Professional Book Photographer Of the YearThe Arctic: A Darker Shade of White chronicles deep, immersive expeditions in the high north. I was fortunate to walk to the North Pole on skis; I crossed the Greenland ice sheet in its length; and covered great distances across the Canadian Arctic. Throughout 20 years of challenging polar missions, I never ceased to be moved by the power and scale of the landscape. This communion I had with Nature always led to epiphanies even while that harsh environment takes no pity on human life. But from year to year, I bore witness to transformations that spell profound global implications.
