I've mentioned before the web-based efforts of Surface Stations to have volunteers audit and photograph all 1,221 official NOAA surface temperature measurement sites. They're not done yet, but they just passed a milestone: over 70% of those sites have now been audited. The graph at right shows the results.
These are the same sites that the NOAA and Jim Hansen of NASA specifically call out as being more accurate and more reliable that satellite-based temperature measurements. The cumulative errors that Surface Stations has now documented in these stations is approximately the same as the difference between the satellite measurements and the surface measurements.
In other words, the satellites are right.
And global warming isn't nearly as severe as its adherents would have us believe.
If I believed in an afterlife, I'd hope there was a special sort of hell reserved for corrupt scientists...
