In face of intense criticism from alarmist scientists, Dr. John Christy went to great lengths in a Tuesday congressional hearing to detail why satellite-derived temperatures are much more reliable indicators of warming than surface thermometers.
“That’s where the real mass of the climate system exists in terms of the atmosphere,” Christy, a climate scientist at the University of Alabama and Alabama’s state climatologist, said in a Wednesday hearing before the House science committee.
“When a theory contradicts the facts” you need to change the theory, Christy said. “The real world is not going along with rapid warming. The models need to go back to the drawing board.”
Texas Republican Rep. Lamar Smith, the committee’s chairman, convened a hearing on the implications of President Barack Obama’s recent United Nations deal in Paris, which agreed to cut carbon dioxide emissions.
Christy doesn’t think signing onto a U.N. deal is good for Americans, and challenges the very data politicians and environmentalists rely on to push green energy policies.
“One of my many climate interests is the way surface temperatures are measured and how surface temperatures, especially over land, are affected by their surroundings,” Christy wrote in his prepared testimony.
Christy recently co-authored a study with veteran meteorologist Anthony Watts that found the National Oceanic and Atmospheric Administration (NOAA) was basing its temperature adjustments on “compromised” temperature data.
The study found most of NOAA’s 1,218 thermometers were sited near artificial surfaces and heat sources like concrete, asphalt, and air conditioner exhausts that were causing more warming to show in the U.S. temperature record than was present at weather stations that were well-sited.
Christy and Watts surmised NOAA was basing its temperature adjustments (efforts made to get “biases” out of the temperature record) on bad data.
