Alaska Communications is planning to repair or replace about 20 telephone poles that are slowly falling over along a swampy stretch of the Richardson Highway north of Delta Junction.  It’s a recurring problem that Alaska telecoms have dealt with for years. And there’s concern that climate change is likely to make it worse in the years ahead.

Dozens of national experts on ocean policy, research and business gathered at the University of Alaska Fairbanks this week to talk about how climate change is affecting the Arctic Ocean and coastal communities. Members of the Joint Ocean Commission Initiative’s held an Arctic Ocean Leadership Roundtable at UAF to learn about its ongoing Arctic-research resources, and then traveled north to talk with Inuit people to get their perspective on changes they've seen in the region.


Fairbanks, AK  - Scientists have long believed melting permafrost emits large amounts of carbon-rich greenhouse gases like methane and carbon dioxide to the atmosphere resulting in a warming climate.  But a new study published online by the journal Nature indicates ancient lakes that formed after permafrost fin the Arctic first melted roughly ten thousand years ago may in fact have a net climate cooling effect over long time scales.  The the study also increases the total amount of carbon estimated in the frozen soils of the Far North by more than 50 percent.
