This article lists all of the failed predictions. This is just a partial list if you include all of the politicians who have prognosticated our future.
In 2009 when Al Gore said in the next 5 to 7 years there will be no ice in the Arctic. I remember back in 2014 to 2016 when the polar ice cap just magically disappeared.
In 1969 when a Standford professor said "We must realize that unless we are extremely lucky, everybody will disappear in a cloud of blue steam in 20 years" (https://www.nytimes.com/1969/08/10/archives/foe-of-pollution-sees-lack-of-time-asserts-environmental-ills.html).
Why this is important? Because now the idiots are seriously looking for ways of reducing the amount of solar radiation that will hit the earth in an effort to end climate change.
I don't know about you but if all of the prognosticators and clairvoyants can't seem accurately predict anything the LAST thing I want those people doing is messing with the planet. They're insane.
Even worse, the global fascists (who invented global climate fear) are using this "science" to achieve their goals. The impending climate disaster is causing them to promote "15-Minute Cities", meaning everything they decide you need will be within a 15 minute walk or bicycle ride.
