Greenland glacial melt is growing factor rising sea levels

Al Jazeera: Greenlands glaciers are far more vulnerable to climate change-induced warming oceans than previously thought, a report released Sunday by UC- Irvine and NASA glaciologists said. The study, published in the journal Nature Geoscience, reveals previously uncharted deep valleys stretching for dozens of miles under the Greenland Ice Sheet -- showing that there are no natural barriers to stop the melting. The findings echo a report released last week showing that glacial melting in West Antarctica...

Greenland melting due equally to global warming, natural variation
2014-05-08 01:17:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The rapid melting of Greenland glaciers is captured in the documentary "Chasing Ice." The retreat of the ice edge from one year to the next sends more water into the sea. Now University of Washington atmospheric scientists have estimated that up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable...

New data on what Greenland was like almost 3 million years ago

Environmental News Network: Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything vegetation, soil and even the top layer of bedrock. So a team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice. "We found organic soil that has been frozen to the bottom of the ice sheet for 2.7 million years," said University of Vermont geologist...
Ancient Landscape Is Found Under 2 Miles Of Ice In Greenland

National Public Radio: In a surprising discovery, scientists have found evidence of a tundra landscape in Greenland that's millions of years old. The revelation goes against widely held ideas about how some glaciers work, and it suggests that at least parts of Greenland's ice sheet had survived periods of global warming intact. "Glaciers are commonly thought to work like a belt sander," a news release from the University of Vermont says. "As they move over the land they scrape off everything - vegetation, soil, and...

Greenland: Chasing Ice movie reveals largest iceberg break-up ever filmed
2014-04-18 06:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: It's like watching 'Manhattan breaking apart in front of your eyes', says one of the researchers for filmmaker James Balog. He's describing the largest iceberg calving ever filmed, as featured in his movie, Chasing Ice. After weeks of waiting, the filmakers witnessed 7.4 cubic km of ice crashing off the Ilulissat glacier in Greenland. Chasing Ice, released in the UK on Friday, follows Balog's mission to document Arctic ice being melted by climate change. Watch our second clip from the documentary...
