Te'o tells Couric 'pain' and 'sorrow' was real

NEW YORK (AP) — Manti Te'o told Katie Couric the feelings he had for what turned out to be a fake, online girlfriend were real and reiterated he had nothing to do with the hoax.

The All-American linebacker said he was truly sorrowful and pained after finding out the woman he knew as Lennay Kekua died in September.

Te'o's once-heartwarming tale of inspired play after the deaths of his grandmother and girlfriend on the same day in September was exposed as a bizarre hoax on Jan. 16. Deadspin.com broke the news that the woman Te'o had claimed to be in love with did not exist.

Te'o, who led Notre Dame to a spot in the national championship, has admitted that when his girlfriend's "death" became a story, he misled reporters into thinking he had met her in the flesh.

The star player recounted the whole, strange episode in an interview with Couric that was broadcast Thursday.

Wow! Dung Beetles Navigate by the Stars

Despite having tiny brains, dung beetles are surprisingly decent navigators, able to follow straight paths as they roll poo balls they’ve collected away from a dung source. But it seems the insects’ abilities are more remarkable than previously believed. Like ancient seafarers, dung beetles can navigate using the starry sky and the glow from the Milky Way, new research shows.

“This is the first time where we see animals using the Milky Way for orientation,” said lead researcher Marie Dacke, a biologist at Lund University in Sweden. “It’s also the first time we see that insects can use the stars.”

After locating a fresh pile of feces, dung beetles will often collect and roll away a large piece of spherical dung. Last year, Dacke and her colleagues discovered the beetles climb on their dung balls and dance around in circles before taking off. This dance is not one of joy, however; the insects are checking out the sky to get their bearings.

“The dorsal (upper) parts of the dung beetles‘ eyes are specialized to be able to analyze the direction of light polarization — the direction that light vibrates in,” Dacke told LiveScience. So when a beetle looks up, it’s taking in the sun, the moon and the pattern of ambient polarized light. These celestial cues help the beetle avoid accidentally circling back to the poo pile, where other beetles may try to steal its food, Dacke said. [Photos of Dung Beetles Dancing on Poop Balls]

In addition to these cues, Dacke and her team wondered if dung beetles can use stars for navigation, just as birds, seals and humans do. After all, they reasoned, dung beetles can somehow keep straight on clear, moonless nights.

To find out, the researchers timed how long dung beetles of the species Scarabaeus satyrus took to cross a circular arena with high walls blocking views of treetops and other landmarks. They tested the insects in South Africa under a moonlit sky, a moonless sky and an overcast sky. In some trials, the beetles were fitted with cardboard caps, which kept their eyes to the ground. Overall, the beetles had a difficult time traveling straight and took significantly longer to cross the arena if caps or clouds obstructed their view of the sky.

From the experiments, “we thought that they could be using the stars [for orientation], but dung beetles have such small eyes that they don’t have the resolution, or sensitivity, to see individual stars,” Dacke said.

So the researchers moved their setup into a planetarium to tease out the information the beetles were extracting from the starry sky. They repeated the experiment under several different conditions, such as showing only the brightest stars, showing only the diffuse band of the Milky Way and showing the complete starry sky. The beetles took about the same amount of time to cross the arena when only the Milky Way was visible as when they could see a full star-filled sky. And they were slower to cross under all other conditions.

Previous experiments showed another dung beetle, S. zambesianus, is unable to roll along straight tracks on moonless nights when Earth’s galaxy, the Milky Way, lies below the horizon, Dacke noted. Taken together, these results suggest dung beetles navigate using the gradient of light provided by the Milky Way. However, this technique would only work for beetles living in regions where the Milky Wayis distinct. “What they are doing in the Northern Hemisphere [of Earth], I don’t know,” she said.

The researchers are now trying to determine the relative importance of the different sky cues dung beetles use. “If they have the moon, polarized light and the Milky Way, will they use all cues equally?” Dacke said.

The research is published online today (Jan. 24) in the journal Current Biology.

