Part III -- Conclusion
At this point one should ask what the Marshall Islands in the Pacific have in common with lower tip of Manhattan on the Atlantic coast of the United States. The answer is that both are threatened with inundation by 2100. In the case of lower Manhattan, it might be possible to build a sea wall to temporarily hold back the rising sea level. No such effort is possible for the Marshall Islands. It looks as if that island nation, with its roughly 53,000 people, is doomed.
The prospect that 195 nations can successfully coordinate their efforts to put in place policies that, over the next hundred years, will negatively impact their economies and the standard of living of significant numbers of citizens is far-fetched. Not impossible, mind you, but from a historical point of view, highly improbable.
What is probable is that local interests will promote denial long enough to make the necessary sacrifices politically unachievable. They certainly have done so so far. That means our grandchildren will almost certainly live in a very different atmospheric and geographic world than we do. And, of course, going forward, no one should invest in seashore real estate.
