| Ancient Climate Change Has Left a Strong Imprint On Modern Ecosystems |
| As Earth's climate cycles between warm and cool periods, species often must move to stay within suitable conditions. Scientists have now mapped how fast species have had to migrate in the past to keep up with changing climate. They found that small-ranged species — which constitute much of Earth's biodiversity — are concentrated in regions where little migration has been required. Climate change due to human activities will drastically increase the required migration rates in many of these locations, putting their unique faunas at risk. |

| Two species of gorillas live in central equatorial Africa. Divergence between the Western gorillas (Gorilla gorilla) and Eastern Gorillas (G. beringei) began between 0.9 and 1.6 million years ago and now the two species live several hundred kilometres apart. New research published by BioMed Central's open access journal BMC Evolutionary Biology shows that the divergence of Western lowland gorillas and the Critically Endangered Cross River gorillas (G. g. diehli) occurred more recently, about 17,800 years ago, during the Pleistocene era. |

| CO2 capture: Health effects of amines and their derivatives |
| CO2 capture by means of amines is considered to be the most appropriate method to quickly begin with CO2 removal. During this capture process, some of the amines escaping the recycling process will be emitted into the air and will also form other compounds such as nitrosamines and nitramines. The Norwegian Institute of Public Health (NIPH) was commissioned by the Climate and Pollution Agency (Klif) to assess whether these new emissions are harmful to health - particularly in terms of the cancer risk to the general population. The results of the risk assessments were submitted recently. |

| CO2 exacerbates oxygen toxicity |
| French research team at the Laboratoire de Chimie Bacterienne has demonstrated that carbon dioxide (CO2) plays a role in the formation of oxidative damage in vivo. Under conditions of oxidative stress, certain types of damage (cell death, some DNA lesions, mutation frequency, etc.) affecting the model organism Escherichia coli tend to increase depending on the level of atmospheric CO2. The CO2 levels studied range from 40 ppm(1) to the current projections for 2100 (1,000 ppm). The results indicate that the predicted increase in atmospheric CO2 should have a direct effect on living organisms. A paper on this work will be published in the February 25, 2011 issue of EMBO Reports. |

| Contemporary climate change alters the pace and drivers of extinction |
| Local extinction rates of American pikas have increased nearly five-fold in the last 10 years, and the rate at which the climate-sensitive species is moving up mountain slopes has increased 11-fold, since the 20th century, according to a study soon to be published in Global Change Biology. The research strongly suggests that the American pika's distribution throughout the Great Basin is changing at an increasingly rapid rate. The pika (Ochotona princeps), a small, hamster-looking animal sensitive to climate, occurs commonly in rocky talus slopes and lava flows throughout the western U.S. The study demonstrates a dramatic shift in the range of this rabbit relative, and illustrates the increasingly important role of climate in the loss of local pika populations across the nearly 150,000 square miles of the hydrological Great Basin. |

| For the first time, researchers have developed a comprehensive approach to look at aerosols—those fine particles found in pollution—and their effect on clouds and climate. Scientists from Pacific Northwest National Laboratory improved how aerosols are accounted for in a global climate model used to predict climate change by embedding a high-resolution model in each climate grid. The embedded model replaces parameterization, a simplified method currently used to reckon small-scale climate processes. The new integrated approach brings the small scale to the global scale, for more effective climate modeling. |

| The continuing increase in the level of carbon dioxide and other "greenhouse gases" in the Earth's atmosphere has been identified as a cause for serious concern because it may radically accelerate changes in the Earth's climate. Developing an effective strategy for managing the planet's greenhouse gases is complicated by the many and varied sources of such gases, some natural, some man-made, as well as the mechanisms that capture and "sequester" the gases. A new report sponsored by the National Institute of Standards and Technology (NIST) focuses on one of the key challenges: defining and developing the technology needed to better quantify greenhouse gas emissions. |

| The woolly rhinoceros, woolly mammoth, wild horse, reindeer, bison, and musk ox -- is the subject of a study by an international group of scientists investigating how climate fluctuations and human activity affected mammal populations at the end of the last ice age. According to Beth Shapiro, the Shaffer Associate Professor of Biology at Penn State University and a member of the research team, both climate change and humans were responsible for the extinction of some cold-adapted animals and the near extinction of others. The results of the study, which is the first to use genetic, archeological, and climatic data together to infer the population history of large-bodied Ice-Age mammals, will be published in the journal Nature. The study's findings are expected to shed light on the possible fates of living species of mammals as our planet continues its current warming cycle. |