Neanderthal cloning? Pure fantasy

A display of a reconstruction of a Neanderthal man and boy at the Museum for Prehistory in Eyzies-de-Tayac, France.

STORY HIGHLIGHTS

• Arthur Caplan: It would be unethical to try and clone a Neanderthal baby


• Caplan: Downsides include a good chance of producing a baby that is seriously deformed


• He says the future belongs to what we can do to genetically engineer and control microbes


• Caplan: Microbes can make clean fuel, suck up carbon dioxide, clean fat out of arteries

Editor's note: Arthur Caplan is the Drs. William F and Virginia Connolly Mitty professor and director of the Division of Bioethics at New York University Langone Medical Center.

(CNN) -- So now we know -- there won't be a Neanderthal moving into your neighborhood.

Despite a lot of frenzied attention to the intentionally provocative suggestion by a renowned Harvard scientist that new genetic technology makes it possible to splice together a complete set of Neanderthal genes, find an adventurous surrogate mother and use cloning to gin up a Neanderthal baby -- it ain't gonna happen anytime soon.

Nor should it. But there are plenty of other things in the works involving genetic engineering that do merit serious ethical discussion at the national and international levels.

Arthur Caplan

Some thought that the Harvard scientist, George Church, was getting ready to put out an ad seeking volunteer surrogate moms to bear a 35,000-year-old, long-extinct Neanderthal baby. Church had to walk his comments back and note that he was just speculating, not incubating.

Still cloning carries so much mystery and Hollywood glamour thanks to movies such as "Jurassic Park," "The Boys From Brazil" and "Never Let Me Go" that a two-day eruption of the pros and cons of making Neanderthals ensued. That was not necessary. It would be unethical to try and clone a Neanderthal baby.

Why? Because there is no obvious reason to do so. There is no pressing need or remarkable benefit to undertaking such a project. At best it might shed some light on the biology and behavior of a distant ancestor. At worst it would be nothing more than the ultimate reality television show exploitation: An "Octomom"-like surrogate raises a caveman child -- tune in next week to see what her new boyfriend thinks when she tells him that there is a tiny addition in her life and he carries a small club and a tiny piece of flint to sleep with him.

The downsides of trying to clone a Neanderthal include a good chance of killing it, producing a baby that is seriously deformed, producing a baby that lacks immunity to infectious diseases and foods that we have gotten used to, an inability to know what environment to create to permit the child to flourish and a complete lack of understanding of what sort of behavior is "normal" or "appropriate" for such a long-extinct cousin hominid of ours.

When weighed against the risks and the harm that most likely would be done, it would take a mighty big guarantee of benefit to justify this cloning experiment. I am willing to venture that the possible benefit will never, ever reach the point where this list of horrible likely downsides could be overcome.

Even justifying trying to resurrect a woolly mammoth, or a mastodon, or the dodo bird or any other extinct animal gets ethically thorny. How many failures would be acceptable to get one viable mastodon? Where would the animal live? What would we feed it? Who would protect it from poachers, gawkers and treasure hunters? It is not so simple to take a long dead species, make enough of them so they don't die of isolation and lack of social stimulation and then find an environment that is close enough and safe enough compared with that which they once roamed.

In any event the most interesting aspects of genetic engineering do not involve making humans or Neanderthals or mammoths. They involve ginning up microbes to do things that we really need doing such as making clean fuel, sucking up carbon dioxide, cleaning fat out of our arteries, giving us a lot more immunity to nasty bacteria and viruses and helping us make plastics and chemicals more efficiently and cheaply.

In trying to make these kinds of microbes, you can kill all you want without fear of ethical condemnation. And if the new bug does not like the environment in which it has to exist to live well, that will be just too darn bad.

The ethical challenge of this kind of synthetic biology is that it can be used by bad guys for bad purposes. Biological weapons can be ginned up and microbes created that only infect people with certain genes that commonly associate with racial or ethnic groups.

