- 'Particulate aerosol pollution reductions...led to an increase in surface radiative forcing'
It has been assumed COVID lockdowns and their associated reductions in human CO2 emissions would be a “step in the right direction” with regard to climate change mitigation. But a new study finds the particulate (aerosol) pollution reductions from less industrial and transportation activity in Europe during the months of March to May (2020) actually led to an increase in surface radiative forcing ~65 times greater than from business-as-usual CO2 emissions.
The researchers find that the current levels of atmospheric CO2 and water vapor are close to saturation. Saturation is a technical term meaning that the greenhouse effect has already had its maximum impact and further increases in concentration will cause little additional warming.
