PART-1: NOAA REPORT AS SEEN ON USA TODAY 8/13/2021

July 2021 was the planet’s hottest month ever recorded, federal scientists announced Friday. Official global temperature records “only” date back 142 years, to 1880. But looking back further, the last time the world was definitely warmer than today was some 125,000 years ago, based on paleoclimatic data from tree rings, ice cores, sediments and other ways of examining Earth’s climate history, NASA climate scientist Gavin Schmidt said in 2017. National Oceanic and Atmospheric Administration Administrator Rick Spinrad, in a statement on Friday, said “in this case, first place is the worst place to be. July is typically the world’s warmest month of the year, but July 2021 outdid itself as the hottest July and month ever recorded. The combined land and ocean-surface temperature was 1.67 degrees Fahrenheit above the 20th-century average of 60.4 degrees F, according to NOAA. “This new record adds to the disturbing and disruptive path that climate change has set for the globe,” he said. According to NOAA, Asia had its hottest July on record, besting the previous record set in 2010; Europe had its second-hottest July on record – tying with July 2010 and trailing behind July 2018; and North America, South America, Africa and Oceania all had a top-10 warmest July. In the U.S., several states in the West and the northern Plains had their hottest July on record. A sign warns hikers of extreme heat on the salt flats of Badwater Basin in Death Valley National Park, Calif., where the temperature reached 128 degrees on July 10, according to the National Weather Service. July 2021 also marked the 45th consecutive July and the 439th consecutive month with temperatures, at least nominally, above the 20th-century average, NOAA said. NOAA’s report about July’s heat comes out the same week as a major report released by the Intergovernmental Panel on Climate Change. “Scientists from across the globe delivered the most up-to-date assessment of the ways in which the climate is changing,” Spinrad said. “It is a sobering IPCC report that finds that human influence is, unequivocally, causing climate change, and it confirms the impacts are widespread and rapidly intensifying.” ‘Code red for humanity’:UN report gives stark warning on climate change, says wild weather events will worsen Many of the changes seen in the world’s climate are unprecedented in thousands, if not hundreds of thousands, of years. Some of the changes already set in motion – such as a rise in sea levels – are irreversible over hundreds to thousands of years, according to the report. Due to human-caused climate change, Earth’s average temperature has risen more than 2 degrees Fahrenheit (1.2 degrees Celsius) since the late 19th century, NASA reported earlier this year. Ralf Toumi, co-director of Grantham Institute on climate change at Imperial College London, told Reuters the recent bursts of record-breaking heat are no surprise, given the long-term pattern of rising temperatures. “This is a constant casino we’re playing, and we’re just picking the high numbers again and again.

PART-2: CRITICAL COMMENTARY

IT IS REPORTED THAT THE GLOBAL MEAN SURFACE TEMPERATURE AND THE MEAN LAND SURFACE TEMPERATURE IN ASIA WERE THE HIGHEST TEMPERATURE IN THE INSTRUMENTAL RECORD SINCE 1880 AND THAT THE MEAN LAND TEMPERATURE IN EUROPE WAS THE SECOND HIGHEST OVER THE SAME PERIOD. THESE TEMPERATURES ARE THEN INTERPRETED IN TERMS OF ANTHROPOGENIC GLOBAL WARMING AS INDICATORS OF THE UNNATURAL AND DANGEROUS STRENGTH OF THE CURRENT WARMING CYCLE OF THE HOLOCENE THAT HAS BEEN ATTRIBUTED TO FOSSIL FUEL EMISSIONS.

WE NOTE IN THIS REGARD THAT THE THEORY OF ANTHROPOGENIC GLOBAL WARMING {AGW} REFERS ONLY TO LONG TERM TRENDS OF MORE THAN 30 YEARS IN GLOBAL MEAN SURFACE TEMPERATURE {GMST}, IN THAT CONTEXT, NEITHER THE LAND TEMPERATURE IN ASIA NOR THE LAND TEMPERATURE IN EUROPE HAS AN INTERPRETATION IN TERMS OF THE THEORY OF OF AGW. MOREOVER, THE THE MONTHLY MEAN TEMPERATURE IN THE MONTH OF JULY IS A BRIEF EVENT WITH A SPAN OF LESS THAN 30 YEARS AND THAT THEREFORE IT HAS NO INTERPRETATION IN TERMS OF AGW. WE PROPOSE THAT THESE TEMPERATURE EVENTS SHOULD BE UNDERSTOOD AS INTERNAL CLIMATE VARIABILITY AND NOT IN TERMS OF AGW.

RELATED POST ON INTERNAL CLIMATE VARIABILITY: LINK: https://tambonthongchai.com/2020/07/16/the-internal-variability-issue/ WE FIND STRONG SUPPORT FROM CLIMATE SCIENCE THAT A ONE MONTH TEMPERATURE EVENT MUST BE UNDERSTOOD AS INTERNAL CLIMATE VARIABILITY AND THAT IT THEREFORE DOES NOT HAVE AN AGW INTERPRETATION.

RELATED POST ON LONG TERM TRENDS IN GLOBAL MEAN SURFACE TEMPERATURE: LINK: https://tambonthongchai.com/2021/01/11/global-warming-dec2020/

IN THE LEFT FRAME WE DISPLAY LONG TERM TRENDS IN GMST FROM 1979 TO 2020 FOR ONE CALENDAR MONTH AT A TIME AND NOTE THAT ALL LONG TERM TRENDS OF 41 YEARS SHOW RELATIVELY STEADY WARMING TRENDS. IN THE RIGHT FRAME ARE DISPLAYED THE CORRESPONDING DECADAL TRENDS AND THESE APPEAR TO BE RANDOM. CLEARLY, DECADAL TRENDS IN GMST DO NOT HAVE AN AGW INTERPRETATION. WE CONCLUDE THAT EVEN DECADAL DATA, 10*12 = 120 MONTHS OF DATA, MUST BE UNDERSTOOD AS INTERNAL CLIMATE VARIABILITY AND THAT THEREFORE, THE OBSERVATION THAT THE MONTH OF JULY IN 2021, A SINGLE MONTH IN A SINGLE YEAR, WAS A PARTICULARLY HOT MONTH HAS NO INTERPRETATION IN TERMS OF AGW.

YET ANOTHER ISSUE IS THE USE OF A REFERENCE PERIOD THAT GOES BACK TO 1880. THIS TIME SPAN INCLUDES THE SO CALLED ETCW (EARLY TWENTIETH CENTURY WARMING) ANOMALY THAT CLIMATE SCIENCE HAS REMOVED FROM CONSIDERATION BECAUSE THIS WARMING SEQUENCE IS INCONSISTENT WITH AGW THEORY. JAMES HANSEN, NASA, AND CLIMATE SCIENCE IN GENERAL HAVE THEREFORE MOVED THE BEGINNING OF AGW TO THE POST ETCW YEAR OF 1950.

CONCLUSION: IN VIEW OF THE ARGUMENTS PRESENTED ABOVE WE FIND THE ALARM RAISED BY CLIMATE SCIENCE WITH RESPECT TO JULY MEAN TEMPERATURE IN 2021 IS INCONSISTENT WITH THE THEORY OF AGW AND THAT THEREFORE IT IS NOT CREDIBLE.

BRIEF TEMPERATURE EVENTS DO NOT HAVE AN AGW INTERPRETATION.

HUMAN CAUSE: THE REAL ISSUE HERE IS HUMAN CAUSE BECAUSE WITHOUT EVIDENCE OF HUMAN CAUSE OF THE WARMING TREND, WHATEVER IMPACTS THE WARMING MAY HAVE ARE ALL NATURAL.
