It’s official: 2015 ‘smashed’ 2014’s global temperature record. It wasn’t even close

Filed under: News

“2015 was by far the record year in all of the temperature datasets that are based on the instrumental and surface data,” said Gavin Schmidt, director of the Goddard Institute for Space Studies at NASA, which made the announcement jointly along with NOAA, the National Oceanic and Atmospheric Administration.

    This bugs me, because I am trained in meteorology, and support NOAA. The announcement was that 2015 was 1.62 F above the global 20th century average, but they obfuscate on exactly what that average is. That is the sort of thing that makes this into a “debate”, which it should not be. That, and constantly needing to adjust historical temperature measurements. One of the things I did for almost three decades was to take and to train others in taking accurate shipboard weather observations, which we did six times a day or more. The instruments were government owned, calibrated regularly, and located so that sun, wind, or other influences were minimized. Imagine hundreds of ships, constantly traveling the world, taking frequent and accurate measurements for at least a century. There is no good reason why those absolutely objective measurements should always need to be “adjusted”, and always in a direction to show a warming trend over time. I love objective data, and I try to base my beliefs on it. If NOAA uses a different methodology for measuring global temperatures every couple of years, They are never going to be able to demonstrate trends accurately. Especially when one is trying to explain that while the literal global temperatures as measured were higher in 1997 than in 2015, adjustments to data show a continued warming trend.
