NASA/NOAA surface temperature data is massively diverging from more accurate satellite data.

Gavin complains about how bad the surface data is:

 We do not have direct measurements of the global mean anomaly, rather we have a large database of raw measurements at individual locations over a long period of time, but with an uneven spatial distribution, many missing data points, and a large number of non-climatic biases varying in time and space.

So instead of correcting the surface data to match the more accurate satellite temperatures, government climate scientists are doing the exact opposite and altering the data to make it even worse.

NASA has known for 25 years that satellite data is more accurate than surface data, but it gives the wrong political answer so they continue to ignore it. Why would the US space agency trust satellites?
