  1. 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 most recent rise stopped in August 2023, and has been declining since (NOAA SST v5 monthly). 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 (Berner et al., 2008). 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. And Life just carried on.
