The Carbon Conundrum: Did Earth’s Greenest Periods Demand High CO2?
By P Gosselin on 15. October 2025
A “green Earth” is inextricably linked to high atmospheric CO₂ concentrations
A new paper by Dutch independent scientist Frans J. Schrijver, Historical CO₂ levels in periods of global greening, looks at CO2 and increased global greening.

The Earth is getting greener. Satellite data confirms a significant increase in vegetation—or global greening—over the past century, with Gross Primary Production (GPP) –the rate of carbon fixation by plants– rising by over 30% since 1900.
The prevailing scientific consensus attributes this surge primarily to the CO₂ fertilization effect, meaning higher atmospheric carbon dioxide allows plants to photosynthesize more effectively.
