"Twice a week throughout the year, Hannah James walks almost half a mile in Greenland's punishing conditions to reach an area with pristine air. She stops to put on a so-called clean suit, designed to keep the environment as sterile as possible. From there, she hikes another 300 feet to collect a snow sample. Hannah is a science technician for a logistics company called Polar Field Services. In Greenland, scientific researchers are mining the icy environment for data to understand how #climatechange will alter the rest of the globe. The @nytimes photographer @joshhaner spent 7 days 10,530 feet above sea level on the Greenland ice sheet. We'll be sharing more of @joshhaner's photos from #Greenland this #nytweekender."
