Climatologist Dr. Roger Pielke Sr. rips ‘failure’ of new Fed Report: ‘That much of the media accepted the NCA without questioning its findings and conclusions either indicates they are naive or they have chosen to promote a particular agenda and this report fits their goal’

Hi Judy Excellent analysis of the NCA. Your text

“The report effectively implies that there is no climate change other than what is caused by humans, and that extreme weather events are equivalent to climate change”

“The failure to imagine future extreme events and climate scenarios, other than those that are driven by CO2 emissions and simulated by deficient climate models, has the potential to increase our vulnerability to future climate surprises”

succinctly shows the major failure of their report.

With respect to their equivalence of climate change to just that driven by CO2 emissions, this issue was clearly refuted in

National Research Council, 2005: Radiative forcing of climate change: Expanding the concept and addressing uncertainties.

The failings of the models with respect to multi-decadal climate predictions (projections) is documented, for example, in

Pielke Sr., R.A., and R.L. Wilby, 2012: Regional climate downscaling – what’s the point? Eos Forum, 93, No. 5, 52-53, doi:10.1029/2012EO050008.http://pielkeclimatesci.files.wordpress.com/2012/02/r-361.pdf

Suding, C. Wright, Eds., Academic Press, 1570 pp.http://pielkeclimatesci.files.wordpress.com/2013/05/b-18preface.pdf

That much of the media accepted the NCA without questioning its findings and conclusions either indicates they are naive or they have chosen to promote a particular agenda and this report fits their goal.