Rather than worry about what will happen to real estate values should a new crop of "Flintstones" move in down the street, our public officials, religious groups and ethicists need to get serious about how much regulation the genetic engineering of microbes needs, how can we detect what terrorists might try to use, what sort of controls do we need to prevent accidents and who is going to pay if a bug turns out to cause more harm than good.

We love to think that the key to tomorrow lies in what humanity can be designed or empowered to do. Thus, the fascination with human cloning. In reality, at least for a long time to come, the future belongs to what we can do to design and control microbes. That is admittedly duller, but it is far better to follow a story that is true than one such as Neanderthal cloning that is pure, speculative fantasy.

Girl: 'My sister's on fire'

3 children were injured, 1 critically after a fire started inside their apartment. (WGN - Chicago)

By Carlos Sadovi and Rosemary Regina Sobol




Tribune reporters

2:20 p.m. CST, January 24, 2013

Hearing screams in the hallway, Vanessa King stepped out of her apartment to see her neighbor rushing down the stairs while cradling a little girl crying from burns over half her body.

"He put a blanket around her. He was holding her. He was telling her it was going to be OK," King said.

The neighbor, Clyde Harden, carried the 4-year-old girl into an ambulance that took her to Comer Children's Hospital, where she remained in critical condition today.

The girl was with her 9-year-old brother and 16-year-old sister when her bunk bed caught fire around 7:15 p.m. Wednesday in a four-flat in the 1000 block of West 76th Street, officials said.

The 16-year-old was in a back bedroom doing her homework when the boy ran to her room, neighbors said. "He ran back there to tell her [their sister] was on fire," said Sandra Gray, who lives downstairs. "She came downstairs and was knocking on everyone's door. She was screaming, 'My sister's on fire.' "

Gray said she and her husband and a neighbor ran up and saw the bottom bunk bed on fire. "All I saw was that the bed was on fire and the baby was burned," Gray said. "You could see the bed on fire."

She said the 16-year-old tried to pull the little girl from the bed and burned her hands. Gray's husband and the neighbor finally put the fire out as firefighters and paramedics arrived, she said. Gray said the girl was conscious but badly burned.

Harden, who rushed up with Gray, said he grabbed hold of the girl and helped put out the fire. “I believe that she was sheltered by God already,” he told reporters on the scene. “Somebody was there for her.”

Though an official cause has not been determined, authorities are looking into the possibility that someone inside the home had been playing with a lighter or matches, according to Fire Department spokesman Larry Langford.

King said she was struggling with how to talk to her 5-year-old daughter about her friend’s injury, saying her girl had nightmares through the night.

King said her daughter told her that "my friend needs to get her skin back. The doctor is going to take care and God is going to take care of her."

North Korea to target U.S. with nuclear, rocket tests

SEOUL (Reuters) - North Korea said on Thursday it would carry out further rocket launches and a nuclear test that would target the United States, dramatically stepping up its threats against a country it called its "sworn enemy".

The announcement by the country's top military body came a day after the U.N. Security Council agreed to a U.S.-backed resolution to censure and sanction North Korea for a rocket launch in December that breached U.N. rules.

North Korea is not believed to have the technology to deliver a nuclear warhead capable of hitting the continental United States, although its December launch showed it had the capacity to deliver a rocket that could travel 10,000 km (6,200 miles), potentially putting San Francisco in range, according to an intelligence assessment by South Korea.

"We are not disguising the fact that the various satellites and long-range rockets that we will fire and the high-level nuclear test we will carry out are targeted at the United States," North Korea's National Defence Commission said, according to state news agency KCNA.

North Korea is believed by South Korea and other observers to be "technically ready" for a third nuclear test, and the decision to go ahead rests with leader Kim Jong-un, who pressed ahead with the December rocket launch in defiance of the U.N. sanctions.

China, the one major diplomatic ally of the isolated and impoverished North, agreed to the U.S.-backed resolution and it also supported resolutions in 2006 and 2009 after Pyongyang's two earlier nuclear tests.

Thursday's statement by North Korea represents a huge challenge to Beijing as it undergoes a leadership transition, with Xi Jinping due to take office in March.

