Weather forecasters may soon be able to predict deadly flash floods several days in advance using a new technique developed by Penn State researchers and the National Weather Service. (Penn State Release)

A new study concludes that huge reductions in fossil-fuel carbon emissions will be required by the middle of this century -- regardless of the likely climate sensitivity. (U.S. Department of Energy)

Scientists at the National Center for Atmospheric Research (NCAR) and colleagues at universities and NASA have clarified the process by which ozone--an essential shield in the stratosphere, but a pollutant at lower levels--reaches its peak abundance across North America each spring.

A new study suggests natural fire regimes, such as those found in southern California, are "more driven by extreme weather conditions" than age-related traits of the region's plant life. (Ecological Society of America press release)

Global warming and the partial melting of polar ice sheets can dramatically affect not only sea levels but also Earth's climate, in ways that may be complex, rapid and difficult to adjust to, scientists say in a new study to be published Friday in the journal Science. (Oregon State University)

Thanks to recent measurement corrections made possible by a NIST device called SIRCUS, the Earth's oceans may look a bit bluer than they did before in satellite images -- meaning there may be less carbon in the oceans and more in the atmosphere than previously thought. (National Institute of Standards and Technology)

Cloudy weather may dampen the human spirit, but it also may dampen the effects of global warming on the Arctic, according to new study published in the March 14 issue of the journal Science. (University of Wisconsin-Madison)
