Stock futures edge up with effort to break "cliff" deadlock


NEW YORK (Reuters) - Stock index futures signaled a modestly higher open on Thursday as U.S. President Barack Obama returned to Washington to restart negotiations over the "fiscal cliff."


Obama cut short a Christmas holiday in Hawaii to fly back to the capital and make another push for a deal between Democrats and Republicans to head off tax hikes and spending cuts worth $600 billion set to begin on January 1.


In a sign of a possible way to break the deadlock in Congress, Republican House Speaker John Boehner said if the Democrat-controlled Senate were to pass a bill, the House would at least consider it.


A higher market open would put the S&P 500 on track to halt a three-day decline, but signs of an improving economy have taken a back seat to the fiscal cliff negotiations.


Initial claims for unemployment benefits dropped 12,000 to a seasonally adjusted 350,000 last week and the four-week moving average fell to the lowest since March 2008.


"Unfortunately jobless claims right now are kind of false readings until we know more," said Chris Kichurchak, vice president of Strategic Wealth Partners in Seven Hills, Ohio.


"It's one of those times right now where we have to see more out of Washington first before we have a full reading of what the future looks like for any growth in the economy."


Treasury Secretary Timothy Geithner announced the first of a series of measures that should push back the government's debt ceiling by around two months.


More data in the session at 10 a.m. will give investors a look at December consumer confidence and November new home sales. The Conference Board's main consumer confidence index is expected to show a reading of 70 versus the 73.7 reported in November while new-home sales are expected to be 378,000 annualized units.


S&P 500 futures rose 2.2 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures gained 9 points, and Nasdaq 100 futures climbed 6 points.


The benchmark S&P 500 index has fallen 1.7 percent over the past three sessions as negotiations over the budget crisis have stalled, its longest losing streak since mid-November.


But the S&P has recouped nearly all of its decline since the U.S. elections and is up 12.9 percent for the year, putting it on pace for its best year since 2009.


Marvell Technology Group trimmed earlier losses in premarket trading after it said it would seek to overturn a jury's finding of patent infringement. Marvell stock was down 4.1 percent at $7.10. Shares had fallen earlier after a federal jury found the company infringed two patents held by Carnegie Mellon University and ordered the chipmaker to pay $1.17 billion in damages.


BCD Semiconductor Manufacturing surged 94.5 percent to $7.74 in premarket action after the company agreed to be acquired by Diodes Inc for $151 million.

Peyton Manning, Peterson make Pro Bowl


NEW YORK (AP) — Peyton Manning and Adrian Peterson want to cap their sensational comebacks with Super Bowl appearances. For now, they can be proud of Pro Bowl spots.


So can Redskins quarterback Robert Griffin III, one of two rookies chosen Wednesday for the Jan. 27 NFL all-star game.


Manning missed all of the 2011 season with neck and back problems that required several operations. He then signed with Denver as a free agent and has led the Broncos on a 10-game winning streak to take the AFC West.


"I know there's great players out there in the NFL, but there's some great players on this team this year that deserve to go," said Manning, whose 12th Pro Bowl is a record for quarterbacks. He ranks fourth in league passing this year, has thrown 34 touchdowns and 11 interceptions.


Four other Broncos made the AFC roster: DE Elvis Dumervil, linebacker Von Miller, CB Champ Bailey and tackle Ryan Clady. Bailey's 12th appearance is a record for defensive backs.


"My goal has always been to go out and help the team win and play at a high level," Manning added. "Anything that comes along with that, like being honored as a Pro Bowl selection, is very humbling."


Minnesota's Peterson tore up his left knee on Christmas Eve last year, underwent major surgery, then was back for the season opener. He's gone from uncertain to unstoppable, running away with the rushing title with a career-high 1,898 yards and lifting the Vikings toward an NFC wild card.


"Coming into the season after going through the rehab process, I just told myself that I wanted to lead my team to a championship and make sure that I contribute and do my part," Peterson said. "I've been doing it."


Griffin is one of three rookie QBs who had superb debut seasons, along with Andrew Luck of Indianapolis and Russell Wilson of Seattle. Luck and Wilson weren't voted to the Pro Bowl by players, coaches and fans, although their teams are in the playoffs; Griffin can get to the postseason if Washington beats Dallas on Sunday.


