Everyone should watch Sagan teaching climate change to Congress back in 1985: https://youtu.be/Wp-WiNXH6hI
40 years ago.
It’s so easy to lose sight among all the gish-galloping nonsense around these topics just how long the problem has been almost fully understood and very clearly articulated. It’s absolutely devastating to think about how catastrophically the world has failed to meet the challenge he describes here in the intervening decades.
While I adore Sagan, the greenhouse effect was was proposed as early as 1824 by Joseph Fourier (yes Fourier transform dude). Literally two centuries old science.
I didn’t intend to suggest that Carl Sagan invented climate science in 1985, just that the political conversation has been clear and ongoing for decades (indeed, longer than 40 years), yet the opposing narratives continue to claim it’s unproven, and the progress remains insufficient.
