The stark differences over timescales of only 50 or 100 years is sobering. I cannot understand politicians and scientists who persist in denying the implications of global warming, even if there are reasons for doubting the specifics of the human contribution. Coupled with the potential impact of global dimming, things are going to get a lot worse. There's no room for business as usual.
