Marko, Soon et al: To Put America First Is to Put Our Planet’s Climate First | Tallbloke’s Talkshop

The average residence time of a CO2 molecule in the Earth’s atmosphere is about four to seven years. Taking into account multiple exchanges leads to an estimate of a mean lifespan of 40 years (Harde 2017). Rather than a problem, carbon dioxide in the atmosphere is the prime nutrient for plants. Indeed, plants grow more strongly when CO2 concentrations are much higher than they currently are, which is why commercial greenhouses add CO2 to the air. The current CO2 concentration is higher than for 800,000 years, but it is far lower than at almost any time in the previous history of our planet.
