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…

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…
