Severe Weather More Likely Thanks to Climate Change

Jane J. Lee

BOSTON—Wildfires. Droughts. Super storms.

As opposed to representing the unfortunate severe weather headlines of the last year, scientists said Friday that climate change has increased the likelihood of such events moving forward.

And though the misery is shared from one U.S. coast to another, scientists speaking at the annual American Association for the Advancement of Science meeting in Boston said, the type of extreme event may vary significantly from region to region. (Related: "6 Ways Climate Change Will Affect You.")

Heat waves have become more frequent across the United States, with western regions setting records for the number of such events in the 2000s, said Donald Wuebbles, a geoscientist with the University of Illinois at Urbana-Champaign.

But the Midwest and Northeast have experienced a 45 percent and 74 percent increase, respectively, in the heaviest rainfalls those regions have seen since 1950.

The extreme drought that plagued Texas in 2011 has spread to New Mexico, Louisiana, Oklahoma, and northern Mexico, said John Nielsen-Gammon, Texas State's climatologist at Texas A&M University in College Station.

"The science is clear and convincing that climate change is happening and it's happening rapidly. There's no debate within the science community ... about the changes occurring in the Earth's climate and the fact that these changes are occurring in response to human activities," said Wuebbles.

In 2011 and 2012, major droughts, heat waves, severe storms, tornadoes, floods, hurricanes, and wildfires caused about $60 billion in damages each year, for a total of about $120 billion.

According to the National Oceanic and Atmospheric Administration Climactic Data Center, these were some of the costliest weather events in the country's history, said Wuebbles.

President Obama argued in his State of the Union address this week that the time is ripe to address climate change, saying he would skirt Congress to make such changes, if necessary.

His proposals included a system similar to the cap-and-trade proposal killed in Congress during his first term, new regulations for coal-burning power plants, and a promise to promote energy efficiency and R&D efforts into cleaner technologies. (Related: "Obama Pledges U.S. Action on Climate, With or Without Congress.")

The researchers said they are glad to see that addressing climate change is on the President's agenda. But they stressed that they wanted the public to have access to accurate, scientifically sound information, not just simplified talking points.

Carnival Cruise Ship Hit With First Lawsuit

The first lawsuit against Carnival Cruise Lines has been filed and it is expected to be the beginning of a wave of lawsuits against the ship's owners.

Cassie Terry, 25, of Brazoria County, Texas, filed a lawsuit today in Miami federal court, calling the disabled Triumph cruise ship "a floating hell."

"Plaintiff was forced to endure unbearable and horrendous odors on the filthy and disabled vessel, and wade through human feces in order to reach food lines where the wait was counted in hours, only to receive rations of spoiled food," according to the lawsuit, obtained by ABCNews.com. "Plaintiff was forced to subsist for days in a floating toilet, a floating Petri dish, a floating hell."

The filing also said that during the "horrifying and excruciating tow back to the United States," the ship tilted several times "causing human waste to spill out of non-functioning toilets, flood across the vessel's floors and halls, and drip down the vessel's walls."

Terry's attorney Brent Allison told ABCNews.com that Terry knew she wanted to sue before she even got off the boat. When she was able to reach her husband, she told her husband and he contacted the attorneys.

Allison said Terry is thankful to be home with her husband, but is not feeling well and is going to a doctor.

"She's nauseated and actually has a fever," Allison said.

Terry is suing for breach of maritime contract, negligence, negligent misrepresentation and fraud as a result of the "unseaworthy, unsafe, unsanitary, and generally despicable conditions" on the crippled cruise ship.

"Plaintiff feared for her life and safety, under constant threat of contracting serious illness by the raw sewage filling the vessel, and suffering actual or some bodily injury," the lawsuit says.

Despite having their feet back on solid ground and making their way home, many passengers from the cruise ship are still fuming over their five days of squalor on the stricken ship and the cruise ship company is likely to be hit with a wave of lawsuits.

