I foolishly decided a few years ago to look with my own eyes.

I went on an expedition to the shore of the Arctic Ocean (admittedly, in my diesel-fueled Hummer H1).

I made it to Tuktoyaktuk:



There I found considerable evidence of a qualitative change in permafrost characteristics in the region, and erosion of native sites that had been there for thousands of years, caused by increased storm strength and open ocean fetch.

Clearly there is *something* going on, and I believe it is reasonable to be prudent.

Now, here where I live, I have hairshirt greenies demanding we restrict building within 20 feet elevations of high high tide, because of "sea level rise predictions". I think they are not so interested in preservation, as prevention of human activity within the shoreline region.
