  • New Tool May Assist US Regional Sea Level Planning May 5, 2017 Thanks in large part to satellite measurements, scientists’ skill in measuring how much sea levels are rising on a global scale – currently 0.13 inch (3.4 millimeters) per year – has improved dramatically over the past quarter century. But at the local level, it’s been harder to estimate specific regional sea level changes 10 or ...
  • Scientists Map Movement of Greenland Ice During Past 9,000 Years February 10, 2016 Scientists have created the first map that shows how the Greenland Ice Sheet has moved over time, revealing that ice in the interior is moving more slowly toward the edges than it has, on average, during the past 9,000 years. The findings, which researchers said don’t change the fact that the ice sheet is losing mass ...
