PART-1: WHAT THE REPORT SAYS

D.1.1 This Report reaffirms with high confidence the AR5 finding that there is a near-linear relationship
between cumulative anthropogenic CO2 emissions and the global warming they cause. Each 1000 GtCO2 of
cumulative CO2 emissions is assessed to likely cause a 0.27°C to 0.63°C increase in global surface
temperature with a best estimate of 0.45°C41. This is a narrower range compared to AR5 and SR1.5. This
quantity is referred to as the transient climate response to cumulative CO2 emissions (TCRE). This
relationship implies that reaching net zero42 anthropogenic CO2 emissions is a requirement to stabilize
human-induced global temperature increase at any level, but that limiting global temperature increase to a
specific level would imply limiting cumulative CO2 emissions to within a carbon budget.

PART-2: CRITICAL COMMENTARY#1

THE TCRE DERIVES FROM A LINEAR CORRELATION BETWEEN CUMULATIVE EMISSIONS AND SURFACE TEMPERATURE AND AS EXPLAINED IN A RELATED POST ON THIS SITE: LINK: https://tambonthongchai.com/2020/08/26/a-mathematical-inconsistency/ IT VIOLATES THE FUNDAMENTAL THEORY OF ANTHROPOGENIC GLOBAL WARMING DRIVEN BY THE GREENHOUSE EFFECT OF ATMOSPHERIC CARBON DIOXIDE. IN THE TCRE, SURFACE TEMPERATURE IS A LINEAR FUNCTION OF CUMULATIVE EMISSIONS BUT IN THE THEORY OF ANTHROPOGENIC GLOBAL WARMING DRIVEN BY THE GREENHOUSE EFFECT OF ATMOSPHERIC CO2 CONCENTRATION, THE SURFACE TEMPERATURE IS A LOGARITHMIC FUNCTION OF CUMULATIVE EMISSIONS. THIS MATHEMATICAL INCONSISTENCY INVALIDATES THE THEORY OF ANTHROPOGENIC GLOBAL WARMING PRESENTED BY THE IPCC ON BEHALF OF CLIMATE SCIENCE.

THE REASON CLIMATE SCIENCE PREFERS THE TCRE FOR COMPUTIONAL PARAMETERS SUCH CARBON BUDGETS AND THE PRESENTATION ABOVE IS THAT THE THEORETICAL PARAMETER, THE ECS CLIMATE SENSITIVITY, REMAINS AN UNSETTLED ISSUE IN CLIMATE SCIENCE BECAUSE THEY DON’T REALLY KNOW WHAT ITS VALUE IS EXACTLY – AS DESCRIBED IN THIS RELATED POST:

THESE KINDS OF STATISTICAL AND MATHEMATICAL ERRORS ARE THE NORM 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.