"I think people are going to file suits and rightly so," maritime trial attorney John Hickey told ABCNews.com. "I think, frankly, that the conduct of Carnival has been outrageous from the get-go."

Hickey, a Miami-based attorney, said his firm has already received "quite a few" inquiries from passengers who just got off the ship early this morning.

"What you have here is a) negligence on the part of Carnival and b) you have them, the passengers, being exposed to the risk of actual physical injury," Hickey said.

The attorney said that whether passengers can recover monetary compensation will depend on maritime law and the 15-pages of legal "gobbledygook," as Hickey described it, that passengers signed before boarding, but "nobody really agrees to."

One of the ticket conditions is that class action lawsuits are not allowed, but Hickey said there is a possibility that could be voided when all the conditions of the situation are taken into account.

One of the passengers already thinking about legal action is Tammy Hilley, a mother of two, who was on a girl's getaway with her two friends when a fire in the ship's engine room disabled the vessel's propulsion system and knocked out most of its power.

"I think that's a direction that our families will talk about, consider and see what's right for us," Hilley told "Good Morning America" when asked if she would be seeking legal action.

Sand-grain-sized drum extends reach of quantum theory

The banging of a tiny drum heralds the intrusion of the weird world of quantum mechanics into our everyday experience. Though no bigger than a grain of sand, the drum is the largest object ever to have been caught obeying the uncertainty principle, a central idea in quantum theory.

As well as extending the observed reach of quantum theory, the finding could complicate the hunt for elusive gravitational waves : it suggests that the infinitesimal motion caused by these still-hypothetical ripples in spacetime could be overwhelmed by quantum effects.

The uncertainty principle says that you cannot simultaneously determine both a particle's exact position and momentum. For example, bouncing a photon off an electron will tell you where it is, but it will also change the electron's motion, creating fresh uncertainty in its speed.

This idea limits our ability to measure the properties of very small objects, such as electrons and atoms. The principle should also apply to everyday, macroscopic objects, but this has not been tested – for larger objects, the principle's effects tend to be swamped by other uncertainties in measurement, due to random noise, say.

Quantum drum

To extend the known reach of the uncertainty principle, Tom Purdy and colleagues of the University of Colorado, Boulder, created a drum by tightly stretching a 40-nanometre-thick sheet of silicon nitride over a square frame with sides of half a millimetre – about the width of a grain of sand. They placed the drum inside a vacuum chamber cooled to a few degrees above absolute zero, minimising any interference by random noise.

By continuously firing a stream of photons at the drum they were able to get increasingly precise measurements of the position of the skin at any moment. However, this also caused the skin to vibrate at an unknown speed. When they attempted to determine its momentum, the error in their measurement had increased – just as the uncertainty principle predicts.

"You don't usually have to think about quantum mechanics for objects you can hold in your hand," says Purdy.

That the uncertainty principle holds sway at such a large scale could affect the hunt for gravitational waves, which are predicted by Einstein's theory of general relativity but have never been detected.

Mitigation strategy

Gravitational wave detectors look for very slight changes in the distance between two test masses caused by passing spacetime ripples. Purdy says his team's experiment confirms long-held suspicions that quantum uncertainty could overwhelm these very small changes.

Now he and others can use the drum to explore more advanced measurement techniques to mitigate the effects. For example, uncertainty in an object's momentum could lead to future uncertainty in its position and there should be ways to minimise such knock-on effects. "You can't avoid the uncertainty principle, but you can in some clever ways make it [such that] increasing the momentum doesn't add back to the uncertainty in position at a later time," says Purdy.

His experiment is a neat demonstration of the breakdown of the traditional notion that the atomic world is quantum while the macroscopic world is classic, says Gerard Milburn of the University of Queensland in Brisbane, Australia, who was not involved in the work. Previous, attempts to blur the quantum-classical divide have involved entangling diamonds and demonstrating quantum superposition in a strip of metal.

