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…

Floods Devastate German Towns

Heavy rains caused flooding in regions of West Germany, affecting the region of Ahrweiler (Rheinland-Pfalz).

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.
