I’ve updated NASA’s surface temperature graphs to include their latest 2015 fraud. You can see how they have doubled 1880-1980 warming since their 1982 version, and are continuing to continuing to cool the past and add additional fraud on to all of their post 1980 temperatures, every year.

All global warming over the past 19 years is due to data tampering by criminals at government agencies, and long term warming has been more than doubled since 1982 by these same criminals.
