In 2012, I wrote an American Thinker article on the status of global warming at the time. I used the latest available NASA/GISS data to do that analysis, which was the version NASA had on its website on April 30, 2012 (Land-Ocean Temperature Index [LOTI]).
At that time, the data from 1880 through 2011 showed a warming trend of 0.59 degrees Celsius per century.
What is that warming trend using the latest data from NASA's website (December 30, 2017), using those same exact years (1880-2011)? The answer is 0.66? C.
How did warming accelerate if we are looking at the very same years?
Apparently, the Earth is getting warmer faster than it was five and a half years ago, but not because of actual recorded thermometer readings in those last five and a half years. It is getting warmer faster because NASA adjusted the data to show faster warming.
