The air from the Northern and Southern hemispheres doesn't mix. The big hole is over Antarctica in the Southern hemisphere. Most pollution is produced in the Northern hemisphere. Please explain????

the situation you state refers to the ozone hole and not to global warming, they are different situations.
With the short space I have, in the south there is less pollution but less upper air circulation so chemicals gather in one place, and more extreme sunlight.
Chemicals gather throughout the year in icy polar stratospheric clouds, when the sun hits them all the chemical reactions happen at once.
In the north the solar radiation does not undergo such extremes, and the pollution can spread evenly throughout asia and europe, and even to the equator and south
global warming is about the carbon dioxide and other pollutants retaining heat in the atmosphere, not destruction of the ozone layer, which is a different phenomenon

The air does mix. Slowly, but Northern Hemisphere pollution still gets South.

Fact- the Earth has seen a slight increase in temperature over the last few decades and is, either in part or in whole, caused by man.
Fiction- this trend is solely natural. Yes increases and decreases have happened on earth before, but without cataclysmic events they do not proceed with nearly the same haste as this current one.
Fact- Scientists know humans are playing a role, but have no idea how large or small that role may be.

I don't think Global Warming is due to pollution from us. I mean if you think about it, we have supposedly only been on this Earth for a fraction of the time it's existed. If there was an "Ice Age" wouldn't it make since that there would be a Global Warming afterward? If you're really cold, the only way for you to go is up, right?
p.s. people should still clean up after themselves and not be selfish pigs though...I'm in no way saying that we should stop caring for our planet.

global warming is a fact.
most pollution is in northen hemisphere due to fact that most of habitable land is in northen hemisphere.

Fact, and we are responsible for about 2/3 of it, maybe as much as 3/4
By the way, once again, the hole over the antartic HAS NOTHING TO DO WITH GLOBAL WARMING

You are wrong, global climate change is natural which has been increased by human activirties. If you take geological time scale you could found, how many ice aes and warm ages existed in the world. the world ocean water current and surface current does not shows long term changes. It shows the climate change is progress not by human activities. I suspect that is the reason USA has not ratified Kyoto protocol.

Global warming - fact.
Al Gore - fiction.
That we're responsible for it - fiction. If we are how did global warming happen before cars, factories, etc.? How did we get from the Ice Age to where we are now?
