The effectiveness of CO2 as a greenhouse gas becomes ever more marginal with greater concentration — ‘The effectiveness of CO2 as a greenhouse gas diminishes logarithmically with increasing concentration and from the current level of ~390 ppmv, (parts per million by volume). Accordingly only ~5% of the effectiveness of CO2 as a greenhouse gas remains beyond the current level’

Warmists Claim: ‘Carbon dioxide and global warming: More is NOT better’ – ‘Then there’s the problem of rate. Sure, CO2 levels were higher in the past. But it’s not just the amount the counts, it’s how quickly it rose to that amount. Solid research done over the past few years has shown that the current rate of increase of CO2 in the atmosphere is entirely unprecedented over at least the past 11,000 years (and almost certainly much farther back than that). There were times in the past when the amount was higher, but it took millennia to reach those levels. We’re about to blow through the record like a rocket, and we’ve done it in a mere century.’
Rebuttal: Princeton physicist Dr. William Happer responds to alleged ‘rapid change’ argument:
Happer: ‘The argument that plants and animals cannot adapt to rapid change is largely baloney. There are enormous changes in temperature from summer to winter, in humidity from wet seasons to dry season, from very alkaline, warm ocean surface water in the tropics to cold, much less alkaline deep waters, to nearly pH neutral waters off landmasses bordering the arctic. As I have measured many times, simply walking out of a Princeton lecture hall to the open air, can change the CO2 concentration from 1200 ppm in the hall to 450 ppm outside. The same transit commonly goes with a temperature change of 10 C or more. Greenhouse operators change CO2 concentrations from ambient, say 400 ppm, to 2000 ppm in 15 minutes — with absolutely no ill effects to the plants. The CO2 concentrations in a corn field can change from under 300 ppm or less at noon to 600 ppm or more at midnight, depending on wind conditions.
Alas, rational arguments with committed warmists help no more than economic arguments used to work with committed Soviet Marxists. They used to cite hundreds of peer reviewed papers to prove how well socialism worked and how it would soon bury outmoded capitalism. One can easily find similar examples of self-deception by right-wing apparatchiks. So this seems to be a bug in whatever program controls the human mind. Madison, Hamilton and Jay clearly understood the problem, self interest, which they assumed would always trump reason, honor, decency, etc.
In writing the US Constitution, they tried to work around this lamentable flaw of the human mind, which is easy to ignore, or to rationalize as a virtue.

UN freakout at 400 ppm CO2: World in ‘new danger zone.’ What a difference 1 ppm makes!
Warmist Media Matters Upset at media for quoting Climate Depot: Climate Change, ‘Happy Plants,’ And False Balance – ‘Bloomberg News Gives Equal Weight To Climate Misinformer And Scientists’ – ‘Marc Morano is not a scientist and has no scientific education…[he] has compared climate science to the Mayan calendar, Nostradamus, and medieval witchcraft. Moreover, his argument is laughable: by focusing on how carbon dioxide stimulates plant growth in a controlled environment, he ignores that our huge emissions of it and other greenhouse gases are warming up the planet, thereby increasing the risk of extreme rainfall and drought to the detriment of agriculture…So why is Bloomberg News not only featuring Morano, but giving his discredited argument equal weight to the extensive evidence presented by scientists?’
CO2 increases of 80ppm to 100ppm are normal: ‘While CO2 has increased by 85 ppm from when measurements began in 1958 and are estimated to have risen by 120 ppm since 1750, we should also realize that increases of 80 ppm to 100 pm occurred during the last 3 glaciations without humans burning fossil fuels. ‘Air trapped in bubbles in polar ice cores constitutes an archive for the reconstruction of the global carbon cycle and the relation between greenhouse gases and climate in the past. High-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased by 80 to 100 parts per million by volume 600 ± 400 years after the warming of the last three deglaciations. Despite strongly decreasing temperatures, high carbon dioxide concentrations can be sustained for thousands of years during glaciations; the size of this phase lag is probably connected to the duration of the preceding warm period, which controls the change in land ice coverage and the buildup of the terrestrial biosphere.’

Amid 400 ppm CO2 panic, AZStar Net reports: And to see what the future is, scientists look to the past. The last time the worldwide carbon level probably hit 400 ppm was about 2 million years ago’
