Welcome to Berlin, Algeria

From The Guardian comes a colorful and disturbing map purporting to show where some of the great cities of Europe will be, climate-wise, in 2071. Paris, for instance, will have a climate that today would be somewhere south of Madrid. London heads to Portugal. And so on. Perhaps most dramatic are the Scandinavian cities of Stockholm and Oslo, which find themselves somewhere on the Iberian peninsula. I won't be around to see it -- but some of you might.

Anyone seen something similar for the US? How much worse can New York City get in the summer?
