The Flip Side Of The Polar Vortex

Or, How The Right-Wing Forgets Alaska Exists

Melting Ice In Alaska Has Lead To Coastal Erosion

Right-wing media are laughing about President Barack Obama mentioning climate change in his fifth State of the Union address because it is cold in D.C. But the wobbly polar vortex bringing cold air to much of the contiguous United States is simultaneously causing record warmth in Alaska, a state often seen as the nation's "ground zero" for climate change.

On January 28, Alaska's largest newspaper, the Anchorage Daily News, ran this remarkable headline: “Record warmth, confused plants: An Alaska January to remember.” The article noted that it was 62 degrees Fahrenheit in one town, tying the January state record, but did not allude to the long-term warming trend. In November, the newspaper did briefly invoke the possibility of climate change while expressing disbelief that strawberries were growing “In Anchorage. In November.”

Yet just a year ago, right-wing media claimed the state was headed toward “an ice age.” The Alaska Dispatch, a prominent online news site, ran the misleading headline, “Forget global warming, Alaska is headed for an ice age.” The report was promoted by the conservative British tabloid, the Daily Mail, and the climate denial site, WattsUpWithThat, which highlighted the state's relatively lower average temperature in 2012.

Alaska Temperatures Rising In Long-Term

As the chart above also shows though, cherry-picking a short-time period is misleading -- natural variation can mask the long-term trend. Contrary to claims of an “ice age,” studies project that average annual temperatures in Alaska will increase “an additional 3.5 to 7°F by the middle of this century,” according to the Environmental Protection Agency (EPA).

Warming in Alaska already has caused highways to buckle and homes in areas such as Shismaref, pictured above, to sink, as the EPA explained:

Many of Alaska's highways are built on permafrost. When permafrost thaws, roads buckle. Vehicles are only allowed to drive across certain roads in the tundra when the ground is frozen solid. In the past 30 years, the number of days when travel is allowed on the tundra has decreased from 200 days to 100 days per year.

Along Alaska's northwestern coast, increased coastal erosion is causing some shorelines to retreat at rates averaging tens of feet per year. Here, melting sea ice has reduced natural coastal protection. In Shishmaref, Kivalina, and other Alaska Native Villages, erosion has caused homes to collapse into the sea. Severe erosion has forced some Alaska Native Villages' populations to relocate in order to protect lives and property.
