We conclude that recent slowdown of ocean heat uptake was caused by a delayed rebound effect from Mount Pinatubo aerosols and a deep prolonged solar minimum. Observed sea level rise during the Argo float era is readily accounted for by ice melt and ocean thermal expansion, but the ascendency of ice melt leads us to anticipate acceleration of the rate of sea level rise this decade.
A couple of months ago the missing heat was due to Chinese aerosols. Now it is due to Pinatubo aerosols from 20 years ago.
Earth to Jim – Pinatubo aerosols were gone by 1995. There has been essentially no warming since then.
The sun didn’t affect the temperature when it had record high activity last century, but now it affects the temperature since temperatures stopped rising.
Hansen said this in October:
“the solar forcing is too small to make the net imbalance negative, i.e., solar variations are not going to cause global cooling.”
