Interesting. NOAA accused of cooking the books by other scientists.
Watts Up With That is a known anti-climate change organisation which was originally formed with the remit to disrupt climate science and has a history of causing major problems to legitimate, and peer-reviewed (and accepted) science (it was one of the key drivers of 'Climategate', which ended up being refuted by multiple scientific sources and independent review panels, but caused excessive reputational damage at the time). It's very biased.
For example, the article describes Anthony Watts (WUWT's founder) as a 'meteorologist'. It's true that he was a television/radio meteorologist (aka 'weather reporter), and he has worked for Fox in a 'chief meteorologist' role. However, he has taken a couple of university classes in meteorology but has not completed a full qualification in the subject.*
It also describes Bob Tisdale as a 'climate expert', but to the best of my knowledge, no-one has a clue what his qualifications are. I remember him as the guy who claimed the IPCC had done no research into the natural causes of climate change, which is easy to refute if anyone's ever read any of the IPCC's reports on climate change, and I've scientists of several different disciplines (not just climatologists) question his qualifications on the grounds that his books and reports appear to show little understanding of science at all.
It'll be interesting to see if independent scientific sources can verify this. Watts has been objecting to NOAA's doubling trend research since 2012, and climatologists have been finding serious flaws in WUWT's research and grasp of the science concerned ever since 2012 - that includes some other climate sceptics (such as Stephen MacIntyre who distanced himself from WUWT's 2012 criticism of NOAA's research on this subject, agreeing with the criticism by climatologists). You definitely will need a more unbiased source than this one.* For the record, I have also taken university classes in meteorology, which makes me about as educated as Watts on the subject.
