Insightful video. CO2 coalition (funded by Exxon) says 140-million year trend of dangerously decreasing CO2, with the implication that more CO2 is good. Potholer54 talks about this paper. Two insights:
a) CO2 levels have been below 200PPM for millions of years, and life on the planet was fine.
b) Over 140 million years, CO2 has been dropping 0.00001 ppm/year. We are adding 2 PPM/year now, 200,000x faster. This rate of change is unprecedented.
