These people are utterly insane, just completely delusional low IQ psychopaths.
Anyone ever read the book “The Road” by Cormac McCarthy or see the movie? That is exactly what the earth would be like should the CO2 level ever descend below 0.02% or if the sun was ever blotted out, plants would die and after the animals die or are killed off people would resort to cannibalism.
Maybe these asshats should ask themselves why the record high temperatures for almost every state in the USA was set decades ago. Pretty strange if the temperature is getting hotter every year isnt it.

I have seen the movie. Very unsettling.