"You can't play down those kind of things," Griffin said. "I've always said my whole football career that you don't play for awards. They just come. You don't say you're going to win the Heisman. You don't say you're going to win MVP. You go out and you prove it on the field, and if everyone feels that way then they'll give you that award."


San Francisco had the most players selected, nine, including six from its second-ranked defense. Houston was next with eight, six on offense.


Kansas City, despite its 2-13 record that is tied with Jacksonville for worst in the league, had five Pro Bowlers, including RB Jamaal Charles, who like Peterson is coming back from a torn ACL.


One other rookie, Minnesota kicker Blair Walsh, was chosen. Walsh has nine field goals of at least 50 yards, an NFL mark.


The AFC kicker is at the other end of the spectrum: Cleveland's Phil Dawson earned his first selection in his 14th NFL season.


"I deliberately tried not to know," Dawson said. "We wanted to watch the show with my kids. I had a really good idea what was going on, but it was a pretty priceless moment when we saw the name flash up on the screen. My kids went nuts 'cause my wife went nuts. That makes these 15 years of waiting worth it."


Another record setter will be heading to Honolulu: Detroit WR Calvin Johnson.


Johnson broke Jerry Rice's single-season yards receiving record and has 1,892 yards with a game left.


Falcons tight end Tony Gonzalez set the record for Pro Bowls at his position by being chosen for the 13th time.


The league's top two sackmasters, DEs Aldon Smith of San Francisco and J.J. Watt of Houston, were first-time selections. Watt has 20 1-2 sacks, one ahead of Smith; the NFL record is 22 1-2.


Other newcomers, along with Griffin, Walsh and Dawson, were AFC players tackle Duane Brown and guard Wade Smith of Houston; safety LaRon Landry of the Jets; kick returner Jacoby Jones of Baltimore; and punter Dustin Colquitt of Kansas City.


For the NFC, first-timers were Giants WR Victor Cruz; Atlanta WR Julio Jones; Seattle tackle Russell Okung and center Max Unger; San Francisco guard Mike Iupati, linebacker NaVorro Bowman and safety Donte Whitner; Chicago cornerback Tim Jennings and defensive tackle Henry Melton; Washington tackle Trent Williams and special teamer Lorenzo Alexander; Minnesota fullback Jerome Felton; Tampa Bay DT Gerald McCoy; and New Orleans punter Thomas Morstead.


Eight teams had no Pro Bowl players: Carolina, Philadelphia and St. Louis in the NFC, Tennessee, Buffalo, Jacksonville, San Diego and Oakland in the AFC.

The forgotten victims of gun violence




Chicago Mayor Rahm Emanuel, center, and other area officials call for stronger gun regulations at a news conference last week.




STORY HIGHLIGHTS


  • While America was mourning Newtown victims, guns were claiming lives elsewhere in U.S.

  • Authors: Media focus on mass shootings, but continuing violence also needs coverage

  • They say inner cities suffer an epidemic of gun killings, and young are particularly vulnerable

  • Authors: There is a day-by-day slaughter of children that must be stopped




Editor's note: Bassam Gergi is studying for a master's degree in comparative government at St. Antony's College, Oxford, where he is also a Dahrendorf Scholar. Ali Breland studies philosophy at the University of Texas at Austin.


(CNN) -- On the Sunday after the Newtown massacre, President Barack Obama traveled to Connecticut to comfort the grieving community. As the president offered what he could to the town, other American communities, in less visible ways, were grappling with their own menace of violence.


In Camden, New Jersey -- a city that has already suffered 65 violent deaths in 2012 , surpassing the previous record of 58 violent deaths set in 1995 -- 50 people turned out, some bearing white crosses, to mourn a homeless woman known affectionately as the "cat lady" who was stabbed to death (50 of the deaths so far this year resulted from gunshot wounds.)

In Philadelphia, on the same Sunday, city leaders came together at a roundtable to discuss their own epidemic of gun violence; the year-to-date total of homicides is 322. Last year, 324 were killed. Of those victims, 154 were 25 or younger. A councilman at the roundtable asked, "How come as a city we're not in an outrage? How come we're not approaching this from a crisis standpoint?"

