That's not enough time. My current assumption is that all the worst predicted effects of global warming are going to happen: mass migration, food and water shortages, general political unrest, increasing economic inequality and instability, dwindling energy resources, escalation of national and tribal conflicts, etc. All the signs are there and the question is now whether governments will manage to adapt fast enough to mitigate the worst effects.
