Last year will be remembered as the year when NOAA and NASA quit making any attempt to appear legitimate, and simply started making up data to suit the needs of the White House
The signature is easy to see in the graph above. ENSO events get amplified in the troposphere, and TLT temperatures make much larger swings than surface temperatures during El Nino and La Nina events. You can see this in the 2008 La Nina an 2010 El Nino below. Now look at the 2015 El Nino. GISS surface temperatures have swung much higher than troposphere temperatures, which defies physics. This is a smoking gun that the NASA surface data is fake.
