Modern Greenland Melt Echoed in 126,000-Year-Old Ice

A new look at the melting of Greenland’s ice sheet more than 115,000 years ago reveals that even though the climate was much warmer than today’s, the ice was only a few hundred feet thinner than in modern times.

Given that sea level was also much higher during this long-ago period, the findings mean that Antarctica must have experienced major melt to boost the oceans. These results could hint at what’s to come in today’s warming world, the researchers report Thursday (Jan. 24) in the journal Nature.

“Even though the warm Eemian period was a period when the oceans were 4 to 8 meters higher than today, the ice sheet in northwest Greenland was only a few hundred meters lower than the current level, which indicates that the contribution from the Greenland ice sheet was less than half the total sea-level rise during that period,” study researcher Dorthe Dahl-Jensen of the University of Copenhagen said in a statement.

Melting Greenland

Greenland is currently responding rapidly to global warming, shattering through the seasonal ice-melt record in the summer of 2012. Researchers estimate that Greenland has lost more than 200 million tons of ice each year since 2003, and recent models point to an ice sheet that is more sensitive to climate change than previously realized. In March 2012, European scientists reported in the journal Nature Climate Change that a rise of between 1.3 to 5.8 degrees Fahrenheit (0.8 to 3.2 degrees Celsius) in global average temperatures from preindustrial levels would melt Greenland’s ice sheet entirely. Earth’s surface temperatures are already up 1.3 degrees F (0.7 degrees C) from preindustrial temperatures, with average temperatures rising faster on the surface of Greenland.

But these models are limited by the data scientists have. Understanding the future of Greenland’s ice depends, in part, on learning how the ice sheet responded to temperature increases in the past. The international North Greenland Eemian Ice Drilling Project (NEEM) set out to drill deep into the ice sheet to reach layers of ice set down during the Eemian period a stunning 115,000 to 130,000 years ago.

This period was a warm interglacial, one of the many warm and cold periods the Earth has cycled through over the past millions of years. Today’s rapid warming is driven not by these cycles, but predominately by emissions of greenhouse gases, which trap heat in the atmosphere, scientists say.

Previous attempts to drill into Eemian ice turned up twisted and folded layers. This is the first time researchers have constructed a complete record of the climate from an Eemian ice core. They do this by looking at molecular variants called isotopes in the core, as well as trapped air bubbles that represent tiny time capsules of ancient atmosphere.

History of ice

The core revealed that temperatures in the Eemian peaked about 126,000 years ago, reaching about 14.4 degrees F (8 degrees C) hotter than the average temperature of the last millennium and warmer than climate models had estimated. Initially, more precipitation triggered by the warmer climate helped the ice sheet grow, rising in elevation about 689 feet (210 meters) higher than today. Eventually, however, the warm air caught up with the ice, diminishing it to about 427 feet (130 m) below its modern elevation.

The numbers reveal that despite the balmy temperatures, the ice sheet lost no more than 25 percent of its volume between 122,000 and 128,000 years ago. Additional calculations found that this much melt would have raised global sea levels by an average of about 6.6 feet (2 m). [Top 10 Surprising Results of Global Warming]

Total Eemian sea-level rise hit between 13 and 26 feet (4 to 8 m). Though water does expand when it gets warmer, some of the remaining mass must have been made up by melting in Antarctica, the researchers report.

“We now have evidence that confirms that the West Antarctic ice sheet was a dynamic and crucial player in global sea rise during the last interglacial period,” Jim White, the U.S. lead on the NEEM project and an ice core expert at the University of Colorado, Boulder, said in a statement.

That’s useful information for researchers trying to understand today’s polar ice dynamics. Research released in November 2012 found that between 1992 and 2011, Antarctica lost approximately 1,320 metric gigatons of ice, compared with 2,940 metric gigatons lost in Greenland.

The good news is that Greenland’s future ice melt may not be as bad as feared, at least if the Eemian is any model, Dahl-Jensen said. The bad news, she said, is that Antarctica may shed lots of ice in a warming world.