The concerns go beyond Philadelphia. In the week following the Newtown massacre, there were at least a dozen gun homicides in Chicago, Detroit, Baltimore and St. Louis alone. In a year of highly publicized mass shootings, inner-city neighborhoods that are plagued by gun violence have continued to be neglected and ignored.


According to the Centers for Disease Control and Prevention, large metropolitan areas account for more than two-thirds of deaths by gun violence each year, with inner cities most affected. The majority of the victims are young, ranging in age from their early teens to mid-20s, and black.


To track these violent deaths, many communities and media organizations have set up agonizing online trackers -- homicide watches or interactive maps -- that show each subsequent victim as just another data point. These maps are representative of a set of issues far larger than the nameless dots suggest.


In the immediate aftermath of Newtown, as politicians and public figures across America grapple with the horrible truths of gun violence, far less visible from the national spotlight is the steady stream of inner-city victims.




Illegal firearms confiscated in a weapons bust in New York's East Harlem is on display at an October news conference.



The media is fixated, and with justification, on the string of high-profile massacres that have rocked the nation in Aurora, Colorado; Tucson, Arizona; Virginia Tech; and now in Newtown. Yet in many of America's neighborhoods most affected by the calamity of gun violence, there is a warranted exasperation -- residents are tired, tired of the ubiquity of guns, tired of fearing for their children's safety, tired of being forgotten.




Critiquing a narrow media focus doesn't deny the horrible, tragic nature of the massacre at Sandy Hook Elementary School; mass shootings, however, make up only a small fraction of America's shockingly high level of gun crime.




In his study "American Homicide," Randolph Roth showed that while the overall risk of being murdered is higher in America than it is in any other first-world democracy, homicide rates vary drastically among groups.




According to Roth, if current trends are maintained, one out of every 158 white males born today will be murdered, but for nonwhite males it is likely one of every 27 born today will be murdered.




The stark difference in these racial trends can be traced to the high levels of racial segregation in America's cities, which have created a spatial barrier between poor inner-city youths of color and more mainstream America -- a barrier that is often responsible for the lack of media and political attention paid to inner-city problems.


Many experts claim that actually it is the spectacular nature of mass shootings that naturally magnifies media coverage and explains the resonance of these tragedies to the broader public. Inner-city violence on its own, however, does not suffer from a lack of awful, spectacular violence and calamity. In fact, the gruesome nature of violence in inner cities has contributed to widespread social desensitization to gun violence. How then do we explain the differing public responses?



An indicator of the difference of attention levels lies in the tone of the public rhetoric in the wake of mass shootings: "This was supposed to be a safe community," and "This kind of thing wasn't supposed to happen here."


These statements imply that in America's leafy-green small towns and suburbs, gun violence is a shocking travesty; it strikes against America's perception of what is acceptable. In contrast, gun violence in the American metropolis has been normalized, and the public and media display a passive indifference toward the lives of inner-city youths.


This normalization of inner-city violence is due in part, to the isolation and segregation of America's ghettos from wider America, but it is also due to a sense that the victims of inner-city violence are responsible for their own condition.


As Robert Sampson, a professor at Harvard University, has highlighted, the gun violence in American cities is born out of neighborhood characteristics such as poverty, racial segregation and lack of economic opportunity. This shortened explanation for the high levels of inner-city violence has often been mistaken to imply that it is the direct choice of inner-city residents to remain either in poverty or in their segregated community that leads to their victimization.


In reality, the victims of inner-city gun violence are the victims of a dual tragedy. The first is that the poverty and segregation, which play a crucial role in spurring the downward cycle of crime, are the result of social arrangements predicated on longstanding oppression and prejudice.


Through a complex mix of violence, institutional arrangements and exploitation, black Americans were pressured into ghettos, which are the hotbeds of contemporary gun violence. Their inability to escape their conditions is not a choice but rather the byproduct of continued structural discrimination. Slowing the tide of inner-city deaths through gun control is therefore a modern-day civil rights issue.


