CO2 level is now 392 and growing
This is a good site to look at from time to time to remind us where we are and where we are headed steadily. Our CO2 now is 392. The historical level in the last 400,000 years was 280. The maximum scientists believe the Earth can tolerate without severe degradation is 350. The "best" estimate is 550 by 2050. Yet, we are doing nothing to slow this rapid rise.
"We know that before 2050, atmospheric CO2 will cross the 500 ppm threshold, a level last seen during the Eocene, 55 million to 36 million yeas ago. There were palm trees in Wyoming and crocodiles in the Arctic then. Antarctica was a coniferous forest, Because there was no continental ice sheets, sea level was 100 meter [328 feet] higher than today."
