If Ian doesn't don't like some data -- which would be nearly all the data now, being nearly all the data contradicts him -- he simply declares it's part of the conspiracy. He devolution to conspiracy cultist is complete.
As far as satellite temperature data goes, Carl Mears, the lead scientist for the RSS data set (the one so beloved by deniers), says that the surface data sets are more accurate,

A similar, but stronger case can be made using surface temperature datasets, which I consider to be more reliable than satellite datasets (they certainly agree with each other better than the various satellite datasets do!).

and that satellite data sets shouldn't be used to discuss climate.
Upper Air Temperature Remote Sensing Systems

All microwave sounding instruments were developed for day to day operational use in weather forecasting and thus are typically not calibrated to the precision needed for climate studies.

The surface data is better. It measures surface temperature directly instead of upper troposphere temperature, and it's far less twiddled and adjusted than satellite data. If you see someone using satellite data instead of surface data, you know you're looking at a fraud. Naturally, every denier relies solely on the satellite data.
