What I am saying is that it makes no sense at all to hand - wave at the effects of uncontrolled volcanic eruptions as «absolute proof» that geoengineering schemes «can work», while promoting a gradual 50 - year phaseout of GHG emissions (which is too slow to have any hope of preventing catastrophic outcomes) as «logical» (whatever that means) and ignoring the multiple studies that show we can easily phase out emissions in a fraction of that time with the proven technologies that are already at hand.
What he really means, of course, is that additional volcanic activity, had it taken place, would have added more aerosols, thus slowing the overall dissipation, which would in turn have enhanced the cooling effect of said aerosols.
I say usually, since there are cases such as the trees flattened by the Tunguska impact, or buried by volcanic ash, that quite obviously recorded direct effects these event.
Victor, if an absence of volcanic aerosols results from their «dissipation» and this in turn results in a «rebound» as you say it does, is not such a «rebound» a «real effect» resulting from an «absence» (or more usually a partial absence) of volcanic aerosols?

Backing that up, NASA says that 1) sea surface temperature fluctuations (El Niño - La Niña) can cause global temperature deviation of about 0.2 °C; 2) solar maximums and minimums produce variations of only 0.1 °C, warmer or cooler; 3) aerosols from natural sources such as volcanic eruptions (Mount Pinatubo for example) have caused average cooling of 0.3 °C, but recent eruptions have had not had significant effect.
I'm not interested in where you ski, but that it seems you're saying volcanic activity and hot material reaching the earth's crust have no effect on temperature or climate.
Volcanic effects have been exaggerated, as I've discussed above and you have said many times there is little evidence that volcanic effect is anything near what the models Volcanic effects have been exaggerated, as I've discussed above and you have said many times there is little evidence that volcanic effect is anything near what the models volcanic effect is anything near what the models produce.
