In addition to erroneously interpreting other results as indicative of the satellite data being wrong and the surface data right — a mistake the UA scientists attribute to the writers' lack of understanding of the scientific process' nuances — the Newsweek story wrongly stated that the satellite data didn't show signs of warming at the time the research was published.
"One of the more egregious errors in the Newsweek article is the misrepresentation of the satellite data relative to a January 2000 report from the National Academy of Sciences. That report did not 'skewer' the satellite data, as the Newsweek article contends. Instead, it found that the apparent disagreement between surface temperature records and the satellite record was not so significant as to invalidate either dataset," said Christy, who helped write the 2000 NAS report.
"The other Newsweek error, which has unfortunately been widely repeated, is that the satellite data were showing no warming at the time that research was published," Christy said. "That is not correct. By 2000 the satellite temperature dataset was clearly showing a long-term global warming trend, albeit a trend that was slightly less than the warming seen in surface data. That is still true today."
Oops. As Spencer, a research scientist at the Earth System Science Center, put it: "It is troubling that a major news organization devoting significant resources to a story about an important environmental issue would choose to cite data from seven years ago rather than current data, and would still get it wrong."
UPDATE: As John Laumer, one of our writers, noted in the comments, Roy Spencer has long been a prominent climate skeptic. John Christy, though also considered to be one, did help draft a statement by the American Geophysical Union in late 2003 concluding that "natural influences alone cannot explain the rapid increase in surface temperatures..."
We would thus caution readers to take their criticisms with a grain of salt (as will we) and to take Newsweek's article in good standing nonetheless.
