Melting mountain glaciers are contributing to sea-level rise faster than at any time in the last 350 years, according to new research published in Nature Geoscience.
A research team from the University of Exeter, Aberystwyth University, and Stockholm University undertook a survey of the 270 largest outlet glaciers of the South and North Patagonian Icefields of South America. (more…)
Warmer air is only part of the story when it comes to Greenland’s rapidly melting ice sheet. New research by scientists at Woods Hole Oceanographic Institution (WHOI) highlights the role ocean circulation plays in transporting heat to glaciers.
Greenland’s ice sheet has lost mass at an accelerated rate over the last decade, dumping more ice and fresh water into the ocean. Between 2001 and 2005, Helheim Glacier, a large glacier on Greenland’s southeast coast, retreated 5 miles (8 kilometers) and its flow speed nearly doubled. (more…)
Many coastal wetlands worldwide — including several on the U.S. Atlantic coast — may be more sensitive than previously thought to climate change and sea-level rise projections for the 21st century. (more…)
ANN ARBOR, Mich.— In an effort to understand how fast sea level could rise as the climate warms, a University of Michigan researcher has developed a new theory to describe how icebergs detach from ice sheets and glaciers.
This process of “iceberg calving” isn’t well understood. While scientists believe it currently accounts for roughly half of the mass lost in shrinking ice sheets, current sea level rise models don’t take changes in iceberg calving into account in their predictions, says Jeremy Bassis, an assistant professor in the Department of Atmospheric, Oceanic and Space Sciences.
