Eric Rignot: Sea level rise there is a distinct possibility it could go faster

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…

Discovery: Process of ice mélange thinning suggests Antarctica’s ice-shelves could retreat Decades Earlier

Ice shelves buttress glaciers – a new mechanism involving rift dynamics suggests ice shelfs could retreat faster than previously modeled. SciTechDaily: “The thinning of the ice melange that glues together large segments of floating ice shelves is another way climate change can cause rapid retreat of Antarctica’s ice shelves,” said co-author Eric Rignot, UCI professor…

Study: Interacting tipping elements increase risk of climate domino effects under global warming

The study, “Interacting tipping elements increase risk of climate domino effects under global warming” by Nico Wunderling, Jonathan F. Donges, Jürgen Kurths, and Ricarda Winkelmann from the Potsdam Institute finds potential severe consequences from continued climate change. The Guardian has a study breakdown, which can be accessed here. Analysis shows significant risk of cascading events even at 2C…

Humans have locked in at least 20 feet / 6 meters of sea level rise—can we still fix it?

By Harold R. Wanless, professor of Geography and Regional Studies, University of Miami, published by EOS. The climate emergency is bigger than many experts, elected officials, and activists realize. Humanity’s greenhouse gas emissions have overheated the Earth’s atmosphere, unleashing punishing heat waves, hurricanes, and other extreme weather—that much is widely understood. The larger problem is…

Audio: Overshooting 2C risks rapid and unstoppable sea level rise from Antarctica

CarbonBrief recently published a guest article by Robert M. DeConto, Pamela Pearson, and David Pollard, called Overshooting 2C risks rapid and unstoppable sea level rise from Antarctica. Here is now a text-to-speech conversation for people who like to listen to it. Visit Overshooting 2C risks rapid and unstoppable sea level rise from Antarctica to follow…

The Doomsday Glaciers in East Antarctica | Earth Under Water

A new study suggests that the East Antarctica Ice Sheet in the Wilkes Basin may have completely disappeared around 400,000 years ago. Currently the Wilkes Basin is only hold back by the Cook, Mertz, and the Ninnis glacier – the Cook Glacier shelf has already collapsed. There is also the Totten Glacier farther to the…

Antarctic & Greenland Melt Accelerates Sea Level Rise (Eric Rignot October 2019)

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…

When will the Netherlands disappear below sea level?

It’s difficult to imagine, but currently the Netherlands is on a trajectory to be swept away by sea level rise. Previous measures are no longer sufficient enough in light of more recent knowledge. The question is not if the Netherlands will disappear below sea level, but when https://www.uu.nl/en/news/the-question-is-not-if-the-netherlands-will-disappear-below-sea-level-but-when As sea levels rise, how long until…

Ice Tsunamis: Can Ice Stream Collapse accelerate Sea Level Rise?

A Never-Before-Seen Event Is Collapsing an Ice Sheet in the Russian Arctic – Will ice stream collapse accelerate Sea Level Rise super extreme? Scientists have discovered a rare event, a collapsing ice sheet. With already multi meter sea level rise estimates from global warming, this highlighted event may accelerate trends further, with serious implications for…