Despite these feats, Milburn doesn't rule out the prospect of a breakdown on really large scales. "Of course maybe one day we will see quantum mechanics fail at some scale. Testing it to destruction is a good motivation for going down this path," he says.

Smoking out tobacco: The rise of the e-cig

PARIS: The camera zooms in on a bearded man dragging on a cigarette and blowing out a thick cloud of smoke with what seems to be great satisfaction.

It resembles the TV smoking ads of yesteryear, now banned in most of the world, yet this modern-day offering is approved for American television viewers.

"You know what the most amazing thing about this cigarette is? It isn't one," explains a narrator as the modern-day Marlboro Man fixes the viewer with a broody stare before returning the reusable smoke to a container that resembles the traditional pocket-sized cardboard pack.

The NJOY "cigarette" is electronic -- its tip lights up with the help of an LED and what appears to be smoke is actually water vapour.

The actor is not smoking, but "vaping".

"Cigarettes, you have met your match," proclaims the ad for a product that claims to mimic "the look, feel and flavour of the real thing" -- minus the tar, ash, smoke and most toxins.

NJOY is one of a flurry of e-cigs entering the market as tobacco prices skyrocket and smokers become ever more concerned about the toxins they inhale.

But the jury is still out on whether the gadgets are safe or not.

"Without question, e-cigarettes are safer than traditional tobacco cigarettes," said Joel Nitzkin, of the American Association of Public Health Physicians.

"They deliver nicotine, with only the tiniest traces of other toxic chemicals."

But there are concerns that these battery-driven alternatives, officially called electronic nicotine delivery systems (ENDS), may pose health hazards we are not even aware of yet -- just like cigarettes before their ill-effects became clear.

"The safety of ENDS has not been scientifically demonstrated," the World Health Organisation said in response to a query.

"The potential risks they pose for the health of users remain undetermined."

The UN's health organ said some testing "suggests the presence of other toxic chemicals, aside from nicotine", and "strongly advised" consumers not to use them.

E-cigs first emerged in China in 2003 as an alternative to tobacco, which kills nearly six million people each year.

Just like their predecessors in the 1950s and 60s, electronic cigarettes are being advertised with attractive women and rugged, virile men -- hinting at a better, more popular you.

It's a strategy that seems to work.

A study in the American Journal of Preventive Medicine (AJPM) last month said 80 percent of users questioned in the United States, Britain, Canada and Australia believed e-cigarettes to be less harmful than their tobacco counterparts.

NJOY chief executive Craig Weiss told AFP that industry predictions are for electronic cigarette sales, which have doubled in the United States every year since 2008, to reach $1 billion (about 750,000 euros) in 2013.

"Growth in the category has occurred as a result of the millions of smokers who are actively seeking an alternative to cigarettes," he said by email.

The company would not comment on the health aspects.

According to Nitzkin, the hazard posed by traditional tobacco cigarettes is about 100 times higher than today's smokeless tobacco alternatives.

"When burned, cigarettes create a tarry residue that sticks to the inside of the smallest bronchial tubes of the lungs and in the alveoli, where the body absorbs the oxygen and releases the carbon dioxide.

"This tarry residue stays in place 24 hours a day, seven days a week for the life of the smoker," he said -- a side-effect that ENDS do not have.

Yet the European Respiratory Society said this month it could not classify e-cigs as a safe alternative to smoking, and stressed the principle that tobacco users "should not trade one carcinogenic product for another".

Last month, the UK's Advertising Standards Authority banned an ad for an e-cigarette, Nicolites, saying: "claims that the product was not harmful had not been substantiated".

Some researchers have also expressed concerns that non-smokers may get hooked on nicotine through e-cigarette use, or that the gadget would keep people addicted to nicotine who might otherwise have quit.

Nicotine can be harmful to children, pregnant women and adults with heart disease.

A recent study among 3,400 high school pupils in France showed that 12 percent of 15-to-16-year-olds who claimed never to have smoked before had experimented with ENDS, and 19 percent of 17-year-olds.