During their fieldwork, the researchers got a firsthand taste at what melting polar ice is like.

“We were completely shocked by the warm surface temperatures at the NEEM camp in July 2012,” Dahl-Jensen said. “It was even raining and just like in the Eemian, the meltwater formed refrozen layers of ice under the surface. Although it was an extreme event, the current warming over Greenland makes surface melting more likely and the warming that is predicted to occur over the next 50 to100 years will potentially have Eemian-like climatic conditions.”

STORY HIGHLIGHTS

• Anthony Cordesman: Questions for Hillary Clinton on Benghazi attack inevitable, important


• But political blame game useless, a discouraging message to diplomats, military advisers, he says


• He says in hindsight, warnings, pleas for support mistakenly make crisis seem obvious


• Writer: U.S. must focus forward: encourage, support risk-takers doing crucial work in field

Editor's note: Anthony H. Cordesman holds the Arleigh A. Burke Chair in Strategy at the Center for Strategic and International Studies. Follow CSIS on Twitter.

(CNN) -- Politics are politics, and partisan congressional challenges over the death of Ambassador Chris Stevens and other Americans in Benghazi, Libya, last September were inevitable.

But while some of the questions Secretary of State Hillary Clinton was asked in her appearance before the Senate Foreign Relations Committee bordered on politics at their worst, some represented democracy at its best: A legitimate challenge of how the government works. The fact is, we do need to ask serious questions about the way our diplomats function, how they are deployed and protected.

In her responses, Clinton took responsibility, as the top official in every department always must. The question now, however, is what, if anything, will we really learn from the events that led to the deaths of Stevens and his colleagues?

Anthony H. Cordesman

Do we actually learn something from their courage and sacrifice, and the similar experience of other American diplomats and officers that have faced similar attacks in the past? Or do we go on playing a pointless blame game, creating a climate that discourages our diplomats, U.S. military advisory teams and intelligence officers from taking necessary risks -- and relies even more on fortifying our embassies.

Three lessons here. The first: Virtually every post mortem that relies on the blame game has the same result. There is always someone who asked for more resources and warned of the risk before the event. There are always enough intelligence indicators so that once you go back -- knowing the pattern of actual events -- it becomes possible to predict the past with 20-20 hindsight.

The problem is that the post mortems and hearings tend to be useless. Every prudent security officer has always asked for more; the indicators that could provide warning with 20-20 hindsight will still be buried in a flood of other reporting that warns of crises that don't take place; U.S. officials will still have to deal with what intelligence experts call "noise" -- the vast amount of reporting and other data that make it impossible to sort out the right information until the event actually occurs and the patterns are known. All of this makes it hard to know what request or warning ever matters.

Opinion: Algeria hostage crisis shows jihadists on rise

Yes, intelligence and warning can always be improved if the post mortem is realistic and objective. But the resulting improvements will never be enough. No one will ever assess all the risks correctly, U.S. diplomats and other Americans will be vulnerable when they operate in a hostile environment, and risk-taking will remain inevitable.

The second lesson is that we cannot deal with crises like the political upheavals in the Arab world, or the more direct threats that countries like Iran and North Korea can pose, unless our diplomats and military advisers take risks -- and more casualties -- in the process.

Stevens and those around him did what had to be done. These are the teams that can help lead unstable countries towards democracy and stability. They are the crucial to our counterterrorism efforts in the field and to building up the military security capabilities of developing states. They are key to uniting given factions, creating effective governance, and persuading states to move toward development and greater concern for human rights.

They can only be effective if they are on the scene, work with the leaders and factions involved, and often go into harms way where there are terrorist and military threats. Like Stevens, they cannot wait for perfect security, stay in a safe area, or minimize risks and deal with the realities of Libya, filled with local power struggles, extremist elements and potential threats.