If the refusal of America's national politicians to move on gun control before Newtown represents a political failure and a paucity of American will, then the disregard for the lives of inner-city youths stricken by gun violence on a daily basis is an illustration of the limits of American compassion.


The slaughter of young children en masse should be a moment of reckoning for any society, but there is a day-by-day, child-by-child slaughter occurring in America that has gone on too long and is yet to be reckoned with.


If Newtown should teach us anything, it is that all of us in America share this same short moment of life, and that we all seek to ensure safety, security and prosperity for our children.


As Vice President Joe Biden and the presidential task force meet to negotiate about what new gun laws to recommend, they must look to Sandy Hook Elementary and beyond. We need to protect the children of Newtown from the threat of future gun violence, but the children of Chicago and Camden and Detroit deserve the same long-term security.


We may not be able to ensure absolute security for America's children, but through smarter policy America can surely save more of its children from gun violence.

Man killed on Southwest Side













Homicide on California Avenue


Detectives investigate the scene of a shooting that left a 32-year-old man dead late Wednesday night.
(Peter Nickeas / Chicago Tribune / December 26, 2012)



























































A man died after he was shot in the face, chest and arms in the Gage Park neighborhood on the Southwest Side.


Federico Martinez was shot in an alley east of California Avenue just south of 54th Street about 10 p.m. Wednesday, according to authorities. He lived a few houses south of where he was killed.


Martinez was standing on the street with a woman when someone drove by in a light-colored truck with tinted windows and opened fire, police said.





Martinez was taken to Mount Sinai Hospital, where he was pronounced dead. The man's family gathered there after he was shot.


Eight detectives arrived at the scene and began their investigation early Thursday morning, their unmarked police cars crowding the narrow block of 54th Street between California and Fairfield avenues. 


A young woman wept next to red tape at the crime scene.

Peace envoy Brahimi, Syria diplomats in Moscow talks


MOSCOW (Reuters) - Russia will host Syria peace envoy Lakhdar Brahimi this week after Syrian officials held talks in Moscow on Thursday as part of a diplomatic drive to try to agree a plan to end the 21-month-old conflict, Russia's foreign ministry said.


Talks have moved to Moscow, a long-time Syria ally, after a flurry of meetings Brahimi held in Damascus this week, but the international envoy has disclosed little about his negotiations.


Brahimi, who saw Syrian President Bashar al-Assad on Monday and is planning to hold a series of meetings with Syrian officials and dissidents this week, is trying to broker a peaceful transfer of power.


More than 44,000 Syrians have been killed in a revolt against four decades of Assad family rule, a conflict that began with peaceful protests in March last year, but which has descended into civil war.


Past peace efforts have floundered, with world powers divided over what has become an increasingly sectarian struggle between mostly Sunni Muslim rebels and Assad's security forces, drawn primarily from his Shi'ite-rooted Alawite minority.


Syrian Deputy Foreign Minister Faisal Makdad and an aide held talks for less than two hours on Thursday with Foreign Minister Sergei Lavrov and Mikhail Bogdanov, the Kremlin's envoy for Middle East affairs, but declined to disclose details of their visit.


Syrian and Lebanese sources said Makdad had been sent to Moscow to discuss the details of a peace plan proposed by Brahimi.


Foreign Ministry spokesman Alexander Lukashevich played down the idea that a specific new proposal was on the table in Moscow talks, at least one agreed by Moscow and Washington.


Asked about rumors of a Russian-American plan to resolve the conflict, he said: "There has not been and is no such plan."


'TRYING TO FEEL A WAY OUT'


"In our talks with Mr. Brahimi and with our American colleagues, we are trying to feel a way out of this situation on the basis of our common plan of action that was agreed in Geneva in June," Lukashevich told reporters at a weekly briefing.


Setting the scene for a planned Russian meeting with Brahimi on Saturday, he said, "We plan to discuss a range of issues linked to a political and diplomatic settlement in Syria, including Brahimi's efforts aimed at ending the violence and the launch of a comprehensive national dialogue."


World powers believe Russia, which has given Assad military and diplomatic aid to help him weather the uprising, has the ear of Syria's government and must be a key player in peace talks.


