Although I feel sorry for the residents of Kivalina, it really is a poor place for a town. Years ago the people would have just picked up and moved. Permanent towns have no business being located in places such as where Kivalina is.
Regardless of climate change, spits such as the one Kivalina is built on have been coming and going for millennia. Nature will eventually win. We can spend millions of dollars in the meantime fighting the inevitable; but why?
