Sunday’s slide in Southeast Alaska occurred at 5:24 a.m. local time and flowed in the east-northeast direction, according to a Columbia University geologist. A rough estimate suggests it sent about 68 million metric tons of debris down a mountain slope.Yereth Rosen
Six decades of development on and around Alaska's oil patch, combined with the effects of a warming climate, have dramatically changed the landscape in the state's far north, a new study says.Yereth Rosen
Bering Sea ice cover was “pronounced” in four of the last 33 years, including 1992, 1999 and 2009. Ice was thickest in 2012, covering an average of 109,000 square miles, an area slightly larger than Colorado.
Barrow, the state’s icebox with an average annual temperature of 12, warmed 2.6 degrees above normal. That’s in line with decades of warming on the North Slope and the ”strong decrease” in sea ice in the Arctic Ocean north of Alaska.
Disease may have spread because melting sea ice removed a key barrier that previously kept northern and southern animals apart. Now, as waters warm and southern animals chase the fish that are moving north, the animals are mingling.Yereth Rosen
The itty-bitty sand lance could be the culprit behind drops in the populations of Western Alaska's Steller sea lions, sea otters and northern fur seals, and maybe even offer another clue to recent baffling king salmon declines.
Alaska has enjoyed a streak of good luck in the 50 years since the Good Friday Earthquake. But inevitably a big one will strike again, and there are some lessons we can learn before that happens.Ned Rozell
