So I was looking at CNN.com and came across this article :

(CNN) -- The ozone hole over Antarctica in 2008 is larger in both size and ozone loss than last year, but not as large as in 2006, the European Space Agency said Tuesday.


Some chemical processes produce ozone-depleting gases.

The hole is a thinning area in the ozone layer over Antarctica and the size of the hole varies every year depending on weather conditions.

This year, the size of the thinned area reached about 27 million square kilometers (10.4 million square miles), compared to 25 million square kilometers (9.65 million square miles) in 2007.

In 2006, the hole was a record 29 million square kilometers (11.2 million square miles), larger than North America, the ESA said.

The ESA announced its results based on information from German and Dutch researchers who analyzed satellite data.

Depletion of ozone is caused by extreme cold temperatures at high altitude and the presence of ozone-destroying gases, such as chlorine and bromine, in the atmosphere, the ESA said.

Those gases originate from man-made products like chlorofluorocarbons, or CFCs, which were phased out under a global agreement two decades ago but continue to linger in the atmosphere.

Ozone is a protective atmospheric layer found at an altitude of about 25 kilometers (15.5 miles).

It acts as a sunlight filter, shielding life on Earth from harmful ultraviolet rays that put humans at greater risk of skin cancer and cataracts and harm marine life, the agency said


...... and something jumped out at me. In the article, it was stated that a cause of ozone depletion was extreme cold temperatures at high altitude. Now, I'm not a smart person by any stretch of the imagination, so maybe one of you smart guys can educate me on something; if extreme cold temperatures is one of the causes of ozone depletion, then would it stand to reason the global warming could be a good thing? I'm not looking for arguements about global warming and who's to blame or if it's even real, I just wonder if my limited intelligence is missing something here.

what they are saying is that ozone depleting gasses only actually break down the ozone at the cold temperatures at high altitude. global warming probably isn't going to warm the air that is in the stratosphere near outer space where it is hundreds below zero. but anything is possible, though I doubt it.

And even were it changing anything significant at that kind of altitude, the negatives of global climate change significantly outwiegh any minor benefit associated with the hole in the ozone.

oh, yeah, that isn't even a question.

While I'm not a huge fan of NASA, they have their place. What we know about global warming we know from studying Venus by NASA

Warming is a symptom, not a cause here.

Don't think about ozone depletion and global warming. Think about ozone depletion and the greenhouse effect. Then think about greenhouse effect and global warming if that's the terms that frame the discussion.

You lost me there champ.

Without questioning whether or not we are the cause, we can look at Venus and see how a lack of an ozone layer allows UV light through to absorb water. We can see how CO2 and CO and Sufuric Acid rise in a perpetual way. We can see how heat is trapped, increasing water depletion increasing water evaporation that feeds the creation of C02 and CO and Sulfuric Acid.

Understanding Venus is the key to understanding how important the Ozone layer is. At the same time we don't really know how to maintain that layer (as far as I know), we can just see how important it is for maintenance of the Earth as we know it.

I'm still not following you. Ozone is created by natural processes and then rises up to the stratosphere and forms a narrow band that filters some kinds of radiation. We are now manufacturing many ozone depleting substances that rise up there and break it down. That allows in kinds of radiation that have minimal effect on global temperatures, but are damaging to cells and life. That has little to do with water or heat trapping or global warming as far as i know.

Venus' atmosphere is nothing like ours. Just for starters, there is no life there. When CO2 increases on earth, plants and algae grow faster and sequester it. Water vapor (of which there is none on Venus) increases changing the transmission rates of heat and light. Etc etc.

I'm not trying to give you a hard time. I'm just really not following you.

Global warming is bad. Extremely bad. Al gore told me.

Really I thought he said we needed to pour some Robitussin on it to cure the fever?????
