I believe in mathematics. Not junk climate science.

In my previous blog post, I reported that October-March afternoon temperatures were third coldest on record in the US. Bob Ward angrily responded with :

“utter BS. NOAA recorded the six months to the end of February as the 35th warmest on record.”

Bob Ward on Twitter: “As usual, your claims are utter BS

Bob made two major mistakes. First he used the wrong six month period, Sep-Feb instead of Oct-Mar. But his big mistake is using the words “NOAA recorded.” He should have said “NOAA reported.” NOAA massively alters their recorded data before they report it.

Here are the NOAA recorded average daily maximum temperatures, third coldest :

Here are the NOAA recorded average monthly maximum temperatures, third coldest :

Here are the NOAA reported average monthly maximum temperatures, 31st coldest :

Here are the NOAA adjustments to average monthly maximum temperatures, 2nd largest :

About 43% of the data NOAA used in the their adjusted calculation was fabricated by computer model, rather than record – the largest percentage of fake data on record. The fake data is marked with an “E” in the NOAA text files.

Spreadsheet

All of the data is taken directly from the NOAA ftp site. I challenge Bob to prove me wrong.
