Doug Bostrom#ClimateDenier "it's ok" argument shrivels.
"We show that the initial positive effect of eCO2-induced climate change on vegetation carbon uptake has declined recently, shifting to negative in the early 21st century. Such emerging pattern appears prominent in high latitudes and occurs in combination with a decrease of direct CO2 physiological effect, resulting in a sharp reduction of the current growth benefits induced by climate warming and CO2 fertilization."
Transition from positive to negative indirect CO2 effects on the vegetation carbon uptake - Nature Communications
It is unclear how indirect CO2 effect – via associated climate change – on vegetation carbon uptake changes globally. Here, the authors show that such initial positive effect has declined recently, shifting to negative in the early 21st century.
