Predator and its prey: Orca whales snatch sea lion pups from beach

The park ranger gestured forcefully, ordering me to throw myself down on the sand and stay quiet.

Some sea lion pups paddled tentatively in the shallow surf, learning to swim at Punta Norte beach in eastern Patagonia, and we were staring at the sea, watching for a huge black fin.

It was my first visit to see orcas hunting baby sea lions on the Valdes peninsula, a natural phenomenon unique to the killer whale group in this region.

I tried to stick carefully to the instructions the park ranger gave us before leading us to a thin stretch of sand near the ocean where Mel, a giant orca, was preparing to hunt.

Best of the Web: Our climate numbers are a big old mess

"Why is the news on global warming always bad? Perhaps because there's little incentive to look at things the other way. If you do, you're liable to be pilloried by your colleagues. If global warming isn't such a threat, who needs all that funding? Who needs the army of policy wonks crawling around the world with bold plans to stop climate change?

But as we face the threat of massive energy taxes - raised by perceptions of increasing rates of warming and the sudden loss of Greenland's ice - we should be talking about reality."

Early typhoon hits southern China

More than 100,000 people had to be evacuated as Typhoon Neoguri battered China's southern province of Hainan. The typhoon - the first to threaten China this year - also left 3,000 passengers stranded at an airport after 76 flights were cancelled.

It began lashing Wenchang late on Friday night with winds of up to 108km/h (67 mph), and reports say it caused a black-out in the city. Neoguri has since been downgraded to a tropical storm.

US: Avalanches knock out power to Alaska's capital

Massive avalanches destroyed transmission lines and support towers to a dam that supplies 85 percent of the electricity for Alaska's capital, and utility rates could quintuple for months until repairs are made, officials said.

The series of avalanches hit at 4 a.m. Wednesday, taking out 1.5 miles of power transmission line and destroying or severely damaging five support towers along a steep mountainside outside the Snettisham Hydroelectric Facility, about 40 miles from downtown Juneau.

China evacuates 120,000 people as Typhoon Neoguri nears

About 120,000 people have been evacuated from fish farms and low-lying coastal areas to safer places in south China's Hainan Province as Typhoon Neoguri approaches the island.

The Hainan flood control authorities said that as of mid-day on Friday, 42,000 residents had been displaced in Wenchang, Qionghai, Wanning, Lingshui and Sanya. The evacuation of 5,500 others was still under way.

The island's fishing authorities have removed 80,000 fishermen from boats or fish farms.

Presumed Extinct Javan Elephants May Have Been Found Again - In Borneo

The Borneo pygmy elephant may not be native to Borneo after all. Instead, the population could be the last survivors of the Javan elephant race - accidentally saved from extinction by the Sultan of Sulu centuries ago, a new publication suggests.

The origins of the pygmy elephants, found in a range extending from the north-east of the island into the Heart of Borneo, have long been shrouded in mystery. Their looks and behaviour differ from other Asian elephants and scientists have questioned why they never dispersed to other parts of the island.

Ice Sheet 'Plumbing System' Found: Lakes Of Meltwater Can Crack Greenland's Ice And Contribute To Faster Ice Sheet Flow

Researchers from the Woods Hole Oceanographic Institution (WHOI) and the University of Washington (UW) have for the first time documented the sudden and complete drainage of a lake of meltwater from the top of the Greenland ice sheet to its base.

From those observations, scientists have uncovered a plumbing system for the ice sheet, where meltwater can penetrate thick, cold ice and accelerate some of the large-scale summer movements of the ice sheet.
