Carbon Dioxide above 400 ppm — A typical AP Climate story

Five days ago, the Associated Press ran a story,  Carbon dioxide at highest level in 800,000 years.  It is typical of AP climate stories, unfortunately.  There is some interesting information in the article, but the article serves up lots of misinformation too.  The second paragraph of the article states that:

Years ago, it passed the 350 ppm mark that many scientists say is the highest safe level for carbon dioxide. It now stands globally at 395.

The highest safe level, give me a break.  That is wild speculation and an extremist view.   Most global warming hawks would be happy if we could get carbon dioxide to stop rising before it reaches 450.  And many scientists think all this carbon dioxide boogie man stuff is crap too.  We live in an Ice Age cycle, a little warming is probably a good thing.

My favorite paragraph:

Carbon dioxide is the chief greenhouse gas and stays in the atmosphere for 100 years. Some carbon dioxide is natural, mainly from decomposing dead plants and animals. Before the Industrial Age, levels were around 275 parts per million

Carbon dioxide is not the chief greenhouse gas, water vapor is.  Most, not some carbon dioxide is naturally produced and forest fires and volcanoes are significant natural pieces left out.  Man produces about 3% of the total.

Yes, carbon dioxide warms the atmosphere more than it otherwise would, but the amount that is optimal is always a SWAG and it’s impact on climate is  theory….not a fact….and there is scientific disagreement on this subject…but not at the AP.
