Reading back further thru the file, one sees that the drift in NOAA 15 was apparent as far back as 6 Apr 2006. Now, UAH (John Christy, et al.) seems to be claiming that they can't really say what is happening with the Temps for the past few years. I suppose Jonh Christy has been too busy with other activities, such as writing for the media. Here's one example: http://news.bbc.co.uk/2/hi/science/nature/7081331.stm For anyone still wondering about the science, there was a recent GRL report in which the MSU data was analyzed over the Antarctic in a bit different way to show a warming trend in some of the seasonal data for the troposphere. I think it's also interesting that they find what appears to be anti- correlation between their tropospheric and stratospheric data (See Figure 2). Here's the reference: Celeste M. Johanson and Qiang Fu, "Antarctic atmospheric temperature trend patterns from satellite observations", Geophys. Res. Lett., 34, L12703, 19 June 2007, doi:10.1029/2006GL029108. I most humbly thank the authors for referencing my 2003 GRL paper . E.
