NOAA Temperature Fraud Expands (Part 1) | Real Science
The current NOAA claim is that 2012 is 1.0 degrees Fahrenheit warmer than 1998, but 1934 used to be 1.1 degrees Fahrenheit warmer than 1998. This means that prior to adjustment, 1934 was hotter than 2012.
The blink comparator below shows the huge changes which have been made to the US temperature record since 1999. The past has been massively cooled, and the present has been massively warmed. A cooling trend has been turned into a warming trend, by adjusting the data.
