New Extreme Weather Record? Not So Fast.

Jeff Masters, a meteorologist and a co-founder of Climate Underground, an internet information service, says the rationale extra temperature data are usually not overturned is as a result of the method is simply too time-consuming. A living proof, he stated, is that an effort to reanalyze each named Atlantic storm since 1851, which started 20 years in the past, has up to now reached solely the 12 months 1965.

“There are a whole bunch of temperature data within the U.S. alone that might not survive a re-analysis,” Dr. Masters stated. “Probably the most well-known of those is the world-record hottest temperature in historical past of 134 levels Fahrenheit in 1913 in Demise Valley.”

Two excessive climate specialists, William T. Reid and Christopher C. Burt, have argued on the Climate Underground web site that the 1913 studying was “not potential from a meteorological perspective,” partially as a result of it was not in keeping with different observations made in that a part of Demise Valley over the identical week. They are saying the person who recorded the temperature, at Greenland Ranch in California, seems on reflection to have “knowingly or inadvertently” exaggerated the studying, and that he could not have even been current on the time.

However Randall Cerveny, who leads the World Meteorological Group’s efforts to analysis and confirm international climate data, stated in an e-mail that the 1913 studying was nonetheless acknowledged because the “hottest temperature recorded for the USA and for the world.”

Dr. Cerveny, who teaches geographical sciences at Arizona State College and labored with Mr. Burt to debunk the 1922 Libya document, described the analysis on the 1913 Demise Valley document by Mr. Burt and Mr. Reid as “conjectural, not new proof.” He added that the U.S. Local weather Extremes Index, a NOAA undertaking, has additionally opted to not examine it.

“We don’t dismiss data with out substantial proof proving their inaccuracy,” he stated.

As for newer Demise Valley data, Dr. Cerveny stated the W.M.O. was nonetheless attempting to confirm a 129.9-degree studying from that space on Aug. 6, 2020.

If confirmed, it will be the third-highest temperature ever recorded on Earth and the second-highest in the USA. However Dr. Cerveny stated the investigation is “taking some time” as a result of his workforce has been testing the temperature sensor that made the studying.
