A switch from predominantly undersea volcanoes to a mix of undersea and terrestrial ones shifted the Earth's atmosphere from devoid of oxygen to one with free oxygen, according to geologists. (Pennsylvania State University press release)
Greenhouse gases likely accounted for more than half of the widespread warmth across the continental United States last year, according to a new study. (NOAA press release)
Hot spots across Southeastern Europe Aug. 21-26 have been detected with instruments aboard European Space Agency satellites, which have been continuously surveying fires burning across the Earth's surface for a decade. (European Space Agency press release)

New research to test global ice volume approximately 41.6 million years ago shows that ice caps at this time, if they existed at all, would have been small and easily accommodated on Antarctica. (Joint Oceanographic Institutions press release)
A new lab is the first of its kind to tackle the global problem of climate change impacts on corals, and will be used to study how corals respond to the combined stress of greenhouse warming and ocean acidification. (University of Miami press release)
Scientists have verified the accuracy of a model that uses October snow cover in Siberia to predict upcoming winter temperatures and snowfall for the high- and mid-latitudes of the Northern Hemisphere. (National Science Foundation press release)
Researchers are now forecasting a 92 percent chance that the 2007 September minimum extent of sea ice across the Arctic region will set an all-time record low. (University of Colorado at Boulder press release)
Expansion of irrigation has masked greenhouse warming in California�s Central Valley, but irrigation may not make much of a difference in the future, according to a new study. (National Science Foundation press release)
Rising atmospheric temperatures are accelerating rates of permafrost thaw in northern regions, which can have complex impacts on greenhouse gas fluxes from wetlands in the area. (Michigan State University)
Corals in the central and western Pacific ocean are dying faster than previously thought, researchers have found. (University of North Carolina at Chapel Hill press release)
Zambian water authorities are integrating information based on satellite imagery to alleviate water shortages. (European Space Agency press release)
As catastrophic floods worsen in Bangladesh, a pilot forecasting program is being used to warn thousands of residents in selected flood-prone regions. (University Corporation for Atmospheric Research press release)
A reversal of tectonic plate motion between Acapulco and Mexico City in the last half of 2006 probably didn�t ease seismic strain in the region or the specter of a major earthquake anticipated there in the coming decades, researchers suggest. (University of Colorado at Boulder press release)
August 1- The combined heating effect of greenhouse gases and brown clouds is enough to account for the retreat of Himalayan glaciers observed in the past half century, which supply water to major Asian rivers. (University of California, San Diego press release)
Tremors rippled the landscape of Vancouver Island, the westernmost part of British Columbia, during a major Alaskan earthquake and geoscientists have found clear evidence that the two events were related. (University of Washington press release)
