From No Tricks Zone:
The last 40 years of global temperature changes can be radiatively explained by a natural reduction in cloud cover.
From 1979 to 2011, satellite data provide documentation of a reduction in cloud cover and aerosol depth that allowed an additional 2.3 W/m² of positive shortwave energy to be absorbed by the Earth’s surface rather than reflected to space.
This change in absorbed solar radiation can account for the energy imbalance and warming during this period far better than the much smaller 0.2 W/m² forcing associated with a +22 ppm CO2 change over 10 years (representing just 10% of the overall trend in downwelling longwave).
