New Study: A Post-2000 Increase In Absorbed Solar Energy ‘By Far The Largest Contribution’ To Warming

Scientists have once again affirmed the 2000-2020 total greenhouse effect (longwave) forcing has been declining in recent decades just as absorbed solar radiation has been increasing due to cloud albedo modulation. The latter explains the net positive Earth Energy Imbalance (EEI) and consequent global warming during this period.
Recently we detailed the satellite-observed decline in total (“all sky”) greenhouse effect forcing since 1985 and the concomitant increase in surface solar radiation over the last 35 years.
Yet another scientific paper has been published affirming a -0.23 W/m² per decade−1 decline in total longwave forcing (the net impact due to changes in greenhouse gases and cloud cover) and a +0.66 W/m² per decade−1 (+1.3 W/m²) increase in absorbed solar radiation during the 21st century (March 2000 to March 2020).
The net absorption of solar energy that has occurred due to the reduction of solar radiation reflected to space by clouds and aerosols is “by far the largest contribution to the increasing rate of change of EEI.” In other words, the impact of CO2 and other greenhouse gas forcing together with cloud has contributed a net cooling influence that has been soundly superseded by the increasing solar radiation trend.
