Hi kenzrw, NASA uses raw temperature data from NOAA. You can learn more from RealClimate, particularly this post (see "Mistaken Assumption #3).

If I trusted any organization in its ability to correctly determine the planet-wide temperature, it'd be NOAA. NOAA and its predecessor Weather Bureau has been around since 1870 and knows how to take and record temperatures. Let's be careful that we don't over-hype current computer models from NASA and others when they simulate and average-out worldwide temperatures. We need to be careful that we don't change past temperature readings just to fit some current computer model, and I trust NOAA not to do this more than the other two organizations.

I was with you until you said the warming is caused by increasing levels of greenhouse gases due to human activities. It seems that CO2 really does not significantly affect the global temperature. Please see the report of Dr David Evans discussing why it was thought CO2 was the cause but now it cannot be based on better data (higher resolution ice samples and satellite data showing that the CO2 hypothesis does not match the actual heat patterns.

New more accurate data can wipe out old obsolete data in one fell swoop. The old ice core data had only invervals of around 1000 years and it was ASSUMED CO2 was the cause. You know what assume spells.
