CO2 is the source of life. I guess abortions aren't killing life fast enough.
There are hints from history that CO2 could afford to go quite a lot higher.
Nature adjusts in the long run. It always has. If getting clobbered by a meteor didn’t put the earth out of the picture, how can man’s feeble fires? We don’t even know close to all the species out there, sitting in little groups against the day that the Lord knows they will be needed to go widespread.