China's Foreign Ministry called for calm and restraint and a return to six-party talks, but effectively singled out North Korea, urging the "relevant party" not to take any steps that would raise tensions.

"We hope the relevant party can remain calm and act and speak in a cautious and prudent way and not take any steps which may further worsen the situation," ministry spokesman Hong Lei told reporters at a regular press briefing.

North Korea has rejected proposals to restart the talks aimed at reining in its nuclear capacity. The United States, China, Russia, Japan and the two Koreas are the six parties involved.

"After all these years and numerous rounds of six-party talks we can see that China's influence over North Korea is actually very limited. All China can do is try to persuade them not to carry out their threats," said Cai Jian, an expert on Korea at Fudan University in Shanghai.

Analysts said the North could test as early as February as South Korea prepares to install a new, untested president or that it could choose to stage a nuclear explosion to coincide with former ruler Kim Jong-il's Feb 16 birthday.

"North Korea will have felt betrayed by China for agreeing to the latest U.N. resolution and they might be targeting (China) as well (with this statement)," said Lee Seung-yeol, senior research fellow at Ewha Institute of Unification Studies in Seoul.

U.S. URGES NO TEST

Washington urged North Korea not to proceed with a third test just as the North's statement was published on Thursday.

"Whether North Korea tests or not is up to North Korea," Glyn Davies, the top U.S. envoy for North Korean diplomacy, said in the South Korean capital of Seoul.

"We hope they don't do it. We call on them not to do it," Davies said after a meeting with South Korean officials. "This is not a moment to increase tensions on the Korean peninsula."

The North was banned from developing missile and nuclear technology under sanctions dating from its 2006 and 2009 nuclear tests.

A South Korean military official said the concern now is that Pyongyang could undertake a third nuclear test using highly enriched uranium for the first time, opening a second path to a bomb.

North Korea's 2006 nuclear test using plutonium produced a puny yield equivalent to one kiloton of TNT - compared with 13-18 kilotons for the Hiroshima bomb - and U.S. intelligence estimates put the 2009 test's yield at roughly two kilotons

North Korea is estimated to have enough fissile material for about a dozen plutonium warheads, although estimates vary, and intelligence reports suggest that it has been enriching uranium to supplement that stock and give it a second path to the bomb.

According to estimates from the Institute for Science and International Security from late 2012, North Korea could have enough weapons grade uranium for 21-32 nuclear weapons by 2016 if it used one centrifuge at its Yongbyon nuclear plant to enrich uranium to weapons grade.

North Korea has not yet mastered the technology needed to make a nuclear warhead small enough for an intercontinental missile, most observers say, and needs to develop the capacity to shield any warhead from re-entry into the earth's atmosphere.

North Korea gave no time-frame for the coming test and often employs harsh rhetoric in response to U.N. and U.S. actions that it sees as hostile.

The bellicose statement on Thursday appeared to dent any remaining hopes that Kim Jong-un, believed to be 30 years old, would pursue a different path from his father, Kim Jong-il, who oversaw the country's military and nuclear programs.

The older Kim died in December 2011.

"The UNSC (Security Council) resolution masterminded by the U.S. has brought its hostile policy towards the Democratic Peoples Republic of Korea (North Korea) to its most dangerous stage," the commission was quoted as saying.

Seau's family sues NFL over brain injuries

The family of Junior Seau has sued the NFL, claiming the former linebacker's suicide was the result of brain disease caused by violent hits he sustained while playing football.

The wrongful death lawsuit, filed Wednesday in California Superior Court in San Diego, blames the NFL for its "acts or omissions" that hid the dangers of repetitive blows to the head. It says Seau developed chronic traumatic encephalopathy (CTE) from those hits, and accuses the NFL of deliberately ignoring and concealing evidence of the risks associated with traumatic brain injuries.

Seau died at age 43 of a self-inflicted gunshot in May. He was diagnosed with CTE, based on posthumous tests, earlier this month.

