One key finding is evidence that IPCC climate models used to
estimate warming fail to include several important environmental variables and therefore routinely over-estimate results.

Quoting the IPCC 1.4 to 5.8 Â °C
estimate (for doubling CO2) outside current agreements among models that the uncertainty is most likely in the 2.5 to 4Â °C range or
failing to point out that discrepancies (used by skeptics) between surface and troposphere
warming have been resolved, is misleading in my view.
The attribution studies
fail to account for the large multi-decadal (and longer) oscillations in the ocean, which have been
estimated to account for 20 % to 40 % to 50 % to 100 % of the recent
warming.
In the non-stationary environment caused by ocean

It is a pretty incompetent group of scientist who can not even use their closest to observation models to
estimate the predicted harms of CAGW, but instead use the modeled mean of the way to
warm models to inflate the predicted but
failing to manifest harms.
