Researchers documented changes in the lengths of more than 1,000 of Greenland’s glaciers over the past 130 years. The study finds that climate change explains the accelerated glacier retreat and that glaciers across the country respond quickly to changing temperatures, which highlights the importance of slowing global warming.

Greenland’s glacier retreat rate has doubled over past two decades

The new findings are ubiquitous, even among Earth’s northernmost glaciers Greenland’s thousands of peripheral glaciers have entered a new and widespread state of rapid retreat, a Northwestern University and University of Copenhagen study has found. To piece together the magnitude of glacier...

Ancient plant wax reveals how global warming affects methane in Arctic lakes

Warming led to an intensified methane cycle, lasting thousands of years, study finds By studying fossils from ancient aquatic plants, Northwestern University and University of Wyoming (UW) researchers are gaining a better understanding of how methane produced in Arctic lakes might...
