The method used to calculate such low
values of climate sensitivity fails to include important regional dynamics in the climate response, and this has been shown to bias it toward low values.
The TSD purports to rely on IPCC work as a basis for a supposed «
sensitivity»
of climate to increasing atmospheric C02, but
fails to mention that the most recent IPCC report completely undermines any basis for determining
climate sensitivity with the following statement: «No best estimate for equilibrium
climate sensitivity can now be given because
of a lack
of agreement on
values across assessed lines
of evidence and studies.»
