The fix was in on our climate by the 90’s, the Co2 levels are above 450 ppm. This doesn’t have an equivalent in many millions of years. The effects of heat building is cumulative, the earth still has plenty more room to store heat energy, and we’ve already put more than enough Co2 in the atmosphere to warm well past 2C. We’ve got years left, not decades. Wait till food distribution systems break down, that’s when it’ll hit everyone that this is already a done deal. Things will begin to break down rapidly in the next few years.