An Associated Press review in November found that more than 3,800 players have sued the NFL over head injuries in at least 175 cases as the concussion issue has gained attention in recent years. More than 100 of the concussion lawsuits have been brought together before U.S. District Judge Anita B. Brody in Philadelphia.

"Our attorneys will review it and respond to the claims appropriately through the court," the NFL said in a statement Wednesday.

Helmet manufacturer Riddell Inc., also is being sued by the Seaus, who say Riddell was "negligent in their design, testing, assembly, manufacture, marketing, and engineering of the helmets" used by NFL players. The suit says the helmets were unreasonably dangerous and unsafe.

Seau was one of the best linebackers during his 20 seasons in the NFL. He retired in 2009.

"We were saddened to learn that Junior, a loving father and teammate, suffered from CTE," the family said in a statement released to the AP. "While Junior always expected to have aches and pains from his playing days, none of us ever fathomed that he would suffer a debilitating brain disease that would cause him to leave us too soon.

"We know this lawsuit will not bring back Junior. But it will send a message that the NFL needs to care for its former players, acknowledge its decades of deception on the issue of head injuries and player safety, and make the game safer for future generations."

Plaintiffs are listed as Gina Seau, Junior's ex-wife; Junior's children Tyler, Sydney, Jake and Hunter, and Bette Hoffman, trustee of Seau's estate.

The lawsuit accuses the league of glorifying the violence in pro football, and creating the impression that delivering big hits "is a badge of courage which does not seriously threaten one's health."

It singles out NFL Films and some of its videos for promoting the brutality of the game.

"In 1993's 'NFL Rocks,' Junior Seau offered his opinion on the measure of a punishing hit: 'If I can feel some dizziness, I know that guy is feeling double (that)," the suit says.

The NFL consistently has denied allegations similar to those in the lawsuit.

"The NFL, both directly and in partnership with the NIH, Centers for Disease Control and other leading organizations, is committed to supporting a wide range of independent medical and scientific research that will both address CTE and promote the long-term health and safety of athletes at all levels," the league told the AP after it was revealed Seau had CTE.

The lawsuit claims money was behind the NFL's actions.

"The NFL knew or suspected that any rule changes that sought to recognize that link (to brain disease) and the health risk to NFL players would impose an economic cost that would significantly and adversely change the profit margins enjoyed by the NFL and its teams," the Seaus said in the suit.

The National Institutes of Health, based in Bethesda, Md., studied three unidentified brains, one of which was Seau's, and said the findings on Seau were similar to autopsies of people "with exposure to repetitive head injuries."

"It was important to us to get to the bottom of this, the truth," Gina Seau told the AP then. "And now that it has been conclusively determined from every expert that he had obviously had CTE, we just hope it is taken more seriously. You can't deny it exists, and it is hard to deny there is a link between head trauma and CTE. There's such strong evidence correlating head trauma and collisions and CTE."

In the final years of his life, Seau went through wild behavior swings, according to Gina and to 23-year-old son, Tyler. There also were signs of irrationality, forgetfulness, insomnia and depression.

"He emotionally detached himself and would kind of 'go away' for a little bit," Tyler Seau said. "And then the depression and things like that. It started to progressively get worse."

NASA Telescope Reveals ‘Magnetic Braids’ in Sun’s Atmosphere

A small NASA space telescope has revealed surprising magnetic braids of super-hot matter in the sun’s outer atmosphere, a find that may explain the star’s mysteriously hot corona, researchers say.

The discovery, made by NASA’s High-Resolution Coronal Imager, or Hi-C, also may lead to better space weather forecasts, the scientists added.

“With potential annual economic impacts of tens to hundreds of billions of dollars domestically during periods of high solar activity, accurate forecasts of the local space weather environment can possibly save billions for power systems, commercial aircraft and a number of other economic sectors,” said study author Jonathan Cirtain, who led the Hi-C sun corona mission.

