Merle Savage has a wheezy, guttural smoker's cough. But the 71-year-old former Alaska resident and author of Silence in the Sound never smoked a day in her life. She did, however, spend four months as a general foreman during the Exxon Valdez oil spill recovery project in 1989. And she has a message for anyone working at the BP oil disaster sites: "You've got to use your common sense. Breathing crude oil is toxic."

With the Gulf Coast dying of oil poisoning, there's no space in the press for British Petroleum's latest spill, just this week: over 100,000 gallons, at its Alaska pipeline operation.  A hundred thousand used to be a lot.  Still is.

On Tuesday, Pump Station 9, at Delta Junction on the 800-mile pipeline, busted.  Thousands of barrels began spewing an explosive cocktail of hydrocarbons after "procedures weren't properly implemented" by BP operators, say state inspectors. "Procedures weren't properly implemented" is, it seems, BP's company motto.

Tiny Kivalina, Alaska, does not have a hotel, a restaurant or a movie theater. But it has a very big lawsuit that might affect the way the nation deals with climate change.

Kivalina, an Inupiat Eskimo village of 400 perched on a barrier island north of the Arctic Circle, is accusing two dozen fuel and utility companies of helping to cause the climate change that it says is accelerating the island’s erosion.

The Deepwater Horizon accident in the Gulf of Mexico is a disaster unfolding before our eyes. Eleven lives were lost in the initial explosion, and that incalculable loss is compounded daily as oil continues to flow from the wellhead despite efforts on the part of BP and TransOcean to quell it. No one can accurately predict how long it will take to cap the leaking wellhead: it could be a matter of days, weeks, months. And regardless of how long it takes to staunch the flow of oil, the impacts of the oil spill on the people, economy and environment of Gulf coast states will persist for decades.

Here in Alaska, the impacts of the Exxon Valdez oil spill that took place more than 21 years ago are still being felt by people, communities, and the environment. You can still see a “bathtub ring” of Exxon’s oil in Prince William Sound, and you don’t have to dig very deep to find oil lingering below rocks on beaches. Exxon Valdez oil is still being ingested by wildlife more than two decades after the spill, and many species have yet to recover

Scientists have uncovered what appears to be a further dramatic increase in the leakage of methane gas that is seeping from the Arctic seabed.

Methane is about 20 times more potent than CO2 in trapping solar heat.

The findings come from measurements of carbon fluxes around the north of Russia, led by Igor Semiletov from the University of Alaska at Fairbanks.

A study out of the University of Colorado at Boulder shows that a substantial piece of the northern Alaska coastline is eroding at an astonishing rate of 45 feet a year thanks to three major threats - less ice, more waves, and warmer water.

The state will sue over increased federal protections for beluga whales in Cook Inlet, officials announced Wednesday.

The white whales were listed last year as endangered under the Endangered Species Act after federal scientists determined the whales were headed toward extinction.
