What’s Happening to the Greenland Ice Sheet? (October 2017)

The Greenland ice sheet is one of the largest contributors to global sea level rise, and if completely melted, could add ~7 meters to sea level. In recent years, the imbalance of the ice sheet has increased with warmer atmospheric conditions. In this talk, Visiting Assistant Professor Samiah Moustafa describes the field’s current knowledge on…

Largest Glacier East Antarctic may add to Sea Level Rise (Totten Glacier)

Totten Glacier, the largest glacier in East Antarctica, is being melted from below by warm water that reaches the ice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice…

Scientist Explains Climate Ice Core Proxies (2017)

This talk by Lonnie G. Thompson, focuses on glaciers as recorders and early indicators of climate change. The ongoing widespread melting of high-elevation glaciers and ice caps, particularly in low to middle latitudes, provides strong evidence that a large scale, pervasive and in some cases, rapid change in Earth’s climate system is underway. On Thursday…

Antarctic Volcanoes Waking up?

Nearly 100 Volcanoes Discovered Beneath Antarctica’s Ice http://blogs.discovermagazine.com/d-brief/2017/08/14/volcanoes-under-antarctica A new volcanic province: an inventory of subglacial volcanoes in West Antarctica http://www.geos.ed.ac.uk/homes/rbingha2/48_2017_Vries.pdf Scientists discover 91 volcanoes below Antarctic ice sheet This is in addition to 47 already known about and eruption would melt more ice in region affected by climate change https://www.theguardian.com/world/2017/aug/12/scientists-discover-91-volcanos-antarctica How a melting ice…

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,…

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…

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…
