What would it be like to have an Ozone hole above the north pole?

[Silverspeed]

We all know that there is a hole the size of America in the southern hemisphere, But what would happen if it had a simalar effect in the northern hempshere?

 

Leave a reply with your answer.

you could get a tan(but no heat) up at the pole.

 

also, something freaky would have to happen to atmospheric physics for that to occur.

I'm a big supporter of this ozone hole and what it wants to accomplish.

I was under the impression that we already have a ozone hole in Arctica, albeit much weaker.

 

Reductions of up to 70% in the ozone column observed in the austral (southern hemispheric) spring over Antarctica and first reported in 1985 (Farman et al 1985) are continuing. Through the 1990s, total column ozone in September and October have continued to be 40–50% lower than pre-ozone-hole values. In the Arctic the amount lost is more variable year-to-year than in the Antarctic. The greatest declines, up to 30%, are in the winter and spring, when the stratosphere is colder.

 

Reactions that take place on polar stratospheric clouds (PSCs) play an important role in enhancing ozone depletion. PSCs form more readily in the extreme cold of Antarctic stratosphere. This is why ozone holes first formed, and are deeper, over Antarctica. Early models failed to take PSCs into account and predicted a gradual global depletion, which is why the sudden Antarctic ozone hole was such a surprise to many scientists.

 

In middle latitudes it is preferable to speak of ozone depletion rather than holes. Declines are about 3% below pre-1980 values for 35–60°N and about 6% for 35–60°S. In the tropics, there are no significant trends.

And the "tan" is supposed to be dangerous, in Scandinavia we are warned not to expose our skin to the Sun during summer, from time to time depending of where the depleted area is present.

Since the ozone layer absorbs UVB ultraviolet light from the Sun, ozone layer depletion is expected to increase surface UVB levels, which could lead to damage, including increases in skin cancer.