Moscow has tried to distance itself from Assad in recent months and has said it is not propping him up, but Lukashevich reiterated its stance that Assad's exit from power could not be a precondition for negotiations.


Setting such a condition, he said, would violate the terms of an agreement reached by world powers in Geneva on June 30 that called for a transitional government in Syria.


Lukashevich said Russia continued to believe there was "no alternative" to the Geneva Declaration and repeated accusations that the United States has reneged on it.


"Our American colleagues and some others ... have turned sharply from this position, by 180 degrees, supporting the opposition and conducting no dialogue with the government - putting the opposition in the mood for no dialogue with the authorities but for overthrowing the authorities," he said.


"The biggest disagreement ... is that one side thinks Assad should leave at the start of the process - that is the U.S. position, and the other thinks his departure should be a result of the process - that would be the Russian position," Dmitry Trenin, an analyst at the Moscow Carnegie Center, told Reuters.


But Trenin said battlefield gains made by the Syrian rebels were narrowing the gap between Moscow and Washington.


On Saturday, Lavrov said that neither side would win Syria's civil war and that Assad would not quit even if Russia or China told him to. Bogdanov had earlier acknowledged that Syrian rebels might win.


Lavrov has said this month that Russia had no intention of offering Assad asylum and would not act as messenger for other nations seeking his exit.

Stock futures edge higher ahead of "cliff" talk resumption

NEW YORK (Reuters) - Stock index futures pointed to a slightly higher open on Wednesday, indicating the S&P 500 may stem its worst two-day drop since mid-November, ahead of the resumption of "fiscal cliff" negotiations.


President Barack Obama, after vacationing in Hawaii, is due back in Washington early Thursday for a final effort to negotiate a deal with Congress to avert or at least postpone the cliff, a series of tax increases and government spending cuts set to begin next week.


"This is what we've come to - the President might get on a plane today and this is what the markets might react to," said Kim Forrest, senior equity research analyst at Fort Pitt Capital Group in Pittsburgh.


"It's all about the fiscal cliff."


A Republican plan that failed to gain traction last week triggered the recent decline in the S&P 500 <.spx>, highlighting market sensitivity to headlines centered around the talks.


Data showed U.S. single-family home prices rose in October, reinforcing the view the domestic real estate market is improving, as the S&P/Case Shiller composite index of 20 metropolitan areas gained 0.7 percent in October on a seasonally adjusted basis.


S&P 500 futures rose 1.9 points and were slightly above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures gained 23 points, and Nasdaq 100 futures climbed 3.25 points.


The benchmark S&P index is up 13.4 percent for the year, and has recouped nearly all of the losses suffered in the wake of the U.S. elections, when the fiscal cliff concerns moved to the forefront of investors' focus.


Retailers will be in focus as data on the holiday shopping season begins to come in.


"The broad brush was that Christmas wasn't all that merry for retailers and you have to ask what those margins look like if the top line didn't meet their expectations," said Forrest.


China's Sinopec Group and ConocoPhillips will research potentially vast reserves of shale gas in southwestern China over the next two years, state news agency Xinhua reported.


An outage at one of Amazon.com Inc's web service centers hit users of Netflix Inc's streaming video service on Christmas Eve and was not fully resolved until Christmas Day, a spokesman for the movie rental company said on Tuesday.

James leads Heat over Thunder in Finals rematch


MIAMI (AP) — Kevin Durant and Russell Westbrook combined to score 54 points, more than any set of teammates had managed in a game against Miami all season.


Oklahoma City needed them to score at least three more.


That didn't happen, and an NBA Finals rematch went just as last year's title series did — to the Heat.


LeBron James had 29 points, nine assists and eight rebounds, Dwyane Wade scored 21, and the Heat survived a frantic finish to beat the Thunder 103-97 on Tuesday night, a game where Durant and Westbrook both missed potential tying 3-pointers in the final seconds.


"A great game to play," Thunder coach Scott Brooks said, "and a great game to coach."


For the Heat, it was just a little greater.


Mario Chalmers scored a season-high 20 for the Heat, who were 19 for 19 from the foul line, the second-best effort in franchise history behind only a 30-for-30 game in Boston on March 24, 1993. Chris Bosh added 16 points for Miami, which has beaten the Thunder five straight times dating to last June's title series.


