Incredible in light of the most recent National Climate Assessment.
I wonder if Dr. Sagan would have believed that human’s would have let things get to this dire place.
Certainly I would not have.
Below, Sagan mentions climate change on Johnny Carson’s Tonight Show in 1978. (go to 13:10)
Sagan’s 1990 framing of of climate change denial was brilliant. 28 years later I hope we are finally catching on and catching up to his insight.
He also talked about the effects of a nuclear winter cooling the planet. I believe they will reach for the nuclear winter option, any day now.
