NATURE and NASA published two studies that the global CO2 absorbtion has more than doubled in the last 50 years due to the massive green growth, which was caused by CO2 emissions - an interesting feedback effect.
Recent pause in the growth rate of atmospheric CO2 due to enhanced terrestrial carbon uptake
Over the past 50 years, the amount of CO2 absorbed by the oceans and terrestrial biosphere annually has more than doubled..
Carbon Dioxide Fertilization Greening Earth, Study Finds
From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide... The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.
