I knew global warming was a reality in high school in the 1980s. Had a different name then. Something about the ozone and greenhouse. But I already knew from Carl Sagan that politicians don’t do science well, from my own observations that most dire predictions are from 10-50 years and almost none come true and are usually to give an excuse for government funding.
