NCAA announces problems with Miami investigation

CORAL GABLES, Fla. (AP) — The NCAA's probe of Miami's athletic compliance practices is ramping up again.

Only this time, the Hurricanes aren't exactly the subject of the inquiry.

In a bizarre twist, the college sports' governing body is being investigated after NCAA President Mark Emmert acknowledged on Wednesday "a very severe issue of improper conduct" by former investigators working the long, complex Miami case.

The NCAA said its investigation was based, at least in part, on information that it should not have had access to, the testimony of those who appeared under subpoena to be deposed in the bankruptcy case involving former Miami booster Nevin Shapiro, one of the most notorious Ponzi scheme architects in history.

The NCAA does not have subpoena power. Shapiro's attorney did, and used it — and apparently entered into some sort of contractual agreement with the NCAA, one that apparently either was not or should never have been approved.

"We cannot have the NCAA bringing forward an allegation ... that was collected by processes none of us could stand for," Emmert said. "We're going to move it as fast as possible, but we have to get this right."

Speaking Thursday from Providence, R.I. in a telephone interview, Shapiro's attorney, Maria Elena Perez, told The Associated Press that she has done nothing wrong.

"The dubious party is not me. What I have done is 150 percent above board," Perez said.

Perez said she could not divulge the nature of whatever her contract status with the NCAA, though said she is planning to release a statement in the coming days after meeting with her own attorney.

"I am a victim of the enforcement staff," said Perez, who is a Miami graduate. "Me."

The revelations Wednesday mean the notice of allegations against Miami — the NCAA's findings of wrongdoing, a document that was nearly completed and was expected to be released by the end of this week — will be delayed for at least a few more weeks, if not longer. The long-term ramifications could be more damning for the NCAA, especially if the outside investigator they have commissioned to look into the mess finds more problems.

"As we have done since the beginning, we will continue to work with the NCAA and now with their outside investigator hoping for a swift resolution of the investigation and our case," Miami President Donna Shalala said.

Emmert said two depositions are involved in this allegation of improper conduct by former enforcement-office staffers. One of those two depositions was given Dec. 19, 2011, by former Miami equipment-room staffer Sean Allen — who has been linked to Shapiro and many of the allegations that he made against the university.

Among the questions Allen was asked in that deposition:

— "Did you ever witness Mr. Shapiro paying any money to any University of Miami football or basketball players?"

— "Would it be fair to say that Mr. Shapiro did, in fact, confer various financial benefits on the University of Miami Athletic Program and its players?"

— "Did you ever overhear any of the coaches or any other staff for the University of Miami providing Mr. Shapiro with inside information regarding, you know, the condition of any particular athlete for the purposes of Mr. Shapiro's gambling?"

It's unknown which of Allen's answers caught the NCAA investigators' attention.

What is known publicly now, and has been suspected by some for months, is that those investigators never should have known those questions were asked.

"How in the world can you get this far without it being recognized that this was an inappropriate way to proceed?" Emmert asked.

That's the question that the NCAA wants answered, and fast.

Emmert spoke angrily at times during a half-hour conference call to discuss the findings, in which he revealed that he briefed the NCAA's executive committee and the Division I board presidents with some information about the Miami matter. He said he developed a better understanding of what went on in the days that followed, which led to the hiring of Kenneth L. Wainstein of the firm Cadwalader, Wickersham & Taft LLP to conduct the external review of what happened.

Wainstein, Emmert said, will begin his probe on Thursday, with the NCAA hoping that he can finish within two weeks.

"We want to make sure that any evidence that's brought forward is appropriately collected and it has the integrity that we expect and demand," Emmert said.

It was part of a stunning day for Hurricane athletics: The 25th-ranked men's basketball team routed No. 1 Duke later Wednesday, 90-63.

Emmert said the NCAA was trying to find out why part of the investigation was based on depositions specific to the bankruptcy case against Shapiro, who will have to repay $82.7 million to his victims as part of his sentence. And the timing of this also is curious. Several people who were to be named in the NCAA's notice of allegations against Miami have been told that the document was in the final stages of preparation — and one person who spoke with the AP said at least one person who was to face a charge of wrongdoing was told the letter was scheduled for delivery to Miami on Tuesday.

Now it's anyone's guess when that will happen.

