Energy-Guzzling Cities Changing Weather 1,000 Miles Away

The heat released by everyday activities in energy-guzzling cities is changing the weather in far-away places, scientists report today (Jan. 27).

The released heat is changing temperatures in areas more than 1,000 miles away (1609 kilometers). It is warming parts of North America by about 1 degree Fahrenheit (0.6 degrees Celsius) and northern Asia by as much as 1.8 degrees Fahrenheit (1 degree Celsius), while cooling areas of Europe by a similar amount, scientists report in the journal Nature Climate Change.

The released heat (dubbed waste heat), it seems, is changing atmospheric circulation, including jet streams — powerful narrow currents of wind that blow from west to east and north to south in the upper atmosphere. 

This impact on regional temperatures may explain a climate puzzle of sorts: why some areas are having warmer winters than predicted by climate models, the researchers said. In turn, the results suggest this phenomenon should be accounted for in models forecasting global warming.

“There’s a tendency in climate science to overlook the effects of cities,” Brian Stone, a professor of city and regional planning at Georgia Tech, told LiveScience. “Cities occupy just a few percent of the global land surface, but the amount of energy released as waste heat is contributing downwind to pretty significant changes in climate. I hope this will encourage us to focus more on cities as important drivers of climate change,” added Stone, who was not involved in the current study. [8 Ways Global Warming Is Already Changing the World]

Hot in the city

Cities are known to be warmer than their surroundings due to what’s known as the urban heat island effect — pavement, buildings and other building materials retain heat, preventing it from reradiating into the sky.

In the new study, the researchers looked at another kind of “urban heat,” this one produced directly by transportation, heating and cooling units, and other energy-consuming activities.

“The burning of fossil fuel not only emits greenhouse gases, but also directly affects temperatures because of heat that escapes from sources like buildings and cars,” said study researcher Aixue Hu, of the National Center for Atmospheric Research (NCAR), in a statement. “Although much of this waste heat is concentrated in large cities, it can change atmospheric patterns in a way that raises or lowers temperatures across considerable distances.”

Hu and colleagues studied the energy effect using the National Center for Atmospheric Research (NCAR) model, a widely used climate model that takes into account the effects of greenhouse gases, topography, oceans, ice and global weather. The researchers ran the model with and without the input of human energy consumption, to see whether it could account for large-scale regional warming.

When man-made energy was included in the model, it led to winter and autumn temperature changes of up to 1.8 degrees F (1 degree C) in mid- and high-latitude parts of North America and Eurasia. The modeling is based on estimates, however, and more studies are needed to measure how much heat is actually released by urban areas.

Heat disrupts jet stream

Here’s how the scientists think it works: Energy-hungry metropolitan areas are located on the east and west coasts of North America and Eurasia, beneath major “hot spots” of atmospheric circulation. The waste heat from these cities creates thermal mountains, or taller-than-normal columns of heated air, which cause air jets moving eastward to deflect northward and southward.

As a result, the jet stream in upper latitudes widens and strengthens, bringing up hot air from the south and causing warming far from the urban areas (and concurrent cooling in others).

“The energy consumption in highly populated areas can cause changes in wind patterns, and that causes climate change far away from the heating source,” said meteorologist and study author Ming Cai of Florida State University.

Why haven't we learned from fires?

STORY HIGHLIGHTS

• Pyrotechnics, overcrowding, poor exits have contributed to tragic fires in recent years


• You would think the world would have learned from past incidents, John Barylick says


• Concertgoers have to be their own fire marshals, he says

Editor's note: John Barylick, author of "Killer Show," a book on the 2003 Station nightclub fire in Rhode Island, is an attorney who represented victims in wrongful death and personal injury cases arising from the fire.

(CNN) -- Sunday morning we awoke to breaking news of another tragic nightclub fire, this time in Brazil. At last report the death toll exceeded 230.

This tragedy is not without precedent. Next month will mark the 10th anniversary of a similar nightclub fire in Rhode Island. At this sad time, it's appropriate to reflect on what we've learned from club fires -- and what we haven't.

