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)
Global warming: Our best guess is likely wrong
No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study this week suggests scientists' best predictions about global warming might be incorrect. view more (2009-07-15)
Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science. view more (2007-06-25)
More fires, droughts and floods predicted
As temperatures rise with global warming, an increased risk of forest fires, droughts and flooding is predicted for the next 200 years by climate scientists from the University of Bristol, UK. view more (2006-08-15)
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)
Global sunscreen won't save corals
Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life. view more (2009-06-17)
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)
Trees to offset the carbon footprint?
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming. view more (2007-04-10)
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)
Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences. view more (2008-10-06)
Temperate Forests Could Worsen Global Warming
Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. view more (2005-12-07)
Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the rate of global warming to increase further. view more (2006-03-09)
Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon dioxide was in the air at various periods during... view more... (2002-09-12)
Global warming predicted to hasten carbon release from peat bogs
Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change. view more (2008-11-07)
Global warming will reduce ocean productivity, marine life
A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans-the growth of phytoplankton that forms the basis for the rest of the marine food chain-is tightly linked to climate change, and would be reduced by global warming. view more (2006-12-07)
Global warming aided by drought, deforestation link
In the rainforests of equatorial Asia, a link between drought and deforestation is fueling global warming, finds an international study that includes a UC Irvine scientist. view more (2008-12-09)
How the atmospheres of Mars and Venus are affected by carbon monoxide
Modelling of the Earth's atmosphere has acquired economic importance due to its use in the prediction of ozone depletion and in measuring the impact of global warming. view more (2008-02-26)
Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will... view more... (2005-05-05)
Americans consider global warming an urgent threat, according to poll
A growing number of Americans consider global warming an important threat that calls for drastic action, and 40% say that a presidential candidate's position on the issue will strongly influence how they vote, according to a national survey conducted by Yale University, Gallup and the ClearVision Institute. view more (2007-10-02)
New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate. view more (2007-12-12)
