Re, All I am saying world populations climbing co2 increasing ,forests disappearing ,NASA: HIGHER CO2 LEVELS RESPONSIBLE FOR ‘GREENING’ EARTH
New research confirms rising CO2 levels are driving the “greening” Earth effect observed by satellites.
A CO₂-richer world
Plants need CO₂ to grow through photosynthesis. We found that the biggest factor in driving the global greening trend is the fertilisation effect of rising atmospheric CO₂ due to human activity (atmospheric concentration grew by 46 parts per million during the period studied).
This effect is well known and has been used in agricultural production for decades to achieve larger and faster yields in greenhouses.
In the tropics, the CO₂ fertilisation effect led to faster growth in leaf area than in most other vegetation types, and made this effect the overwhelming driver of greening there.