We need risk-takers. We need them in any country that is going through the kind of upheavals taking place in Libya, as well as in countries where our enemies operate, and semi-war zones like Afghanistan, Iraq, Somalia, Syria, and Yemen. We need diplomats, U.S. military advisory teams, and intelligence officers that reach far beyond our embassies and go into high risk zones. We need to reward and honor those risk-takers, not those who shelter in safety and avoid the risks they should take or fear their career will be damaged if anyone is killed or hurt.

Opinion: Algeria crisis is a wakeup call for America

The third lesson is that we do need to steadily strengthen our ability to provide secure mobility, better intelligence, better communications, and better protection for those diplomats, U.S. military advisory teams and intelligence officers. We need to be able to better provide emergency help to those American NGO personnel and businessmen who take similar risks.

We need both an administration and a Congress that look beyond the blame game and understand that some things are worth spending money on. We need them to understand that what we once called the Arab Spring is clearly going to be the Arab Decade, and we face different but equally real risks in the field in Asia, Africa, and Latin America.

It is far better -- and cheaper even, in the medium term -- to fund strong U.S. country teams, military advisers, counterterrorism teams and development efforts than to let nations collapse, to let extremists take over, to lose allies, and see American NGOs and businesses unable to operate.

We need to see what new methods and investments can protect our people in the field and reduce the risks they should be taking. The answer may be special communications, intelligence system, helicopters and armored vehicles, emergency response teams and new career security personnel to replace contractors and foreign nationals.

What the answer is not is partisan blame, risk avoidance, punishing those who do take risks for the result, and failing to make the improvements in security for risk takers -- while building larger fortress embassies. If you want to honor the Americans lost in the line of duty, focus on the future and not the past.

Pentagon chief to remove military ban on women in combat

Former Navy SEAL Dick Couch comments on U.S. Defense Secretary Leon Panetta's decision to lift the military's ban on women serving in combat.

WASHINGTON—

The U.S. military will formally end its ban on women serving in front-line combat roles, officials said on Wednesday, in a move that could open thousands of fighting jobs to female service members.

The move knocks down another societal barrier, after the Pentagon scrapped its “Don't Ask, Don't Tell” ban in 2011 on gays and lesbians serving openly in the military.

The decision by outgoing Defense Secretary Leon Panetta is expected to be formally announced on Thursday and comes after 11 years of non-stop war that has seen dozens of women killed in Iraq and Afghanistan.

They have represented around 2 percent of the casualties of those unpopular, costly wars, and some 12 percent of those deployed for the war effort, in which there were often no clearly defined front lines, and where deadly guerrilla tactics have included roadside bombs that kill and maim indiscriminately.

“This is an historic step for equality and for recognizing the role women have, and will continue to play, in the defense of our nation,” said Democratic Senator Patty Murray from Washington, the outgoing head of the Senate Veterans Affairs Committee.

The move was also welcomed by Democratic Senator Carl Levin of Michigan, the head of the Senate Armed Services Committee, who said it reflected the “reality of 21st century military operations.” In addition, the American Civil Liberties Union, which filed a suit in November seeking to force the Pentagon to end the ban, applauded the move.

The decision overturns a 1994 policy that prevents women from serving in small front-line combat units.

‘HISTORIC MOMENT'

Following the expected announcement on Thursday, the military services will have until May 15 to submit a plan for implementing the decision. That plan, which has to be approved by the defense secretary and notified to Congress, will guide how quickly the new combat jobs open up and whether the services will seek an exemption to keep some closed.

The policy would be implemented by 2016.

Anu Bhagwati, a former Marine captain and head of the Service Women's Action Network, said her decision to leave the Marine Corps in 2004 owed partly to the combat exclusion policy.

“I know countless women whose careers have been stunted by combat exclusion in all the branches,” said Bhagwati, who called the decision an “historic moment.”

“I didn't' expect it to come so soon,” she said.