Rhode Island's Station nightclub fire of 2003, in which 100 concertgoers lost their lives, began when fireworks set off by Great White, an 80s heavy metal band, ignited flammable packing foam on the club's walls.

John Barylick

Panicked patrons stampeded toward the club's main exit, and a fatal pileup ensued. Contributing to the tragedy were illegal use of pyrotechnics, overcrowding and a wall covering that would have failed even the most rudimentary flammability tests.

Video images of the Station fire were broadcast worldwide: A concert begins; the crowd's mood changes from merry, to curious, to concerned, to horrified -- in less than a minute. You'd think the world would have learned from it. You would be wrong.

Deadly blazes: Nightclub tragedies in recent history

The following year, the Republica Cromanon nightclub in Argentina went up in flames, killing 194 people. The club was made to hold about 1,000 people, but it was estimated that more than 3,000 fans were packed inside the night of the fire, which began when fans began lighting flares that caught the roof on fire.

Then, in January 2009, at least 64 New Year's revelers lost their lives in a nightclub in Bangkok, Thailand, after fire ignited its ceiling. Many were crushed in a rush to get out of the club. In December of that same year, a fire in a Russian nightclub, ignited by pyrotechnics, killed 156 people. Overcrowding, poor exits, and indoor fireworks all played roles in these tragedies; yet no one bothered to learn from mistakes of the past.

While responsibility for concert disasters unquestionably lies with venue operators, performers and promoters, ultimately, we, as patrons of clubs and concerts, can enhance our own safety by taking a few simple steps. The National Fire Protection Association urges concertgoers to:

• Be observant. Is the concert venue rundown or well-maintained? Does the staff look well-trained?

• As you proceed to your seat, observe how long the process takes. Could you reverse it in a hurry? Do you pass through pinch points? Is furniture in the way?

• Once seated, take note of the nearest exit. (In an emergency, most people try to exit by the door they entered, which is usually not the closest, and is always overcrowded.) Then, share the location of that nearest exit with your entire party. Agree that at the first sign of trouble, you will all proceed to it without delay.

• Once the show begins, remain vigilant. If you think there's a problem, LEAVE IMMEDIATELY. Do not stay to "get your money's worth" despite concerns about safety. Do not remain to locate that jacket or bag you placed somewhere. No concert is worth your life. Better to read about an incident the next day than be counted as one of its statistics.

Read more: How to protect yourself in a crowd

To be sure, all fire codes must be vigorously enforced, and club and concert hall operators must be held to the highest standards. A first step is banning indoor pyrotechnics in all but the largest, stadium-type venues.

But, ultimately, we are our own best "fire marshals" when it comes to avoiding, and escaping, dangerous situations. We can still enjoy shows. But it is up to us to look out for our own safety.

In coming days, Rhode Islanders will follow the unfolding news from Brazil with a sense of queasy deja vu -- the rising body counts, the victim identification process, the grieving families, and the assigning (and dodging) of blame. If only they had learned from our tragedy.

2 dead after apparent carbon monoxide leak in W. Rogers Park

Two women are dead and another was hospitalized after an apparent carbon monoxide leak in a West Rogers Park building, officials said.

Paramedics were first called about 10:30 a.m. to the building, which is in the 2500 block of West North Shore Avenue, to transport one woman to the hospital, Chicago Fire Department spokeswoman Meg Ahlheim said.

The woman was taken in cardiac arrest to Swedish Covenant Hospital, Ahlheim said.

Fire officials at the scene called for a second ambulance, and a second woman was taken to Swedish Covenant as well, Ahlheim said.

Once paramedics became aware of the second victim, fire officials checked the building's carbon monoxide levels but found no indication of a leak, Ahlheim said.

Paramedics were called back to the scene, however, about 3:45 p.m., for another woman found unresponsive. The woman was taken to St. Francis Hospital in Evanston in critical condition, Ahlheim said.

Officials checked carbon monoxide level again, and while the meter readings in residential units showed no exposure, officials found a positive reading for a low level of carbon monoxide near a boiler in the basement, Ahlheim said.

The Cook County medical examiner's office confirmed Sunday evening that it had been notified of two fatalities from the building.

