The late 1970’s were very cold in the US, while warm and dry on the leftist coast. Jerry Brown was governor of California and they suffered a terrible drought, which he blamed on global cooling.
Jerry Brown is still governor, and blames the current drought on global warming.
The winters of 1977-1979 were among the coldest in US history, and were due to global cooling.
It appears that we are headed into a sequence of similarly cold winters, which are being blamed on global warming.
There was also a large expansion of Arctic sea ice in the late 1970’s, which Mark Serreze cleverly hides by pretending there wasn’t any satellite data before 1979.
We appear to be doing a repeat of 1977-1979 – only this time experts call it “global warming” and in the 1970’s they called it “global cooling.”
In other words, most climatologists have absolutely no clue what they are talking about, and just make up sciency-sounding words to keep the funding coming in.
