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.”
Hansen will never admit that his earlier forecasts have been terribly wrong. He just says the warming process, for whatever BS reason, has been delayed a few years. He is still just as anxious to get into our wallets for the purpose of “mitigating” a non existent problem.
He’s grasping at straws that are not even there in the hope the next five years will bring climbing temperatures.
Gavin Schmidt disagrees with Hansen. The Gavin wrote a short article for Physics Today several years ago, in which he provided ‘compelling evidence’ that climate models accurately replicated the global temperature response to Pinatubo’s eruption. This included a graph showing that the eruption’s impact on global T vanished by 1995.
Perhaps the cooling volcanic aerosols were not permanently sequestered, but temporarily stored with the missing heat in the deep oceans, only to reappear several decades later.
Or its all just another manifestation of Langmuir’s fifth law, enumerated at numberwatch.co.uk-
Langmuir’s Laws of bad science
1 .The maximum effect that is observed is produced by a causative agent of barely detectable intensity, and the magnitude of the effect is substantially independent of the intensity of the cause.
2. The effect is of a magnitude that remains close to the limit of detectability, or many measurements are necessary because of the low level of significance of the results.
3. There are claims of great accuracy.
4. Fantastic theories contrary to experience are suggested.
5. Criticisms are met by ad hoc excuses thought up on the spur of the moment.
6. The ratio of supporters to critics rises to somewhere near 50% and then falls gradually to zero.
I’m not a scientist but a computer guy, yet when I read any claim made by Hansen it sounds like preposterous bullshit. How can anyone seriously believe his shameless nonsense?
He and Trenberth are of the “dog ate my homework” school of climatology, making up new excuses whenever their predictions are countered by reality.
Bunch of… ah, never mind.
So the warming we had up til about 1998 would have been much worse if it weren’t for Mt Pinatubo? Or did the aerosols from that event just take a holiday until then?
At least Hansen thinks that the sun has something to do with climate; that must be some kind of breakthrough.
Is “missing heat” the same thing as cooling? If so, then it sounds like political talk to me.
Had not heard of Langmuir’s Laws until now. What a perfect description of AGW science.