Police suspect the deaths were caused by accidental carbon monoxide poisoning, but no official determination will be made until autopsy results are reported, Chicago Police Department News Affairs Officer Amina Greer said.

A spokeswoman for Peoples Gas, Jennifer Block, confirmed that representatives from the company were called to the building to assist police and fire officials. She referred further questions to the police and fire departments.

Egypt's Mursi declares emergency after clashes kill dozens

CAIRO (Reuters) - Egyptian President Mohamed Mursi declared a month-long state of emergency in three cities on the Suez Canal, where dozens of people have been killed in protests that have swept the nation and deepened a political crisis facing the Islamist leader.

Hundreds of demonstrators in Port Said, Suez and Ismailia turned out against the decision within moments of Mursi's announcement late on Sunday, which came after the death toll from protests and violence that erupted last week hit 49.

Mursi also called for a national dialogue with his rivals for later on Monday, but the early response from members of the main opposition coalition suggested they saw little point, saying the president only seemed to listen to his allies.

Most deaths have been in Port Said, where 40 were killed in just two days. Riots were sparked on Saturday when a court sentenced to death several people from the city on charges related to deadly rioting at a soccer match last year. Mourners at Sunday's funerals in the port, where guns are common, directed their anger at Mursi.

Violence in Egypt's cities has extended to a fifth day. Police fired volleys of teargas at dozens of youths hurling stones on Monday near Cairo's Tahrir Square, where opponents have camped for weeks to protest against Mursi, who they say betrayed the revolution that ousted Hosni Mubarak two years ago.

"We want to bring down the regime and end the state that is run by the Muslim Brotherhood," said Ibrahim Eissa, a 26-year-old cook, protecting his face from teargas wafting towards him from police lines near Tahrir, the cauldron of the 2011 revolt.

Propelled to power in a June election by the Brotherhood, Mursi's presidency has lurched through a series of political crises and violent demonstrations, compounding his task of shoring up a teetering economy and preparing for a parliamentary election to cement the new democracy in a few months.

"The protection of the nation is the responsibility of everyone. We will confront any threat to its security with force and firmness within the remit of the law," Mursi said, offering condolences to families of victims in the canal zone cities.

"WASTE OF TIME"

Appealing to his opponents, the president called for a national dialogue on Monday at 6 p.m. (1600 GMT), inviting a range of Islamist allies as well as liberal, leftist and other opposition groups and individuals to discuss the crisis.

The main opposition National Salvation Front coalition gathered in Cairo to discuss a response, but several members have already suggested they do not expect much from the meeting, raising the prospect of poor attendance.

"Unless the president takes responsibility for the bloody events and pledges to form a government of national salvation and a balanced committee to amend the constitution, any dialogue will be a waste of time," Mohamed ElBaradei, a prominent politician who founded the Constitution Party, wrote on Twitter.

Hamdeen Sabahy, a leftist politician and presidential candidate who is another leading member of the Front, said he would not attend Monday's meeting "unless the bloodshed stops and the people's demands are met".

Ahmed Said of the liberal Free Egyptians Party said Mursi's tone on Sunday night was more threatening than conciliatory. "Egypt is in danger and completely split," he told Reuters.

Egypt's politics has become deeply polarized. Although Islamists have swept to victory in a parliamentary poll and presidential vote, the disparate opposition has been united by Mursi's bid late last year to expand his powers and fast-track a constitution with an Islamist hue through a referendum.

Mursi's opponents accuse him of listening only to his Islamist friends and reneging on a pledge to be a president for all Egyptians. Islamists say their rivals want to overthrow by undemocratic means Egypt's first freely elected leader.

The Front has distanced itself from the latest flare-ups but said Mursi should have acted far sooner to impose extra security measures that would have ended the violence.

BLAMING MURSI

"Of course we feel the president is missing the real problem on the ground, which is his own policies," spokesman Khaled Dawoud said. "His call to implement emergency law was an expected move, given what is going on, namely thuggery and criminal actions."