"As a doctor, I cannot recommend the electronic cigarette," lung specialist Bertrand Dautzenberg told AFP recently at the Pitie-Salpetriere hospital in Paris.

"But I would not interfere with a smoker who wants to take it up. With a cigarette, there is a 50 percent chance of killing oneself. With the electronic cigarette, we aren't too sure yet, but it is probably less," he said.

Iceland works to block Internet porn

If Iceland's Interior minister gets enough support, his country could be the first in the West to ban all Internet pornography. Ogmundur Jonasson is working on new legal measures that could make access to online porn nearly impossible, according to the Daily Mail.

"We have to be able to discuss a ban on violent pornography, which we all agree has a very harmful effects on young people and can have a clear link to incidences of violent crime," Jonasson told the Daily Mail. He added that the move isn't about censorship but rather the safety of women who appear in porn and children who may be exposed to it.

Jonasson's proposals include blocking porn IP addresses and making it illegal to use Iceland-based credit cards on X-rated Web sites.

Iceland has long held an adversarial stance against pornography. According to the Daily Mail, the country has already made it illegal to print and distribute porn. Now, Jonasson seems to want to bring Iceland's laws up to the Internet age.

The country's move to prohibit all porn stems from a 2010 government study. The study found that the violent nature of pornographic photos and videos, which are widely available on the Internet, have increased the rate of sexual abuse and rape in the country. It also concluded that children who were exposed to violent pornography showed signs of trauma.

Several other countries have tried to block online porn. In July, Indonesia shut down 1 million porn sites, and in November, Egypt also attempted to censor online pornography by blocking Web sites.

Like Iceland, the U.K. has also worked to keep Internet porn away from children. Last year, the government suggested putting rules on how X-rated sites are accessed. These rules included content filters where ISP customers would receive, by default, a filtered version of the Internet. Customers who did not want restricted Internet access would have to "opt in" to get the Internet uncensored.

Iceland's plan to totally block Internet porn seems to take the U.K.'s idea one step further.

"There is a strong consensus building in Iceland. We have so many experts from educationalists to the police and those who work with children behind this, that this has become much broader than party politics," Jonasson's political adviser Halla Gunnarsdottir told the Daily Mail. "At the moment, we are looking at the best technical ways to achieve this. But surely if we can send a man to the moon, we must be able to tackle porn on the Internet."

Why We Walk … and Run … And Walk Again to Get Where We're Going

You have to get to a bus stop to catch the once-an-hour express ... or to a restaurant to meet a friend ... or to a doctor's office. You've got maybe a half a mile to cover and you're worried you'll be late. You run, then you stop and walk, then run some more.

But wait. Wouldn't it be better to run the whole way?

Not necessarily.

A new study by an assistant professor of mechanical engineering at Ohio State University tests the theory that people subconsciously mix walking and running so they get where they need to. The idea is that "people move in a manner that minimizes energy consumption," said the professor, Manoj Srinivasan.

Srinivasan asked 36 subjects to cover 400 feet (122 meters), a bit more than the length of a football field. He gave them a time to arrive at the finish line and a stopwatch. If the deadline was supertight, they ran. If they had two minutes, they walked. And if the deadline was neither too short nor too far off, they toggled between walking and running.

The takeaway: Humans successfully make the walk-run adjustment as they go along, based on their sense of how far they have to go. "It's not like they decide beforehand," Srinivasan said. (Get tips, gear recommendations, and more in our Running Guide.)

The Best Technique for "the Twilight Zone"

"The mixture of walking and running is good when you have an intermediate amount of time," he explained. "I like to call it 'the Twilight Zone,' where you have neither infinite time nor do you have to be there now."

That ability to shift modes served ancient humans well. "It's basically an evolutionary argument," Srinivasan said. A prehistoric human seeking food would want to move in a way that conserves some energy so that if food is hard to find, the hunter won't run out of gas—and will still be able to rev it up to escape predators.

