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…

The Climate State may Tip at 1.5 or 2 C of Global Temperature Rise

These results indicate that climate tipping is an imminent risk in the Earth System. Even the safe operating space of 1.5 or 2.0 degrees above present generally assumed by the IPCC might not be all that safe. According to the precautionary principle, we must consider abrupt and irreversible changes to the climate system as a real risk – at least until we understand these phenomena better.
