European scientists were alarmed in 2008 when they discovered streams of methane bubbles erupting from the seafloor in Norway's high Arctic. This gas, which contributes to global warming, was apparently coming from methane ice on the seafloor. A follow-up study finds that methane bubble plumes at this location have probably been forming for a few thousand years, so they are not the result of human-induced climate change. But continued warming of ocean water can trigger more methane releases in the Arctic, with potentially serious consequences to the climate.
In Lisbon, the waiting area of Portugal's biggest maternity hospital is empty. You can hear the hum of soda machines across the hall. There's just one expectant father, pacing the room.
Mario Carvalho, 40, has a toddler son and now awaits the birth of his baby girl.

The birth of a new baby is a joyous occasion. But in Portugal, it's an increasingly rare one. Since the economic crisis hit, the country's birthrate has dropped 14 percent, to less than 1.3 babies per woman โ one of the lowest in the world.
The U.S. Forest Service has proposed a large salvage logging operation in the area affected by last year's historic Rim Fire, which burned 410-square miles of California's Sierra Nevada. The proposal is meeting stiff opposition from environmental groups who say the land is better left untouched.
