Greenlands Ice Melt Breaks Record, Starting Nearly Two Months Early
2016-04-13 15:51:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Greenlands melt season kicked off a month and a half early this year, scientists at the Danish Meteorological Institute (DMI) reported. Greenlands melt season typically runs from June until September, but almost 12 percent of Greenlands ice sheet was melting as of Monday, which scientists say is unprecedented. We had to check that our models were still working properly, said Peter Langen, a climate scientist at DMI. Areas of Greenland recorded temperatures this month that would have...

Summer melt-driven streams on Greenland's ice sheet brought into focus
2016-04-07 01:05:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Erosion by summertime melt-driven streams on Greenland's ice sheet shapes landscapes similarly to, but much faster than, rivers do on land, says a University of Oregon geologist. The approach used to study the ice sheet should help to broaden scientific understanding of melt rates and improve projections about glacial response to climate change, says Leif Karlstrom, a professor in the UO Department of Geological Sciences. The study, online ahead of print in the journal Geophysical Research Letters,...

Greenland's ice is getting darker, increasing risk of melting
2016-03-03 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface's reflectivity, or albedo, decreasing by as much as 10 percent by the end of the century, the study says. While soot blowing in from wildfires contributes to the problem, it hasn't been driving the change, the study finds. The real culprits are two feedback loops created by the...

Greenland's ice melt accelerating as surface darkens, raising sea levels
2016-03-03 19:35:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Greenlands vast ice sheet is in the grip of a dramatic feedback loop where the surface has been getting darker and less reflective of the sun, helping accelerate the melting of ice and fuelling sea level rises, new research has found. The snowy surface of Greenland started becoming significantly less reflective of solar radiation from around 1996, the analysis found, with the ice absorbing 2% more solar energy per decade from this point. At the same time, summer near-surface temperatures in...
Greenland's glaciers through an artist's eyes - in pictures
2016-02-25 13:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: In September 2015, artist Mariele Neudecker and photographer Klaus Thymann embarked on a joint project to detail the glaciers of Narsarsuaq, south-west Greenland. The collaboration is part of a mission by UK charity Project Pressure to record the worlds vanishing and receding glaciers using art as inspiration