Emmert said the NCAA learned of the alleged misconduct, in part, through legal bills presented by Shapiro's attorney for work that was not properly approved by the organization's general counsel's office.

"One of the questions that has to be answered, unequivocally, is what was the nature of that contractual arrangement and what was all the activity that that individual was involved with," Emmert said. "There is some uncertainty about all of that and it's one of the first orders of business for the firm that we've hired to investigate."

The Hurricanes' athletic compliance practices have been probed by the NCAA for nearly two years. Allegations of wrongdoing involving Miami's football and men's basketball programs became widely known in August 2011 when Yahoo Sports published accusations brought by Shapiro, who is serving a 20-year term in federal prison for masterminding a $930 million Ponzi scheme.

Miami has self-imposed two football postseason bans in response to the investigation. The Hurricanes also would have played in the Atlantic Coast Conference championship game this past season, meaning they could have qualified for the Orange Bowl.

"In my two-and-a-half years I've certainly never seen anything like this, and don't want to see it again," Emmert said.

Obama’s Climate Vow Could Make EPA a Political Target

President Obama’s second Inaugural Address left no doubt about his desire to put climate change front and center in his second term. He’s likely to pursue his agenda through executive actions rather than legislation, at least initially.

That could put the Environmental Protection Agency at the center of a political battle, as Senate Republicans use the process of confirming a new head of the agency as a chance to weigh in on or even block what they see as regulatory overreach by the administration in pursuit of climate-change goals.

Republicans have bristled in the last four years at regulations coming out of Obama‘s EPA–Rep. Michele Bachmann of Minnesota wanted to shut the agency altogether. Administrator Lisa Jackson was a particular target, criticized for her implementation of Clean Air Act regulations and, more recently, for conducting official business using an email alias. 

As Obama‘s second term begins, EPA might become an even bigger target as Republicans brace for the likelihood that Obama will use the agency’s powers to pursue his climate agenda. Environmental groups have urged the administration to use EPA’s authority under the Clean Air Act to limit the carbon emissions power plants are allowed to produce and to implement stricter standards on leaks of methane, a greenhouse gas, both of which can be achieved without any further congressional approval.

Although EPA is the prime symbol of the Obama administration’s climate-change agenda, other agencies will also play a role—agencies that are expected to face confirmation fights in the coming months. The Energy Department, for example, can adopt new efficiency standards for home appliances. The State Department will rule on a permit for part of the Keystone XL pipeline that would cross into Canada. Each of those agencies is likely to face or already in the process of confirming a new director, and questions over their views on climate could be part of the confirmation hearings. At EPA, Jackson announced she was stepping down last month, and the administration has yet to nominate a replacement.

Congress isn’t expected to take up climate legislation any time soon. It will be preoccupied in coming months by a series of looming budget fights, gun-control legislation, and immigration reform. A sweeping cap-and-trade bill that Obama had pushed in his first term never made it through Congress. This time, Senate Democrats have indicated they are ready to let the EPA run the show.

So get ready for a show. 

Melinda Pierce, deputy director for national campaigns at the Sierra Club, said the hearing to replace Jackson at EPA might be “doubly contentious” if the agency is perceived as a key stakeholder in moving Obama‘s climate agenda forward. 

The focus on climate in Monday’s inaugural speech surprised—and pleased—environmental groups. But it could also set up a tougher hearing, said Andrew Wheeler, a former Republican staff director and chief counsel for the Senate Environment and Public Works Committee.

“During the campaign, President Obama tried to appeal to the coal states. He never once mentioned climate change. He tried at one point to even go to the right of Mitt Romney on coal issues. He didn’t mention climate change until the night of the election after he won. In his acceptance speech, he mentioned climate change and then he mentioned it again this week…. I think that’s going to generate a lot of questions and concerns from members, not just Republicans, but also moderate Democrats,” Wheeler said. Especially vulnerable are the six Democratic senators from red states who will face tough reelection battles in 2014.

What’s more, Wheeler said, now that Obama is in his second term, there won’t be the typical deference given to a new president’s Cabinet selections.

Confirmation hearings are a good place for the minority to be heard on administration goals. “You’ll get good press out of it and, quite frankly, you might not have the administrator come back up to the Hill until the following year,” said David Banks, a former deputy staff director for Republicans on the Senate Environment and Public Works Committee.