Cirtain,a solar astrophysicist at NASA’s Marshall Space Flight Center, Huntsville, Ala.,and his team launched the 9.5-inch(24 centimeters) telescope last July on a 10-minute flight just beyond Earth’s atmosphere to study the corona, the sun’s million-degree outer atmosphere. The telescope snapped 165 photos in stunning detail before parachuting back to Earth. [NASA's Hi-C Photos: Best View Ever of Sun's Corona]

The sun’s corona revealed

The surface of the sun is unsurprisingly hot, up to 11,000 degrees Fahrenheit (6,125 degrees Celsius). Bizarrely, however, the corona — the outer atmosphere far above the sun’s surface — is hotter by a thousandfold, even in the absence of solar flares.

Scientists recently found that powerful magnetic waves rippling from below the sun’s surface may heat the corona by 2.7 million degrees F (1.5 million degrees C). However, that alone would not account for the corona’s ultra-hot temperatures.

Now high-resolution images of the sun’s corona support the idea of magnetic braids generating tremendous amounts of heat, possibly enough to explain the readings of up to 10.8 million degrees F (6 million degrees C).

To picture these magnetic structures on the sun, “imagine a French braid in someone’s hair,” Cirtain told SPACE.com. “Bundles of individual hairs are wrapped about other bundles and together form a braided ensemble of hair.

“What we have observed is a bundle of magnetic fields, wrapped about several other bundles to form a magnetic bundle ensemble. The magnetic fields in this ensemble have varying lengths, and the rate of curvature along individual field lines may also vary such that some fields are very highly curved while others are less so.” [Sun Quiz: How Well Do You Know Our Star?]

These magnetic fields are physically manifested within the super-hot plasma making up the sun. For instance, very highly curved magnetic fields can take the form of coronal loops, giant arches rising from the sun.

“When a magnetic field becomes highly curved, it eventually becomes unstable,” Cirtain said. Eventually these magnetic braids can grow unstable enough for individual magnetic field lines of force to interact within them. This phenomenon, known as reconnection, decreases the curvature of the magnetic field, releasing potentially vast amounts of energy that can heat plasma or accelerate solar flares and other massive outbursts.

Small telescope that could

While astronomers have seen magnetic braids on the surface of the sun, until now they had little way to see how common the braids were in the corona. To glimpse the magnetic braids, the NASA team launched the Hi-C telescope on a sounding rocket in July. It captured images of the corona with a resolution about five times higher than previously achieved.

The low-budget mission was filled with uncertainties. For instance, the mirror used in the telescope is so smooth that, across its 9.5-inch width, it deviates from perfect smoothness by only a few widths of an atom. There was every chance that mechanical stresses, temperatures changes and other factors before and during the mission could warp its surface, reducing its quality.

“We would only know if it worked once we had flown and taken the images of the sun,” Cirtain said. “This lack of control of the situation kept me up many nights.”

The telescope captured only five minutes of video data before re-entering Earth’s atmosphere. Still, that was enough to discover magnetic braids in the corona, and the amount of activity seen suggested vast amounts of energy can be released there.

The researchers, who detail their findings in the Jan. 24 issue of the journal Nature,  conceded it is possible the braids they saw were not bundles of magnetic fields but sets of many nested magnetic loops overlying and underlying each other. If so, they would store less energy than estimated. Even so, however, the corona would still hold 100 times the energy needed to be super-heated.

“My life for the better part of a decade went into this instrument, and seeing it work was exciting not only for me but for my family and for my close colleagues,” Cirtain said.

The researchers hope to launch their telescope in an orbital satellite to observe the corona longer.

2013 could be 'climate game-changer'

An ice sculpture entitled 'Minimum Monument' by Brazilian artist Nele Azevedo outside Berlin's Concert Hall, September 2, 2009.

STORY HIGHLIGHTS

• The "neglected" risk of climate change seems to be rising to the top of leaders' agendas


• Extreme weather events are costing the global economy billions of dollars each year


• Gas can be an important bridge to a lower carbon future but it's not the answer


• More investment in renewable energy is needed, with fewer risks

Editor's note: Andrew Steer is President and CEO of the World Resources Institute, a think tank that works with governments, businesses and civil society to find sustainable solutions to environmental and development challenges.

