Adelaide heatwave 'one in 3,000 year' event

Adelaide's 15-day heatwave was a once in 3,000 year occurrence, an atmospheric scientist says.

Adelaide has sweltered through 15 consecutive days above 35 degrees - the longest heatwave recorded in any Australian capital city.

CA, US: Late winter storm blows in wind, rain, hail and snow

Bobbi Bennett awoke early yesterday to the sounds of pounding. Bennett, 54, a Pacific Beach resident, didn't need to get out of bed. She knew precisely the source: hail. And it was plenty loud.

"It sounded like little hammers," Bennett said. "Just a whole bunch of little hammers."

The unusual weather was part of a winter storm that blew through the county from the Gulf of Alaska. With it came wind, rain, snow and hail.

Melting Ice Sheets Can Cause Earthquakes, Study Finds

As ice sheets melt, they can release pent-up energy and trigger massive earthquakes, according to new study.

Global warming may already be triggering such earthquakes and may cause more in the future as ice continues to melt worldwide, the researchers say.

A series of large earthquakes shook Scandinavia around 10,000 years ago, along faults that are now quiet, the scientists point out.

The timing of each earthquake roughly coincided with the melting of thick ice sheets from the last ice age in those same places.

Alaska's Columbia Glacier has been retreating in recent years.

A new study has found that melting ice sheets can release pent-up energy and trigger massive earthquakes. A separate, earlier study found that small earthquakes were more common in Alaska in the summers, when ice there was melting.


Bird uses 'whiskers' like a cat

Fancy feathers are usually thought to be just ornaments, but a pair of biologists has shown that a little seabird uses the plumes on its head like a cat's whiskers to feel its way through dark crevices.

Aptly named whiskered auklets (Aethia pygmaea ) breed on the volcanic Aleutian and Kuril Islands that rim the north Pacific. They lay their eggs in small chambers reached by narrow passageways through jagged lava rocks, which they enter and leave only at night.

Chinook salmon vanish without a trace

The Chinook salmon that swim upstream to spawn in the fall, the most robust run in the Sacramento River, have disappeared. The almost complete collapse of the richest and most dependable source of Chinook salmon south of Alaska left gloomy fisheries experts struggling for reliable explanations — and coming up dry.


Katrina aftermath erodes bayou culture

GRAND BAYOU, La. - When Ruby Ancar talks about her fishing village on the bayou, she says a divine hand has protected her Atakapa-Ishak kinfolk for generations.

But Grand Bayou is forsaken these days, 30 months after Hurricane Katrina washed over it and dragged one of Louisiana's last authentic outposts of bayou culture into a world defined by insurers, money lenders, building code enforcers and government auditors.

Vast storm damage to parks in Northwest

YAKIMA, Wash. - Hundreds of trees blown down by wind exceeding 100 mph. Roads and campgrounds washed away by swollen rivers. Damages still unknown to be repaired on backcountry trails.

Winter storms have devastated the Pacific Northwest's popular national parks each of the past two years, causing damage that has run into the millions of dollars.

Andrew Pratt, of Quigg Bros. Construction, based in Aberdeen, Wash., uses backhoe Friday, March 7, 2008, to build a rock wall on a bank of the Quinault River where it washed out a portion of North Shore Road in Olympic National Park in Washington state. Even though volunteer crews are making the park the focus of their efforts this year -- joining workers at Mount Rainier and North Cascades national parks in their storm clean-up efforts -- summer visitors will still have to sidestep some storm damage.
