In 1981, Hansen predicted this CO2 warming. This is from his conservative days, which Gavin’s FakeClimate likes to brag about.
I overlaid GISS 1997 global temperatures on top of Hansen’s 1981 forecasts for CO2 warming. It shows that most warming occurred before CO2 warming “kicked in.”
Warming by 1940 was 5X CO2 warming.. A special thanks James Hansen for proving that natural variability overwhelms CO2.
