Today I read an article that in October Iceland officially classified the failure of the Atlantic meridional overturning circulation (AMOC) as a national security risk. If the AMOC were to fail, temperatures in Iceland could plunge to -50º Farenheit and would glacier over.
I first heard about the AMOC in the highly recommendable book “A Short History of Nearly Everything” by Bill Bryson. From what I remember is that he said: look at where England is and then trace on a globe to see where that lines up at on North America. Why is one a tundra and the other highly populated? AMOC.
Read on to see my notes on AMOC.
