Earth Changes
Winds knocked over a big rig early Thursday in San Bernardino County below the Cajon Pass, NBCLosAngeles.com reported. No injuries were reported.
While this week's winds could be a serious hazard, they weren't forecast to approach the magnitude of a storm on Nov. 30 that spawned gusts approaching 100 mph. In that storm, trees were toppled, power poles snapped, homes were damaged and electricity was cut to nearly 650,000 homes and businesses.
This time around, northeast winds could reach 65 mph in many mountain areas and 40 mph in the valleys, the National Weather Service warned.
High-wind warnings were in effect from 1 a.m. PT Thursday to 1 p.m. PT Friday in Orange, Riverside and San Bernardino counties, it said.
Isolated gusts greater than 70 mph were possible below the Cajon and Banning passes in the Santa Ana Mountains, the weather service added.
"The winds will make driving difficult, especially for motorists with high profile vehicles. ... Watch for broken tree limbs and downed power lines," it said.
Southern California Edison on Wednesday night alerted customers to take precautions because of powerful winds that are expected to blow across Southern California, the LA Times reported.
In the Pasadena area, one of the hardest hit by the November storm, crews are still clearing debris. "Work crews are working in 12-hour shifts," said city spokeswoman Ann Erdman. "They continue, night and day, to get the debris picked up. ... We have a ways to go."
A "culture of cover up" and inadequate cleanup efforts have combined to leave Japanese people exposed to "unconscionable" health risks nine months after last year's meltdown of nuclear reactors at the Fukushima Dai-ichi power plant, health experts say. Although the Japanese government has declared the plant virtually stable, some experts are calling for evacuation of people from a wider area, which they say is contaminated with radioactive fallout.
They're also calling for the Japanese government to reinstate internationally-approved radiation exposure limits for members of the public and are slagging government officials for "extreme lack of transparent, timely and comprehensive communication."
But temperatures inside the Fukushima power station's three melted cores have achieved a "cold shutdown condition," while the release of radioactive materials is "under control," according to the International Atomic Energy Agency. That means government may soon allow some of the more than 100,000 evacuees from the area around the plant to return to their homes. They were evacuated from the region after it was struck with an 8.9magnitude earthquake and a tsunami last March 11.

The crippled Fukushima Dai-ichi nuclear power station is seen through a bus window in Okuma on November 12, 2011.
Nuclear crisis minister Goshi Hosono suggested that the timetable was ambitious, acknowledging that decommissioning three reactors with severely melted fuel plus spent fuel rods at the Fukushima Dai-ichi plant was an "unprecedented project," and that the process was not "totally foreseeable."
"But we must do it even though we may face difficulties along the way," Hosono told a news conference.
Under a detailed roadmap approved earlier Wednesday following consultation with experts and nuclear regulators, plant operator Tokyo Electric Power Co. will start removing spent fuel rods within two to three years from their pools located on the top floor of each of their reactor buildings.
The influenza virus, known as H3N8, appears to have a low risk for transmission to humans, they said. But officials are urging the public to be cautious about approaching stranded seals to reduce the potential risk of spreading the infection to people or their unleashed dogs.
"Influenza that poses a risk to people are human strains of influenza. . . . but there have been documented cases in people of transmission from other species,'' said Dr. Catherine M. Brown, public health veterinarian for the Massachusetts Department of Public Health.
Other viruses that caused global disease outbreaks in years past, such as avian and swine flu, jumped from birds and pigs to humans, usually through the animals' caretakers, Brown said. She said there has been an increasing number of instances in the past decade of flu viruses jumping from one species to another.

The tsunami triggered by the magnitude 9.0 earthquake that struck Japan in March devastated coastal areas. This photo of the town of Onagawa as taken April 8, 2011. The Pacific Northwest sits atop a fault zone much like the one that ruptured the sea floor off Japan, killing thousands.
A somewhat reassuring new study suggests otherwise.
University of California researchers examined the timing of earthquakes worldwide from 1900 and found no evidence of a domino effect in which one great earthquake triggers others on distant continents. It could be random chance.
"We don't want people to assume that our conclusion means the ongoing risk is small," says study co-author Peter Shearer, a professor of geophysics at the University of California San Diego. "There is a significant risk of big earthquakes in all subduction zones." It's just that the run of very large earthquakes most likely does nothing to change the risk in distant locations, Shearer says.

