As oil production has grown in North Dakota, so has the amount of natural gas flared into the atmosphere. The soaring flames, visible from space, “illuminate the prairie skies like giant fireflies.” More insidiously, North Dakota’s gas fires produce at least two million tons of greenhouse gases each year, as much as a coal-fired power plant or 380,000 cars.
