Another week, another excuse
(The Hockey Schtick ) New excuse #56 for the “pause” in global warming: Satellites underestimate cooling from volcanic aerosols
A paper published today in Geophysical Research Letters states,Â
“Understanding the cooling effect of recent volcanoes is of particular interest in the context of the post-2000 slowing of the rate of global warming”
and finds
“recent volcanic events are responsible for more post-2000 cooling than is implied by satellite databases” which “translates into an estimated global cooling of 0.05 to 0.12 °C.”
By way of comparison, the IPCC formula claims post-2000 warming from CO2 was 5.35*ln(400/369) = 0.43W/m2 *(3C/3.7Wm-2) = 0.35C warming, which is at least three times larger than the estimated volcanic cooling found from this paper. Therefore, volcanic cooling would not be sufficient to account for the zero degrees global warming post-2000 (actually post-1996). This implies that either this new paper is incorrect regarding volcanic cooling account for the “pause,” or that the IPCC exaggerates climate sensitivity to CO2.Â
It’s always interesting how Warmists so often blame nature for the Pause, but hyper-ventilatingly blame Humanity for the warming. It’s almost like they aren’t actually interested in science.