| Hurricane damage to forests: Scientists study impacts on carbon cycle |
| When we think of carbon emissions that exacerbate global climate change most of us probably think of the exhaust from automobiles and other vehicles, or smoke billowing from rows of stacks at fossil fuel-burning power plants. But there is a source of large carbon emissions that is not so immediately obvious — the destruction of forest trees through hurricanes. For example, studies led by Jeffrey Chambers, who is now with the Lawrence Berkeley National Laboratory (Berkeley Lab), have shown that Hurricane Katrina, the storm that flooded New Orleans and pounded the Gulf coastal areas of Mississippi and Louisiana, uprooted or severely damaged roughly 320 million trees. In terms of the carbon cycle, this devastating loss of vegetation from a single storm was equivalent to about a 10-percent increase in U.S. fossil fuel emissions for a year. |

| Land use change influences continental water cycle |
| Forests, and tropical forests in particular, play an important role in the global water cycle. Delft University of Technology PhD researcher Ruud van der Ent (TU Delft, The Netherlands) has recently shown that evaporation from the Amazon forest is for more than 50% responsible for the rainfall in Peru, Bolivia, Argentina, Uruguay, Paraguay and southern Brazil, where it feeds crops and rivers. Similarly in Africa, the Congo forest exports tons of water through the atmosphere to the West-African countries. Van der Ent also shows that land use changes such as irrigation, dams, and deforestation can alter evaporation patterns in a region, potentially affecting water resources in distant regions. With his research, Van der Ent has won the 2011 WMO (World Meteorological Organization) Research Award for Young Scientists. |

| Large Global Potential for Negative CO2 Emissions Through Biomass Linked With Carbon Dioxide Capture and Storage |
| Combining biomass with carbon dioxide capture and storage could result in an annual global potential of up to 10 gigatonnes of negative CO2 emissions in the year 2050. This is one of the main findings of a study commissioned by IEA Greenhouse Gas R&D Programme to the global energy consultancy company Ecofys. Compared to the almost 31 gigatonnes of global energy-related CO2 emissions in 2010, this represents a huge CO2 emissions reduction potential. |

| Long-Term Carbon Storage in Ganges Basin May Portend Global Warming Worsening |
| Woods Hole Oceanographic Institution (WHOI) scientists have found that carbon is stored in the soils and sediments of the Ganges-Brahmaputra basin for a surprisingly long time, making it likely that global warming could destabilize the pool of carbon there and in similar places on Earth, potentially increasing the rate of CO2 release into the atmosphere. The study, published in the current online edition of Nature Geoscience, examined the radiocarbon content of river sediments collected from the Ganges-Brahmaputra system draining the Himalayas. The basin, the scientists say, "represents one of the largest sources of terrestrial biospheric carbon to the ocean." |

| Natural gas can play major role in greenhouse gas reduction |
| Natural gas is important in many sectors of the economy: for generating electricity, as a heat source for industry and buildings, and in chemical feedstock. Given the abundance of natural gas available through large global resources and the recent emergence of substantial unconventional supplies in the United States, worldwide usage of the fuel is likely to continue to grow considerably and contribute to significant reductions of greenhouse gas emissions for decades to come, according to a comprehensive, multidisciplinary study carried out over the last three years by MIT researchers. |

| New Material Can Scrub Carbon Dioxide Right Out of the Air at Unprecedented Rates |
| If cleaning carbon dioxide from the atmosphere was easy, we’d already be doing it. But carbon capture has proven to be a tough technology to feasibly roll out on a grand scale, and that means all the things we do that produce carbon dioxide emissions--which seems to be just about everything these days--are still roughly as bad for the planet as they were several years ago. That’s a problem in a warming world, and one that a team of researchers may have just found a solution for via an inexpensive polymeric material. |

