The memes of the climate

By "the 50s," do you mean the 1850s, when Eunice Newton Foote discovered the greenhouse effect, and calculated that CO~2~ emissions would change the climate? And when John Tyndall published the same thing, because the scientific community ignored her because she was a woman? Yeah, we could have started 170 years ago, but people just aren't wise enough to do anything about climate change until it's too late.
