[Politically Correct]

It is weird that nobody has the original data that is in question. They are supposedly independent research centers. They seem to be using the same source for bogus data.

The NASA satellite data is calibrated from the CRU data........starting to get the picture?

“They seem to be using the same source for bogus data.”

“The NASA satellite data is calibrated from the CRU data.”

Some errors to correct here:
- NASA GISS is not satellite data (strange but true),
http://data.giss.nasa.gov/gistemp/station_data/
- the satellite data is UAH (U Alabama Huntsville)
- The satellite data nor GISS is NOT calibrated from CRU data
- There are 4 main datasets - NASA/GISS, Hadley, CRU, UAH
- There are adjustments done within each dataset, not between them

The REAL issue with GISS and CRU is the adjustments for Urban Heat Island or other effects. If they are ‘massaging’ the data wrong, the numbers they report are wrong. This cant be checked unless they make public the raw data, and the adjustments.