But even if the EPA confirmation fight is nasty, it probably would not deter Obama from implementing his second-term climate agenda. Under the Clean Air Act, the EPA has a legal duty to issue regulations limiting power-plant carbon emissions, said Conrad Schneider, advocacy director at the Clean Air Task Force, which recently sent an open letter to Obama outlining its recommendations for addressing climate change over the next four years. CATF also believes that the EPA failed to do its duty with respect to regulating emissions of methane from the oil and gas industry during Obama’s first term. “Since those are statutory duties, it really doesn’t matter who is at the head of the agency. Those duties exist if the nominee is confirmed quickly and those duties exist if the nominee’s confirmation process drags out,” he said.

So consider the confirmation hearings a preview of the bigger fight on climate change in Congress over the next four years. Republicans may try to block the new regulations. Obama may try to get another climate bill through Congress. Legislation, environmental groups say, is the best way for Obama to secure the climate-change legacy he wants in the long run.

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.

Massive warehouse fire rekindles

A fire at a warehouse at 37th and Ashland has rekindled in the Bridgeport neighborhood.

Fire has rekindled at a Bridgeport warehouse that was gutted by a massive extra-alarm blaze earlier this week.

Fire officials had expected the fire to start up again because of the magnitude of Tuesday night's 5-11 alarm fire and the old timber in the warehouse, according to Chicago Fire Department spokeswoman Meg Ahlheim.

"We expected it. We have companies working there again," she said this morning. "We were working there well into yesterday."

A still-and-box alarm, standard for working fires, was called this morning and a rapid intervention team was on the scene in case any firefighters are hurt.
 
“No one’s going in,” Ahlheim said. “We do have (a team) at every working fire.”

The Fire Department also deployed a piece of equipment from the 1960s dubbed "Big Mo" that can shoot 2,000 to 3,000 gallons of water a minute from two turrets fed by 10 water lines.

Firefighters had expected the fire to rekindle in areas where the roof and floors had collapsed, Ahlheim said.  “There are hot spots under those collapses we haven’t been able to reach. When debris gets moved, there’s more oxygen for the fire to grow,” she said. “Then we get to those hot spots.”

“This is something we had expected and had seen before,” she said.

The fire originally broke out at the former Harris Marcus Group building at 3757 S. Ashland Ave. Tuesday evening. Extra alarms were quickly called as the fire spread throughout the warehouse and the roof collapsed and the more than 200 firefighters contended with frozen hydrants and icy ladders.

Chicago Fire Cmsr. Jose Santiago said the fire was Chicago's largest in seven years. "This was a very large fire, unbelievable fire load, a lot of wood, timber, old stuff, varnish," Santiago said on the scene. "Once it caught, it caught and ran.

"Everything is wood inside these buildings, beautiful façades on the outside. They've been up for a long time. When they start burning like this, they start coming down," Santiago said.

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.

IBM's outlook lifts Dow, Nasdaq amid tech rally

NEW YORK (Reuters) - Stocks edged higher on Wednesday as IBM and other tech companies continued a trend of results that beat Wall Street's expectations and propelled the market to a five-day advance.

Internet search company Google Inc added to the advance, rising 5.1 percent to $738.65 a day after Google reported its core business outpaced expectations. Revenue was also higher than expected.

International Business Machines Corp late Tuesday forecast better-than-anticipated 2013 results and also posted fourth-quarter earnings and revenue that beat expectations. The results helped to allay concerns about the tech sector after Intel Corp gave a weak outlook last week. IBM, the world's largest technology services company, rose 3.8 percent to $203.57.

"Tech companies are really shattering expectations, which is obviously helping markets. There doesn't seem to be an end to this rally," said Todd Schoenberger, managing partner at LandColt Capital in New York.

But gains were limited in the S&P 500 a day after it closed at a level not seen since December 2007. Many investors were also holding off to see earnings from Apple Inc , the most valuable U.S. company which was due to report after the market closes.

McDonald's edged higher 0.2 percent to $93.11 after reporting a rise in fourth-quarter earnings, lifted by an increase in same-store sales. United Tech's earnings fell from the prior year, hurt by large restructuring charges. Shares edged up at $87.91.

