I stopped paying attention to global temperature when the data I was using was changing every time I compared it with earlier data from the same source.
Just for your own files, this is the satellite data that doesn't need to average thousands of thermometers around the world.
I know data. I don't see the rising wavy line created to fit the data. I see two straight lines. One from 1979 to1997 and one from 1999 to 2011 separated by .3 of a degree C over a total of 30 years.