Even in Tahrir, some protesters said violence and the high death toll in Port Said and other cities on the strategic Suez waterway meant there was little choice but to impose emergency law, although they, too, blamed Mursi for fury on the streets.

"They needed the state of emergency there because there is so much anger," said Mohamed Ahmed, 27, a protester walking briskly from a cloud of teargas spreading into Tahrir Square.

However, activists in the three cities affected have pledged to defy the curfew that will start at 9 p.m. (1900 GMT) each evening and last until 6 a.m. (0400 GMT).

Some opposition groups have also called for more protests on Monday, which marks the second anniversary of one of the bloodiest days in the revolution that erupted on January 25, 2011, and brought an end to Mubarak's iron rule 18 days later.

Rights activists said Mursi's declaration was a backward step for Egypt, which was under emergency law for Mubarak's entire 30-year rule. His police used the sweeping arrest provisions to muzzle dissent and round up opponents, including members of the Brotherhood and even Mursi himself.

Heba Morayef of Human Rights Watch in Cairo said the police, still hated by many Egyptians for their heavy-handed tactics under Mubarak, would once again have the right to arrest people "purely because they look suspicious", undermining efforts to create a more efficient and respected police force.

"It is a classic knee-jerk reaction to think the emergency law will help bring security," she said. "It gives so much discretion to the Ministry of Interior that it ends up causing more abuse, which in turn causes more anger."

Wall Street Week Ahead: Bears hibernate as stocks near record highs

NEW YORK (Reuters) - Stocks have been on a tear in January, moving major indexes within striking distance of all-time highs. The bearish case is a difficult one to make right now.

Earnings have exceeded expectations, the housing and labor markets have strengthened, lawmakers in Washington no longer seem to be the roadblock that they were for most of 2012, and money has returned to stock funds again.

The Standard & Poor's 500 Index <.spx> has gained 5.4 percent this year and closed above 1,500 - climbing to the spot where Wall Street strategists expected it to be by mid-year. The Dow Jones industrial average <.dji> is 2.2 percent away from all-time highs reached in October 2007. The Dow ended Friday's session at 13,895.98, its highest close since October 31, 2007.

The S&P has risen for four straight weeks and eight consecutive sessions, the longest streak of days since 2004. On Friday, the benchmark S&P 500 ended at 1,502.96 - its first close above 1,500 in more than five years.

"Once we break above a resistance level at 1,510, we dramatically increase the probability that we break the highs of 2007," said Walter Zimmermann, technical analyst at United-ICAP, in Jersey City, New Jersey. "That may be the start of a rise that could take equities near 1,800 within the next few years."

The most recent Reuters poll of Wall Street strategists estimated the benchmark index would rise to 1,550 by year-end, a target that is 3.1 percent away from current levels. That would put the S&P 500 a stone's throw from the index's all-time intraday high of 1,576.09 reached on October 11, 2007.

The new year has brought a sharp increase in flows into U.S. equity mutual funds, and that has helped stocks rack up four straight weeks of gains, with strength in big- and small-caps alike.

That's not to say there aren't concerns. Economic growth has been steady, but not as strong as many had hoped. The household unemployment rate remains high at 7.8 percent. And more than 75 percent of the stocks in the S&P 500 are above their 26-week highs, suggesting the buying has come too far, too fast.

MUTUAL FUND INVESTORS COME BACK

All 10 S&P 500 industry sectors are higher in 2013, in part because of new money flowing into equity funds. Investors in U.S.-based funds committed $3.66 billion to stock mutual funds in the latest week, the third straight week of big gains for the funds, data from Thomson Reuters' Lipper service showed on Thursday.

Energy shares <.5sp10> lead the way with a gain of 6.6 percent, followed by industrials <.5sp20>, up 6.3 percent. Telecom <.5sp50>, a defensive play that underperforms in periods of growth, is the weakest sector - up 0.1 percent for the year.

More than 350 stocks hit new highs on Friday alone on the New York Stock Exchange. The Dow Jones Transportation Average <.djt> recently climbed to an all-time high, with stocks in this sector and other economic bellwethers posting strong gains almost daily.

