A top climate specialist with the Intergovernmental Panel on Climate Change said Tuesday that despite variations in predictions of climate change trends, Europe should take action over the increase in droughts and floods across the union. "There are some robust areas like Siberia, we know what the climate will be, another robust area is the Mediterranean, because the models tell the same story," said Zbigniew Kundzewicz, review editor of IPCC's chapter on freshwater resources. "Climate...

Study Shows Daily Malleability on a Long-Term Question Social scientists are struggling with a perplexing earth-science question: as the power of evidence showing manmade global warming is rising, why do opinion polls suggest public belief in the findings is wavering? Part of the answer may be that some people are too easily swayed by the easiest, most irrational piece of evidence at hand: their own estimation of the day's temperature. In three separate studies, researchers affiliated with...

Recent climate modeling has shown that reducing the concentration of carbon dioxide in the atmosphere would give the Earth a wetter climate in the short term. New research from Carnegie Global Ecology scientists Long Cao and Ken Caldeira offers a novel explanation for why climates are wetter when atmospheric carbon dioxide (CO2) concentrations are decreasing. Their findings, published online today by Geophysical Research Letters, show that cutting carbon dioxide concentrations could help...

The deadly heat wave that crippled Russia last summer was due to a natural atmospheric phenomenon often associated with weather extremes and not directly caused by global warming, according to a new study by the National Oceanic and Atmospheric Association (NOAA). And while the scientists could not attribute the intensity of the Russian heat wave to climate change, they did find that extreme heat waves are likely to become more frequent in the region in the coming decades. The researchers...

New University of Washington research has found that the world is already committed to a warmer climate because of emissions that have occurred up to now. The researchers said that there would continue to be warming even if the most stringent policies were adopted because there would still be some emissions of heat-trapping greenhouse gases like carbon dioxide and methane. The team found that even if all emissions were stopped now, temperatures would remain higher than pre-industrial...

The Roman Conquest, the Black Death and the discovery of America "“ by modifying the nature of the forests "“ have had a significant impact on the environment. These are the findings of EPFL scientists who have researched our long history of emitting carbon into the environment. "Humans didn't wait for the industrial revolution to provoke environment and climate change. They have been having an influence for at least 8000 years." Jed Kaplan is putting forward a new interpretation...

Written by Earle Holland, Ohio State University One of the world's foremost experts on climate change is warning that if humans don't moderate their use of fossil fuels, there is a real possibility that we will face the environmental, societal and economic consequences of climate change faster than we can adapt to them. Lonnie Thompson, distinguished university professor in the School of Earth Sciences at Ohio State University, posed that possibility in a just-released special climate-change...

CANCUN, Mexico, Dec. 6, 2010 /PRNewswire-USNewswire/ -- Nearly all those gathered for the United Nations Climate Change Conference in Cancun believe that real international action on climate change will not happen without strong public support, yet most also believe that the general public doesn't understand the meaning of "climate change," according to a survey this week by the Government of Mexico and the Pew Center on Global Climate Change. More than 500 accredited COP16/CMP6 attendees...

Representatives from 194 countries have gathered at the 2010 UN Climate Change Conference in Cancun, Mexico, to continue working towards tackling climate change. ESA is attending 'COP16' to update negotiators on satellite observations of climate, and to explain how the ESA Climate Change Initiative (CCI) will provide consistent data to help scientists better understand climate change. Our climate is a complex system made up of many different parts, all interacting together. No one part can be...
