Correct. The public are lead to believe that 440ppm co2 is too great and if the planet heats up by 3c, it's the end of civilization.
Before the political science, science concluded that in the Cretaceous period, it was 2,400pm co2 and so 4c warmer than today, on average. But why didn't life evaporate? In fact, it flourished, so much so, this was the period in the earth's history the dinosaurs apparently flourished. It took a meteorite to wipe them out.
So where does manmade climate change come into this? Did science for donkey years get it wrong, or is the science of today motivated by something else!!
