Until last week, government data on climate change indicated that the Earth has warmed over the last century, but that the warming slowed dramatically and even stopped at points over the last 17 years.
But a paper released May 28 by researchers at the National Oceanic and Atmospheric Administration has readjusted the data in a way that makes the reduction in warming disappear, indicating a steady increase in temperature instead. But the study’s readjusted data conflict with many other climate measurements, including data taken by satellites, and some climate scientists aren’t buying the new claim.
“While I’m sure this latest analysis from NOAA will be regarded as politically useful for the Obama administration, I don’t regard it as a particularly useful contribution to our scientific understanding of what is going on,” Judith Curry, a climate science professor at Georgia Tech, wrote in a response to the study.
And in an interview, Curry told FoxNews.com that that the adjusted data doesn’t match other independent measures of temperature.
“The new NOAA dataset disagrees with a UK dataset, which is generally regarded as the gold standard for global sea surface temperature datasets,” she said. “The new dataset also disagrees with ARGO buoys and satellite analyses.”
Skeptics say there are yet more measurements, including those coming from balloon data, that line up with existing data more than with Karl’s newly adjusted data. They also note that even with Karl’s adjustments, the warming trend he finds over the last 17 years is below what U.N. models had predicted.
But skeptics say Karl’s adjusted data is the outlier that conflicts with everything else.
“Color me ‘unconvinced’,” Curry wrote.
