Happy International Polar Bear Day!
Science reporter Deborah Netburn talked to the chief scientist for Polar Bears International, the conservation group that founded International Polar Bear Day, about ways people can help polar bears. Number one on the group’s list: turn your thermostat down a few degrees.

California’s calamitous drought drags on
It’s dry in California - historically dry. Water is in short supply, the air is noticeably without moisture, farms are parched and just look at the photo above of the state’s dwindling snow cover. It pretty much speaks for itself.
Meanwhile, various interests are turning to the political realm to try and ensure they get theirs when it comes to H2O.
And the drought has been particularly harsh on agriculture:
Ranchers have begun liquidating herds. Growers are considering tearing out thirsty tree crops such as nut orchards and citrus groves. And tens of thousands of additional acres of prime California soil could go unplanted if farmers don’t get enough water to irrigate them.

The dusty decimation of California’s drought
California’s longstanding drought has escalated in recent months, with 62.7% of the state now in what the Department of Agriculture deems “extreme” conditions.
But in few places is it as easily visualized as in the area surrounding the vanishing Cachuma Lake, which has become one of the most prominent victims of the lack of rain.
In years past, the spot where Bozarth was standing was under 30, 40, even 50 feet of water. It wasn’t all that long ago that Cachuma “spilled” — filled to the brim, to the point where millions of gallons of clean, fresh water was released through the dam’s gates and cast into the sea, a display of surplus that is laughable today.
That was only three years ago. Now, said Tom Fayram, Santa Barbara County’s deputy public works director, “it’s just empty.”

Los Angeles: Say goodbye to plastic bags
Starting with the new year, plastic bags will be banned from major grocery markets, with smaller stores to be forced to give up the bags starting in July. So L.A. residents be warned: Tomorrow is your last chance to have your groceries bagged in plastic in compliance with the law.
Unless, of course, your grocer of choice just decides to hand you a plastic bag anyway.

Green energy could crash the national power grid
Not because of any sort of explosive danger, but because the U.S. power grid is built for the previous century’s sources of energy. The antiquated grid, already a persistent cause for concern for officials, simply may not be prepared for large-scale adoption of alternative sources of power:
Green energy is the least predictable kind. Nobody can say for certain when the wind will blow or the sun will shine. A field of solar panels might be cranking out huge amounts of energy one minute and a tiny amount the next if a thick cloud arrives. In many cases, renewable resources exist where transmission lines don’t.

Wow: Typhoon Haiyan overlaid on a map of the United States
Some perspective on the "national calamity" that has struck the Philippines, with a death of at least 10,000 people expected by officials. You can donate to help the victims of the catastrophic storm via the Red Cross here.
CORRECTION: Before this is shared any further, the New Republic’s Nate Cohn has corrected the Red Cross’ image, with some help from Bran Dougherty-Johnson. In the center are the Philippines, with Typhoon Haiyan in the lower right.

Los Angeles Aqueduct bomber tells his side of the story
One of the men behind the series of aqueduct bombings in 1976, which struck three locations along the vital L.A. aqueduct, has opened up for the first time and recently spoke to reporter Louis Sahagun.
Mark Berry, who was just 17 at the time of the bombings, narrated the events leading up to the detonations:
Berry and his friend, Robert Howe, were caught up in the anger that then hung over the Owens Valley. The environmental damage caused by the Los Angeles Aqueduct, built in the early 1900s to divert much of the water from the region to the growing metropolis 200 miles away, was worsening and Owens Valley residents were exasperated.
"Things got out of hand," Berry recalled.
The friends stole two cases of dynamite and headed to the aqueduct.

Think L.A. has smog problems? Check out China’s ‘Airpocalypse’
Fueled by coal plants and burning fields, the thick haze has closed schools, clogged traffic and is prompted doctors to warn of widespread respiratory problems.
In Harbin, a city of 12 million world-famous for its wintertime ice festival, the smog was so thick that visibility was reduced to 20 yards. Municipal bus drivers lost their way in the haze. In one case, a morning rush hour bus that left at 5:30 wandered around for three hours before the driver found the route.

October 1, 1890: Yosemite Established as National Park
On this day in 1890, President Benjamin Harrison signed a bill into law creating Yosemite National Park. The mountainous region spanning 1,169 square miles of public land in the California Sierra Nevada preserves wilderness, wildlife, and public trust.

Just don’t try to visit today, since Yosemite is one of the many National Parks closed during the government shutdown.

Rim fire’s legacy burnt into landscape for decades to come
The Rim fire, which is still burning as its secured its legacy as California’s third-largest wildfire in history, so far has burned across nearly 402 square miles. Though the worst of the blaze is over, and officials expect it to be fully extinguished by October, the region’s recovery has barely begun:
Burned chaparral and oak will quickly resprout. But where large patches of trees were killed, ecologists say it could take 30 to 50 years for the forest to reestablish itself in the shrub fields that are the first to grow. If there are more fires in the meantime, the land could permanently convert to chaparral.

Cheer up, gloppy blobfish
You may have been voted the world’s ugliest endangered animal. Fine. You may look like a saggy old man who just dropped his ice cream cone. But you’re a winner! And maybe all of that publicity will help save your species.

The source of the record-breaking Rim fire revealed
The fire that burned 237,341 acres, requiring the efforts of more than 5,100 firefights to combat, all started with a single illegal fire set by a lone hunter, officials believe.
Dismissing an earlier rumor that the fire was sparked in an illegal marijuana farm, the Forest Service said Thursday that the hunter believed to be responsible has been identified, though he has yet to be arrested.
Meanwhile, the fire is currently 80% contained, and the fires aren’t expected to be completely extinguished for two weeks.

Meet the Hyperloop, the possible future of transportation
Tesla Motors CEO Elon Musk isn’t exactly one to dream small: Just look at his plan for a so-called Hyperloop transportation system, which would reach speeds of more than 700 mph, has just been officially unveiled.
While a network of tube transports that would make a trip from Los Angeles to San Francisco as short as 30 minutes seems ridiculous, remember that Musk is also leading SpaceX, which aims to commercialize space travel.
Said Musk in his unveiling of the Hyperloop:
When the California “high speed” rail was approved, I was quite disappointed, as I know many others were too. How could it be that the home of Silicon Valley and JPL – doing incredible things like indexing all the world’s knowledge and putting rovers on Mars – would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world?
As for how the whole thing works:
Hyperloop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. The capsules are supported on a cushion of air, featuring pressurized air and aerodynamic lift.
The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube with rotors contained in each capsule. Passengers may enter and exit Hyperloop at stations located either at the ends of the tube, or branches along the tube length
All of that said, there are no immediate plans to construct the loop, and that the project is currently “extremely speculative.”
