We interviewed Eric Rignot, Donald Bren Professor and Chancellor Professor of Earth system science at the University of California, Irvine and Senior Research Scientist for the Radar Science and Engineering Section at NASA’s Jet Propulsion Laboratory. The 6th IPCC Report and Sea Level Rise Chris Machens: Hello Eric, back in 2015 I’ve asked you about…
In this talk from October 2019, Eric Rignot suggests the possibility of 4 meters of sea level rise per century. Just extrapolating based on Antarctic marine glaciers retreating would yield the figure Notes a new model with results in the ballpark Notes the figure is in agreement with past sea level rise estimates Not mentioned…
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…
Scientists at the University of Alaska Fairbanks’ Geophysical Institute used data from NASA’s Operation IceBridge to develop a more accurate model of how the Greenland Ice Sheet might respond to climate change in the future, finding that it could generate more sea level rise than previously thought. Watch a narrated NASA model visualization In the…

In ca 2012, 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…
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. This strange story of smoke, dust and algae looks at the lesser-known half of a positive feedback loop: not only does climate change make fires bigger and badder,…
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…
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…
