The Arctic is on fire. Record-breaking temperatures and strong winds are fueling an unprecedented number of wildfires across the region this summer. In Siberia alone, hundreds of wildfires captured by satellite images July 28 spanned about 3 million hectares of land. Across Alaska, as many as 400 wildfires were burning as of mid-July. And the heat is also melting Greenland’s ice at an alarming rate.
