claim: Satellite temperature readings going back to 1979 show 1998 was by far the warmest year in the satellite era
evidence: In January 2013 James Hansen and colleagues published their updated analysis that temperatures had continued at a high level despite strong La Nina conditions, and said the 5-year mean global temperature has been flat for a decade, which we interpret as a combination of natural variability and a slowdown in the growth rate of the net climate forcing, noting that the 10 warmest years in the record all occurred since 1998.