The study, published on January 30 in the Journal of the Royal Society Interface, doesn't answer that question of how we make such adjustments.

Runners: Take a Break if You Need It

The mix of walking and running is also something that nonelite marathoners are familiar with. Covering 26.2 miles might take less of a toll if the runner stops running from time to time, walks a bit, then resumes a jogging pace. "You use less energy overall and also give yourself a bit of a break," Srinivasan noted. (Watch: An elite marathoner on her passion for running.)

One take-home lesson is: Runners, don't push it all the time. A walk-run mix will minimize the energy you expend.

Lesson two: If you're a parent walking with your kid, and the kid lags behind, then runs to catch up, then lags again, the child isn't necessarily trying to annoy you. Rather, the child is perhaps exhibiting an innate ability to do the walk-run transition.

Potential lesson three: The knowledge that humans naturally move in a manner that minimizes energy consumption might be helpful in designing artificial limbs that feel more natural and will help the user reduce energy consumption.

The big question for Manoj Srinivasan: Now that he has his walk-run theory, does he consciously switch between running and walking when he's trying to get somewhere? "I must admit, no," he said. "When I want to get somewhere, I just let the body do its thing." But if he's in a rush, he'll make a mad dash.

"Talk to you tomorrow," he signed off in an email to National Geographic News. "Running to get to teaching now!"

Disabled Cruise Ship Reaches Port in Mobile, Ala.

The ordeal of the disabled Carnival Triumph cruise ship carrying 4,000 passengers and crew appears to be almost over, with relatives waving at passengers on board as the ship reached port in Mobile, Ala.

After the ship arrived around 9:30 p.m. local time (10:30 p.m. ET), Carnival president and CEO Gerry Cahill thanked the ship's crew for coping with the situation and told reporters that he was headed on board to apologize directly to its passengers.

The Carnival Triumph departed Galveston, Texas, Thursday and lost power Sunday after a fire in the engine room disabled the vessel's propulsion system and knocked out most of its power.

After power went out, passengers texted ABC News that sewage was seeping down the walls from burst plumbing pipes, carpets were wet with urine, and food was in short supply. Reports surfaced of elderly passengers running out of critical heart medicine and others on board the ship squabbling over scarce food.

"I know the conditions on board were very poor," Cahill said. "I know it was very difficult, and I want to apologize again for subjecting our guests for that. ... Clearly, we failed in this particular case."

Once the ship is secured, passengers were expected to be able to begin disembarking within 15 to 30 minutes, said Terry Thornton, Carnival's senior vice president of marketing.

It could take up to five more hours to get everybody off the huge ship.

"Inside the terminal, there's also warm food available," Thornton said. "There are blankets, there are cell phones and refreshments available for the guests that need that or want that assistance.

Passengers will have the options of boarding buses to Houston or Galveston, Texas, about seven hours away, or New Orleans, about two hours away, officials said.

"We have gotten our guests back to land," Cahill said. "Now, we need to get them home. ... The full resources of Carnival are working from here to get them home as quickly as we possibly can."

At an earlier news conference this afternoon, Thornton said that anyone with special needs and children will be the first to get off the boat. He said the company's number one priority is to make the process as "quick, efficient and comfortable" for guests as possible.

"There are some limitations. We know that up front," Thornton said. "The ship still does not have power. We only have one functioning elevator aboard."

Click here for photos of the stranded ship at sea.

The passengers were achingly close to port about noon today as the ship began to enter the channel and proceed to the cruise terminal. At 1 p.m., the lead tow boat had a tow gear break, so a spare tug boat that was on standby had to be sent in to replace it.

But once the second tug was in position and the lines were re-set, the towing resumed only briefly before the tow line snapped.

"We had to replace that tow line so the ship did not begin progressing back into the cruise terminal until 2 p.m.," Thornton said

Passengers desperate to get off the vessel waved at media helicopters that flew out to film the ship and passenger Rob Mowlam told ABCNews.com by phone today that most of the passengers on board were "really upbeat and positive."

