Global warming chickens coming home to roost

As made clear by a NYT article on the plight of the Marshall Islands in the Pacific Ocean due to rising sea levels, climate change will be costly to the US beyond the amelioration of its effects on the homeland.  Due to treaty obligations to the Marshallese, we will probably have to resettle the entire population in the US if the seas continue to rise.   This may be the tip of the proverbial iceberg of refugees demanding haven.  Meanwhile, the GOP is renouncing in advance any obligations the country may incur at the Paris Climate Summit.   It is increasingly ironic that aside from an occasional weather event like Superstorm Sandy or the ongoing drought in  California, most of the US has not experienced wholesale destruction due to climate change.  For the rest of the world, especially many countries in the Third World, the rising seas, catastrophic drought and super typhoons which regularly ravage their citizens, the changing climate is an ever present reminder their troubles are largely caused by the superpowers of polluters, the US, China, Europe and developing countries like India and Brazil.   Of the aforementioned, most are trying to do something about the problem.   In America, however, denial of climate change is more common than plans to do anything about it.   If Paris is the last, best hope for the human race, I despair of our congressional leadership doing anything substantive.
