Sen. Bernie Sanders (I-VT) warned that “we may lose the planet for our grandchildren” in a speech 28 years ago, calling the validity of his ever-evolving climate change deadlines into question.

A 1991 speech featuring Sanders’ remarks on the climate “crisis” has resurfaced on social media, showing the socialist senator warning that “we may lose the planet for our grandchildren” and adding that the environmental crisis cannot be addressed “unless you deal with the economic crisis at the same time.”

Sanders said:

The truth of the matter is, I think, that unless we move radically and boldly as you indicate, we may lose the planet for our grandchildren. Interestingly enough, I think – and I say this not because I want it to be that way but I think it is that way – you’re not going to deal effectively with the environmental crisis unless you deal with the economic crisis at the same time. What we have to do is to understand the challenge, the real challenge is how do you have a social system and an economy which does at least two things. Number one it provides decently for its people. At the same time as it does not destroy the environment.

Sanders added that national health care is an “environmental issue” because it “takes an enormous burden off the backs of working people.”

Sanders said it is crucial to bring the environmental movement and workers’ movement together, because “if the choice is either jobs or the environment, that is no choice at all”:

Sanders, who unveiled a $16 trillion climate change proposal, adjusted the doomsday clock during the last Democrat debate, proclaiming that we only have “eight or nine years” left to address the “crisis” – a change from his previous claim of 12 years:

“We don’t have decades. What the scientists are telling us – if we don’t get our act together within the next eight or nine years, we’re talking about cities all over the world – major cities – going under water,” Sanders said, ignoring the mountain of failed doomsday predictions that have yet to come to pass.

Sanders added that leaders in the fossil fuel industry are “probably criminally liable” because they “lied and lied and lied when they had the evidence that their carbon products were destroying the planet.”
