Those Alaskans must have a lot of free time on their hands.
I thought maybe frozen gore was what was left behind after Palin field dressed her moose.
I wonder if Al Gore would still be preaching global warming if he had frost on his testicles - that is, if he has any?
Gore is too effeminate to have testicles.
Frozen Gore - that is pretty awesome!
haha, that's funny.
Interesting that Gore won't go see the people in Alaska, or anyone else who calls him out on his bullshit.
Really fucking dumb comments from some fucking dumb assholes. Are you guys ever going to grow up and actually research something before talking out of your assholes?
Alaska’s climate has warmed about 4°F since the 1950’s and 7°F in the interior during winter. The state experienced a 30% average increase in precipitation between 1968 and 1990. The growing season has lengthened by two weeks. Sea ice has retreated by 14% since 1978 and thinned by 60% since the 1960s with widespread effects on marine ecosystems, coastal climate, and human settlements. Permafrost melting has caused erosion, landslides and damaged infrastructure in central and southern Alaska. Recent warming has been accompanied by “unprecedented increases in forest disturbances, including insect attacks. A sustained infestation of spruce bark beetles, which in the past have been limited by cold, has caused widespread tree deaths over 2.3 million acres on the Kenai Peninsula since 1992, the largest loss to insects ever recorded in North America” (US Global Change Research Program, National Assessment, 2001).
Scientists expect Alaska’s climate to get warmer in the coming years—and the changing climate could make it roughly 10% to 20% more expensive to build and maintain public infrastructure in Alaska between now and 2030 and 10% more expensive between now and 2080.
These are the first estimates of how much climate change might add to future costs for public infrastructure in Alaska, and they are preliminary.
“Public infrastructure” means all the federal, state, and local infrastructure that keeps Alaska functioning: roads, bridges, airports, harbors, schools, military bases, post offices, fire stations, sanitation systems, the power grid, and more. Privately owned infrastructure will also be affected by climate change, but this analysis looks only at public infrastructure.
A warming climate will damage Alaska’s infrastructure because it was designed for a cold climate. The damage will be concentrated in places where permafrost thaws, flooding increases, and coastal erosion gets worse. But the extra costs will likely diminish over time, as government agencies increasingly adapt infrastructure to changing conditions.
Keep in mind that we’re not projecting how much Alaska’s climate may change in the future. Scientists from around the world are doing that. We’re estimating how much the future costs for public infrastructure in Alaska might increase, based on what scientists expect to happen.

Observed Climate Trends
Alaska has warmed substantially over the 20th century, particularly over the past few decades. Average warming since the 1950s has been 4�F (2�C). The largest warming, about 7�F (4�C), has occurred in the interior in winter. The growing season has lengthened by more than 14 days since the 1950s. Some records suggest that much of the recent warming occurred suddenly around 1977. Alaska has also grown wetter recently, with precipitation over most of the state increasing 30% between 1968 and 1990. The observed warming is part of a larger trend through most of the Arctic corroborated by many independent measurements of sea ice, glaciers, permafrost, vegetation, and snow cover. In contrast to other regions, the most severe environmental stresses in Alaska at present are climate-related.
December of 2009, the interior of Alaska was 6 to 8 degrees warmer than normal for December.
