NASA Laser Reveals Miles of Greenland Ice Loss

What if you could measure a glacier in such detail that you could visualize its surface in 3D? And what if you could compare that view with data from one, two, even 20 years ago? NASA airborne campaigns like Operation IceBridge have been measuring Greenland and Antarctica’s glaciers and ice sheets with a range of…

Little Algae creates Huge Melt Feedback on Greenland Ice

Algae responsible for large albedo feedback on Greenland’s frozen surface, not only soot and dust. We believe gathering measurements from the surface of Greenland ice is fundamental to advancing our understanding of the melting Arctic. http://darksnowproject.org Video via https://www.youtube.com/user/greenman3610 Dark Snow 2017 Update “Am I really seeing that?” is a common sensation here, as below,…

Konrad Steffen: The Melting of Greenland (March 2017)

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…

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…

Greenland Melt contributes to Sea Level Rise

Using satellite and field work after an extreme melt event in Greenland, a UCLA-led study finds that melt-prone areas on its ice sheet develop a remarkably efficient drainage system of stunning blue streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. However, the team’s measurements at the ice’s edge show that…

Potential abrupt cataclysmic change and the Atlantic

A slowdown or even collapse of the Gulf Stream System as a result of global warming has long been a concern of climate scientists and has fuelled the imagination of Hollywood. Recent studies provide evidence for a AMOC slowdown.

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…

NASA: Zachariæ Isstrøm Glacier Greenland entered accellerated retreat

NASA: Zachariæ Isstrøm has become the latest Greenland glacier to undergo rapid changes in a warming world. Research published November 2015 in Science found that Zachariæ Isstrøm broke loose from a stable position in 2012 and entered a phase of accelerated retreat. The consequences will be felt for decades to come. The reason? Zachariæ Isstrøm is…

NASA State of Sea Level Rise Science 2015 – 30 feet of SLR possible by 2100

Excerpt from https://www.youtube.com/watch?v=vDdNxb2xVBU Members of NASA’s new interdisciplinary Sea Level Change Team discussed recent findings and new agency research efforts during a media teleconference Aug. 26, 2015, at 12:30 p.m. EDT. The panelists for this briefing were: — Michael Freilich, director of NASA’s Earth Science Division at the agency’s headquarters in Washington — Steve Nerem,…

NASA Rising Seas: The State of the Greenland Ice Sheet (2015)

Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of…

The Hidden Meltdown of Greenland!

Aug. 28, 2015: More than 90 percent of our planet’s freshwater ice is bound in the massive ice sheets and glaciers of the Antarctic and Greenland. As temperatures around the world slowly climb, melt waters from these vast stores of ice add to rising sea levels. All by itself, Greenland could bump sea levels by…
