Greenland may be losing ice even faster than we thought

Washington Post: Rapidly melting Greenland may be shedding its ice even faster than anyone suspected, new research suggests. A study just out in the journal Science Advances finds that previous studies may have underestimated the current rate of mass loss on the Greenland ice sheet by about 20 billion tons per year. Generally, scientists estimate ice loss in Greenland (and elsewhere around the world) using data from satellites. But the new study suggests these satellite studies may have included some incorrect...

Global warming: Greenland ice melting 7 per cent faster than thought

2016-09-22 06:22:00| Climate Ark Climate Change & Global Warming Newsfeed

Press Trust of India: Greenland lost nearly 2,700 gigatonnes of ice from 2003-2013, 7.6 per cent more than previously thought, a new study has found. According to researchers from Ohio State University in the US, the hotspot that feeds Icelands active volcanoes has softened the mantle rock beneath Greenland in a way that ultimately distorted their calculations for ice loss in the Greenland ice sheet. This caused them to underestimate the melting by about 20 billion metric tonnes or 20 gigatonnes per year. That means...

IBMs new AI-friendly server adopts Nvidias NVLink for faster memory

2016-09-08 19:30:32| Extremetech

Everyone expects GPUs like Nvidia's Tesla P100 in purpose-built AI servers, but optimizing memory access is also a major issue. IBM is using Nvidia's NVLink to help with that bottleneck.
