That's a 10-year rolling average to smooth out the noise in the data. You can see what Karoly et. al. suggest is a natural warming trend for the first half of the 20th century, and our greenhouse handiwork for the more recent half century.

The full GISS data set is here if you want to pull it down and play with it yourself.
