The warming Arctic could unleash larger-than-expected quantities of methane, a study asserts.

"Until now, models have predicted something for the future ... but it was something that seemed very distant,” said the lead researcher in a newly published study

There is so little recoverable oil and gas off California, Oregon and Washington that oil companies might not spend money on leases allowing potential exploration, the secretary said.

Over thousands of years, the Arctic has stored up massive amounts of carbon.

The frozen soils hold “twice as much mercury as the rest of all soils, the atmosphere, and ocean combined,” scientists wrote Monday.
