Early Homo species were surviving quite nicely with CO2 levels above 2500 ppm. Early mammals and dinosaurs at 8000 ppm.
If the planet ever warms to its optimal 69F temperature (It is at 60F today), then atmospheric CO2 will be about 1200 ppm. It is really too bad man can't cause global warming...It would be ideal. |
Now you're mixing the heating problem with the gas problem I'm highlighting.
Early homo sapiens have NEVER existed with CO2 levels at the 2500 PPM level, and the end of this century is nowhere long enough for us to evolve to be able to. You have to go further back than about 16 million years ago to see where it was higher than 1,000, but then it was dinosaurs that had to deal with it and not humans. In the 30,000 years we've been around, the levels were much lower than today.
You can do your own research to find out what effect CO2 levels has on us. But Elon got it right - it is dangerous to our health and we're not even talking about it. The higher the level, the less our lungs are able to remove it from our blood and you end up with the effects Elon highlighted.