On the downside, Coach Inc slumped 15 percent to $51.40 as the S&P's biggest percentage loser after reporting sales that missed expectations.

After the market closes, investors will scour Apple's results for signs the tech giant can continue to grow at an accelerated pace. The stock has been pressured recently by questions raised about demand for Apple's prospects. The stock has fallen 5 percent since the start of the year, compared with gains of 4.6 percent in the S&P 500. It rose 0.4 percent to $507.04 on Wednesday.

"If Apple comes out with a blockbuster number, that would reinforce the argument that stocks are poised to do well in the first part of 2013," Schoenberger said.

The Dow Jones industrial average <.dji> was up 55.48 points, or 0.40 percent, at 13,767.69. The Standard & Poor's 500 Index <.spx> was up 0.06 points, or 0.00 percent, at 1,492.62. The Nasdaq Composite Index <.ixic> was up 10.89 points, or 0.35 percent, at 3,154.06.

Both the S&P 500 and Dow Jones industrial average hit five-year closing highs on Tuesday, with recent gains largely fueled by a strong start to the earning season.

According to the latest Thomson Reuters data, of the 74 S&P 500 companies that have reported earnings so far, 62.2 percent have topped expectations, roughly even with the 62 percent average since 1994, but below the 65 percent average over the past four quarters.

Overall, S&P 500 fourth-quarter earnings rose 2.6 percent, according to Thomson Reuters data. That estimate is above the 1.9 percent forecast from the start of earnings season, but well below the 9.9 percent fourth-quarter earnings forecast from October 1, the data showed.

Republican leaders in the U.S. House of Representatives aim on Wednesday to pass a bill to extend the U.S. debt limit by nearly four months, to May 19. The White House welcomed the move, saying it would remove uncertainty about the issue.

The debt limit issue has hung over the market for weeks, with many investors worried that if no deal is reached to raise the limit, it could have a negative impact on the economy.

Williams loses to Stephens; Federer advances

MELBOURNE, Australia (AP) — Serena Williams was only thinking out loud when she muttered this Australian Open had been "the worst two weeks."

Not long after a courtside microphone picked up those comments during her quarterfinal with 19-year-old American Sloane Stephens, things got a whole lot worse.

Stephens outplayed Williams, whose movement and serves had been slowed by a back injury, and beat the 15-time Grand Slam champion 3-6, 7-5, 6-4. It marked Williams' first loss since Aug. 17, and her first defeat at a Grand Slam tournament since last year's French Open.

Four-time Australian Open winner Roger Federer, a 17-time Grand Slam champion, looked for a while like he might join Williams on the sideline. But Federer eked out a 7-6 (4), 4-6, 7-6 (4), 3-6, 6-3 win over 2008 finalist Jo-Wilfried Tsonga in a match that lasted 3 hours, 34 minutes.

Federer, who broke Tsonga in the fourth game of the deciding set, converted his fifth match point while serving after Tsonga saved four match points in the previous game. Federer, who advanced to the semifinals for the 10th consecutive year at Melbourne Park, will play U.S. Open champion Andy Murray on Friday.

"I thought he played very aggressive," Federer said. "I love those four-set or five-set thrillers and I was part of one tonight."

Murray beat Jeremy Chardy of France 6-4, 6-1, 6-2. The other men's semifinal has defending champion Novak Djokovic playing David Ferrer on Thursday

Williams' downer of a Grand Slam Down Under started badly when she turned her right ankle in her opening match at Melbourne Park.

"I've had a tough two weeks between the ankle ... and my back, which started hurting," Williams said. "A lot of stuff."

While Williams packed for home — she and sister Venus have also lost in doubles — Stephens advanced to her first Grand Slam semifinal Wednesday night against defending champion Victoria Azarenka.

The top-seeded Azarenka beat Svetlana Kuznetsova 7-5, 6-1 in the early quarterfinal at Rod Laver Arena. Maria Sharapova, who has lost only nine games in five matches, plays Li Na in the other semifinal.

Williams hurt her back in the eighth game of the second set and things got progressively worse. She yelled at herself on several occasions, and smashed a racket into the court, earning a $1,500 fine from tournament officials.

"I was running to the net for a drop shot," said Williams, describing the injury. "As I went to hit it, it was on the backhand. I even screamed on the court. I totally locked up after that."

