Some key points to understand:
- the 1.5C target has already been surpassed
- with temperature increasing at an accelerated pace since 2010 of 0.36 C per decade (double the rate of rise from 1970 to 2010) we will gain an additional 0.5 in less than 15 years (15 year rise will be 0.36 x 1.5 equals 0.54 C) which will bring us above 2 C by 2040 at the latest
- climate sensitivity is 4.5 C for a doubling of CO2, much higher than the IPCC value of 3 C
- AMOC will likely collapse before 2050 due to fresh water hosing in the North Atlantic at much higher rates (double) than the value used in Hansen's previous paper
- last time AMOC shut down, global sea level rise went up several meters. Clearly, with an AMOC shutdown cooling the Arctic more heat builds up in the Southern Hemisphere and equatorial regions, so Antarctica melt rate increases rapidly and dominates the reduced melt rate from Greenland glaciers