| In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator. While previous work has shown that the ozone hole is changing the atmospheric flow in the high latitudes, the Columbia Engineering paper, "Impact of Polar Ozone Depletion on Subtropical Precipitation," demonstrates that the ozone hole is able to influence the tropical circulation and increase rainfall at low latitudes in the Southern Hemisphere. This is the first time that ozone depletion, an upper atmospheric phenomenon confined to the polar regions, has been linked to climate change from the Pole to the equator. |

| Ocean acidification leaves clownfish deaf to predators |
| Since the Industrial Revolution, over half of all the CO2 produced by burning fossil fuels has been absorbed by the ocean, making pH drop faster than any time in the last 650,000 years and resulting in ocean acidification. Recent studies have shown that this causes fish to lose their sense of smell, but a new study published today in Biology Letters shows that fish hearing is also compromised. |

| Ocean acidification may directly harm fish: study |
| Fossil fuel combustion, and with it the release of heat-trapping carbon dioxide (CO2), is still growing globally. Beyond climate change, this is also causing the world's "other CO2 problem," ocean acidification, i.e., the formation of carbonic acid when CO2 from the atmosphere enters seawater. Studies have already demonstrated a multitude of negative effects of elevated CO2 conditions for many groups of marine organisms such as corals, plankton, shellfish and sea urchins. To date, scientists have assumed marine fish were immune to ocean acidification. |

The growth in calcium carbonate, which these shells experience every year, means that they "store" information on climatic conditions in high temporal resolution. A project conducted by the Austrian Science Fund FWF has recently analysed this growth. The identified change in the annual seasonality pattern during that period is surprising, as scientists had only been aware of a major temperature decline to date. |

| Peat bogs will not cause runaway global warming |
| OK, so the world has warmed up a bit since 1950. This is terrible, because it means that the huge amounts of carbon stored in peat bogs will now start to be emitted into the atmosphere, which will cause more warming, which will release more peaty carbon and so on until all the Earth is a baking lifeless hell. |

| Steep increase in global CO2 emissions despite reductions by industrialized countries |
| Global emissions of carbon dioxide (CO2) — the main cause of global warming — increased by 45 % between 1990 and 2010, and reached an all-time high of 33 billion tonnes in 2010. Increased energy efficiency, nuclear energy and the growing contribution of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries. |

| Structural Self-Replication Based on DNA Could Create New Materials |
| One of the hallmarks of living things is self-replication, the ability to make new copies of biological structures. Scientists have harnessed this ability in several ways, using DNA and viruses to organize materials for things like solar panels. But inducing artificial self-replication, which would enable new types of self-fabricating materials, has proven more difficult. Now researchers at New York University say they’ve taken a step in that direction, building a complex artificial system that can self-replicate. |

| Study finds local temperature influences belief in global warming |
| A study by Columbia Business School Professor Eric Johnson, co-director of the Center for Decision Sciences at Columbia Business School, Ye Li, a postdoctoral researcher at the Center for Decision Sciences, and Lisa Zaval, a Columbia graduate student in psychology, found that those who thought the current day was warmer than usual were more likely to believe in and feel concern about global warming than those who thought the day was unusually cold. The study, recently featured in Psychological Science, explains why public belief in global warming can fluctuate, since people can base their thinking off of the day's temperature. The researchers behind this study are also affiliated with Columbia University's Center for Research on Environmental Decisions, CRED. |

| Study shows developed nation's reduction in CO2, outpaced by developing country emissions |
| In a paper published in Proceedings of the National Academy of Sciences, a group of researchers and scientists show that the gains that have been made in stabilizing CO2 emissions in developed or "rich" countries since the signing of the Kyoto agreement, have been neutralized by the increase in CO2 emissions from developing nations as they produce goods for trade, primarily to developed countries. Because of this disparity, many groups are calling for a change to the Kyoto agreement practice of only counting CO2 emissions that are produced in-country, rather than the CO2 footprint of those products that are consumed. |

| Sugarcane cools climate |
| Brazilians are world leaders in using biofuels for gasoline. About a quarter of their automobile fuel consumption comes from sugarcane, which significantly reduces carbon dioxide emissions that otherwise would be emitted from using gasoline. Now scientists from the Carnegie Institution's Department of Global Ecology have found that sugarcane has a double benefit. Expansion of the crop in areas previously occupied by other Brazilian crops cools the local climate. It does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants "exhale" cooler water. The study is published in the 2nd issue of Nature Climate Change, posted on-line April 17. |

