Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

...here. Epstein said that since the early 1960s the spring thaw in Alaska's tundra country is arriving an average of 2.3 days earlier each decade. As a result, plants in the region now "leaf out" about 2.7 days earlier than in previous decades. Likewise, the first freeze each year is arriving slightly later,...
