Now that you've confessed you can't understand the graphs, I'll help you out: The first graph contrasts global temperatures measured by NASA's satellites (rss) with the NASA GISS (gistemp) surface temperatures. One shows a warming over the past 12+ years, the other a cooling trend. Which is right? Well look at the next graph gif which contrasts GISS at various points in the past - 1981, 2002, and 2014. You can see that the shape of the graph and the magnitude of temperature changes has been changed over to magnify warming. In 1981, GISS said 1940 was warmer 1980, that had changed by 2002 and changed even more by 2014. There's no good reason for that. In 1981, there was a significant decline in temperatures between 1940 and 1970, but in later years this decline was leveled out and reduced. The 1975 NAS graph is another historic temperature chart that verifies the shape of the 1981 GISS chart. Thus you can see with your own eyes that GISS has altered historic temperatures. Now try deny anything I said here.