"Felt a little bit like a different month," Heat coach Erik Spoelstra said. "Regardless of what your script is coming into the game, when you play this team, it's not going to go according to script. They're too good."


It's the first losing streak of the season for the Thunder, who had been 4-0 after losses. Serge Ibaka and Kevin Martin each scored 15 for Oklahoma City.


The game had a little of everything — a fast start by the reigning champions, a one-handed dunk by James on an offensive rebound that will be added to his copious highlight reel, a scrum after a hard foul that led to double-technicals on Wade and Ibaka early in the fourth, an easy rally by the Thunder from an early double-digit deficit, and even workout partners in Durant and James barking back and forth in the final minutes.


Such was the intensity that James slumped over the scorer's table with 1:08 left, exhausted.


"I'm tired as hell right now," James said — and that was more than an hour after the game ended.


With good reason. On an emotional day, there was a wild finish.


Wade lost the ball on an ill-advised, behind-the-back dribble, and the turnover set up Durant for a two-handed dunk that got the Thunder within 96-95 with 44.1 seconds remaining.


Needing a stop on the next trip, the Thunder instead forgot to play defense. Kendrick Perkins and Ibaka both were confused on the ensuing Miami possession, and Bosh was left alone to take a pass from James and throw down a dunk that restored Miami's three-point edge.


"We went over and helped," Durant said. "We just needed to help on the backside. There was miscommunication but we still had a chance to go into overtime."


Two chances, actually.


Oklahoma City got within one when Durant made a jumper over James, but no closer. Ray Allen's two free throws with 15.6 seconds left made it 100-97, and Miami's last three points came from the line. Durant missed a 3-pointer that James contested, Westbrook wound up with a second chance that Wade defended, and the Thunder guard smacked a nearby table arguing that he was fouled.


"Part of the game," Westbrook said.


While the stars were stars, the Heat got help from one unexpected source. Chalmers was making everything, even unintended plays. Allen lost possession on what looked to be a pass to no one, but Chalmers picked up the bouncing ball on the right wing, whirled and made a 3-pointer — putting Miami up 86-79 with 8:14 left.


In the end, that cushion was necessary.


"I got going early," Chalmers said, "and I stuck with it."


The Heat came out flying, opening a quick 13-2 lead after making six of their first seven shots. About all that didn't go right for the Heat early on was James committing a foul, the first time he was called for a personal since Dec. 8.


It happened 4:03 into the game — 254 minutes and 7 seconds of on-court time since his last one — when James fouled Ibaka on a dunk attempt.


Chalmers had 12 points, matching his season high, in the opening quarter alone, and that was also Miami's lead after his layup for a 15-3 edge. When Durant headed to the bench after being called for his second personal, plus a technical, with 2:08 left in the first, the Heat led 27-16.


But even with Durant out, Oklahoma City scored the last eight points of the quarter, six coming from the line. The Thunder shot 17 of the game's first 18 free throws and finished with a 38-19 edge in tries from the stripe.


The Heat were held to two points in the first 5:05 of the third, and the Thunder grabbed the lead for the first time. Durant connected on a baseline jumper while falling out of bounds and getting fouled by James. The resulting free throw gave Oklahoma City a 58-56 edge.


With that, the back-and-forth began, and Miami found a way.


"Both teams really played up to the billing," Wade said. "An excellent basketball game."


NOTES: James scored at least 20 points for the 30th straight regular-season game and 46th overall. ... Wade is 7-1 on Christmas, and James has won six straight on the holiday. ... Miami's Mike Miller became the 48th active player to reach 10,000 points. ... The Thunder have used the same starting lineup for all 27 games. ... James passed Bernard King for 39th on the NBA career scoring list. ... Attendance was 20,300, the largest crowd for a Heat home game since they moved into AmericanAirlines Arena.

Erratic Environment May Be Key to Human Evolution






At Olduvai Gorge, where excavations helped to confirm Africa was the cradle of humanity, scientists now find the landscape once fluctuated rapidly, likely guiding early human evolution.These findings suggest that key mental developments within the human lineage may have been linked with a highly variable environment, researchers added.


