Greenland Ice Sheet Movement Decreasing Despite Warming
A newly published study from the University of Edinburgh shows that the movement of the southwest portion of the Greenland Ice Sheet that terminates on land has been slowing down despite decades of increasing temperatures and surface melting.
Researchers derived their results by tracking ice sheet movement through Landsat satellite images taken from 1985 to 2014 across a roughly 3,088-square-mile (8000-square-kilometer) region in southwest Greenland.
The finding is contrary to the widely held view that a greater amount of surface melting will result in faster-moving ice sheets, as the movement of both ocean- and land-terminating ice sheets is caused in part by surface meltwater, which makes its way to the bedrock through openings in the ice and acts as a lubricant.
Reigning Wimbledon champions Sania Mirza and Martina Hingis earned their third consecutive win to top the red group and enter the semifinals of the year-ending $7 million WTA Finals being played at the Singapore Indoor Stadium.
Following their victories in the opening two round robin matches earlier this week, the Indo-Swiss tennis combine came up with another top-class performance to beat Hungarian-French fourth seeds Tímea Babos and Kristina Mladenovic 6-4, 7-5 in one and a half hours.
