'Serious risk' of vital ocean current collapse by 2100, warn scientists

Raw Story  

A group of 44 climate scientists from 15 different countries warn there is a "serious risk" that soaring global temperatures will trigger the "catastrophic" collapse of a crucial system of ocean currents—and possibly sooner than established estimates considered likely. "Given that the outcome would be catastrophic and impacting the entire world for centuries to come, we believe more needs to be done to minimize this risk." "It is an amplifying feedback: As AMOC gets weaker, the subpolar oceans gets less salty, and as the oceans gets less salty then AMOC gets weaker," Rahmstorf explained. Johan Rockström, a letter signatory who leads the Potsdam Institute for Climate Impact Research, wrote on social media that global politics, "particularly in Nordic region, can no longer exclude risk of AMOC collapse."

Scientists warn that a crucial ocean current could collapse, altering global weather

LA Times  

Scientists are sounding the alarm that a crucial component of the planet’s climate system is in gradual decline and could one day reach a tipping point that would radically alter global weather patterns. Considering the AMOC is the workhorse of the Atlantic, the consequences of such a collapse would result in “hugely chaotic changes in global weather patterns” that extend …