(CNN) -- As leaders gather for the World Economic Forum in Davos, signs of economic hope are upon us. The global economy is on the mend. Worldwide, the middle class is expanding by an estimated 100 million per year. And the quality of life for millions in Asia and Africa is growing at an unprecedented pace.

Threats abound, of course. One neglected risk -- climate change -- appears to at last be rising to the top of agendas in business and political circles. When the World Economic Forum recently asked 1,000 leaders from industry, government, academia, and civil society to rank risks over the coming decade for the Global Risks 2013 report, climate change was in the top three. And in his second inaugural address, President Obama identified climate change as a major priority for his Administration.

Andrew Steer

For good reason: last year was the hottest year on record for the continental United States, and records for extreme weather events were broken around the world. We are seeing more droughts, wildfires, and rising seas. The current U.S. drought will wipe out approximately 1% of the U.S. GDP and is on course to be the costliest natural disaster in U.S. history. Damage from Hurricane Sandy will cost another 0.5% of GDP. And a recent study found that the cost of climate change is about $1.2 trillion per year globally, or 1.6% of global GDP.

Shifting to low-carbon energy sources is critical to mitigating climate change's impacts. Today's global energy mix is changing rapidly, but is it heading in the right direction?

Coal is the greatest driver of carbon dioxide emissions from energy, accounting for more than 40% of the total worldwide. Although coal demand is falling in the United States -- with 55 coal-powered plants closed in the past year -- it's growing globally. The World Resources Institute (WRI) recently identified 1,200 proposed new coal plants around the world. And last year, the United States hit a record-high level of coal exports—arguably transferring U.S. emissions abroad.

Meanwhile, shale gas is booming. Production in the United States has increased nearly tenfold since 2005, and China, India, Argentina, and many others have huge potential reserves. This development can be an economic blessing in many regions, and, because carbon emissions of shale gas are roughly half those of coal, it can help us get onto a lower carbon growth path.

However, while gas is an important bridge to a low carbon future—and can be a component of such a future—it can't get us fully to where we need to be. Greenhouse gas emissions in industrial countries need to fall by 80-90% by 2050 to prevent climate change's most disastrous impacts. And there is evidence that gas is crowding out renewables.

Renewable energy -- especially solar and wind power -- are clear winners when it comes to reducing emissions. Unfortunately, despite falling prices, the financial markets remain largely risk-averse. Many investors are less willing to finance renewable power. As a result of this mindset, along with policy uncertainty and the proliferation of low-cost gas, renewable energy investment dropped 11%, to $268 billion, last year.

What do we need to get on track?

Incentivizing renewable energy investment

Currently, more than 100 countries have renewable energy targets, more than 40 developing nations have introduced feed-in tariffs, and countries from Saudi Arabia to South Africa are making big bets on renewables as a growth market. Many countries are also exploring carbon-trading markets, including the EU, South Korea, and Australia. This year, China launched pilot trading projects in five cities and two provinces, with a goal of a national program by 2015.

Removing market barriers

Despite growing demand for renewable energy from many companies, this demand often remains unmet due to numerous regulatory, financial, and psychological barriers in the marketplace.

In an effort to address these, WRI just launched the Green Power Market Development Group in India, bringing together industry, government, and NGOs to build critical support for renewable energy markets. A dozen major companies from a variety of sectors—like Infosys, ACC, Cognizant, IBM, WIPRO, and others— have joined the initiative. This type of government-industry-utility partnership, built upon highly successful models elsewhere, can spur expanded clean energy development. It will be highlighted in Davos this week at meetings of the Green Growth Action Alliance (G2A2).

De-risking investments

For technical, policy, and financial reasons, risks are often higher for renewables than fossil-based energy. Addressing these risks is the big remaining task to bring about the needed energy transformation. Some new funding mechanisms are emerging that can help reduce risk and thus leverage large sums of financing. For example, the Green Climate Fund could, if well-designed, be an important venue to raise funds and drive additional investments from capital markets. Likewise, multi-lateral development banks' recent $175 billion commitment to sustainable transport could help leverage more funds from the private and public sectors.