She reiterated after the match that her injuries had made this Australian Open difficult for her.

"Absolutely, I'm almost relieved that it's over because there's only so much I felt I could do," she said. "I've been thrown a lot of (curve) balls these two weeks."

Stephens has coped well this week, and the magnitude of her accomplishment only hit her while she was warming down after the match.

"I was stretching, and I was like, 'I'm in the semis of a Grand Slam.' I was like, 'Whoa. It wasn't as hard as I thought,'" she said. "To be in the semis of a Grand Slam is definitely a good accomplishment. A lot of hard work."

The No. 29-seeded Stephens hadn't been given much of a chance of beating Williams, who lost only four matches in 2012 and was in contention to regain the No. 1 ranking at age 31.

Williams' latest winning streak included a straight-set win over Stephens at the Brisbane International this month.

Stephens wasn't even sure that she could beat Williams until she woke up Tuesday.

"When I got up, I was like, 'Look, Dude, like, you can do this.' Like, 'Go out and play and do your best," she said.

Williams walked around the net to congratulate Stephens, who then clapped her hand on her racket and waved to the crowd, a look of disbelief on her face.

Stephens has said she had a photo of Williams in her room when she was a child, and had long admired the Williams sisters.

"This is so crazy. Oh my goodness," Stephens said, wiping away tears in her post-match TV interview. "I think I'll put a poster of myself (up) now."

Azarenka, with her most famous fan Redfoo sitting in the crowd wearing a shirt reminding her to keep calm, overcame some early jitters to beat Kuznetsova.

After dropping serve in a long fourth game that went to deuce 10 times, Azarenka recovered to dominate the rest of the match against Kuznetsova, a two-time major winner who was floating dangerously in the draw with a No. 75 ranking as she recovers from a knee injury.

Azarenka's American rapper friend returned from a concert in Malaysia to attend the quarterfinal match.

Wearing a red sleeveless T-shirt that read "Keep Calm and Bring Out the Bottles," the name of his next single, Redfoo stood, clapped and yelled "Come on, Vika!" during the tight first set.

Williams' loss was a boost for Azarenka, who lost all five head-to-heads against the American in 2012 and is 1-11 in their career meetings.

Tsonga said he was in a "bad mood" because he lost despite playing a good match against Federer.

"I was solid. I was there every time," he said. "I just gave my best today, so I'm proud of that."

The 25-year-old Murray had his service broken for only the second time while serving for the match. But he broke back immediately to clinch a quarterfinal victory.

Murray discounted comments in the British media that he was upset with an almost full schedule of day matches while Federer was given cooler night slots on Rod Laver Arena.

"The scheduling for me is part and parcel of playing in really any tennis tournament," Murray said. "It's tough to make the schedule perfect for every single player."

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

(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.

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.

Pearl Jam will be playing at Wrigley Field Friday, July 19, the band confirmed this morning.

The band tweeted out, "IT'S OFFICIAL: Pearl Jam will be playing at Wrigley Field. Will you be there?" The show will be called “An Evening With Pearl Jam," with no opening act.

Pearl Jam and the Cubs haven't been very subtle about the possibility of the iconic band playing a concert at Wrigley Field in 2013.

Tuesday afternoon, both the Cubs and Pearl Jam Tweeted pictures of the field at Wrigley, with a full concert setup. The band's Tweet, featuring the "stay tuned" hashtag, also included a "looking good" reference to the Wrigley image.

The Cubs also played a role in the suspense, sending out a Tweet that included "Ten," and a repeat of the "stay tuned" hashtag. There was also a link to a photo of a Ron Santo Cubs jersey (No. 10), the parallel being that “Ten” is also the title of Pearl Jam’s first album.

The band also announced a July 16 date in London, Ontario.

Cameron promises Britons straight choice on EU exit

LONDON (Reuters) - Prime Minister David Cameron promised on Wednesday to give Britons a referendum choice on whether to stay in the European Union or leave if he wins an election in 2015, placing a question mark over Britain's membership for years.

Cameron ended months of speculation by announcing in a speech the plan for a vote sometime between 2015 and the end of 2017, shrugging off warnings that this could imperil Britain's economic prospects and alienate its biggest trading partner.

He said the island nation, which joined the EU's precursor European Economic Community 40 years ago, did not want to retreat from the world, but public disillusionment with the EU was at "an all-time high".