Olduvai Gorge is a ravine cut into the eastern margin of the Serengeti Plain in northern Tanzania that holds fossils of hominins — members of the human lineage. Excavations at Olduvai Gorge by Louis and Mary Leakey in the mid-1950s helped to establish the African origin of humanity.






The Great Drying?


To learn more about the roots of humanity, scientists analyzed samples of leaf waxes preserved in lake sediments at Olduvai Gorge, identifying which plants dominated the local environment around 2 million years ago. This was about when Homo erectus, a direct ancestor of modern humans who used relatively advanced stone tools, appeared.


“We looked at leaf waxes, because they’re tough, they survive well in the sediment,” researcher Katherine Freeman, a biogeochemist at Pennsylvania State University, said in a statement.


After four years of work, the researchers focused on carbon isotopes — atoms of the same element with different numbers of neutrons — in the samples, which can reveal what plants reigned over an area. The grasses that dominate savannasengage in a kind of photosynthesis that involves both normal carbon-12 and heavier carbon-13, while trees and shrubs rely on a kind of photosynthesis that prefers carbon-12. (Atoms of carbon-12 each possess six neutrons, while atoms of carbon-13 have seven.)


Scientists had long thought Africa went through a period of gradually increasing dryness — called the Great Drying — over 3 million years, or perhaps one big change in climate that favored the expansion of grasslands across the continent, influencing human evolution. However, the new research instead revealed “strong evidence for dramatic ecosystem changes across the African savanna, in which open grassland landscapes transitioned to closed forests over just hundreds to several thousands of years,” researcher Clayton Magill, a biogeochemist at Pennsylvania State University, told LiveScience. [Know Your Roots? Take Our Human Evolution Quiz]


The researchers discovered that Olduvai Gorge abruptly and routinely fluctuated between dry grasslands and damp forests about five or six times during a period of 200,000 years.


“I was surprised by the magnitude of changes and the rapid pace of the changes we found,” Freeman told LiveScience. “There was a complete restructuring of the ecosystem from grassland to forest and back again, at least based on how we interpret the data. I’ve worked on carbon isotopes my whole career, and I’ve never seen anything like this before.”


Losing water


The investigators also constructed a highly detailed record of water history in Olduvai Gorge by analyzing hydrogen isotope ratios in plant waxes and other compounds in nearby lake sediments. These findings support the carbon isotope data, suggesting the region experienced fluctuations in aridity, with dry periods dominated by grasslands and wet periods characterized by expanses of woody cover.


“The research points to the importance of water in an arid landscape like Africa,” Magill said in a statement. “The plants are so intimately tied to the water that if you have water shortages, they usually lead to food insecurity.”


The research team’s statistical and mathematical models link the changes they see with other events at the time, such as alterations in the planet’s movement. [50 Amazing Facts About Earth]


“The orbit of the Earth around the sun slowly changes with time,” Freeman said in statement. “These changes were tied to the local climate at Olduvai Gorge through changes in the monsoon system in Africa.”


Earth’s orbit around the sun can vary over time in a number of ways — for instance, Earth’s orbit around the sun can grow more or less circular over time, and Earth’s axis of spin relative to the sun’s equatorial plane can also tilt back and forth. This alters the amount of sunlight Earth receives, energy that drives Earth’s atmosphere. “Slight changes in the amount of sunshine changed the intensity of atmospheric circulation and the supply of water. The rain patterns that drive the plant patterns follow this monsoon circulation. We found a correlation between changes in the environment and planetary movement.”


The team also found links between changes at Olduvai Gorge and sea-surface temperatures in the tropics.


“We find complementary forcing mechanisms — one is the way Earth orbits, and the other is variation in ocean temperatures surrounding Africa,” Freeman said.


These findings now shed light on the environmental shifts the ancestors of modern humans might have had to adapt to in order to survive and thrive.


“Early humans went from having trees available to having only grasses available in just 10 to 100 generations, and their diets would have had to change in response,” Magill said in a statement. “Changes in food availability, food type, or the way you get food can trigger evolutionary mechanisms to deal with those changes. The result can be increased brain size and cognition, changes in locomotion and even social changes — how you interact with others in a group.”


