IPCC6 POST#2: PRE-INDUSTRIAL

Posted on: August 10, 2021

PART-1: WHAT THE REPORT SAYS

Observed increases in well-mixed greenhouse gas (GHG) concentrations since around 1750 are unequivocally caused by human activities. Since 2011 (measurements reported in AR5), concentrations have continued to increase in the atmosphere, reaching annual averages of 410 ppm for carbon dioxide (CO2), 1866 ppb for methane (CH4), and 332 ppb for nitrous oxide (N2O) in 2019. Land and ocean have taken up a near-constant proportion (globally about 56% per year) of CO2 emissions from human activities over the past six decades, with regional differences. Each of the last four decades has been successively warmer than any decade that preceded it since 1850. Global surface temperature in the first two decades of the 21st century (2001-2020) was 0.99 °C higher than 1850-1900. Global surface temperature was 1.09C higher in 2011-2020 than 1850–1900. The estimated increase in global surface temperature since AR5 is due to methodological advances and new datasets that contributed 0.1ºC .

PART-2: CRITICAL COMMENTARY

HERE WE FIND THAT ATMOSPHERIC COMPOSITION IS BEING COMPARED WITH A HISTORICAL PERIOD GOING BACK TO 1750 AND THE SURFACE TEMPERATURE IS BEING COMPARED WITH A HISTORICAL PERIOD GLOING BACK TO 1850-1900. AT THE SAME TIME, THE CLIMATE SCIENCE POSITION IS THAT ANTHROPOGENIC GLOBAL WARMING STARTED IN 1950. THIS MORE RECENT REFERENCE YEAR IS JUSTIFIED IN CLIMATE SCIENCE IN TERMS OF WHAT IS CALLED THE ETCW ISSUE IN CLIMATE SCIENCE – EARLY TWENTIETH CENTURY WARMING – DESCRIBED IN DETAIL WITH A BIBLIOGRAPHY IN A RELATED POST LINKED BELOW

IN ESSENCE, THE ETCW ISSUE IS THAT THE CLIMATE SCIENCE GHG THEORY OF GLOBAL WARMING THAT RELATES TEMPERATURE TO ATMOSPHERIC CO2 CONCENTRATION DOES NOT WORK IN THE PERIOD 1750-1950 OR FROM 1850 TO 1950 OR FROM 1900 TO 1950 AND LATER BECAUSE THE EARLY TWENTIETH CENTURY WARMING IS TOO STRONG TO BE DESCRIBED IN TERMS OF THE GHG EFFECT OF ATMOSPHERIC CO2 CONCENTRATION. CLIMATE SCIENCE HAS RESPONDED TO THIS ISSUE NOT WITH A SCIENTIFIC EXPLANATION BUT BY SIMPLY REMOVING THE DIFFICULT DATA FROM FURTHER CONSIDERATION AND SIMPLY MOVING THE “PRE-INDUSTRIAL” YEAR WHEN GLOBAL WARMING BEGAN TO THE YEAR 1950. IT APPEARS THAT THE IPCC SCIENTISTS ARE NOT AWARE OF THIS VERY SIGNIFICANT ISSUE IN CLIMATE SCIENCE.

THE BLIND WORSHIP OF THE IPCC AS SOME KIND OF SCIENTIFIC AUTHORITY OVERLOOKS THE REALITY THAT THE IPCC IS AN AGENCY OF THE UN AND THEIR BOSS IS ANTONIO GUTERRES; MEANING THAT THEIR SCIENCE MUST MEET THE REQUIREMENTS OF UN BUREAUCRATS.
