I saw him speak here in Portland last year.

I don't have the numbers right, but basically there used to 300and some days of Permafrost in ANWR. Last year there were 70something.

I'll try to find it...

68. Interior Alaska -- Permafrost thawing. Permafrost thawing is causing the ground to subside 16-33 feet (4.9-10 m) in parts of interior Alaska. The permafrost surface has warmed by about 3.5?F (1.9?C) since the 1960's.

Permafrost underlies most of Alaska, and the recent several decades of warming have been accompanied by extensive thawing, causing increased erosion, landslides, sinking of the ground surface, and disruption and damage to forests, buildings, and infrastructure. Thawing is projected to accelerate under future warming, with as much as the top 30 to 35 feet (10 meters) of discontinuous permafrost thawing by 2100. Warming is also likely to impair transport by shortening the seasonal use of ice roads.
