800,000-Year History of Atmospheric CO2
Comment from YouTube viewer:
Deniers that human activity is causing climate change are like the Black Knight in Monty Python and the Holy Grail. It makes no difference how much evidence is presented they will still deny the reality of the situation.
King Arthur: “Look, you stupid Bastard. You’ve got no arms left.”
Black Knight: “Yes I have.”
King Arthur: “Look!”
Black Knight: “It’s just a flesh wound.”

It’s very cool – “the earth is breathing” – the first (most cool) half is for 1979+, then it goes backward in time.
