Climate activists have been making absurd claims about the effect of climate change on the Earth and predicting humanity’s demise for decades. The world was supposed to have ended several times over by now!

With politicians like Rep. Alexandria Ocasio-Cortez claiming without scientific evidence that we have just twelve years left to live — or ten, or even five — it’s easy to see why the American people are resistant to big-government climate-change takeovers.

Here are just a few of the outrageous and unscientific doomsday prophecies that haven’t come true:

“Entire nations could be wiped off the face of the earth by rising sea levels if global warming is not reversed by the year 2000.”

Noel Brown, Senior UN Environmental Official, 1989

“World leaders have 50 days to save the Earth from irreversible global warming.”

Gordon Brown, Former UK Prime Minister, 2009

“If there’s no action before 2012, that’s too late. What we do in the next two to three years will determine our future. This is the defining moment.”

Rajendra Pachauri, Head of the U.N. Intergovernmental panel on climate change, 2007

“I think we have a very brief window of opportunity to deal with climate change … no longer than a decade, at the most.”

James Hansen, NASA Scientist, 2006

“Civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind.”

George Wald, American Scientist, 1979

“Politicians and corporations have been ignoring the issue for decades, to the point that unless drastic measures to reduce greenhouse gases are taken within the next 10 years, the world will reach a point of no return.”

Al Gore, former Vice President, 2007

“As University of California physicist John Holdren has said, it is possible that carbon-dioxide climate-induced famines could kill as many as a billion people before the year 2020.”

Paul Ehrlich, biologist, 1986

Contrary to this alarmist hyperbole, climate change hasn’t destroyed the planet. In fact, life has gotten dramatically better — thanks in large part to increasing access to affordable, reliable energy.
