We've got a climatological tipping point in roughly 10 years. We're too short-sighted to do anything significant in that span. In 50 to 100 years climate change will have caused major disasters, draughts and famine across the globe, leading to uncontrolled rioting and small-scale wars that soon blossom into a global war. No one really knows who launched the first nuclear weapon, but once airborne, itchy fingers in Russia, the U.S, China and the Middle East join the fray. The Earth is left a smoking ruin, and then nuclear winter sets in, immediately reversing the global warming trend. Unfortunately, we aren't around to enjoy our new winter wonderland.