For Panetta, the decision adds to his legacy as a secretary who oversaw the end of “Don't Ask, Don't Tell” and now started the process to end discrimination against women. Otherwise, his tenure has been dominated by budget wrangling, the end of the Iraq war and the troop reduction in Afghanistan.

President Barack Obama has nominated former Republican Senator Chuck Hagel as Panetta's successor.

The decision comes nearly a year after the Pentagon unveiled a policy that opened 14,000 new jobs to women but still prohibited them from serving in infantry, armor and special operations units whose main function was to engage in front-line combat.

Asked last year why women who had served in Iraq and Afghanistan conducting security details and house-to-house searches were still being formally barred from combat positions, Pentagon officials said the services wanted to see how they performed in the new positions before opening up further.

Nearly 300,000 women have been deployed in the U.S forces in the Iraq and Afghanistan wars over the past 11 years, or about 12 percent of the total. Women have counted some 84 hostile casualties in those wars.

Cameron promises Britons vote on EU exit

LONDON (Reuters) - Prime Minister David Cameron promised Britons a vote on quitting the European Union, rattling London's biggest allies and some investors by raising the prospect of uncertainty and upheaval.

Cameron announced on Wednesday that the referendum would be held by the end of 2017 - provided he wins a second term - and said that while Britain did not want to retreat from the world, public disillusionment with the bloc 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 in a speech, adding that his Conservative party would campaign for the 2015 parliamentary election on a promise to renegotiate the terms of 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."

A referendum would mark the second time British voters have had a direct say on the issue. In 1975, they decided by a wide margin to stay in, two years after the country had joined.

Most recent opinion polls have shown a slim majority would vote to leave amid bitter disenchantment, fanned by a hostile press, about the EU's perceived influence on the British way of life. However, a poll this week showed a majority for staying.

Cameron's position is fraught with uncertainty. He must come from behind to win the next election, secure support from the EU's 26 other states for a new British role, and hope those countries can persuade their voters to back the changes.

He also avoided saying exactly what he would do if he failed to win concessions in Europe, as many believe is likely.

Critics, notably among business leaders worried about the effect on investment, say that for years before a vote, Britain may slip into a dangerous and damaging limbo that could leave it adrift or effectively pushed out of the EU.

The United States, a close ally, is also uneasy about the plan, believing it will dilute Britain's international clout. President Barack Obama told Cameron last week that Washington valued "a strong UK in a strong European Union" and the White House said on Wednesday it believed Britain's membership of the EU was mutually beneficial.

Some of Britain's European partners were also anxious and told Cameron on Wednesday his strategy reflected a selfish and ignorant attitude. However, Angela Merkel, the leader of EU paymaster Germany, was quick to say she was ready to discuss Cameron's ideas.

FRENCH "NON"

French Foreign Minister Laurent Fabius was less diplomatic: "If Britain wants to leave Europe, we will roll out the red carpet," he quipped, echoing words Cameron used recently to urge France's rich to escape high taxes and move to Britain.

French President Francois Hollande repeated his refusal of special deals: "What I will say, speaking for France, and as a European, is that it isn't possible to bargain over Europe to hold this referendum," he said. "Europe must be taken as it is.

"One can have it modified in future but one cannot propose reducing or diminishing it as a condition of staying in."

Italian Prime Minister Mario Monti was more positive. He said he agreed with Cameron on the need to make the EU more innovative and welcomed the idea of a British referendum, saying he thought Britons would ultimately vote to stay in the bloc.

Billed by commentators as the most important speech of Cameron's career, his referendum promise ties him firmly to an issue that has bedeviled a generation of Conservative leaders.

In the past, he has been careful to avoid bruising partisan fights over Europe, an issue that undid the last two Conservative prime ministers, John Major and Margaret Thatcher.

His speech appeared to pacify a powerful Euroskeptic wing inside his own party, but deepen rifts with the Liberal Democrats, the junior partners in his coalition. Their leader, Deputy Prime Minister Nick Clegg, said the plan would undermine a fragile economic recovery.

