I usually summarize topics gleaned from postings. But this one is written with a lot of interconnections from one of his 29 bullet points to another bullet point that segmenting it dilutes his reasoning. The source of this information is a posting, 11 March 2020, by Dr. Roger Higgs on the Electroverse web site.
29 BULLET POINTS PROVING THE SUN CAUSES GLOBAL WARMING, NOT CO2: BY A GEOLOGIST, FOR A CHANGE (DR ROGER HIGGS)
We urgently need to expose the ‘CO2 = pollutant’ fallacy being forced upon your children, grandchildren, nephews and nieces by schools, universities, governments and mainstream media worldwide, and to denounce it in scrupulously truthful terms easily understood by the public, including those youngsters themselves.
Here are the 29 bullet points proving CO2’s innocence:
1) The IPCC (United Nations Intergovernmental Panel on Climate Change) has no geologists among the hundreds of authors of its last major report (2013-14) and at most 1 geologist in the next report (due 2022; see my Technical Note 2019-10). Thus IPCC focuses on only the last 150 years (since thermometer records began, ~1850), yet Earth is 30 million (sic) times older, 4.5 billion years! Geologists know that Earth has warmed and cooled throughout this time. Climate change is perfectly normal.
2) The IPCC’s very existence relies on public belief in man-made- or ‘anthropogenic’ global warming (AGW) by carbon dioxide (CO2) emission. IPCC authors, mostly government and university researchers, are biased by strong vested interests in AGW (publications; continuance of salaries; research grants). Similarly, universities have sacrificed their impartiality by hosting institutes mandated to confirm and act on AGW, e.g. Grantham Institute (Imperial College), Tyndall Centre.
3) The claimed ‘97% consensus among scientists’ that AGW exists is a deception. It refers in fact to polls of recent publications by ‘climate scientists’, i.e. atmospheric scientists, lacking deep-time perspective (Bullet 1), whose numbers opportunistically exploded in the post-1990 AGW boom, creating a strong incentive for bias (Bullet 2).
4) No educated person ‘denies’ global warming: it has been measured (Bullet 11). ‘Global-warming denier’ and ‘Climate-change skeptic’ are deceitful terms for man-made-global-warming doubters and deniers (most of the world’s scientists?).
5) CO2 is a ‘greenhouse gas’. But, as CO2 rises, its theoretical heat-trapping ability sharply declines, already 67% ‘used up’ at 100 parts per million (ppm) CO2, 84% at 300 ppm (NB 275 ppm when industrial CO2 output began; Bullet 8), 87% at 400 ppm (today 415 ppm) and >99% at 1000 ppm. Moreover, Climate Sensitivity (CS), the warming due to doubling CO2, is guesswork. IPCC ‘estimates’ CS from climate models (circular reasoning) as probably between 1.5 and 4.5 (300% contrast!), but models are defective (Bullet 6). In reality CS might be very near zero, perhaps explaining why up to 7,000 ppm in Phanerozoic time (Bullet 7) did not cause ‘runaway’ warming.
6) Climate models (by climate scientists; Bullet 3) are so full of assumptions as to be useless or highly misleading, e.g. forecast 1995-2015 warming turned out to be 2 to 3 times too high. Bullet 19 gives another drastic failure. Even Wiki (2019) admits: “Each model simulation has a different guess at processes that scientist don’t understand sufficiently well”. Models dismiss the sun’s fluctuations and omit the multi-decade delay between these and resulting warming or cooling. This time-lag, due to ocean thermal inertia (mixing-time), is grossly underestimated by IPCC (Bullets 21, 22).
