The National Oceanic and Atmospheric Administration, criticized for manipulating temperature records to create a warming trend, has now been caught warming the past and cooling the present.
July 2012 became the hottest month on record in the U.S. during a summer that was declared “too hot to handle” by NASA scientists. That summer more than half the country was experiencing drought and wildfires had scorched more than 1.3 million acres of land, according to NASA.
According to NOAA’s National Climatic Data Center in 2012, the “average temperature for the contiguous U.S. during July was 77.6°F, 3.3°F above the 20th century average, marking the warmest July and all-time warmest month on record for the nation in a period of record that dates back to 1895.
“The previous warmest July for the nation was July 1936, when the average U.S. temperature was 77.4°F,” NOAA said in 2012.
This statement by NOAA was still available on their website when checked by The Daily Caller News Foundation. But when meteorologist and climate blogger Anthony Watts went to check the NOAA data on Sunday he found that the science agency had quietly reinstated July 1936 as the hottest month on record in the U.S.
“Two years ago during the scorching summer of 2012, July 1936 lost its place on the leaderboard and July 2012 became the hottest month on record in the United States,” Watts wrote. “Now, as if by magic, and according to NOAA’s own data, July 1936 is now the hottest month on record again. The past, present, and future all seems to be ‘adjustable’ in NOAA’s world.”
Watts had data from NOAA’s “Climate at a Glance” plots from 2012, which shows that July 2012 was the hottest month on record at 77.6 degrees Fahrenheit. July 1936 is only at 77.4 degrees Fahrenheit. [Annotations in the graph are from Watts].
Watts ran the same data plot again on Sunday and found that NOAA inserted a new number in for July 1936. The average temperature for July 1936 was made slightly higher than July 2012, meaning, once again, July 1936 is the hottest year on record. [Annotations in the graph are from Watts]
“You can’t get any clearer proof of NOAA adjusting past temperatures,” Watts wrote. “This isn’t just some issue with gridding, or anomalies, or method, it is about NOAA not being able to present historical climate information of the United States accurately.”
“In one report they give one number, and in another they give a different one with no explanation to the public as to why,” Watts continued. “This is not acceptable. It is not being honest with the public. It is not scientific. It violates the Data Quality Act.”
Watts’ accusation of NOAA climate data manipulation comes after reports that the agency had been lowering past temperatures to create a warming trend in the U.S. that does not exist in the raw data.
The ex-post facto data manipulation has been cataloged by climate blogger Steven Goddard and was reported by the UK Telegraph earlier this month.
“Goddard shows how, in recent years, NOAA’s US Historical Climatology Network (USHCN) has been ‘adjusting’ its record by replacing real temperatures with data ‘fabricated’ by computer models,” writes Christopher Booker for the Telegraph.
“The effect of this has been to downgrade earlier temperatures and to exaggerate those from recent decades, to give the impression that the Earth has been warming up much more than is justified by the actual data,” Booker writes. “In several posts headed ‘Data tampering at USHCN/GISS,’ Goddard compares the currently published temperature graphs with those based only on temperatures measured at the time.
“These show that the US has actually been cooling since the Thirties, the hottest decade on record; whereas the latest graph, nearly half of it based on ‘fabricated’ data, shows it to have been warming at a rate equivalent to more than 3 degrees centigrade per century,” Booker adds.
When asked about climate data adjustments by the DCNF back in April, NOAA send there have been “several scientific developments since 1989 and 1999 that have improved the understanding of the U.S. surface temperature record.”
“Many station observations that were confined to paper, especially from early in the 20th century, have been scanned and keyed and are now digitally available to inform these time series,” Deke Arndt, chief of NOAA’s Climate Monitoring Branch, told TheDCNF.
“In addition to the much larger number of stations available, the U.S. temperature time series is now informed by an improved suite of quality assurance algorithms than it was in the late 20th Century,” Deke said in an emailed statement.
But NOAA has apparently not just been adjusting temperatures downward, but also adjusting them upwards.
“This constant change from year to year of what is or is not the hottest month on record for the USA is not only unprofessional and embarrassing for NOAA, it’s bullshit of the highest order,” Watts wrote. “It can easily be solved by NOAA stopping the unsupportable practice of adjusting temperatures of the past so that the present looks different in context with the adjusted past and stop making data for weather stations that have long since closed.”
NOAA did not immediately respond to TheDCNF’s request for comment.
