Here's what the intro to the landmark 1979 National Research Council report had to say:
"A wait-and-see policy may mean waiting until it is too late."
(See this thread on that report from earlier this year: )
They did, in fact, offer some fairly dire warnings as far back as the 70s, if not earlier.
There is no debate about why we didn't act! It wasn't because we thought it might not be that bad! It was because of evil people who wanted more money! I am done yelling now!
"Great. I have absolutely no follow-up questions whatsoever. Give me 2500 words."
I mean, this was from just last year!!!