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

"BREXIT"?

Cameron said he would take back powers from Brussels, saying later in parliament that, when it came to employment, social and environmental legislation, "Europe has gone far too far".

But such a clawback - still the subject of an internal audit to identify which specific powers he should target for repatriation to London - is likely to be easier said than done.

If Cameron wins re-election but then fails to renegotiate Britain's membership of the EU, a 'Brexit' could loom.

Business leaders have warned that years of doubt over Britain's EU membership would damage the $2.5 trillion economy and cool 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."

Cameron has been pushed into taking such a strong position partly by the rise of the UK Independence Party, which favors complete withdrawal from the EU and has climbed to third in the 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.

Euroskeptics in Cameron's party, who have threatened to stir up trouble for the premier, 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 holds the referendum remains as uncertain as the Conservatives' chances of winning the election. They trail the opposition Labour party in opinion polls, and the coalition is grappling with a stagnating economy as it pushes through unpopular public spending cuts to reduce a large budget deficit.

Labour leader Ed Miliband said on Wednesday his party did not want an in-or-out referendum.

EU REFORM

Cameron said he would campaign for Britain to stay in the EU "with all my heart and soul", provided he secured the reforms he wants. He made clear the Union must become less bureaucratic and focus more on free trade.

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.

Asked whether, if he did not succeed in his renegotiation strategy, would recommend a vote to take Britain out, he said only: "I want to see a strong Britain in a reformed Europe.

"We have a very clear plan. We want to reset the relationship. We will hold that referendum. We will recommend that resettlement to the British people."

Cameron said the euro zone debt crisis was forcing the bloc to change and that Britain would fight to make sure new rules were fair to the 10 countries that do not use the common currency, of which Britain is the largest.

Democratic consent for the EU in Britain was now "wafer thin", he said:

"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. But the question mark is already there: ignoring it won't make it go away."

A YouGov opinion poll on Monday showed that more people wanted to stay in the EU than leave it, the first such result in many months. But it was unclear whether that result was a blip.

Paul Chipperfield, a 53-year-old management consultant, said he liked the strategy: "Cameron's making the right move because I don't think we've had enough debate in this country," he said.

"We should be part of the EU but the EU needs to recognize that not everybody's going to jump on the same bandwagon."

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 don't want Britain to leave the EU," he told parliament later. "I want Britain to reform the EU."

In the 1975 referendum, just over 67 percent voted to stay inside with nearly 33 percent against.

Banks, commodity stocks lift S&P 500 to five-year high

NEW YORK (Reuters) - Bank and commodity shares led the benchmark Standard & Poor's 500 Index to a fresh five-year closing high on Tuesday on hopes that the global economy continues to mend.

Travelers' shares climbed after the insurer's results and lifted the Dow Jones industrial average to a new five-year closing high.

On Friday, both the Dow and the S&P 500 ended at five-year highs after the quarterly earnings season got off to a solid start. On Monday, the U.S. stock market was closed in observance of the Martin Luther King, Jr., holiday.

In Tuesday's session, the market also gained on signals that 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.

Investors, however, were cautious ahead of an increase in earnings reports and as the S&P 500 rose for a fifth straight session.

Jack de Gan, chief investment officer of Harbor Advisory Corp, in Portsmouth, New Hampshire, said better economic numbers in the United States and China, as well as more stabilization in Europe, were driving buyers into sectors associated with economic growth.

"Any (bearish) news could turn us down for a day or so," he said, referring to the recent string of gains.

Freeport-McMoRan Copper & Gold led gains in the materials sector after it reported a 16 percent rise in fourth-quarter profit on higher production. Shares gained 4.6 percent to $35.19.

The Dow Jones industrial average <.dji> rose 62.51 points, or 0.46 percent, to 13,712.21 at the close. The S&P 500 <.spx> gained 6.58 points, or 0.44 percent, to 1,492.56. The Nasdaq Composite <.ixic> added 8.47 points or 0.27 percent, to 3,143.18.

