From: Indian Ocean corals reveal crucial role of World War II bias for twentieth century warming estimates
WW II bias correction and coral-temperature correlation. Scatterplots of annual mean WIO coral temperature vs. (a) WIO HadSST37,8 and (b) WIO HadSST222. Green dots: 1961–1990, magenta dots: 1941–1960 (WW II bias), blue dots: 1921–1940. Note the improved correlation between WIO HadSST3 and WIO coral temperature during the time period affected by the WW II bias. Correlation coefficients are calculated over the 1921–1990 period and omitting the WW II bias period from 1941–1960 (in brackets).
