Rapidly warming climate is likely to seriously alter crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave half the world's population facing serious food shortages, new research shows. http://www.physorg.com/news150646556.html Other Sciences Thu, 08 Jan 2009 14:15:56 EST news150646556 A new way to reduce carbon dioxide emissions and tackle climate change had been unveiled by leading economists. http://www.physorg.com/news150446777.html Space & Earth Tue, 06 Jan 2009 06:46:17 EST news150446777 In a recently conducted study, a multidisciplinary French-American research team with expertise in archaeology, past climates, and ecology reported that Neanderthal extinction was principally a result of competition with Cro-Magnon populations, rather than the consequences of climate change. http://www.physorg.com/news149769271.html Other Sciences Mon, 29 Dec 2008 10:34:31 EST news149769271 Future increases in wind strength along the California coast may have far-reaching effects, including more intense upwelling of cold water along the coast early in the season and increased fire danger in Southern California, according to researchers at the Climate Change and Impacts Laboratory at the University of California, Santa Cruz. http://www.physorg.com/news148911966.html Space & Earth Fri, 19 Dec 2008 12:26:06 EST news148911966 The United States could suffer the effects of abrupt climate changes within decades -sooner than some previously thought--says a new government report. It contends that seas could rise rapidly if melting of polar ice continues to outrun recent projections, and that an ongoing drought in the U.S. west could be the start of permanent drying for the region. Commissioned by the U.S. Climate Change Science Program, the report was authored by experts from the U.S. Geological Survey, Columbia University's Lamont-Doherty Earth Observatory and other leading institutions. It was released at this week's meeting of the American Geophysical Union. http://www.physorg.com/news148907969.html Space & Earth Fri, 19 Dec 2008 11:19:29 EST news148907969 (PhysOrg.com) -- It's no simple matter to figure out how regional changes in precipitation, expected to result from global climate change, may affect water supplies. Now, a new analysis led by MIT researchers has found that the changes in groundwater may actually be much greater than the precipitation changes themselves. http://www.physorg.com/news148836122.html Space & Earth Thu, 18 Dec 2008 15:22:02 EST news148836122 Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive. These early conservationists disappeared 500 years ago, but centuries later, their soil is still rich in organic matter and nutrients. Now, scientists, environmental groups and policymakers forging the next world climate agreement see biochar not only as an important tool for replenishing soils, but as a powerful tool for combating global warming. http://www.physorg.com/news148758064.html Space & Earth Wed, 17 Dec 2008 17:41:04 EST news148758064 (PhysOrg.com) -- It`s no simple matter to figure out how regional changes in precipitation, expected to result from global climate change, may affect water supplies.

The researchers report in the December 12, 2008 issue of Science that during a time of climate change 13 million years ago the chemical makeup of the oceans changed dramatically. The researchers warn that the chemical composition of the ocean today could be similarly affected by climate changes now underway - with potentially far-reaching consequences for marine ecosystems. http://www.physorg.com/news148227653.html Space & Earth Thu, 11 Dec 2008 14:20:53 EST news148227653 Climate change can have significant impacts on high-elevation lakes and imperiled Sierra Nevada Yellow-legged frogs that depend upon them, according to U.S. Forest Service and University of California, Berkeley, scientists. http://www.physorg.com/news148223511.html Biology Thu, 11 Dec 2008 13:11:51 EST news148223511 Biochar, similar to charcoal used by pre-Columbian Amazonian cultures to boost crop yields, could help the fight against climate change by securely locking carbon away in soils for thousands of years, according to the December-January issue of ECOS magazine. http://www.physorg.com/news148053279.html Space & Earth Tue, 09 Dec 2008 13:54:39 EST news148053279 Scientists from around the world proved their green credentials by participating in a conference on climate change and carbon dioxide storage in the virtual world, this week (3 December). http://www.physorg.com/news147702946.html Technology Fri, 05 Dec 2008 12:35:46 EST news147702946 Climate change is hampering the long-term recovery of rivers from the effects of acid rain, with wet weather offsetting improvements, according to a new study by Cardiff University. http://www.physorg.com/news147505680.html Space & Earth Wed, 03 Dec 2008 05:48:00 EST news147505680 Organizations in the United States that are at the highest risk of sustaining damage from climate change are not adapting enough to the dangers posed by rising temperatures, according to a Yale report. http://www.physorg.com/news147444502.html Space & Earth Tue, 02 Dec 2008 12:48:22 EST news147444502 Plants that range northward because of climate change may be better at defending themselves against local enemies than native plants. http://www.physorg.com/news146328549.html Biology Wed, 19 Nov 2008 14:49:09 EST news146328549 Climate change is an unprecedented global problem and an emerging carbon finance market will play a critical role in addressing it, asserts a newly published Yale report. http://www.physorg.com/news145274773.html Space & Earth Fri, 07 Nov 2008 10:06:13 EST news145274773 (PhysOrg.com) -- Drawing on records dating back to the journals of Henry David Thoreau, scientists at Harvard University have found that different plant families near Walden Pond in Concord, Mass., have borne the effects of climate change in strikingly different ways. Some of the plant families hit hardest by global warming have included beloved species like lilies, orchids, violets, roses, and dogwoods. http://www.physorg.com/news144511715.html Biology Wed, 29 Oct 2008 15:08:35 EST news144511715 Carbon dioxide will continue to rise even if current national and international targets for reducing emissions are met, scientists warn. But, they say, strong action taken now - such as the 80% target recently announced by the UK government - will continue to have benefits a long time into the future. http://www.physorg.com/news144419668.html Space & Earth Tue, 28 Oct 2008 13:34:28 EST news144419668 (PhysOrg.com) -- Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. But a new study led by a University of Georgia researcher shows that while the rate of decomposition increases for a brief period in response to warmer temperatures, elevated levels of decomposition don't persist. http://www.physorg.com/news144414973.html Space & Earth Tue, 28 Oct 2008 12:16:13 EST news144414973 Drawing on records dating back to the journals of Henry David Thoreau, scientists at Harvard University have found that different plant families near Walden Pond have borne the effects of climate change in strikingly different ways.
