It's true.
Here's the old data with the fabricated data points (http://data.giss.nasa.gov/gistemp/graphs_v3/Fig.D.gif)
Here's the graph with the actual data (http://www.giss.nasa.gov/research/briefs/hansen_07/fig1x.gif)
...in recent years, NOAA’s US Historical Climatology Network (USHCN) has been “adjusting” its record by replacing real temperatures with data “fabricated” by computer models. The effect of this has been to downgrade earlier temperatures and to exaggerate those from recent decades, to give the impression that the Earth has been warming up much more than is justified by the actual data.
These show that the US has actually been cooling since the Thirties, the hottest decade on record; whereas the latest graph, nearly half of it based on “fabricated” data, shows it to have been warming at a rate equivalent to more than 3 degrees centigrade per century.
