There is a news release titled July 29, 2010 EPA Rejects Claims of Flawed Climate Science.
It is based on
I am going to comment here on just one of the EPA findings in the rejection. In EPA Rejects Claims of Flawed Climate Science they write
“…the IPCC report… provided a comprehensive and balanced discussion of climate science.”
The EPA, however, in contrast to what they write, chose to ignore the conclusion of such reports, peer reviewed papers, and testimony as

as well as documentation of the deliberate successful attempt to exclude viewpoints in the CCSP and IPCC reports which differ from the EPA findings; e.g.
Pielke, R.A. Sr., 2005: Public Comment on CCSP Report “Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences”. 88 pp including appendices.
The EPA claim that
“After months of serious consideration of the petitions and of the state of climate change science EPA finds no evidence to support these claims”
It is almost trivial to show that the EPA is not properly considering peer reviewed research that differs from their findings.
As just one example, they write
“The global warming trend over the past 100 years is confirmed by three separate records of surface temperature, all of which are confirmed by satellite data.”
There are not three independent records of surface temperatures trends as we reported in our Pielke et al 2007, i.e.
“The raw surface temperature data from which all of the different global surface temperature trend analyses are derived are essentially the same. The best estimate that has been reported is that 90–95% of the raw data in each of the analyses is the same (P. Jones, personal communication, 2003).
They also ignored peer reviewed research that shows a discrepancy between the surface and lower tropospheric temperature trends; i.e.
Klotzbach, P.J., R.A. Pielke Sr., R.A. Pielke Jr., J.R. Christy, and R.T. McNider, 2009: An alternative explanation for differential temperature trends at the surface and in the lower troposphere. J. Geophys. Res., 114, D21102, doi:10.1029/2009JD011841.
This EPA Denial is yet another perpetuation of the group think that was so evident in the released CRU e-mails.
