Warm Bias of about 30% in the IPCC Reported Surface Temperature Trends

Update: The evidence just keeps coming.

Quoting PhD Climatologist Dr. Roger Pielke Sr.:

“Our [peer reviewed] paper… has clearly documented an estimated warm bias of about 30% in the IPCC reported surface temperature trends. This bias also brings into question the claim that 11 of the 12 years in the period 1995 to 2006 were the warmest on record. Moreover, despite the claim in the IPCC (2007) report, the tropospheric and surface temperature trends have not NOT reconciled...

The lack of news coverage on this documented bias which has appeared in the peer reviewed literature on the Klotzbach et al (2009) paper is another clear example of the failure of most of the journalism community to cover news that conflicts with the IPCC (2007) perspective.”

The cited peer reviewed science is:
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.