"If you peel back the onion a little bit, you start to look at companies like Precision Castparts , Honeywell , 3M Co and Illinois Tool Works - these are big, broad-based industrial companies in the U.S. and they are all hitting new highs, and doing very well. That is the real story," said Mike Binger, portfolio manager at Gradient Investments, in Shoreview, Minnesota.

The gains have run across asset sizes as well. The S&P small-cap index <.spcy> has jumped 6.7 percent and the S&P mid-cap index <.mid> has shot up 7.5 percent so far this year.

Exchange-traded funds have seen year-to-date inflows of $15.6 billion, with fairly even flows across the small-, mid- and large-cap categories, according to Nicholas Colas, chief market strategist at the ConvergEx Group, in New York.

"Investors aren't really differentiating among asset sizes. They just want broad equity exposure," Colas said.

The market has shown resilience to weak news. On Thursday, the S&P 500 held steady despite a 12 percent slide in shares of Apple after the iPhone and iPad maker's results. The tech giant is heavily weighted in both the S&P 500 and Nasdaq 100 <.ndx> and in the past, its drop has suffocated stocks' broader gains.

JOBS DATA MAY TEST THE RALLY

In the last few days, the ratio of stocks hitting new highs versus those hitting new lows on a daily basis has started to diminish - a potential sign that the rally is narrowing to fewer names - and could be running out of gas.

Investors have also cited sentiment surveys that indicate high levels of bullishness among newsletter writers, a contrarian indicator, and momentum indicators are starting to also suggest the rally has perhaps come too far.

The market's resilience could be tested next week with Friday's release of the January non-farm payrolls report. About 155,000 jobs are seen being added in the month and the unemployment rate is expected to hold steady at 7.8 percent.

"Staying over 1,500 sends up a flag of profit taking," said Jerry Harris, president of asset management at Sterne Agee, in Birmingham, Alabama. "Since recent jobless claims have made us optimistic on payrolls, if that doesn't come through, it will be a real risk to the rally."

A number of marquee names will report earnings next week, including bellwether companies such as Caterpillar Inc , Amazon.com Inc , Ford Motor Co and Pfizer Inc .

On a historic basis, valuations remain relatively low - the S&P 500's current price-to-earnings ratio sits at 15.66, which is just a tad above the historic level of 15.

Worries about the U.S. stock market's recent strength do not mean the market is in a bubble. Investors clearly don't feel that way at the moment.

"We're seeing more interest in equities overall, and a lot of flows from bonds into stocks," said Paul Zemsky, who helps oversee $445 billion as the New York-based head of asset allocation at ING Investment Management. "We've been increasing our exposure to risky assets."

For the week, the Dow climbed 1.8 percent, the S&P 500 rose 1.1 percent and the Nasdaq advanced 0.5 percent.

In New Orleans, an unwelcome mat for Goodell

NEW ORLEANS (AP) — An effigy of NFL Commissioner Roger Goodell dangles from the front porch of a New Orleans home that is otherwise festively decorated with Saints paraphernalia.

With restaurants and bars gearing up for an influx of Super Bowl XLVII visitors, the "Refuse to Serve Roger Goodell" page on Facebook had 107 likes as of Friday.

A portrait of Goodell covers the bull's-eye on the dart board at Parkview Tavern.

And floats in the unabashedly lowbrow Krewe du Vieux parade in the French Quarter last weekend displayed larger-than-life likenesses of Goodell in acts that defy polite description.

New Orleans is celebrating the return of Saints coach Sean Payton after a season of NFL banishment as a result of the "bountygate" scandal — when the team ran a pay-for-hits program. But Goodell, who suspended Payton and other current and former Saints players and coaches last year for their roles in the system, is being ridiculed here with a vehemence usually reserved for the city's scandal-scarred politicians.

"They believe he completely used the Saints as an example of something that was going on league-wide," said Pauline Patterson, co-owner of Finn McCool's, an Irish Bar in the Mid-City neighborhood where the words "Go To Hell Goodell" are visible over the fireplace.

Some of Goodell's critics say the disarray resulting from what they believe were unfair suspensions led to the Saints' 7-9 performance this year — and a missed chance to make history.