Researchers warn that Boswellia trees, which are tapped to make frankincense, are declining at a troubling rate.
Tapped from various species of the Boswellia tree that grow in the Horn of Africa and the Arabian Peninsula, frankincense has been traded internationally for thousands of years. However, researchers warn that the trees are declining at a troubling rate.
Ecologists from the Netherlands and Ethiopia monitored Boswellia trees growing in 13 plots of about 65 acres (2 hectares) each located in northwest Ethiopia, near the source of the Blue Nile river. The plots contained trees that were tapped for frankincense, as well as some that were left untapped. The researchers studied the survival, growth and seed production of more than 6,000 Boswellia trees over the course of two years.
Based on their finding, the researchers created demographic models to predict the fate of Boswellia populations. They estimate that the production of frankincense could drop to half over the next 15 years, and the number of Boswellia trees could decline by 90 percent in the next 50 years.

The entire north India shivered on Monday as 11 more people succumbed to the cold sweeping the region pushing the death toll to 39.
The death count from the harsh weather has risen to 30 in Uttar Pradesh where Fatehgarh with a minimum temperature of 3.9 degrees was the coldest place in the state. The national capital woke up to a thick blanket of fog which reduced the visibility to almost zero in some areas and disrupted rail and air traffic.
Dense fog also hit rail services in the region with over 40 trains running behind schedule, a railway spokesperson said.
Cold conditions prevailed in Kashmir with the minimum temperatures dropping several degrees below freezing point as the weather department forecast light to moderate snowfall at many places. Sub-zero night temperatures have resulted in freezing of water supply lines in many areas. Mercury in the skiing resort of Gulmarg in north Kashmir plummeted to a minimum of minus 6.8 degrees Celsius.
For a morning, the sky looked like a surfer's dream: A series of huge breaking waves lined the horizon in Birmingham, Ala., on Friday (Dec. 16), their crests surging forward in slow motion. Amazed Alabamans took photos of the clouds and sent them to their local weather station, wondering, "What are these tsunamis in the sky?"
Experts say the clouds were pristine examples of "Kelvin-Helmholtz waves." Whether seen in the sky or in the ocean, this type of turbulence always forms when a fast-moving layer of fluid slides on top of a slower, thicker layer, dragging its surface.
Water waves, for example, form when the layer of fluid above them (i.e., the air) is moving faster than the layer of fluid below (i.e., the water). When the difference between the wind and water speed increases to a certain point, the waves "break" - their crests lurch forward - and they take on the telltale Kelvin-Helmholtz shape.
According to Chris Walcek, a meteorologist at the Atmospheric Sciences Research Center at the State University of New York, Albany, fast-moving air high in the sky can drag the top of slow-moving, thick clouds underneath it in much the same way.

Four people died on Monday in a car wreck in New Mexico said Mark Wiley, a meteorologist with the National Weather Service.
And in eastern Colorado, a prisoner and a corrections officer were killed when the driver of a van transporting nine prisoners lost control on Interstate 70, authorities said.
An additional five people also died in a single-engine plane crash in Central Texas on Monday, but the crash was not near the severe weather in the Texas Panhandle.

Soldiers carry coffins of flash flood victims during a mass burial Tuesday at a cemetery in Iligan.
The latest count listed 957 dead and 49 missing and is expected to climb further as additional bodies are recovered from the sea and mud in Iligan and Cagayan de Oro cities.
A handful of morgues are overwhelmed and running out of coffins and formaldehyde for embalming. Aid workers appealed for bottled water, blankets, tents and clothes for many of 45,000 in crowded evacuation centers.
Navy sailors in Manila loaded a ship with 437 white wooden coffins to help local authorities handle the staggering number of dead. Also on the way were containers with thousands of water bottles.
