The official story when attempting to rewrite the history of the 1970s global cooling scare goes something like this:
In 1945, after 30 years of rapid warming, humans suddenly started dumping huge amounts of aerosol pollution into the atmosphere. When the clean air act passed in the US, suddenly the whole world stopped polluting and temperatures started to rise quickly – due to CO2 (of course.)
But now that Hansen’s 1988 forecasts have bombed, he is trying to resurrect the evil aerosols for a second round of blame.
We conclude that most climate models mix heat too efficiently into the deep ocean and as a result underestimate the negative forcing by human-made aerosols.
All climate can be explained by human made CO2 and human made aerosols, except for climate which is due to human made CFCs.