Some forward-looking companies are seeking to create internal incentives for green investments. For example, companies like Unilever, Johnson & Johnson, and UPS have been taking actions to reduce internal hurdle rates and shift strategic thinking to the longer-term horizons that many green strategies need.

Davos is exactly the type of venue for finding solutions to such issues, which requires leadership and coalition-building from the private and public sectors. For example, the the G2A2, an alliance of CEOs committed to addressing climate and environmental risks, will launch the Green Investment Report with precisely the goal of "unlocking finance for green growth".

Depending on what happens at Davos—and other forums and meetings like it throughout the year—2013 could just be a game-changer.

2 men died in high-rise fire after rescuing elderly woman: officials

A high-rise fire on Chicago's south side killed two men and seriously injured a woman.

The two men who died in a South Shore high-rise fire had rescued an elderly woman on the seventh floor and had returned to the burning apartment with fire extinguishers when they apparently were overcome by smoke, officials said today.

Jameel Johnson, 36, and John Fasula, 50, were working in the 16-story building in the 6700 block of South Shore Drive Tuesday morning when the fire broke out on the seventh floor, officials said.

The two heard an 81-year-old woman screaming for help and placed her inside an elevator and pressed a button to take her to the first floor, according to police and David A. Fields Jr., Johnson’s cousin.

Fasula and Johnson returned to her apartment with fire extinguishers, police said. They were later found by firefighters, collapsed on the floor and were in full cardiac arrest, according to police and fire officials.

The woman collapsed on the floor of the lobby after the elevator doors opened, but was revived by paramedics and taken to the University of Chicago Hospitals, where she was listed in critical condition from smoke inhalation, according to police.

“He died a hero,” Fields said in a telephone interview. “They died saving a woman’s life.”

Johnson, the father of two girls, was working as a private contractor for a cable company, his family said. He did not like being inside high-rise buildings, but the company could not find a replacement, relatives said.

“He went with the understanding that maybe it was just a service call and he could be in and out,” Fields said. “He didn’t want to be in the high-rise building, that was his whole thing. He didn’t want to be there.”

Relatives described Johnson, an Englewood native, as a fun-loving man who did whatever he could to take care of his fiance and two children, ages 14 and 3. Johnson had ventured into different careers over the years, but returned to the cable business about a year ago.

“He was a good father who was just trying to make sure his kids had the best,” Fields said.

He had been with his fiance for 15 years and the family lives in Gary, Ind., Fields said. His youngest daughter still doesn’t understand what happened, relatives said.

“She’s still looking for her father to come home,” said Johnson’s aunt, Rosemary Cohns. “That’s the hardest part.”

Relatives of Fasula said they were not surprised to hear he risked his life for someone else.

“That’s how my brother-in-law was,” said Michelle Kozicki, 65, Fasula’s sister-in-law. “There’s never going to be another one like my brother-in-law Johnny. There’s not a bad bone in his body.”

Fasula was a maintenance manager for the CTA, spokeswoman Lambrini Lukidis said. He started working for the transit agency in 1983.

Fasula’s family knew he was at the apartment building for a “side job,” though she wasn’t sure what the work entailed. Kozicki said it was common for Fasula, who had been married for nearly 40 years, to work jobs outside his day job at the CTA.
 
“He didn’t like to sit still,” she said.

He went out of his way to help his father before he died in 2009. He was with him “every step of the way,” Kozicki said. For example, Fasula took time off of work to drive his father to doctor’s appointments.

Cook County Commissioner John Daley, who knew Fasula through his father, called him an "outstanding young man" whose death is a "tremendous loss."

"If you were in trouble, John was always there," Daley said.

Fire officials have said the fire apparently started in a bedroom on the seventh floor. Fire Department spokesman Larry Langford said the cause is undetermined pending further analysis of electrical information.  It does not appear suspicious, he added.

“In short, it generally means we have to have some items looked at,” Langford said of the analysis.
