Right now, I’m writing from a small ship’s cabin in one of the most isolated, desolate places on earth: the northern tip of Svalbard in the high Arctic, where I have come on an expedition, part of the point of which was to see what I’ve just seen. Which was a shelf of translucent blue ice the height of a house falling into the water like wet cake.
