Mind you the lying liars at NASA have done this stuff before. McIntyre has also shown they added 0.15 degrees (Celsius scale) to every temperature reading in the USA from 2000 to at least 2007 for no reason at all. Subsequently, NASA Goddard pulled the data and blamed NOAA (the nationalist socialist oceanic and atmospheric administration) for the error. Then claimed an unusual hotspot in the Arctic, in spite of 30% heavier sea ice than last year.
Why lie? Because these scum get more money from government if you buy into their lies about global warming. NASA delenda est
