“If there was a significant reduction in CO2 , forests, crops, sea plants, etc., would be adversely affected.”
At 150ppm, all plant life on Earth dies.
We’re currently at 400ppm, bouncing off an all-time planet Earth low of 220ppm during the last glaciation.
The last time both temperatures and Co2 levels were this low was 300 million years ago, Carboniferous period. (Berner2001)
Wouldn’t you think those Global Warming “scientists” would know this?
