NASA Discovers a New Mode of Ice Loss in Greenland (Solitary Wave)

A new NASA study finds that during Greenland’s hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island’s west coast didn’t just melt faster than usual, it slid through the glacier’s interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing. https://www.jpl.nasa.gov/news/news.php?feature=6857 “You could…

NASA: Greenland ice loss 2002-2016

The mass of the Greenland ice sheet has rapidly declined in the last several years due to surface melting and iceberg calving. Research based on observations from the NASA/German Aerospace Center’s twin Gravity Recovery and Climate Experiment (GRACE) satellites indicates that between 2002 and 2016, Greenland shed approximately 280 gigatons of ice per year, causing…

NASA: Antarctic Ice Loss 2002-2016

The mass of the Antarctic ice sheet has changed over the last several years. Research based on observations from NASA’s twin NASA/German Aerospace Center’s twin Gravity Recovery and Climate Experiment (GRACE) satellites indicates that between 2002 and 2016, Antarctica shed approximately 125 gigatons of ice per year, causing global sea level to rise by 0.35…

Scientists monitoring the Greenland Ice Sheet (PROMICE 2017)

In 2007, Denmark launched the Programme for Monitoring of the Greenland Ice Sheet (PROMICE) to assess changes in the mass balance of the ice sheet. This video presented by Geocenter Denmark gives us a 2017 update. For more visit http://undergroundchannel.dk and http://promice.org The continuous monitoring of the ice sheet makes PROMICE a unique and important…

Expert explains Future Sea Level Rise (2017)

Eric Rignot (NASA/JPL) one of the world’s most prominent glaciologists, who is behind a landmark report revealing the unstoppable collapse of a large part of Antarctica, gave a lecture at Victoria University of Wellington in February 2017, on future sea level rise. Future sea-level rise from warming of polar ice sheets http://www.victoria.ac.nz/news/2017/02/future-sea-level-rise-from-warming-of-polar-ice-sheets This video has…

Study: Contribution of Antarctica to past and future sea-level rise (2016)

A study published in March 2016, suggests that large parts of East Antarctica’s ice sheet can collapse, can do so under Pliocene conditions. A key question has long been whether ice sheet contribution could accelerate substantially, by an order of magnitude, either in this century or subsequently. Until recently ice sheet models had problems to…

Ice sheet deglaciation and methane emissions, with the scope on Greenland’s melt season

On June 9 2016, Nuuk, the capital of Greenland, reached the warmest temperature ever recorded for the month of June anywhere on the island, 24 degrees Celsius (75 degrees Fahrenheit). An article from NSDIC, published June 22 elaborated on the broader situation: Surface melting on Greenland’s Ice Sheet proceeded at a brisk pace, with three…

Ice sheets may be hiding vast reservoirs of methane

The study indicates that under the frigid weight of Barents Sea Ice sheet, which covered northern Eurasia some 22 000 years ago, significant amounts of methane may have been stored as hydrates in the ground. As the ice sheet retreated, the methane rich hydrates melted, releasing the climate gas into the ocean and atmosphere for…

AGU 2015: Eric Rignot – Ice Sheet Systems and Sea Level Change

Scientific Discipline Cryosphere Speaker Eric Rignot (NASA Jet Propulsion Laboratory) Abstract Modern views of ice sheets provided by satellites, airborne surveys, in situ data and paleoclimate records while transformative of glaciology have not fundamentally changed concerns about ice sheet stability and collapse that emerged in the 1970’s. Motivated by the desire to learn more about…
