Go to wikipedia, look up the last major geological time scales 350 million years ago till now. And note thr co2 levels....
If co2 is so horrible, how did massive dinos survive for hundreds of millions of years with levels of co2 several times HIGHER than what libs consider apocalyptic? ??????
The dinos supposedly would have suffocated/drowned/burned to death before they ever had a chance to live for nearly 150 million years......
” We try to keep CO2 levels in our U.S. Navy submarines no higher than 8,000 parts per million, about 20 time current atmospheric levels. Few adverse effects are observed at even higher levels. – Senate testimony of Dr. William Happer”