Nevertheless, when he gets off Mowlam said, "I will probably flush the toilet 10 times just because I can."

Mowlam, 37, got married on board the Triumph Friday and said he and his wife, Stephanie Stevenson, 27, haven't yet thought of redoing the honeymoon other than to say, "It won't be a cruise."

Alabama State Port Authority Director Jimmy Lyons said that with powerless "dead ships" like the Triumph, it is usually safer to bring them in during daylight hours, but, "Once they make the initial effort to come into the channel, there's no turning back."

"There are issues regarding coming into the ship channel and docking at night because the ship has no power and there's safety issues there," Richard Tillman of the Mobile Bay Convention and Visitors Bureau told ABCNews.com.

When asked if the ship could be disembarked in the dark of night, Tillman said, "It is not advised. It would be very unusual."

Thornton denied the rumors that there was a fatality on the ship. He said that there was one illness early on, a dialysis patient, but that passenger was removed from the vessel and transferred to a medical facility.

The U.S. Coast Guard was assisting and there were multiple generators on board. Customs officials were to board the ship while it was being piloted to port to accelerate the embarkation, officials said.

Chavez in 'tough' alternative treatment: Maduro

CARACAS: Venezuela's President Hugo Chavez is undergoing "tough and complex" alternative medical treatment in Cuba, his handpicked successor Nicolas Maduro said Wednesday.

"Our comandante is undergoing additional treatments," Maduro told state-owned VTV television after returning from a previously unannounced visit to Cuba to check up on the ailing president.

"The treatments are extremely tough and complex."

Declining to provide details about the therapy, the vice president insisted that Chavez was facing his medical travails with a "fighting spirit" despite more than two months of absence from the public eye.

Maduro said Chavez's brother Adan accompanied him on his trip to Havana, and that he met there with other relatives of the president, as well as his medical team.

National Assembly President Diosdado Cabello was due to visit Chavez in Cuba in the coming days, according to Maduro.

Chavez, 58, has not been seen or heard from since his last cancer operation on December 11 in Havana, and any news about his health is closely monitored by the Venezuelans. Chavez is said to be still recovering at a hospital in Cuba's capital.

The fiery Venezuelan leader was too sick to attend his own inauguration to a third term on January 10, prompting the government to delay the swearing-in indefinitely under an interpretation of the constitution that was heavily criticized by the opposition.

Throughout his illness, first detected in June 2011, Chavez has refused to relinquish the powers of the presidency.

To their shock and horror, Owen Wilson and Vince Vaughn realize that by landing an internship at Google they are actually "looking at some sort of mental 'Hunger Games' against a bunch of genius kids for just a handful of jobs."

This scene is shown in the newly out trailer (see below) for the upcoming movie titled "The Internship." The film features the two "Wedding Crashers" stars as they try to make it in the world of Google's high-tech interns. The only catch is that they're "so old" and aren't exactly tech savvy.

The trailer shows the two friends as they try to make sense of a Rubik's cube contest, a see-through dry-erase wall, and how to "debug the code" on Google's famous campus.

According to The Sun, Google has been very supportive about the use of its campus and facilities for the film. "We're excited that Vince Vaughn and Owen Wilson chose the Google campus as a backdrop for their first film together since Wedding Crashers," Google told The Sun. "We're sure they'll have a humorous take on life in Silicon Valley and look forward to seeing the result."

"The Internship" is one of many tech world-focused movies to grace the silver screen in the last couple of years. Aaron Sorkin's "The Social Network" showed the inside world of Facebook's Mark Zuckerberg, and two movies on Steve Jobs are in the works. One called "Jobs" is starring Ashton Kutcher and the other directed by Aaron Sorkin is based on the bestselling book by Walter Isaacson called "Steve Jobs."

"The Internship" is set to premiere this June. Here's the trailer:
