Power Line - Was 2010 the Warmest Year Ever?: "That didn't get the warmists where they were trying to go, so they have now changed the data by eliminating or drastically reducing the urban heat island effect. NASA now shows very different data for the period 1880-1999 from what it published in 1999. This animated GIF shows how the alarmists changed their own data to create the false impression of a climate crisis:
You probably assume that NOAA and NASA have made their raw data available to independent researchers, along with explanations of the adjustments they have made. But no--those agencies have resisted Freedom of Information Act requests for the original, raw data. One of the most important things the new Congress can do is to force these government agencies to level with the American people and explain the manipulations to which they have been subjecting weather data for years."
