Greenland ice sheet melts more when it’s cloudy

Clouds play a bigger role in the melting of the Greenland ice sheet than was previously assumed. Compared to clear skies, clouds enhance the meltwater runoff by a third. Those are the findings of an international study that was coordinated by KU Leuven and published in Nature Communications. Greenland’s ice sheet is the second largest ice mass in the world …

Climate change altering Greenland ice sheet and accelerating sea level rise, says York University professor

TORONTO, January 4, 2016 – The Greenland ice sheet has traditionally been pictured as a bit of a sponge for glacier meltwater, but new research has found it is rapidly losing the ability to buffer its contribution to rising sea levels, says a York University researcher. York U Professor William Colgan, a co-author on the study published today in the …

Andrea Germanos – NASA: World ‘Locked Into’ at Least 3 Feet of Sea Level Rise

New research underway indicates that at least three feet of global sea level rise is near certain, NASA scientists warned Wednesday. That’s the higher range of the 1 to 3 feet level of rise the UN Intergovernmental Panel on Climate Change (IPCC) gave in itsĀ 2013 assessment. Sea levels have already risen 3 inches on average since 1992, with some areas …

We May Have Already Committed Ourselves to 6-Meter Sea-Level Rise – Pete Dolack

Even if humanity were to stop throwing carbon dioxide and methane into the atmosphere today, a catastrophic rise in sea levels of six meters may be inevitable. Two previous prehistoric interglacial periods, in which the carbon dioxide content of the atmosphere was believed to be about what it is today, resulted in dramatic rising of the oceans. High-latitude ice sheets …

Methane Outbreak Nears by ROBERT HUNZIKER

The Intergovernmental Panel on Climate Change (IPCC) as well as world governments ignores the risks of an ice-free Arctic (Wadhams). Rather, an ice-free Arctic is widely applauded by much of the world as a positive way forward for re-opening of northern shipping routes, new trips for cruise lines, and access to a huge cache of fossil fuels. According to Professor …
