http://www.youtube.com/watch?v=TUiP6dqPynE What do you know about it? I just watched a documentary on it recently, very interesting. Brief definition: A type of pollution that has caused us to underestimate global warming by reducing heat through sunlight reflective clouds which are a product of our pollution. Obviously, a vast underestimation of global warming is a bad thing. The documentary had some unpleasant possibilities to offer: destruction of the rain forests, massive soil erosion, release of methane from the bottom of the ocean (ten times worse than the release of all our greenhouse gases, or some such). The documentary predicted that we had ten years to drastically curb our greenhouse emissions before reaching the point of no return. That point being the point where it is too late to solve the problem, not the date of feeling the brunt of it's predicted effects. So if this is true, we're screwed, because imo we won't stop no matter what. I have yet to see it refuted. I think it is just starting to catch on though. It will surely be in Al Gore's soon to be released documentary "An Inconvenient Truth", designed to be a frightening movie on the state of the environment (May 24). what do you think?
