With their latest subpoena to the Obama administration, House Republicans risk descending into a rabbit hole, albeit a useful one.
Lamar Smith, the Texas GOPer who runs the House science and technology committee, has been seeking, voluntarily and then not so voluntarily, emails and other internal communications related to a study released earlier this year by the National Oceanic and Atmospheric Administration. The study, by adjusting upward temperature readings from certain ocean buoys to match shipboard measurements, eliminated the “pause” in global warming seen in most temperature studies over the past 15 years.
Let’s just say, without prejudging the case, gut instinct has always indicated that, if there’s a major global warming scandal to be discovered anywhere, it will be found in the temperature record simply because the records are subject to so much opaque statistical manipulation. But even if no scandal is found, it’s past time for politicians and the public to understand the nature of these records and the conditions under which they are manufactured.
This is where those who confuse science with religion, and scientists with priests, take umbrage. Unfortunately, NOAA has proved itself pliable to the propagandizing urge. Witness its steady stream of press releases pronouncing the latest month or year the “warmest on record.” It always falls to outsiders to point out that these claims often rest on differences many times smaller than NOAA’s own cited margin of error. Case in point: When President Obama declared in January that 2014 was the warmest year on record, it had only a 38% chance of being hotter (by an infinitesimal margin) than other hottest-year candidates 2010, 2005 and 1998.
