> if the global warming trend is not reversed by the year 2000
The trend was not reversed, so now we wait to see if the prediction comes true. Given the low lying geography of some nations (esp pacific islands) I would bet money that this does indeed come true in the future.
Nowhere in the quote does it say, as you claim, that civilization would collapse in 2000.
Furthermore, those unspecific weasel words they were using back then to try and wriggle out of any predicitons they made back then, they are still using today when they say we will be past the point of no return in 10 years from now. Their wording was clearly meant to trick people into believing there would be mass destruction and climate refugees in 10 years, and people believed it back then, just like people today believe we will be seeing the same in 10 years from now.
