He’s had just a few hours of sleep, and he still overslept. Today he and his expedition partner, Ryan Waters, are making their final push to the North Pole, less than four miles away. But the whipping wind is pushing the big ice floe where they set up camp southward, and every moment counts. At this point, the two veteran adventurers have spent 53 days inching across the Arctic sea ice, and today will be another slog through slushy leads and over hummocks. When they began planning this expedition, they expected it to be treacherous. That was the point. They wanted to show the world how climate change was already wreaking havoc on the North Pole—in fact, they’re calling this the Last North Expedition. They predict that their method of reaching the Pole on foot will soon be impossible.
