“2014 was the planet’s warmest year on record,” President Obama proclaimed in his State of the Union speech. Obama cited the separate findings of two federal agencies, NASA and NOAA, which announced Jan. 16 that, “The Year 2014 ranks as the warmest since 1880.” To Obama, the record-breaking year is evidence Congress and the American people should rally round EPA’s greenhouse gas regulations.
When will the spinning end?
As is well-known, surface station records have many gaps (both spatial and temporal) and many quality-control issues. Moreover, they do not measure temperature in the troposphere – a more reliable indicator of atmospheric heat content and the greenhouse effect.
According to NOAA, the 2014 temperature in the troposphere was the third highest in the 1979-2014 record, as analyzed by the University of Alabama Huntsville (UAH) satellite program, and the sixth highest on record, as analyzed by the Remote Sensing Systems (RSS) satellite program.
So why don’t the agencies’ press releases proclaim 2014 the third or sixth warmest year? Or just say that it was one of the warmest in the instrumental record? Perhaps because “warmest on record” feeds the sense of crisis, which helps feed agency budgets. Notice the self-promotional aspect of NASA’s press release: “The observed long-term warming trend and the ranking of 2014 as the warmest year on record reinforces the importance for NASA to study Earth as a complete system, and particularly to understand the role and impacts of human activity.”
