Global Warming and Continuous Change

As senior energy analyst Glenn Doty points out, perhaps the most problematic aspect of climate change is that the nastiest effects, e.g., sea-level rise, will change continuously for centuries.
Thus we have questions like: Where should we rebuild New York City when Manhattan Island goes under water? There really is no good answer to that question, unless you want to put it next to Denver at 5000 feet above what is now sea level.
