Well, why don't you read them and find out? Alternatively you could accept this: Geophysicists Urge Steep Cuts in Greenhouse Gas Emissions The American Geophysical Union says massive reductions in greenhouse gases will be needed—and scientists should speak up about it http://www.sciam.com/article.cfm?id=geophysicists-urge-steep-cuts-in-greenhouse-gases They want a cut by 50% by 2050. With practically all our energy coming from fossil fuels, then that seems to be to be impossible unless we cut our consumption by 50%. Obviously, in the underdeveloped regions of the earth where most of the global population live at subsistance level, that is not possible. Hence we in the developed regions will have to cut our consumption by even more than 50%. Of course, it may be true, as Wilkins Micawber used to assert, that "something will turn up." http://en.wikipedia.org/wiki/Wilkins_Micawber But all that his optimism did for him was to land him in jail. It seems inevitable that if we too persist in our optimism, we too will end up in an unforeseen catastrophe!
