Satellite temperature readings going back to 1979 show 1998 was by far the warmest year in the satellite era, followed by 2010. 2015 comes in third. And these results are only for the period since 1979.
You can see immediately that 2014 is not the hottest year among even the last 18 years. Not by a long shot. Why is this chart be so different from the widely reported announcement in January by NOAA and NASA that 2014 was the hottest ever (“ever” being just since 1880, when records began)?
