The Arctic is heating faster than the rest of the planet. Across northern Russia—a region that is famously bitterly cold—temperatures this week have routinely surpassed 90 degrees Fahrenheit (32.2 degrees Celsius), adding to the mountain of broken heat records this summer has racked up so far. In recent days, the Selagoncy meteorological station, near the border of the Arctic Circle, recorded 93.0 degrees F (33.9 degrees C); another station, Olenek, logged 90.9 degrees F (32.7 degrees C), according to data collected by weather information service Ogimet and reported by climatologist Maximiliano Herrera. It’s a dangerous feedback loop: as sea ice melts, the Arctic reflects less sunlight, and the ocean absorbs more heat. In the U.S. in recent weeks, New York City’s Central Park reached 100 degrees F (37.8 degrees C) for the first time since 2012, parts of Montana soared to 111 degrees F (43.9 degrees C), and areas in Idaho, Utah and Wyoming surpassed 100 degrees F (37.8 degrees C).
