Experts Calculate Future Ice Loss and Sea-Level Increases From Greenland and Antarctica
Ice-sheet models are an essential tool in making predictions regarding the future of the Greenland and Antarctic Ice Sheets. Nevertheless, these models still have a…
Spalte Glacier Has Disintegrated: A Segment of the Largest Arctic Ice Shelf Shattered Into a Flotilla of Small Icebergs
This series of four Copernicus Sentinel-2 images captured between June 29 and July 24, 2020, shows a segment of the largest ice shelf in the…
More, Longer, Hotter: California Heatwave Fits a Trend
In early September 2020, an intense heatwave broke temperature records in several locations in Southern California. The dry, hot conditions helped fuel new and existing…
Global Warming Could Cause Viruses to Evolve, Making Them Harder to Kill
Enteroviruses and other pathogenic viruses that make their way into surface waters can be inactivated by heat, sunshine and other microbes, thereby reducing their ability…
Global Warming Warning: Devastating Hurricanes Could Be Up to Five Times More Likely in the Caribbean
Global warming is dramatically increasing the risk of extreme hurricanes in the Caribbean, but meeting more ambitious climate change goals could up to halve the…
“Worst-Case Climate Scenario” – Ice Sheets in Greenland and Antarctica Loss Rates Rapidly Increasing
A recent report confirms that ice sheets in Greenland and Antarctica, whose mass-loss rates have been rapidly increasing, are matching the Intergovernmental Panel on Climate…
