Anthony Watts has done it again and given the big boys a bloody nose – this time over the US temperature record.
NOAA announced today:
The average temperature for the contiguous U.S. during July was 77.6°F, 3.3°F above the 20th century average, marking the hottest July and the hottest month on record for the nation. The previous warmest July for the nation was July 1936 when the average U.S. temperature was 77.4°F. The warm July temperatures contributed to a record-warm first seven months of the year and the warmest 12-month period the nation has experienced since recordkeeping began in 1895.
Anthony had always wondered why NOAA didn’t provide data from the brand-spanking-new United States Climate Reference Network (USCRN). So he did it himself.
The difference is startling.
Using the old network, NOAA says the USA Average Temperature for July 2012 is: 77.6°F
Using the new NOAA USCRN data, the USA Average Temperature for July 2012 is: 75.5°F
The modern USCRN is 2.1°F cooler than the old problematic network.
It was no high record at all. To finish, Anthony delivers a funny, blistering rebuke.
NOAA never mentions this new pristine USCRN network in any press releases on climate records or trends, nor do they calculate and display a CONUS value for it. Now we know why. The new “pristine” data it produces is just way too cool for them.
