Soot darkens snow and ice, increasing solar energy absorption, hastening the melt of the cryosphere." [1] The soot comes in part from wildfires, of which there were many in 2012. Also in 2012, almost all of the surface of Greenland was observed to be melting. [9] The increase in size of the wildfires may itself be a result of global warming. [5]
This narrated animation shows the overall change in the elevation of the Greenland ice sheet between 2003 and 2012. The coastal areas of the ice sheet lost far more height, or "thinned", compared to the more inland regions. Greenland ice sheet has 215 marine-terminating glaciers whose retreat directly impacts sea level rise.
The worst-case scenarios predicted by experts studying Greenland’s ice melt are being outpaced by what’s actually happening, a new study has found. A review of historical data on how glaciers ...
Greenland's ice melt is of particular concern, as the ancient ice sheet holds enough water to raise sea levels by at least 20 feet (6 meters) if it were to melt away entirely. A study of a ...
Satellite observations have revealed the Greenland ice sheet’s rapid thinning, which has accelerated as the planet warms Incredible satellite images show Greenland’s massive ice sheet melting ...
In the Arctic, the main human-influenced sources of methane are thawing permafrost, Arctic sea ice melting, clathrate breakdown and Greenland ice sheet melting. This methane release results in a positive climate change feedback (meaning one that amplifies warming), as methane is a powerful greenhouse gas. [3]
The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick and over 3 km (1.9 mi) thick at its maximum. [ 57 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N ...
New research suggests the Greenland ice sheet is on track to cross a critical threshold that could cause runaway melting, but that it’s also possible the threshold will be crossed temporarily ...
