What the fate of Greenland means for the rest of the Earth. By Elizabeth Kolbert
In the middle of the night in the middle of the summer in the middle of the Greenland ice sheet, I woke to find myself with a blinding headache. An anxious person living in anxious times, I’ve had plenty of headaches, but this one felt different, as if someone had taken a mallet to my sinuses. I’d flown up to the ice the previous afternoon, to a research station owned and operated by the National Science Foundation. The station, called Summit, sits ten thousand five hundred and thirty feet above sea level. The first person I’d met upon arriving was the resident doctor, who warned me and a few other newcomers to expect to experience altitude sickness. In most cases, he said, this would produce only passing, hangover-like symptoms; on occasion, though, it could result in brain swelling and death. Belatedly, I realized that I’d neglected to ask how to tell the difference. |
