Klotzbach et al. 2009 Published

This post is for discussion of the issues raised in and possible implications of Klotzbach et al. 2009, published today. Here is the citation, link and abstract:
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. Link

This paper investigates surface and satellite temperature trends over the period from 1979 to 2008. Surface temperature data sets from the National Climate Data Center and the Hadley Center show larger trends over the 30-year period than the lower-tropospheric data from the University of Alabama in Huntsville and Remote Sensing Systems data sets. The differences between trends observed in the surface and lower-tropospheric satellite data sets are statistically significant in most comparisons, with much greater differences over land areas than over ocean areas. These findings strongly suggest that there remain important inconsistencies between surface and satellite records.


  1. This has been republished with Phil's name spelled right in the title. Thanks to the commenter who pointed that out ;-) I plead pre-coffee.

  2. This is a big deal, correct? Weren't Christy's data used to counter early global warming warnings? I was only able to read the abstract ...

    Thanks .. do note that version is pre-pub, and a few changes were made since. Thanks!

  4. How is this affected by the RSS/UAH divergence in land & sea in recent years - see recent posts by Jeff Id, Chad and others.
