• Resumen

  • Kintisch narrates their trip to the eastern Siberian town of Cherskiy, 220 kilometers north of the Arctic circle. Several US scientists from various labs, led by the Woods Hole Research Center in Falmouth MA, have traveled 7,000 kilometers and 15 time zones to Cherskiy to study a phenomenon that might hasten the release of carbon: the rise of Arctic wildfires. The trees at Hellhole--the moniker sticks--were burned a decade ago and could provide an important clue in the debate over the impact of Arctic fire. There is no question that warmer temperatures, drier conditions and, possibly, an uptick in lightning are catalyzing a rise in blazes across the Arctic. This summer over 9 million hectares of forest in Alaska and Canada have burnt--a record--drawing thousands of firefighters to help.
