Weather data at Washington’s Reagan National Airport fiddled
The National Weather Service swapped out the sensor within a week and found that the old one was reading 1.7 degrees too high. Close enough to 2.1, the observed difference. But the National Weather Service told the Capital Weather Gang that there will be no corrections, despite the fact that the disparity suddenly began 19 months ago and varied little once it began. It said correcting for the error wouldn't be "scientifically defensible." Therefore, people can and will cite the May record as evidence for dreaded global warming with impunity.
Are political considerations superseding scientific ones at the National Oceanic and Atmospheric Administration?
When confronted with an obviously broken weather station that was reading way too hot, they replaced the faulty sensor — but refused to adjust the bad readings it had already taken. And when dealing with “the pause” in global surface temperatures that is in its 19th year, the agency threw away satellite-sensed sea-surface temperatures, substituting questionable data that showed no pause.
Unfortunately, following this with the kerfuffle over the Reagan temperature records is only going to “convince” even more people that our government is blowing hot air on global warming.
