Researchers say regional surface temperatures can be affected by land use, suggesting that local and regional strategies, such as creating green spaces and buffer zones in and around urban areas, could be a tool in addressing climate change. A study by researchers from Purdue University and the universities of Colorado and Maryland concluded that greener land cover contributes to cooler temperatures, and almost any other change leads to warmer temperatures. The study, published on line and...

Most land-use changes occurring in the continental United States reduce vegetative cover and raise regional surface temperatures, says a new study by scientists at the University of Maryland, Purdue University, and the University of Colorado in Boulder. The study, which will appear in the Royal Meteorological Society's International Journal of Climatology, found that almost any change that makes land cover less "green" contributes to warming. However, a less intuitive finding is that...

The majestic snow-capped summits of Africa's Mount Kilimanjaro are melting quickly "” so quickly, in fact, that the ancient mountain's ice sheet could completely disappear within 20 years, says a US study released on Monday. In the study, published in the journal Proceedings of the National Academy of Sciences, climatologists reported that the ice cap crowning Kilimanjaro's peak shrank by some 85 in the nearly hundred years between 1912 and 2007.  Even more disturbing, ...

For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth's climate. And they've been aided by ever more sophisticated computer models that make estimating the relative impact of each type of pollutant more reliable. Yet the complexity of nature -- and the models used to quantify it -- continues to serve up surprises. The most recent? Certain gases that cause warming are so closely linked with the...

At an Oxford University climate conference, experts announced that sea levels across the globe will almost inevitably rise more than 6 feet. "The crux of the sea level issue is that it starts very slowly but once it gets going it is practically unstoppable," said Stefan Rahmstorf, a scientist at Germany's Potsdam Institute and a broadly respected sea level expert. "There is no way I can see to stop this rise, even if we have gone to zero emissions." According to Rahmstorf, the best outcome...

STOCKHOLM/>, September 23/> /PRNewswire/ -- New approaches are needed to help humanity deal with climate change and other global environmental threats that lie ahead in the 21st century. A group of 28 internationally renowned scientists propose that global biophysical boundaries, identified on the basis of the scientific understanding of the Earth System, can define a 'safe planetary operating space' that will allow humanity to continue to develop and thrive for generations to come....

U.S. space agency scientists say they've determined aerosols can influence climate by either reflecting or absorbing the sun's radiation in the atmosphere. National Aeronautics and Space Administration researchers said such aerosols -- tiny airborne particles -- enter the Earth's atmosphere from both natural and human sources such as industrial pollution, volcanoes and residential cook stoves. The scientists said much of the atmospheric warming observed in the Arctic since 1976 might be due...
