CO2 Fairytales in Global Warming

"Of course we know now that CO2 was rolled out as the "poster child" nemesis against the environment. It was meant to get us hysterical enough to plead with our politicians to exact a tax on our carbon footprints so that we can save the planet earth. But it's turning out that the CO2 "poster child" has significant problems. Despite the fact that Carbon is a part of the CO2 molecule, the atmospheric science of CO2 directly contradicts what the AGW alarmists are trying to sell us. Promoting CO2 as the environmental monkey on our back is absolutely ludicrous. CO2 is friend to all life, not a foe."

"current CO2 levels hover around 385 parts per million (ppm), a relatively minor constituent of earth's entire atmosphere -- less than 4/100ths of 1% of all gases present.

Nevertheless, Anthropogenic (man-made) Global Warming (AGW) proponents demand that unless we immediately reduce the amount of CO2 in the earth's atmosphere to less than 350 ppm, we (that is mankind) will cause huge and irreversible damage to the earth.

Historically, and at one significant point indeed, CO2 atmospheric concentrations were much, much higher, 6,000 plus ppm. And guess what? The earth was more than just fine. It was incredibly filled with life.""

"The chart is fairly easy to understand. Note the Black Line on the chart representing "Atmospheric CO2." See how it has been declining for the past 500 million years? Also note that in the Cambrian Age, some 570 million years ago, all of life -- "all" meaning all 34 current animal phyla -- appeared to suddenly explode upon the earth's surface (left-hand side of the chart). Atmospheric CO2 concentrations at that time were estimated to be close to 7,000 ppm. That's a CO2 concentration of 7000 ppm then, 385 ppm now."

"At the time on earth when life seems to have blossomed beyond anything that we've seen, CO2 concentrations were the highest that have ever been recorded. In other words, high concentrations of CO2 didn't seem to have the least ill effect on the greatest expansion of life in the history of the earth.

In fact, it could be argued that the abundance of life arose precisely because high atmospheric CO2 concentrations were soaring; certainly not because of its absence. To be sure, high atmospheric CO2 concentrations and warm temperatures acted to usher in all life on earth. Compared to former geologic times, earth's current atmosphere is unequivocally and fundamentally CO2- impoverished.

So if, as we are led to believe by the AGW crowd, CO2 is a pollutant that will harm all life when its concentrations exceed 350 ppm, how "on earth" did life suddenly explode upon the planet when atmospheric CO2 concentrations were almost 7,000 ppm?"
