Geologist Dr. Ian Plimer counters USA Today’s ‘fact-check’ on CO2 levels: Media’s ‘fact-checking resorted to lies & omissions’

Special to Climate Depot

Media Claim: Climate skeptic’s claims about CO2 levels, ice ages, and animals misleads. Fact check (by Kate S. Petersen, USA TODAY)

The article claims, “Neither Plimer nor the social media user responded when USA TODAY asked which “six great ice ages” they were referencing.”

That is a lie. USA TODAY did not contact me despite the fact that I am easily contactable.

USA TODAY’s fact checks state that “Human greenhouse gas emissions, not El Niño, drive climate change”. Nowhere have I claimed El Niño drives climate change, and it has never been shown that human emissions drive global warming. If it could be shown, then it would also have to be shown that the modern warming is completely different from previous warming. This has not been done.

USA TODAY’s fact checks state that “Greenhouse gases, not Milankovitch cycles, drives modern global warming”. This is contrary to data on the Earth’s orbit, solar activity and plate tectonics. Furthermore, it was never been shown that greenhouse gases drive climate change.

USA TODAY’s fact checks state that “Humans are responsible for a significant amount of CO2 in the atmosphere.” If one molecule of plant food in 83,333 molecules in the atmosphere is a significant amount, then I’m a monkey’s uncle. It would also have to be shown that the molecules of plant food of natural origin do not drive global warming.

USA TODAY’s rating of a talk I gave was “Partly false” regarding six major ice ages, and then played semantic games as to whether an ice age or a glaciation within an ice age could be considered an ice age.

The key points of my talk were not addressed. These were:

(a)   Ice ages and glaciations were initiated when the atmospheric carbon dioxide content was far higher than today (e.g. Huronian, Cryogenian, Permo-Carboniferous) hence, atmospheric carbon dioxide could not drive global warming.

(b)  Increases in atmospheric temperature are followed by an increase in atmospheric carbon dioxide, which is the opposite of the climate activist mantra that suggests an increase in atmospheric carbon dioxide drives global warming.

(c)   For decades, I have asked climate activists to give me half a dozen scientific papers that show unequivocally that human emissions of carbon dioxide drive global warming. This has not been done.

It appears that fact-checking resorted to lies and omissions of pertinent information. Ideologically-blessed activist fact checkers with no scientific training give little confidence.