"It is time for the British people to have their say. It is time for us to settle this question about Britain and Europe," Cameron said. His Conservative party will campaign for the 2015 election promising to renegotiate Britain's EU membership.

"When we have negotiated that new settlement, we will give the British people a referendum with a very simple in or out choice to stay in the European Union on these new terms; or come out altogether. It will be an in-out referendum."

The speech firmly ties Cameron to an issue that was the bane of a generation of Conservative leaders. In the past, he has avoided partisan fights over Europe, the undoing of the last two Conservative prime ministers, John Major and Margaret Thatcher.

Britain would seek to claw back powers from Brussels, he said, a proposal that will be difficult to sell to other European countries. London will do an "audit" to determine which powers Brussels has that should be delegated to member states.

Sterling fell to its lowest in nearly five months against the dollar on Wednesday as Cameron was speaking.

The response from EU partners was predictably frosty. French Foreign Minister Laurent Fabius quipped: "If Britain wants to leave Europe we will roll out the red carpet for you," echoing Cameron himself, who once used the same words to invite rich Frenchmen alienated by high taxes to move to Britain.

German Foreign Minister Guido Westerwelle said his country wanted Britain to remain a full EU member, but London could not expect to pick and choose the aspects of membership it liked.

Business leaders have warned that the prospect of years of doubt over Britain's EU membership would damage the investment climate.

"Having a referendum creates more uncertainty and we don't need that," Martin Sorrell, chief executive of advertising giant WPP, told the World Economic Forum in Davos.

"This is a political decision. This is not an economic decision. This isn't good news. You added another reason why people will postpone investment decisions."

The speech also opens a rift with Cameron's junior coalition partners, the Liberal Democrats. Their leader, Deputy Prime Minister Nick Clegg, said the plan would undermine a fragile economic recovery.

And even allies further afield are wary: the United States has said it wants Britain to remain inside the EU with "a strong voice".

EUROSCEPTICS THRILLED

Cameron has been pushed into taking such a strong position in part by the rise of the UK Independence Party, which favors complete withdrawal from the EU and has climbed to third in opinion polls, mainly at the expense of the Conservatives.

"All he's trying to do is to kick the can down the road and to try and get UKIP off his back," said UKIP leader Nigel Farage.

Eurosceptics in Cameron's party were thrilled by the speech. Conservative lawmaker Peter Bone called it "a terrific victory" that would unify 98 percent of the party. "He's the first prime minister to say he wants to bring back powers from Brussels," Bone told Reuters. "It's pretty powerful stuff".

Whether Cameron will ever hold the referendum remains as uncertain as the Conservatives' chances of winning the next election in 2015.

They trail the opposition Labour party in opinion polls, and the coalition government is grappling with a stagnating economy as it pushes through public spending cuts to reduce Britain's large budget deficit.

Cameron said he would prefer Britain, the world's sixth biggest economy, to remain inside the 27-nation EU. As long as he secured the reforms he wants, he would campaign for Britain to stay inside the EU "with all my heart and soul".

But he also made clear he believed the EU must be radically reformed. It was riskier to maintain the status quo than to change, he said.

"The biggest danger to the European Union comes not from those who advocate change, but from those who denounce new thinking as heresy," he said.

"WAFER THIN" CONSENT

The euro zone debt crisis was forcing the bloc to change, and Britain would fight to make sure new rules were fair to countries that didn't use the common currency, he said. Britain is the largest of the 10 EU members that do not use the euro.

Democratic consent for the EU in Britain was now "wafer thin", he said, reflecting the results of opinion polls that show a slim majority would vote to leave the bloc.

"Some people say that to point this out is irresponsible, creates uncertainty for business and puts a question mark over Britain's place in the European Union," said Cameron. "But the question mark is already there: ignoring it won't make it go away."

Asked after the speech whether other EU countries would agree to renegotiate Britain's membership, Cameron said he was an optimist and that there was "every chance of success."

"I want to be the prime minister who confronts and gets the right answer for Britain on these kind of issues," he said.

It is nearly 40 years since British voters last had a say in a referendum on Britain's membership of the European club. A 1975 vote saw just over 67 percent opt to stay inside with nearly 33 percent wanting to leave.
