NASA used to correctly show that the 1930s and 1950s were the warmest decades in the US.
in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country (Figure 2).
But around the year 2000, they made the decision to alter the data, in order to create a non-existent warming trend.

In the private sector, this sort of behavior is normally prosecuted – but in government you get rewarded with funding and prestige for generating fake data which suits the political objectives of Washington DC.