Tuesday's session marked the highest closes for both the Dow and the S&P 500 since December 2007.

Technology shares underperformed as concerns about Apple's ability to continue to grow at hyper speed and a weak outlook from Intel Corp diminished optimism about the sector's prospects. The S&P technology index <.splrct> added 0.16 percent for the day. In comparison, the S&P energy sector index <.spny>, the S&P financials index <.spsy> and the S&P basic materials index <.splrcm> each gained 0.9 percent.

But Google shares rose 4.8 percent to above $736 in extended-hours trading after the world's No. 1 search engine reported a jump in fourth-quarter revenue. Shares of IBM added more than 4 percent to trade above $204 after the world's largest technology services company reported earnings and revenue that beat estimates.

"We expected Q4 for many tech vendors would be weak because we were expecting a lot of companies sitting on their wallets until it became clear what was going to become of the fiscal cliff," Forrester analyst Andrew Bartels said about IBM.

"Given the fact it's Q4 and the cloud of fiscal cliff within it, it's a positive indication that especially tech software will be doing better in the next couple of months."

During the regular session, shares of blue chips Travelers, DuPont

, and Verizon Communications rose following earnings.

Travelers rose 2.2 percent to $77.95, a closing high. DuPont's shares gained 1.8 percent to $47.82. Verizon's stock rose 0.9 percent to $42.94.

Thomson Reuters data through Tuesday morning showed that 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 are forecast to have risen 2.6 percent. 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.

U.S.-listed shares of Research in Motion rallied 13 percent to $17.90 a day after its chief executive said the Canadian company may consider strategic alliances with other companies after the launch of devices powered by RIM's new BlackBerry 10 operating system.

About 6.2 billion shares changed hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, below last year's daily average of about 6.45 billion shares.

On the NYSE, advancers outnumbered decliners by a ratio of roughly 9 to 4. On the Nasdaq, five stocks rose for every three that fell.

Signs of improved sentiment toward world growth were also seen in European bond markets. The yield on Portugal's benchmark 10-year note fell below 6 percent for the first time since late 2010 on news that the country was set to tap the bond market this week for the first time since it was bailed out in 2011.

A Whale of a Boat Ride Caught on Video

What would you do if an animal the size of a submarine wanted to give you the once-over?

An inflatable boat full of tourists found out recently in Hawaii, when two humpback whales circled their boat for at least 10 minutes, according to a report by Hawaii News Now. The female humpback whale bumped up against the boat as if she were scratching her back, a crew member for the tour company, Captain Zodiac Rafting Expeditions, told the site.          

As the whales approached the boat, shouts of excitement ring out in a video posted online.  

Humpback whales seem the most curious of all the large whale species, said Jooke Robbins, a senior scientist at the Provincetown Center for Coastal Studies in Massachusetts and director of the center’s Humpback Whale Studies Program.

“It’s not just boat-related. A colleague of mine saw this curious approach at an iceberg,” Robbins told OurAmazingPlanet.

The way humpback whales approach boats, icebergs, clumps of seaweed or other large objects in the water is almost a stereotypical behavior, Robbins explained.

“They will circle around it, sometimes they will go belly up underneath it, and they are very careful in the approach,” she said. “Often, their eyes are closed while they are doing it.”

Sperm whale seeks robot

Humpbacks are the not the only curious whales, though. Deep-diving sperm whales, notorious for nipping fish off longline fishing lines in Alaska, are also starting to pop up on YouTube videos. In the underwater video seen here, a massive sperm whale checks out a remotely operated robot.

Because sperm whales aren’t at the surface as much as humpback whales, scientists know less about their behavior, Robbins said. She added, “There is certainly a type of apparent curiosity, such as approaching boats and other things, that has been seen in different forms in many of the large whales.” [Images: Sharks & Whales from Above]

Scientists still don’t understand what the inquisitive behavior represents to whales, Robbins said. For example, she is not convinced the humpback whale seen in the tourist video was scratching its back on the boat. “It takes them a while to go over and touch a novel thing,” she said. “They are very, very careful about touching.”

