Some people and organizations are starting to use their “little grey cells”!
An extract: “On a final note, the problem of large government climate change assessments being scientifically outdated even before they are released is not atypical of “group science,” which is hugely expensive, grossly inefficient, and often is designed to justify policy. We noted the same thing in our comments on the recent draft report of the U.S. effort at assessing climate change impacts, the “National Climate Assessment” (NCA), stating:
To the extent that the recent literature ultimately produces a more accurate estimate of the equilibrium climate sensitivity than does the climate model average, it means that, in general, all of the projections of future climate change given in the NCA are, by default, some 40% too large (too rapid) and the associated (and described) impacts are gross overestimates.
Our recommendation is that an alternative set of projections be developed for all topics discussed in the NCA, incorporating the latest scientific findings on the lowered value of equilibrium climate sensitivity. Without the addition of the new projections, the NCA will be obsolete on the day of its official release.
And to think, these national and international assessments are undertaken to justify policy actions.
Scary thought.“
