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…
Volcanism triggered by deglacial unloading may plausibly accelerate melting and water runoff through an albedo effect of dark tephra on snow and ice. http://www.sciencedirect.com/science/article/pii/S0012821X16303892
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.

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…
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…
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…
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…

Recently, James Hansen the former director of NASA GISS published new study findings about future sea level rise, ice melt, and temperature changes, as well as the possible implications for future climate. Above video highlights a part of a talk Hansen held on December 1, 2015 at the Paris climate change conference (COP21). The take…