Keep your distance

Robbins did praise the tour company for their interaction with the whales. A “code of conduct” published by the National Oceanic and Atmospheric Administration  asks people to avoid approaching whales too closely. The guides let the whales come to them, which is permitted, and turned off their engines.

“It’s important to remember that something like this is a precious thing,” Robbins said. “It’s important to keep a respectful distance. Many of these species are still considered endangered, and where we like to look at them is in critical breeding habitat.”

Whale watching seasons started Aug. 30, 2012, in Hawaii, which may have been the earliest the mammals have ever been seen in the area, according to a statement from NOAA. About 10,000-12,000 humpback whales visit Hawaiian waters every year to mate, give birth and nurse their calves in the warm waters, where they are protected.

Davos (CNN) -- Veterans of Davos often refer to nature's awe-inspiring work as the Magic Mountain.

The name comes from an early 20th century novel by Thomas Mann -- reflecting on life in an alpine health retreat, and the mystery of time in this breath-taking setting.

Since the late 20th century, this ski resort has been synonymous with the World Economic Forum, which represents networking on its grandest scale.

This year nearly 40 world leaders -- a record for this annual meeting -- 2000 plus executives and it seems an equal number of people in the media, like yours truly, are in pursuit of them all. The setting is certainly more chaotic then a decade ago. The agendas of the Fortune 500 chief executives are to filled with bi-lateral meetings and back door briefings to allow for the spontaneity that made this venue unique.

Davos gets ready for leaders' gathering

HIDE CAPTION

I first came to Davos as a relatively junior correspondent in 1990, two months after the fall of the Berlin Wall. It was arguably then, after nearly two decades in the conference business, when the forum became a fixture on the global calendar.

Quest: U.S. economy to dominate Davos 2013

I can remember, quite vividly, working out of a bunker (like we do today) in the Davos Congress Centre. West German Chancellor Helmut Kohl sat side-by-side with his East German counterpart Hans Modrow. That meeting before the global community helped set the stage for monetary union, a huge unification fund for what became Eastern Germany and shortly thereafter German elections.

The early 90s at Davos were dominated by European reconstruction after the fall of communism. Former party bosses came to the forum to convince business leaders that a transition to market economics could be delivered. Boris Yeltsin made his Davos appearance during that chaotic transition from the USSR to today's Russia.

Davos 2013: New year, same old problems?

In 1992, Chinese Premier Li Peng used the setting here in the Alps to articulate plans for the country's economic opening up to the world. Not by chance, the architect of Washington's engagement with Beijing, the former U.S. Secretary of State Henry Kissinger also took a high profile that year.

Again only two years later in 1994, Yasser Arafat and Shimon Peres walked hand in hand on stage, holding a public dialogue leading up to the creation and recognition of the Palestinian Authority.

The World Economic Forum, as the saying goes, was positioned to be in the right place at the right time. While the author of the Magic Mountain talked about the complexity of time around World War I, in the 1990s time was compressed here.

The fall of communism, the lowering of global trade barriers, the opening up of China, the removal of apartheid in South Africa and the proliferation of the internet all unfolded in that decade.

Interactive: How's your economic mood?

As those events came together, so too did the major players as they made the journey to Davos. Michael Bloomberg, evolving as a global name in financial data and now the Mayor of New York City, sat alongside Microsoft CEO Bill Gates. U.S. President Bill Clinton outlined his party's historic move to the political center before a packed audience of global business executives.

To spice things up, rock stars and actors, as they became activists, chose the Davos platform: Bono, Richard Gere, Sharon Stone, Brad and Angelina would have the wealthiest and most powerful corporate titans freeze in their tracks.

