Arctic Warming
Global warming is most apparent at high
northern latitudes, that is, in the Arctic.
Temperatures in Alaska has already risen 3
to 5 o F, twice as much as in the main 48 states
Anticipated thawing of as much as 90 percent
of the permafrost will result in the
displacement of pavements, runways, rail
lines, pipelines, buildings, and bridges
