I'm scheduling this post late at night which means I'm too tired/lazy to do any research. I have memory! I might be wrong. I'll do the research and update tomorrow. But my memory is back in in the dark ages of 2000, there was a clique of prominent people who agreed climate change was real and suggested that spending ONE HUNDRED BILLION DOLLARS to fix it was unaffordable.
ONE HUNDRED BILLION DOLLARS was probably an absurdly low estimate, but what's obviously more absurd is that it wouldn't have been worth that much to solve the problem.
