The increasing scrutiny of ExxonMobil comes as record-high temperatures in Alaska have forced organizers of the Iditarod to transport a train-full of snow to Anchorage because there is not enough snow for the famous dog sled race. Organizers also say the teams will cover only three miles on Saturday’s ceremonial start—rather than the usual 11 miles—because of the lack of snow on which to sled. This is the second year that the lack of snow has forced organizers to make changes to the race.
