Higher than expected CO2 fertilization inferred from leaf to global observations

More evidence that Global Warming (aka climate change) is a hoax!

This is not the first scientific research confirming that the higher CO2 concentration in the air leads to more greening and more photosynthesis absorbing CO2. I bet you this is poorly reflected in climate models!

"Several lines of evidence point to an increase in the activity of the terrestrial biosphere over recent decades, impacting the global net land carbon sink (NLS) and its control on the growth of atmospheric carbon dioxide (ca ). Global terrestrial gross primary production (GPP)—the rate of carbon fixation by photosynthesis—is estimated to have risen by (31 ± 5)% since 1900, but the relative contributions of different putative drivers to this increase are not well known. Here we identify the rising atmospheric CO2 concentration as the dominant driver. ... These findings suggest a larger beneficial role of the land carbon sink in modulating future excess anthropogenic CO2 ... Four independent lines of evidence indicate intensifying terrestrial biosphere activity ...
