I might mention that plants need CO2 for it is their way of surviving, and they produce O2 which we need. But we can not breathe CO2. But the real reason for the global warming scare is the newspapers can not be sold unless they are predicting some dire catastrophe.
The amount of CO2 in the atmosphere during the Jurassic era was 1800 parts per million; and at the start was 2100. The amount of CO2 in the atmosphere now 419.39 ppm. That is the amount now is about a fourth of what it was when the dinosaurs were around.
Ii would like to add here that papers about the subject tend to rely on computer modeling. But there are plenty of equations that go to infinity, but a computer will miss completely unless you enter the exact amount. See the lectures of Dr Strang at MIT where he mentions this. Besides the computer depends on input data. so it all depends on what you put in.