"We had a real shot of being the first team in history to host the Super Bowl in our own stadium," Parkview Tavern owner Kathy Anderson said. "He can't give that back to us."

Goodell suspended the coaches and players after an investigation found the Saints had a performance pool offering cash rewards for key plays, including big hits. The player suspensions eventually were overturned, but the coaches served their punishments.

Mayor Mitch Landrieu is among those saying that people in this city, known for its hospitality and history, should mind their manners and remember the not-too-distant past.

"Roger Goodell has been a great friend to New Orleans, and it's a fact that he's one of the people instrumental to making sure that the Saints stayed here after Hurricane Katrina," Landrieu said in a statement. It was a reference to the days after the storm, when 80 percent of the city was underwater and the damaged Superdome became a shelter for thousands of the displaced.

Then-Commissioner Paul Tagliabue and his second-in-command, Goodell, are credited with working to keep the team from abandoning New Orleans for San Antonio.

"If not for Roger Goodell, we would not have this Super Bowl," Landrieu added. "And we will need him since we want to host another one."

Saints quarterback Drew Brees said the game is validation of everything the city's gone through to rebuild after Hurricane Katrina.

"There's no question, yeah. And I think people will see that when they come down, as soon as people come down that haven't been there in a while," Brees said Friday while in Hawaii for the Pro Bowl. "The city knows how to entertain, knows how to treat people right. The tourism industry's huge, so we're excited to host this big game. Obviously it's the biggest sporting event in the world, and the city will be ready for it."

But some are in no mood to back off when it comes to Goodell.

Anderson said she understands city leaders' desire to put their best foot forward, but that it also is important for Saints fans to be able to vent.

"Whether I have Roger Goodell's face on my dart board is not going to change anybody's mind about the Super Bowl," Anderson said.

People should not take the barbs too seriously, said Lynda Woolard, a Saints fan who has been tracking some of the barbs on social media. "Nobody's saying there should be violence against the man," Woolard said.

"It's tongue-in-cheek," Patterson agreed.

Still, some diehards are ready to put it all behind them.

Patrick Brower, owner and manager of the Dirty Coast T-shirt shop, said Friday that he's pushing black-and-gold wear at his shop, choosing to unify Saints fans without bashing the commissioner.

"We've got to look forward here," Brower said. "The more time we spend in the past, it's just not beneficial."

Bulgaria holds nuclear power referendum

SOFIA, Bulgaria (AP) — Bulgarians are voting in a referendum on whether a new nuclear power plant should be built in the European Union‘s poorest member country, a choice also seen as a barometer of the country’s relationship with Russia.

Sunday’s vote was called by the opposition Socialist party in an effort to force the government to reverse its decision to scrap a deal with Russia on the construction of a second nuclear plant.

Bulgaria’s first referendum since the fall of communism in 1989 has polarized opinion along party lines. It has been seen as a test ahead of general elections in July, but also as a chance to loosen Moscow’s energy grip.

The latest polls estimate a low turnout, which could make the referendum invalid. At least 60 percent of the electorate must take part.

STORY HIGHLIGHTS

• N. Korea said Thursday it plans to carry out new nuclear test and more long-range rocket launches


• It said they are part of new phase of confrontation with United States


• George A. Lopez says North Korea's aim is to be recognized as a 'new nuclear nation by fait accompli'


• The Security Council sanctions aim to deteriorate and disrupt N. Korea's programs, says Lopez

Editor's note: George A. Lopez holds the Hesburgh Chair in Peace Studies at the Kroc Institute, University of Notre Dame. He is a former member, UN Panel of Experts on DPRK.

Indiana, U.S. (CNN) -- North Korea has responded to new Security Council sanctions condemning its December 12 rocket launch with a declaration that it plans a third nuclear test and more missile launches. Politically, it has made unambiguous that its "aim" is its enemy, the United States.

In this rapid reaction to U.N. sanctions, the young government of Kim Jong Un underscores what Security Council members have long known anticipated from the DPRK. Their end-game is to create a vibrant, integrated missile and nuclear weapons program that will result - as in the cases of Pakistan and India - in their being recognized as a new nuclear nation by fait accompli.

