Ancient catastrophic drought leads to question: How severe can climate change become?
How severe can climate change become in a warming world?
Worse than anything we’ve seen in written history, according to results of a study appearing this week in the journal Science.
An international team of scientists led by Curt Stager of…
Climate projections show human health impacts possible within 30 years
A panel of scientists speaking today at the annual meeting of the American Association for the Advancement of Science (AAAS) unveiled new research and models demonstrating how climate change could increase exposure and risk of human illness originat…
Climate change to continue to year 3000 in best case scenarios
New research indicates the impact of rising CO2 levels in the Earth’s atmosphere will cause unstoppable effects to the climate for at least the next 1000 years, causing researchers to estimate a collapse of the West Antarctic ice sheet by the year 3…

Climate change implicated in decline of horseshoe crabs
LEETOWN, W. Va. — A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes.

Springtime Temperature Swings Attack Northeastern Forests
Forest dieback in the northeastern United States and neighboring areas in Canada has been more frequent, more persistent, and more severe during recent decades, research has shown. Now scientists have found springtime temperature swings have intensified in that region during the same period. A new study links these escalating freeze-thaw episodes, which are known to harm trees, to an atmospheric pressure imbalance over the North Atlantic.
Researchers Say Tiny Phytoplankton Plays Large Role in Earth’s Climate
The ecological importance of phytoplankton, microscopic plants that free-float through the world’s oceans, is well known. Among their key roles, the one-celled organisms are the major source of sustenance for animal life in the seas. Now, researchers at Scripps Institution of Oceanography in San Diego say that phytoplankton exert a significant and previously uncalculated influence on Earth’s climate.
