As of last year, NOAA didnt show much, if any August warming for almost 20 years.

That didnt suit Barack Obamas agenda, so they simply changed the data to make the hiatus disappear.

This is on top of the massive data tampering they did prior to 2014.

Their graph looks nothing like satellite measurements of global temperature.

Their graph looks nothing like the 1975 NCAR graph, because they know that they can lie and cheat with impunity while Obama is in office.

NOAA has completely erased the 30 year cooling trend, and now simply fabricate imaginary data for the southern hemisphere.
