The oft-cited statistic is "97% of climate scientists believe in anthropogenic climate change" and the wikipedia article [1] is actually quite thorough. I personally do not know any scientist who doesn't believe in global warming, although I did know some skeptics a decade ago. Skepticism is healthy, but so is respecting statistical tests.

No one really knows the specifics of what's going to happen, but the latest IPCC (Intergovernmental Panel on Climate Change) has started focusing on 'adaptation' as some degree of climate change is inevitable (and, indeed, has already happened). The IPCC would be my choice as the closest guess as to what the next century will look like [2]