In light of DPRK defiance - and a soon to occur nuclear test - the Security Council's first set of sanctions on North Korea since 2009 may seem absurd and irrelevant. These sanctions will certainly not prevent a new DPRK nuclear test. Rather, the new sanctions resolution mobilizes regional neighbors and global actors to enforce sanctions that can weaken future DPRK programs and actions.

The utility, if not the necessity, of these Security Council sanctions are to deteriorate and disrupt the networks that sustain North Korea's programs. Chances of this degradation of DPRK capabilities have increased as the new sanctions both embolden and empower the member states who regularly observe - but do nothing about - suspicious vessels in their adjacent waterways.

The resolution provides new guidance to states regarding ship interdiction, cargo inspections, and the seizure and disposal of prohibited materials. Regarding nuclear and missile development the sanctions expand the list of material banned for trade to DPRK, including high tech, dual-use goods which might aid missile industries.

These new measures provide a better structure for more effective sanctions, by naming new entities, such as a bank and trading companies, as well as individuals involved in the illicit financing of prohibited materials, to the sanctions list. To the surprise of many in the diplomatic community - the Council authorizes states to expose and confiscate North Korea's rather mobile "bulk cash." Such currency stocks have been used in many regions to facilitate purchases of luxury goods and other banned items that sustain the DPRK elites.

Finally, the Security Council frees the Sanctions Committee to act more independently and in a timely manner to add entities to the list of sanctioned actors when evidence shows them to be sanctions violators. This is an extensive hunting license for states in the region that can multiply the costs of sanctions to the DPRK over time.

Whatever their initial limitations, the new round of U.N. sanctions serve as a springboard to more robust measures by various regional and global powers which may lead back to serious negotiations with DPRK.

Despite its bluster and short-term action plan, Pyongyang recognizes that the wide space of operation for its policies it assumed it had a week ago, is now closed considerably. To get this kind of slap-down via this Security Council resolution - when the launch was a month ago - predicts that any nuke test or missile launch from Pyongyang will bring a new round of stronger and more targeted sanctions.

Read more: North Korea silences doubters, raises fears with rocket launch

Although dangerous - a new game is on regarding DPRK. Tougher U.N. measures imposed on the North generated a predictable response and likely new, prohibited action. While DPRK may be enraged, these sanctions have the P5 nations, most notably China, newly engaged. A forthcoming test or launch will no doubt increase tensions on both sides.

But this may be precisely the shock needed to restart the Six Party Talks. Without this institutional framework there is little chance of influencing DPRK actions. And in the meantime, the chances of greater degrading of DPRK capabilities via sanctions, are a sensible next best action.

A violent Saturday leaves 7 dead

Four shootings -- two of them double homicides -- and a stabbing left 7 people dead Saturday, authorities said.

In what appeared to be the last homicide of the day, a man in his 30s was fatally stabbed about 11:50 p.m. in the South Shore neighborhood, police said.

The stabbing happened during an argument in the 2500 block of East 73rd Street, Chicago Police News Affairs Officer Ron Gaines said.

The man was found unresponsive on the scene.

Less than two hours earlier, about 10:05 p.m., a man was killed in the Englewood neighborhood, making him the sixth person shot day Saturday, police said.

The 38-year-old man died on the scene, in the 7000 block of South Carpenter Street, Gaines said.

Earlier, in the second double homicide of the day, a 16-year-old boy and a 32-year-old man were gunned down in the West Garfield Park neighborhood about 5 p.m., police said.

Officers responded to a call of a person shot in the 4200 block of West Congress Parkway and found the two lying dead outside on the ground, according to the police.

Both victims lived in Chicago, police said. 

No one has been arrested.

Police had the crime scene near Genevieve Melody Elementary School taped off at least one block to the north, east and west, while neighbors milled about to get a better look.

On West Van Buren Street, a body could be scene lying in the roadway, near the curb and a bus stop.

A man who only identified himself as the teen victim's uncle said the boy, whose family lived nearby, had simply gone to run an errand.

