Eureka!!! I’ve found the mechanism which explains the soon to boil deep oceans!!!!
It’s all becoming quite clear to me now. You see there that sea surface temp was, just hanging out and would have probably got a lot warmer, but suddenly there was some great suction from the depths and sucked all of the heat down from the surface!!!! In 2011 we see how the heat tried to climb out of the depths only to be sucked back down again in 2012.
The reason why this was so confusing is because of the special properties of Global Warming Heat vs just average everyday Heat.
