Arctic Ozone Layer Thinning Due to Record Cold

The ozone layer over the arctic is decreasing due to record COLD temperatures in the arctic (where all the ice is supposed to be melting and causing all this flooding...)

[Klinglerware]

Global warming and the depletion of the ozone layer are two completely different processes. The only linkage is that many of the pollutants thought to contribute to the greenhouse effect contributing to man-made global warming also happen to eat away at the ozone layer.

Thus, global warming can't decrease the ozone layer. They are both effects that are not causally linked to one another.

If only Bush had used diplomacy and economic sanctions on the hole in the ozone layer while we still had the chance.

I would add that in your zeal to bash "The people pushing Global Warming", the fact still remains that the big bad ozone hole is still out there, no matter the origins. It would probably behoove you to ramp up on the sunscreen yourself

Actually, if the article is correct, it could be inferred that Global Warming could HELP the ozone layer as it would prevent the cold temperatures that are causing the "thinning" in the Arctic ozone layer.

The thing that always bugged me is, if it was CFCs that was causing the hole in the ozone layer in the Antarctic, why wasn't a corresponding one formed in the Arctic, since most of the CFC producing and consuming nations were in the Northern Hemisphere?

In any case, I think there is too little known about the processes that affect both global warming and the ozone layers to blame it on man.

I had thought one of the predicted effects of global warming was a loss of gulf stream activity. Used to regulate temperatures in the upper atmosphere, among other things, wouldn't the loss of heat in the Arctic upper atmosphere be predicted. Second most doom saying about ice loss has come from Antarctica not the Arctic. Third ozone hole has always Antarctica issue now it seems to have begun in the Artic too ... oh joy! Finally the article mentions that this is the coldest winter in 50 years, hopefully it is an anomoly.

Taken as a whole this article does much to support a dramatic swing in our global environment .... or it was just really cold this winter. Lets hope for the latter but study the former.

I knew those Tree Huggin' Libs were smokin' something. :D

I don't know enough about the gulfstream to know if this would be predicted. However, I thought the gulfstream warmed England and Europe, not the Arctic?

Not true, they used to talk about the Arctic as well. It's just that there's more ice in the Antarctic, so it melting would have a larger impact on sea level. Also there is one glacier that has been receding, and it's been championed by the Global Warming crowd (ignoring the fact that other parts of the Antarctic ice sheet have been getting thicker).

Third ozone hole has always Antarctica issue now it seems to have begun in the Artic too ... oh joy!
I'm not cheering that we're getting an ozone hole. I'm just pointing out that the Arctic is colder than ever recorded, which seems to fly in the face of all the stories over the last 20 years about how much warmer its getting and how much ice is melting...

Finally the article mentions that this is the coldest winter in 50 years, hopefully it is an anomoly.
If Global Warming is such a dire problem, why would this be a "hopefully"?

I think the article adds to the evidence that we aren't in fact undergoing a dramatic swing in the environment, but just regular peturbations back and forth, with a possible gradual slide toward a new climate that is likely to take thousands of years, like every other climate change on this planet. The planet tends to have a gradually shifting climate, but certainly not the dramatic swings being thrown about in the popular press.

It's the average temperature of the entire Earth that matters, not localized conditions. In fact, as I understand it, global warming theory does predict wider extremes on both ends of the temperature scale locally, so this is not necessarily inconsistent with global warming.

As far as what Whar was mentioning about the Gulf Stream being turned off by cold water from glacial melting, causing colder temperatures in northern Europe that is indeed one hypothetical consequence that has arisen in recent years.

everything i know about global warming i learned in Crichton's "State of Fear".

My guess is that you are better informed than most. However biased the source may be considered.

So now there's a pro-Global Warming group? :rolleyes:

Does this mean that I won't have to worry about a giant superstorm sucking up all the warm air and instantly freezing Dennis Quaid's son?

I think they are based in Canada.
