Making predictions about climate variability often means looking to the past to find trends. Now paleoclimate researchers from the University of Missouri have found clues in exposed bedrock alongside an Alabama highway that could help forecast climate variability. In their study, the researchers verified evidence suggesting carbon dioxide decreased significantly at the end of the Ordovician Period, 450 million years ago, preceding an ice age and eventual mass extinction. These results will help climatologists better predict future environmental changes
Pioneering new research sheds light on the impact of climate change on subglacial lakes found under the Greenland ice sheet.
A mysterious kidney disease that has killed over 20,000 people in Central America, most of them sugar cane workers, may be caused by chronic, severe dehydration linked to global climate change, according to a new study by Richard J. Johnson, MD, of the University of Colorado Anschutz Medical Campus.
As record ocean temperatures cause widespread coral bleaching across Hawaii, NOAA scientists confirm the same stressful conditions are expanding to the Caribbean and may last into the new year, prompting the declaration of the third global coral bleaching event ever on record.
In a previous life, Jo-Kristian Røttereng walked the rainforests of the Congo Basin, as a part of the Norwegian government’s NOK 3 billion effort to curb tropical deforestation. He’s seen the towering trees, heard the grunting of gorillas from deep in the jungle, watched brightly coloured birds flit through sunlight filtered through the thick forest canopy.
In the most authoritative forum yet held on the role of the polar regions in global climate change, the American Polar Society (APS), the 80-year-old organization linking scientists, explorers, and enthusiasts with deep interest in polar issues, and Scripps Institution of Oceanography at UC San Diego, are jointly bringing together world-class leaders in science and diplomacy in a symposium to review the latest findings from research on the impact of rising global temperatures on sea and land ice and their ecosystems at the top and bottom of the world.
New research shows that butterflies in Greenland have become smaller in response to increasing temperatures due to climate change.
The history of wildfires over the past 2,000 years in a northern Colorado mountain range indicates that large fires will continue to increase as a result of a warming climate, according to new study led by a University of Wyoming doctoral student.
The more ice is melted of the Antarctic Filchner-Ronne shelf, the more ice flows into the ocean and the more the region contributes to global sea-level rise. While this might seem obvious, it is no matter of course for the huge ice masses of Antarctica: parts of the ice continent are characterized by instabilities that, once triggered, can lead to persistent ice discharge into the ocean even without a further increase of warming - resulting in unstoppable long-term sea-level rise.
International climate agreements like the Kyoto Protocol may discourage much-needed investment in renewable energy sources, and hence be counterprodutive, according to new research.
