You left out "altered to fit the model" -- which is, of course, hideously bad science.The NCDC publishes great media:
Global Climate Change Indicators
How do we know the Earth's climate is warming?
Thousands of land and ocean temperature measurements are recorded each day around the globe. This includes measurements from climate reference stations, weather stations, ships, buoys and autonomous gliders in the oceans. These surface measurements are also supplemented with satellite measurements.
These measurements are processed, examined for random and systematic errors, and then finally combined to produce a time series of global average temperature change.
