As atmospheric carbon-dioxide levels verge on 400 parts per million (ppm), climate cluckers are aflutter over what Chicken-Little-in-chief Al Gore has called “A sad milestone. A call to action.” But this alarm is as baseless as any sounded by the blame-mankind crowd.
Countering their politically driven alarmism with cold, hard scientific facts that show why CO2 at 400 ppm is a nonissue is ClimateDepot.com's Marc Morano. He notes that:
• CO2 is just one of hundreds of factors governing temperature and climate.
• From geology's long-view perspective, current CO2 levels are remarkably low.
• Peer-reviewed studies have shown that ice ages occurred when CO2 levels ranged from 2,000 ppm all the way up to 8,000 ppm; that temperatures comparable to today's prevailed even with CO2 levels 20 times higher; and that CO2 rose as high as 425 ppm nearly 13,000 years ago — when humanity couldn't possibly have influenced climate.
• Ice-core data show temperatures rise hundreds or thousands of years before CO2 levels rise.
• And there's considerable evidence that climate drives CO2 levels, not the other way around.
That the Chicken Littles cluck so loudly over 400-ppm CO2 levels despite such damning evidence against their case reveals them for the science-twisting, anti-growth political opportunists they are. Experts at doctoring evidence to fit their preordained conclusions, they're now simply ignoring the inconvenient scientific truth about CO2.

You are solely responsible for your comments and by using TribLive.com you agree to our Terms of Service.
We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.
We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.
