutable opponents. Indeed, former Prime Minister Gordon Brown wrote in 2010 that this was the heartening lesson Mandela’s persistence held for those tackling “the great causes of today” such as climate change: “And so the lesson of the South African struggle is surely that change never comes without a fight, but when we fight, progressives can change the course of history.”
Mandela famously said, “it always seems impossible until it’s done.” But he had so many inspirational quotes. In his 1995 book, “Long Walk to Freedom,” he wrote, “There were many dark moments when my faith in humanity was sorely tested, but I would not and could not give myself up to despair. That way lays defeat and death.”
And, finally, he also wrote this: I have walked that long road to freedom. I have tried not to falter; I have made missteps along the way. But I have discovered the secret that after climbing a great hill, one only finds that there are many more hills to climb. I have taken a moment here to rest, to steal a view of the glorious vista that surrounds me, to look back on the distance I have come. But I can rest only for a moment, for with freedom comes responsibilities, and I dare not linger, for my long walk is not yet ended.

Former South African President’s philosophy and life offers important lessons for climate justice campaigners, writes
(Pic: Flickr/Symphony Of Love)
“Sometimes it falls upon a generation to be great, you can be that generation”
As the life of one of the world’s great heroes draws to a close it provides an important opportunity to reflect back on Nelson Mandela’s long and courageous life in order to draw inspiration from one of the world’s moral stalwarts who weathered the storms of oppression, racism, injustice and inequality & not only managed to come out of the other side a smiling, compassionate & forgiving leader, but in doing so navigated a path through those storms which has helped to inspire generations of leaders to come.
While climate change was not the issue that defined Mandela’s Long Walk to Freedom, a reflection on Mandela’s philosophy and life reveals a profound overlap with the principles and commitments of the climate justice movement, and therein lies many important lessons not only for the climate community but for humanity as a whole to learn from.
One prominent example is Mandela’s commitment to a cosmopolitan ethic of Ubuntu. Contrary to a strong individualism which permeates the Western world, the ethic of Ubuntu when combined with Mandela’s cosmopolitan valuing of all humanity, says that our own identity and well-being is tied into that of our community, the global community of humanity….. As we figure out how to respond to this crazy climate predicament we are in, reflecting on the life and struggles of Nelson Mandela can provide many important lessons as to how we make the seemingly impossible possible and become Mandela’s great generation, remembering , in the words of Mandela, that “it always seems impossible until it’s done“. – See more at: http://www.rtcc.org/2013/12/06/nelson-mandelas-legacy-to-climate-change-activists/#sthash.WY3cW3Jf.dpuf
