  1. If you took away El Niño and Tonga (both natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP. There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.
