In its latest “Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX)”, whose “Summary for Policymakers” (1) is dated November 18, 2011, the IPCC writes (my emphasis):
(p9) “Projected changes in climate extremes under different emissions scenarios generally do not strongly diverge in the coming two to three decades, but these signals are relatively small compared to natural climate variability over this time frame. Even the sign of projected changes in some climate extremes over this time frame”
Therefore people trying right now to discern/portray climate change of the extreme variety, (“disasters [that] produce widespread damage and cause severe alterations in the normal functioning of communities or societies“, according to the IPCC – in other words the only changes of actual practical interest), are placing themselves outside mainstream science, perhaps out of naivety, perhaps due to personal gain.
In any case, not one of the usual suspects will lament such a manipulation of the best evidence we have. Who needs skeptics when believers are so determined to sustain each other through long-distance charades?
