Comments on: Ozone hole living longer than expected

Keep that sunscreen handy. The hole in the ozone layer will last 15 years longer than expected, scientists say.

Ozone hole is a natural occurance

CFC levels will never drop low enough to close the hole. Volcanoes put out great amounts of CFC's. Pinatubo for example, put out, in one eruption, 50x the amount of man made CFC's ever made.

There's also the fact that the ozone is created by ultraviolet light. When the poles are dark, they get very little UV exposure, and much less O3 is created.

CFC's are also heavier than air. So when they leak out, they tend to pool in low lying places. Thats one of the safety concerns when working with coolents. You can be asphyxiated if not careful. Even out doors with a slight breeze, if the ground is depressed even slightly, it will pool.

Here are some facts...

Here are some facts concerning volcanoes and other natural sources:

Volcanoes causing this problem is a myth. Manufactured chemicals causing this problem is an established fact at this point. There have been various studies to prove this.

Invalid argument

First page when googling for cfc weigt:

Your weight argument makes no sense. Fortunately on this matter your ignorant opinion was not followed.

All natural occurances of CFC's are what they are, part of nature. This means it is part of earths ecosystem, so it part the balanced system. Everything we add to it, disrupts the balance.

Don't forget we are dealing with chaotic systems here, small modifications can have big consequences. Ever heard of the quote: "If a butterfly claps its wings in London, a thunderstorm in Moscow is the result of it?"

don't..

try to reason with environmentalists. In the ecofreak world, nature is perfect and any "imperfection" (as defined by ecomania, not by reality) must be caused by man.

There is no reasoning with these people - it's a religion to them, and no amount of science or reason will convince them. It's as bad as trying to discuss evolution with a fundie.

weather

They write about ozone and globel worming but right not it is 5 deg. cold which is colder at this time then it's been for a number of years.

Emm, its about average

Global warming is about the increase in average temperature, not at a specific point of time. We are going to have much more extreme weather compared to the recent past, and colder weather is part of global warming, though it sound paradoxical.