This variability in the environment coincided with a key period in human evolution, “when the genus Homo was first established and when there was first evidence of tool use,” Magill said.


The researchers now hope to examine changes at Olduvai Gorge not just across time but space, which could help shed light on aspects of early human evolution such as foraging patterns.


Magill, Freeman and their colleague Gail Ashley detailed their findings online Dec. 24 in two papers in the journal Proceedings of the National Academy of Sciences.

Climate change: No consensus needed




Lake Cachet II in Aysen, Chilean Patagonia, disappeared because of rising temperatures driven by climate change, experts say.




STORY HIGHLIGHTS


  • Tseming Yang: Result of Doha climate change conference less than desirable

  • Yang: It's time to abandon the myth that a consensus solution is the best approach

  • He says the 25 major carbon emitters should work out an agreement among themselves

  • Yang: Smaller, focused discussions may be better than large, U.N.-style gatherings




Editor's note: Tseming Yang, former deputy general counsel at the Environmental Protection Agency, is professor of law at Santa Clara University Law School.


(CNN) -- The Doha climate change conference this year was the most significant in nearly 20 years of gatherings under the U.N. Framework Convention process aimed at staving off future global warming disaster.


Since carbon dioxide emission limits agreed to under the 1997 Kyoto Protocol were to expire at the stroke of midnight on December 31, 2012, it was critical that the international community agreed to extend those obligations and to continue talks about future emission cuts.


But the outcome fell far short of what will be necessary to keep the world's average temperature from rising more than 2 degrees Celsius in the foreseeable future.


Under the Doha arrangement, 17 of the 25 biggest carbon emitting countries (including China, the United States, Russia and India) did not commit to any legally binding emission limits. The countries that did agree to extend and deepen their Kyoto emission reductions, including the European Union, Australia and Eastern Europe, make up only about 15% of the world's emissions. That seems like a rather meager return on the investment of time and effort over the past years.


But there is one silver lining.



The world's top 20 carbon emitters together make up about 77% of emission and account for about 4.3 billion people, which is about 62% of the global population. The remaining 170 or so countries account for just over 20% of emissions.


As often is the case, these negotiations over climate have come to symbolize epic David and Goliath struggles pitting poor developing countries against recalcitrant government officials from rich countries. Lobbying efforts, shaming tactics, and staging public demonstrations have been the slingshots of choice. One result is that more people are paying attention to environmental issues.


Nonetheless, it is time to abandon the myth that a consensus solution is necessarily the best approach. The unfortunate reality is that little can get done right now. It's like having hundreds of cooks with hundreds of different recipes attempting to prepare one meal in the same small kitchen. After two decades of hard work, it is time to consider reducing the number of cooks.








A better alternative to a United Nations-style conference would be for the 25 major emitters to come to an agreement just among themselves about their mutual commitments to deal with climate change effectively.


In other words, get the 25 cooks to work together on the main meal. The hundreds of other cooks ought to step out of the kitchen.


Some smaller, focused discussions have already started, such as in the Major Economies Forum. Imagine what kind of deals on cutting emissions would be possible just among China, India and the United States -- the top three emitters in the world respectively. Imagine a deal involving emission sources in China, which has some of the world's most polluting coal-fired power plants, and California, which is on a course to become one of the most stringently controlled states in carbon emissions.


Of course, there are no guarantees for success. But discussions within such a smaller group would allow government leaders to confront the realities of climate change and engage in direct horse-trading without the static of thousands of other voices desiring to load their issues into the deal.


Let's face it -- we are way beyond the time for finding an ideal solution. Every year the world waits to take further concrete steps to cut emissions, the atmosphere will be loaded with millions of tons more carbon dioxide that will stay for a century. And the job of limiting global warming to 2 degrees Celsius will be more out of reach.


At the best, gatherings like the one in Doha dangle a tantalizing mirage of achieving a sustainable future. At the worst, they give cover to governments that would rather avoid the hard choices they ultimately will have to make.


After one more expensive and time-consuming round of talks, it's time to be honest with what can really be accomplished in these U.N.-style gatherings.
