Check out this interesting read .
I reads just like a lot of the stuff you see today, only backwards.
The problem is, that's an article in Time magazine. Time magazine has never been regarded as a science journal, it's a news magazine. As sources for the story, they quote a couple of university profs no one has ever heard of.
Now, you can read reports about global warming from the vast majority of climate scientists, published in peer reviewed science journals.
First off, it takes sunlight to make ozone - thats why you have more of it over the equator than you do over the poles in the first place (they sort of conveniently forget to tell you that). So when you put up a satellite and start measuing ppm of ozone in the upper atmosphere, and then plot it in a nice color graph over a picture of the earth, you find there is more ozone over the equator than over the poles (SHOCK! HORROR! OMFG we're all gonna DIE of radiation exposure!).
The monkeys on this planet just don't have a clue...
Or it could be that the scientists studying the ozone layers over the poles actually know that, and weren't expecting to find as much ozone as at the equator. What's alarmed them is that ozone in the upper atmosphere has been declining quite sharply since the 60s. Here, for example, is the National Oceanic & Atmospheric Administration's graph of ozone levels over the Antarctic:

If you go to the website, they've got graphs of historical data for a lot of measuring sites around the world, almost all show a similar trend (although the Antarctic is more pronounced than most.)
yep... high co2 levels follow global warming they don't cause it or even preceed it.
That's one of the things that worries the scientists. Higher temperatures have increased Co2 levels in the past, which is a positive feedback loop.
The
effect of atmospheric CO2 in trapping heat is well known, of course. The past examples of warming did not have man taking the vast amounts of carbon that had been sequestered out of the atmosphere hundreds of millions of years ago, burning it, and adding it back to the atmosphere over a tiny period of time.
As a side note, what has happened to America? When I was a child, America was synonymous with science. Americans went to the moon, sent probes to Saturn, pushed the boundaries in physics and chemistry and biology. When you thought of progress and scientific advances you thought of America.
Now America seems to be turning it's back on science, arguing that evolution is "just a theory", restricting stem cell research, ignoring any science that has unwelcome conclusions.