| Summer drought limits the positive effects of CO2 and heat on plant growth in future climate |
| The large scale project CLIMAITE, led by Riso DTU, has published its first synthesis paper in the renowned journal Global Change Biology, and the conclusion is perhaps a little surprising that the predicted increase in plant growth, due to more CO2 in the atmosphere is noticeably limited when combined with higher temperatures - and especially summer droughts. |

| Supreme Court's Global-Warming Decision Keeps The Cause Alive |
| The U.S. Supreme Court's decision in AEP v. Connecticut was a clear-cut victory for the utilities who were being sued by Connecticut and several other states over their greenhouse gas emissions. The court ruled that the Environmental Protection Agency occupies this particular field of battle and the states couldn't sue. The decision turns on the tricky area of "federal common law," however, a rarely-invoked branch of the law that governs things like environmental disputes between states. As my guest commentator below, Stanley N. Alpert of Constantine Cannon explains, the high court left plenty of ammunition for environmentalists in its ruling. Alpert's worth listening to: For 13 years he was an assistant U.S. Attorney, specializing in environmental cases for much of that time. |

| Swift action can help protect rice farmers in Sahel from climate change |
| Rice farmers in the Sahel region will be able to successfully grow rice in a sustainable way despite climate change if they amend their irrigation in the short term and rice varieties are developed able to cope with higher temperatures. This is the result of research with which Michiel de Vries hopes to obtain his doctorate at Wageningen University on September 14, 2011. The study combines computer models and field experiments to show how farmers can save up to 40 percent on water consumption while maintaining a good yield. |

| Technology funding makes climate protection cheaper |
| To cost-effectively protect the climate, not only an emissions trading scheme but also financial support for new technologies is needed. Economising on targeted funding, for example for renewable energies, makes climate protection more expensive — as scientists of the Potsdam Institute for Climate Impact Research (PIK) now calculated for the first time, using a complex computer simulation that spans the entire 21st century. Without funding, energy technologies with high cost reduction potentials will hardly stand a chance, since they require a significant initial investment: a case of market failure. |

| Testing Geoengineering: Models Help Determine Type of Testing That Might Be Effective |
| Solar radiation management is a class of theoretical concepts for manipulating the climate in order to reduce the risks of global warming caused by greenhouse gasses. But its potential effectiveness and risks are uncertain, and it is unclear whether tests could help narrow these uncertainties. A team composed of Caltech's Doug MacMynowski, Carnegie's Ken Caldeira and Ho-Jeong Shin, and Harvard's David Keith used modeling to determine the type of testing that might be effective in the future. |

| Thawing tundra a new climate threat |
| A significant source of greenhouse gases has started leaking into the Earth's atmosphere from an unlikely place. Above the Arctic Circle, land frozen for tens of thousands of years has begun to thaw for the first time. Current estimates indicate that perennially frozen ground, called permafrost, holds more than twice the amount of carbon present in today's atmosphere. As permafrost thaws, a huge amount of this stored carbon could be released as carbon dioxide or methane gas. |

| The case of the dying aspens |
| Over the past 10 years, the death of forest trees due to drought and increased temperatures has been documented on all continents except Antarctica. This can in turn drive global warming by reducing the amount of carbon dioxide removed from the atmosphere by trees and by releasing carbon locked up in their wood. New research led by Carnegie researcher and Stanford University PhD student William Anderegg offers evidence for the physiological mechanism governing tree death in a drought. The work is published the week of December 12 by the Proceedings of the National Academy of Sciences. |

| Wandering Albatross Alters Its Foraging Due to Climate Change |
| Paris/ Leipzig. Wandering albatrosses have altered their foraging due to changes in wind fields in the southern hemisphere during the last decades. Since winds have increased in intensity and moved to the south, the flight speed of albatrosses increased and they spend less time foraging. As a consequence, breeding success has improved and birds have gained 1 kilogram. These are the results of the study of an international research team published in the latest issue of the Science journal. However, these positive consequences of climate change may last short if future wind fields follow predictions of climate change scenarios, researchers warn. |
