It may just be a matter of delaying. this topic needs serious scientific inquiry, yet do we have time? no one really knows, but no one can really risk it either. If Global warming doesn't result in anything more than global warming, then plants and animals will die, we will lose our coasts and much much more. A study I read for Environment Canada cliamed parts in Canada will reach 38 degrees celcius on a normal day by 2050. Either way, greenhouse gases have to go.
