“If mankind had never burned any coal, oil or natural gas, atmospheric CO2 levels would only be 30 to 50 ppmv lower than the current ~385 ppmv”
Got any proof of that? Seems like a “reasonable” statement to make, but “reasonable” isn’t scientific nor a fact.
The linked article is an extensive explanatory analysis of a paper published in the American Geophysical Union journal, Geophysical Research Letters.
Probably a bit more in the last few minutes.
My dog farted and then I did, to cancel his noxious odor...
Zip, zilch, nada.
Thanks for sharing.
“How much of the atmospheric CO2 is anthropogenic?”
It doesn’t matter. There is a mechanism for reestablishing CO2 equilibrium. Nature restores the balance.
Was that an eggplant, pickled egg and cheap beer fart? Or was that me?
So, greenhouse [effect] is all about carbon dioxide, right?
Wrong. The most important players on the greenhouse stage are water vapor and clouds.
Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.
In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).
The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Water Vapor Rules the Greenhouse System
Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.

Water Vapor Confirmed As Major Player In Climate Change
ScienceDaily (Nov. 18, 2008) -- Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.
That's exactly what this article says, too, per a peer- renewed Geophysical Research paper.
In a sane world, that should end the CO2 argument right there.
CO2 is only .04 percent of the total atmosphere.
The article doesn’t provide the paper or a link.
When are they going to ask how much of the carbon dioxide is hylogenic (caused by trees) or therogenic (caused by wild animals)?
It's mostly Bambi and Thumper's fault. The herbivores eat too much of the green plants, otherwise they would be getting rid of the carbon dioxide.
You smelt it...you dealt it....and you disgust me...sir...
Well that's embarrassing. No, it doesn't, but it quotes a paper. WTH?
I'll look for it, this is weird.
Global Warming is not due to human contribution of Carbon Dioxide - Global Warming: The Cold, Hard Facts? By Timothy Ball
No Smoking Hot Spot (The Australian)
Those two articles take Greenhouse Theory at face value and by the criterion set up in the theory itself finds no evidence of warming on the basis of greenhouse effect.
Sky-high hole blown in AGW theory?
"Forbes reports on a peer-reviewed study that uses NASA data to show that the effects of carbon-based warming have been significantly exaggerated. In fact, much of the heat goes out into space rather than stay trapped in the atmosphere, an outcome that started long before AGW alarmists predicted:"
That article explains why no Hot Spot has been found.
The Hidden Flaw in Greenhouse Theory
Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of Physics
Harvard astrophysicist dismisses AGW theory, challenges peers to 'take back climate science'
It Is Impossible For A 100 ppm Increase In Atmospheric CO2 Concentration To Cause Global Warming
Simple Chemistry and the Real Greenhouse Effect.
Those five articles each show that Greenhouse Theory has no basis in reality due to a direct conflict with the known laws of physics. No wonder the smoking gun "hotspot" can't be found.
