Reducing greenhouse gases may not be enough to slow climate change
Because land use changes are responsible for 50 percent of warming in the US, policymakers need to address the influence of global deforestation and urbanization on climate change, in addition to greenhouse gas emissions. view more (2009-11-11)
Despite Awareness of Global Warming Americans Concerned More about Local Environment
Last week, British Prime Minister Gordon Brown declared climate change a top international threat, and Al Gore urged politicians to get involved to fight global warming. Results from a recent survey conducted by a University of Missouri professor reveal that the U.S. public, while aware of the deteriorating global environment, is concerned... view more...

NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic. view more (2006-03-15)
Models look good when predicting climate change
The accuracy of computer models that predict climate change over the coming decades has been the subject of debate among politicians, environmentalists and even scientists. view more (2008-04-03)
Scientists debate the accuracy of Al Gore's documentary
There is no question that Al Gore's 2006 documentary An Inconvenient Truth is a powerful example of how scientific knowledge can be communicated to a lay audience. What is up for debate is whether it accurately presents the scientific argument that global warming is caused by human activities. view more (2008-04-15)
Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences. view more (2006-04-11)
Greenhouse gas/temperature feedback mechanism may raise warming beyond previous estimates
A team of European scientists reports that climate change estimates for the next century may have substantially underestimated the potential magnitude of global warming. view more (2006-05-22)
Carbon dioxide role in past climate revealed
Researchers at the British Antarctic Survey (BAS) and the University of California, Santa Cruz have discovered that Earth's last great global warming period, 3 million years ago, may have been caused by levels of CO2 in the atmosphere similar to today's. view more (2005-04-11)
Entire lakes feel effects of climate warming, University of Alberta study shows
Climate warming brought on in part by human activities is producing major ecological changes in remote arctic lakes at an alarming rate. view more (2005-10-19)
Global warming of the future is projected by ancient carbon emissions
Global warming 55 million years ago suggests a high climate sensitivity to carbon dioxide, according to research led by Mark Pagani, associate professor of geology and geophysics at Yale and published in the December 8 issue of Science. view more (2006-12-08)
Storage of greenhouse gasses in Siberian peat moor
Wet peat moorlands form a sustainable storage place for the greenhouse gas carbon dioxide but are also a source of the much stronger greenhouse gas methane. According to Dutch researcher Wiebe Borren, peat moorlands will counteract the greenhouse effect under the present climatic conditions. view more (2007-01-31)
Glacial melting may release pollutants in the environment
Those pristine-looking Alpine glaciers now melting as global warming sets in may explain the mysterious increase in persistent organic pollutants in sediment from certain lakes since the 1990s, despite decreased use of those compounds in pesticides, electric equipment, paints and other products. view more (2009-10-22)
Health toll of climate change seen as ethical crisis
The public health costs of global climate change are likely to be the greatest in those parts of the world that have contributed least to the problem, posing a significant ethical dilemma for the developed world, according to a new study. view more (2007-11-08)
Forests damaged by Katrina may contribute to global warming
Researchers led by biologist Jeffrey Chambers of Tulane University have determined that the losses inflicted by Hurricane Katrina on Gulf Coast forest trees are enough to cancel out a year's worth of new tree biomass (trunks, branches and foliage) growth in other parts of the country. view more (2007-11-16)
Global warming will negatively impact tropical species
Global warming is likely to reduce the health of tropical species, scientists from UCLA and the University of Washington report May 6 in Proceedings of the National Academy of Sciences. view more (2008-05-06)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)
Time to lift the geoengineering taboo
Hot on the heels of the Royal Society's Geoengineering the Climate report, September's Physics World contains feature comment from UK experts stressing the need to start taking geoengineering - deliberate interventions in the climate system to counteract man-made global warming - more seriously. view more (2009-09-01)
Shift toward services industries won't end global warming
The shift toward a service-based economy won't automatically reduce the amount of greenhouse gases (GHS) in the air, a University of Minnesota researcher has found. His research contradicts assumptions about global warming often preferred by some economists and national policy experts. view more (2006-11-02)
Dried mushrooms slow climate warming in Northern forests
The fight against climate warming has an unexpected ally in mushrooms growing in dry spruce forests covering Alaska, Canada, Scandinavia and other northern regions, a new UC Irvine study finds. view more (2008-11-03)
Crops feel the heat as the world warms
Over a span of two decades, warming temperatures have caused annual losses of roughly $5 billion for major food crops, according to a new study by researchers at the Carnegie Institution and Lawrence Livermore National Laboratory. view more (2007-03-16)
