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.
The NOAA report appears to have been another salvo in the White House’s attempt to regain the offensive, ahead of the Heartland Institute’s Tenth International Climate Conference. However, a growing number of prominent analysts have uncovered serious biases, errors and questions in the report.
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)?
The data may show Earth experienced its hottest year on record in 2014, but that would not be proof humans are causing global warming. It wouldn’t even prove the year was the hottest on record, or even particularly hot.
