PART-1: WHAT THE IPCC SAYS

Observed increases in well-mixed greenhouse gas (GHG) concentrations since around 1750 are
unequivocally caused by human activities.

PART-2: CRITICALCOMMENTARY

THE MOST FUNDAMENTAL DRIVING FORCE THAT RELATES GLOBAL WARMING TO FOSSIL FUEL EMISSIONS IS THE ASSUMPTION THAT OBSERVED CHANGES IN ATMOSPHERIC COMPOSITION ARE CAUSED BY FOSSIL FUEL EMISSIONS. YET, NO EVIDENCE IS PROVIDED FOR THIS CAUSATION. THIS ESSENTIAL RELATIONSHIP IN AGW THEORY IS ESTABLISHED ONLY WITH THE POWER OF THE WORD “UNEQUIVOCALLY”, ADMITEDDLY A VERY POWERFUL WORD, BUT THE POWER IN A SCIENTIFIC INVESTIGATION OF THIS NATURE SHOULD BE BASED ON DATA AND DATA ANALYSIS. FOR EXAMPLE, IT MUST BE SHOWN WITH DETRENDED CORRELATION ANALYSIS THAT ATMOSPHERIC COMPOSITION IS RESPONSIVE TO FOSSIL FUEL EMISSIONS AT THE PROPOSED TIME SCALE. IN A RELATED POST WE SHOW THAT NO SUCH CORRELATION IS FOUND IN THE DATA AND IN FACT, NO STATISTICAL SIGNIFICANCE IS FOUND FOR THE ASSUMED AIRBORNE FRACTION OF 50%.

CONCUSION: NO EMPIRICAL EVIDENCE IS FOUND IN THE DATA THAT ATMOSPHERIC COMPOSITION IS RESPONSIVE TO FOSSIL FUEL EMISSIONS. THIS ASSUMED CRITICAL RELATIONSHIP IN AGW THEORY IS ESTABLISHED IN THE IPCC REPORT NOT WITH EVIDENCE BUT WITH THE WORD “UNEQUIVOCALLY”.

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.