"He was just going to the store," the man said. "They just killed him just like that."

Later, the man paced back and forth on the sidewalk, shaking his head in disbelief.

"He goes to school and everything," he said to a police officer.

This man and the boy were the 4th and 5th people killed today, and the shooting was the city's second double homicide.

Egyptian youths, police clash in fourth day of violence

CAIRO (Reuters) - Police fired tear gas at dozens of stone-throwing protesters in Cairo on Sunday in a fourth day of street clashes that have killed at least 41 people and compounded the political challenges facing President Mohamed Mursi.

In the worst violence, security sources said 32 people died in Port Said on Saturday when protests erupted following a court verdict sentencing 21 people, mostly from the city, to death for their role in a deadly stadium disaster last year.

Mursi's opponents have also taken to the streets across Egypt since Thursday, accusing him and his Islamist allies of betraying the uprising that overthrew Hosni Mubarak in 2011.

"Till now, none of the revolution's goals have been realized," said Mohamed Sami, a protester in Tahrir Square on Sunday. "Prices are going up. The blood of Egyptians is being spilt in the streets because of neglect and corruption and because the Muslim Brotherhood is ruling Egypt for their own interests."

On a bridge close to Cairo's Tahrir Square, youths hurled stones at police in riot gear who fired tear gas to push them back towards the square which was the cauldron of the uprising that erupted on January 25, 2011 and toppled Mubarak 18 days later.

The latest protests were initially timed to mark Friday's second anniversary of that revolt.

The U.S. and British embassies, which are both close to Tahrir, said they were closed for public business on Sunday.

The spasm of violence adds to the daunting task facing Mursi as he tries to fix a beleaguered economy and cool tempers before a parliamentary election expected in the next few months which is supposed to cement Egypt's transition to democracy.

It has also exposed a deep rift in the nation. Liberals and other opponents accuse Mursi of failing to deliver on economic promises and say he has not lived up to pledges to represent all Egyptians. His backers say the opposition is seeking to topple Egypt's first freely elected leader by undemocratic means.

DIVISIONS

The army, Egypt's interim rulers until Mursi's election in June, were sent back onto the streets to restore order in Port Said and Suez, another port city on the Suez Canal where at least eight people have been killed in clashes with police.

Although scuffles continued in Cairo, there was no immediate sign of the kind of deadly escalation of previous days in the capital or elsewhere.

In Port Said, residents heard gunshots overnight and shops and many workplaces were shut on Sunday. Residents said the city was tense and there was a risk of further unrest later in the day when the dead were due to be buried.

Many Egyptians are frustrated by the regular escalations that have hurt the economy and their livelihoods.

"They are not revolutionaries protesting," said taxi driver Kamal Hassan, 30. "They are thugs destroying the country."

The National Defence Council, headed by Mursi, has called for a national dialogue to discuss political differences.

That offer has been cautiously welcomed by the opposition National Salvation Front. But the coalition has demanded a clear agenda and guarantees that any agreements will be implemented.

The Front, formed late last year when Mursi provoked protests and violence by expanding his powers and driving through an Islamist-tinged constitution, has threatened to boycott the parliamentary poll and to call for more protests if a list of demands is not met, including having an early presidential vote.

Egypt's transition has been blighted from the outset by political rows and turbulence on the streets that have driven investors out and kept many tourists away, starving the economy of vital sources of hard currency.

Egypt's defence minister who also heads the army, Abdel Fattah al-Sissi, called for the nation to stand together and said the military would not prevent peaceful protests. But he called on demonstrators to protect public property.

Clashes in Port Said erupted after a judge sentenced 21 men to die for involvement in 74 deaths at a soccer match on February 1, 2012 between Cairo's Al Ahly club and the local al-Masri team. Many of the victims were fans of the visiting team.

There were 73 defendants in the case. Those not sentenced on Saturday will face a verdict on March 9, the judge said.

Al Ahly fans cheered the verdict after threatening action if the death penalty was not meted out. But Port Said residents were furious that people from their city were held responsible, triggering wild rampages through the streets.
