An utterly, completely bullshit theory, revolving around CO2, chloroflourocarbons, and other, man-generated pollutants causing the O3 layer to decay, and insulate the atmosphere.
Of course, one large volcanic eruption, such as that at Mount Saint Helens, or another, would spew more ash and pollutants - which, according to this theory would cause the earth to become hotter - in reality, releases more pollutants, than humans do at their current rate in 50 - 100 years. Such events generally occur roughly every 10 years, globally.
On to point two, the earth's climate has been changing constantly since its creation. There've been numerous ice ages, and hot periods in the past, all of which were caused by nature, not people. Of course, one may argue that this "climatic change" is accelerated, but how is one to know that?
Simply put, there are far too many variables which result in a global alteration of the climate of earth, with one of the smallest being pollutants. Isolating and neutralizing most pollution will definitely help large, urban centers, such as Los Angeles, New York, Seattle, for instance, which do have smog problems, but will not affect the entire earth.
Global warming is not an established, scientific fact, you douchers. It is a theory; no more, no less. Taking it as cannon, or dogma, as most "scientists" do, is unscientific, beside being preposterous.
