Greenland is melting way ahead of schedule

2016-04-13 23:36:00| Climate Ark Climate Change & Global Warming Newsfeed

Grist: To say the 2016 Greenland melt season is off to the races is an understatement. Warm, wet conditions rapidly kicked off the melt season this weekend, more than a month-and-a-half ahead of schedule. It has easily set a record for earliest melt season onset, and marks the first time its begun in April. Little to no melt through winter is the norm as sub-zero temperatures keep Greenlands massive ice sheet, well, on ice. Warm weather usually kicks off the melt season in late May or early June, but...

Antarctic Melting Could Double Sea-Level Rise

2016-04-12 14:59:00| Climate Ark Climate Change & Global Warming Newsfeed

CourtHouse News: Scientists have underestimated the impact of Antarctic ice-sheet melting on global sea levels, which one group of researchers now believe may rise 50 feet in the next 500 years if greenhouse gas emissions continue. The massive West Antarctic ice sheet - one of the final leftovers from the last ice age - is larger than Mexico, and capable of raising global sea level by 12 feet or more due to its significant width and depth. While scientists had presumed that it would take hundreds of years for...

The terrifying math of melting ice sheets

2016-04-10 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Living On Earth: Recent studies of the physics of ice sheets suggests that we may be vastly underestimating how fast the West Antarctic ice sheet is melting because of global warming. Penn State Climate Scientist Michael Mann tells host Steve Curwood that combined with the melting from other glaciers around the world, seas could rise over six feet by 2100, putting many coastal cities underwater. Transcript CURWOOD: From the Jennifer and Ted Stanley studios at the University of Massachusetts Boston and PRI,...

Greenland and Antarctic melting isnt just raising seas its changing the Earths rotation

2016-04-09 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Washington Post: Africa is front and center in this image of Earth taken in July 2015 by a NASA camera on the Deep Space Climate Observatory (DSCOVR) satellite. Sophisticated new gravity research suggests that changes in Earths climate may actually be having a stunning geophysical effect: slightly moving the location of the planets spin axis, or axis of daily rotation. In other words, even as the Earth spins on its axis in a west to east direction, completing a full rotation every 24 hours, that axis itself...

How melting ice sheets are changing the way the Earth moves on its axis video explainer

2016-04-09 13:31:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: Global warming is changing the way the Earth moves on its polar axis. A new Nasa study says that Melting ice sheets are affecting the distribution of weight on Earth, which is causing both the North Pole and the wobble, which is called polar motion, to change course. Scientists say the polar motion shift is harmless, but that it highlights the impact humans are having on the planet
