Some heated claims were made in a recently published scientific paper, “Recent Global Warming as Confirmed by AIRS,†authored by Susskind et al. One of the co-authors is NASA’s Dr. Gavin Schmidt, keeper of the world’s most widely used dataset on global warming.
Press coverage for the paper was strong. ScienceDaily said that the study “verified global warming trends.†U.S. News and World Report’s headline read, “NASA Study Confirms Global Warming Trends.†A Washington Post headline read, “Satellite confirms key NASA temperature data: The planet is warming -- and fast,†with the author of the article adding, “New evidence suggests one of the most important climate change data sets is getting the right answer.â€
The new paper uses the AIRS remote sensing instrument on NASA’s Aqua satellite. The study describes a 15-year dataset of global surface temperatures from that satellite sensor. The temperature trend value derived from that data is +0.24 degrees Centigrade per decade, coming out on top as the warmest of climate analyses.
Oddly, the study didn’t compare two other long-standing satellite datasets from the Remote Sensing Systems (RSS) and the University of Alabama at Huntsville (UAH). That’s an indication of the personal bias of co-author Schmidt, who in the past has repeatedly maligned the UAH dataset and its authors because their findings didn’t agree with his own GISTEMP dataset. In fact, Schmidt’s bias was so strong that when invited to appear on national television to discuss warming trends, in a fit of spite, he refused to appear at the same time as the co-author of the UAH dataset, Dr. Roy Spencer.
