Eric Rignot: On the Current State of Sea Level Rise Estimates (2019)

Glaciologist Eric Rignot (NASA/JPL) speaking at the American Philosophical Society meeting April 2019. Climate warming caused by human activities has woken up the sleeping ice giants in Greenland and Antarctica, elevating risks of multiple meters of sea level rise in the coming centuries. Rignot will discuss how satellites, airborne platforms, robotic devices and advanced numerical…

Video: Enhanced Seismic Activity Observed in Alaska Due To Climate Change

With news breaking that Alaska just had its warmest March to May on record with a statewide average temperature of 32.6°F, 8.6°F above the long-term average – the previous warmest spring in Alaska was in 2016, one must ask how this performs in relation to seismicity. Read the study excerpts of, Enhanced Seismic Activity Observed in Alaska Due…

Eric Rignot: Response of the Great Ice Sheets to Climate Warming (2014)

In 2014, as part of the Discover the Physical Sciences Breakfast Lecture Series at the University of California, climate researcher Eric Rignot (NASA/JPL) outlined our understanding of changes in the major cryosphere hotspots in Antarctica and Greenland, in his talk titled “Response of the Great Ice Sheets to Climate Warming”. Read about his newest 2019…

How burning Forests melt Ice Sheets

Forest fires can melt glaciers thousands of miles away by changing the colour of the ice – all thanks to a heavy little particle called black carbon. How burning Forests melt Ice Sheets How burning Forests melt Ice Sheets This strange story of smoke, dust and algae looks at the lesser-known half of a positive…

Did a Greenland Asteroid Cause Abrupt Warming Last Ice Age?

We report the discovery of a large impact crater beneath Hiawatha Glacier in northwest Greenland. From airborne radar surveys, we identify a 31-kilometer-wide, circular bedrock depression beneath up to a kilometer of ice http://advances.sciencemag.org/content/4/11/eaar8173 Hiawatha Glacier https://en.wikipedia.org/wiki/Hiawatha_Glacier Sources Discovering a massive meteorite crater https://www.youtube.com/watch?v=hQ9maLsIcts Massive crater under Greenland’s ice points to climate-altering impact in the…

Permafrost Melt Fires may Accelerate Greenland Melt

Dr. Nikolaos Evangeliou on climate change and wildfires (Oslo, August 2018). Evangeliou works at NILU – Norwegian Institute for Air Research http://nilu.no “If larger fires would burn, they would actually have a substantial impact on melting,” Stohl said. And, there’s a greater chance of such fires, if more of Greenland’s permafrost melts and exposes peat…

Can We Build a Giant Ocean Wall to Stop Sea Level Rise?

Is unavoidable sea level rise an engineering problem, do we have the capabilities for a technological fix? John C. Moore from the Arctic Centre of the University of Lapland presents these ideas in his October 2018 talk, “Stopping the flood – Can we engineer ice sheets and save the homes of a billion people?” Open…

ICE ALIVE – Documenting Life and Rapid Change

Joseph Cook is taking a closer look at the microbial life that can be found all over the planet’s glaciers and ice sheets. It is increasingly clear that this rich ecosystem affects the melt rates of polar ice and snow and could be accelerating climate change. Narrated by Jim Al-Khalili and starring Chris Hadfield. For…

How Greenland’s Melt Raises Seas. What will be left?

This video provides an outline on the accelerated ice loose from Greenland, explains the mechanism causing the melt, and features the new stunning visualization of Greenland without ice.

NASA’s Mission to Explore Greenland’s Ice Melt (Raw)

The Oceans Melting Greenland mission seeks to understand how ocean water is contributing to ice loss in Greenland. In October 2017, mission scientists and crew dropped 240 ocean probes from a C-130 aircraft into the waters around Greenland to measure ocean temperature. Footage includes interior and exterior shots of the aircraft with crew and scientists…

Experts: Permafrost + Gas Hydrates in Arctic, Greenland SLR, Security

In this panel, Vladimir Romanovsky (University of Alaska Fairbanks), talks about thawing permafrost. Anders Levermann (PIK) 12:30 ,talks about Greenland’s contribution to sea level rise, David Titley (Ret. U.S. Navy Admiral, now Pennsylvania State University) 23:38 , talks about security, with a subsequent panel discussion 33:34 . Video via Earth Institute https://www.youtube.com/watch?v=GFe3GOCBZO8

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…
