Apparently you attended a "Public" school. When you can demonstrate that we can control the eruption of just one "medium size" volcano, which, by the way, pours more pollutants into the air in minutes than all of mankind has since we began walking upright, then, and only then, will I believe in, or contribute to, or support anyone, or anything, that claims man can effect global warming in any manner whatsoever. I hope the words weren't to big for your "degree". You might want to check with the scientists at the National Laboratories, whom I worked with for many years, and which is managed bu the Department of Energy, about REAL atmospheric pollution, and its sources. Ignorance is more hazardous to your health!
