Remember - 40 years ago it was Global Cooling. This is a red herring, used to hand-wave away the serious, broad, deep, and highly credible body of evidence that points to significant human-caused global warming. So-called "global cooling" was a fairly marginal conjecture that was floated in the 1970s but never taken very seriously by most climate scientists. Already by 1970, most climate research focused on warming, not cooling.