Earlier this week, I walked into the main plenary hall as workers put the final touches on the stage and lighting. It is a venue which has welcomed countless political leaders and business executives, during internet booms and banking busts, in the midst of a Middle East crisis and even during the lead up to two Gulf Wars.

But that inter-play between geo-politics and business -- during the best and worst of times -- is what keeps the forum relevant. It allows this setting at the base of the Magic Mountain to endure and recreate something unique during what Mann rightly described as the ongoing complexity of our times.

Netanyahu turns to Iran after narrow election win

JERUSALEM (Reuters) - Hawkish Prime Minister Benjamin Netanyahu claimed victory in Israel's parliamentary election, shrugging off surprise losses to centre-left challengers and vowing on Wednesday to stop Iran from acquiring nuclear weapons.

However, Tuesday's vote, which also disappointed religiously inspired hardliners, may deflect the premier's focus on confronting Tehran and resisting Palestinian demands as Israel's secular, middle-class demanded new attention to domestic issues.

That, in turn, might draw Netanyahu toward a less fractious relationship with his key ally, U.S. President Barack Obama, who himself embarked on a new term this week with great ambitions.

Exit polls showed the Israeli leader's right-wing Likud and the ultra-nationalist Yisrael Beitenu would remain the biggest bloc in the 120-member assembly, but with only 31 seats, 11 fewer than the 42 the two parties held in the last parliament.

If the exit polls compiled by three local broadcasters prove correct - and they normally do in Israel - Netanyahu would be on course for a third term in office, perhaps leading a hardline coalition that would promote Jewish settlement on occupied land.

But his weakened showing in a vote which he had called nine months early in the hope of a strong mandate for his struggle with Iran, could complicate his efforts to forge an alliance with a stable and substantial majority in parliament.

"I am proud to be your prime minister, and I thank you for giving me the opportunity, for the third time, to lead the state of Israel," the 63-year-old leader told a cheering crowd in the early hours of Wednesday at his campaign headquarters.

Netanyahu said he planned to form as broad a governing coalition as possible, suggesting he would seek partners beyond his traditional ultra-nationalist and religious allies. His first call may be to Yair Lapid, a former television anchorman whose centrist, secular party came from nowhere to second place.

"The first challenge was and remains preventing Iran from obtaining nuclear weapons," Netanyahu said.

Iran denies it is planning to build an atomic bomb, and says Israel, widely believed to have the only nuclear arsenal in the Middle East, is the biggest threat to the region.

Netanyahu views Tehran's nuclear program as a threat to Israel's existence and has stoked international concern by hinting at possible Israeli military action to thwart it.

He has shunted Palestinian peacemaking well down the agenda despite Western concern to keep the quest for a solution alive.

The projections showed right-wing parties with a combined strength of 61-62 seats against 58-59 for the centre-left.

Lapid's Yesh Atid (There is a Future) party should have 18 or 19 seats, exit polls showed - a stunning result for a newcomer to politics in a field of 32 contending parties.

Lapid won support amongst middle-class, secular voters by promising to resolve a growing housing shortage, abolish military draft exemptions for Jewish seminary students and seek an overhaul of the failing education system.

He urged Netanyahu "to build as broad a government as possible so that we can bring about real change in Israel".

The once dominant Labor party led by Shelly Yachimovich was projected to take third place with 17 seats. She described Likud victory claims as "ridiculous" before final results were in.

"There is a very good chance, a very good chance, that tomorrow morning Benjamin Netanyahu will not be able to form a government," she declared at her party headquarters.

Reconciling views to build a cabinet will certainly be hard.

"YESH ATID SWEEP"

Some in Netanyahu's party acknowledged that the election had gone somewhat awry. "We anticipated we would lose some votes to Lapid, but not to this extent. This was a Yesh Atid sweep," Likud campaign adviser Ronen Moshe told Reuters.

Lapid said before the election he would consider joining a Netanyahu-led government. If that happens, the ultra-Orthodox religious parties which often hold the balance of power in parliament might lose some of their leverage.

After a lackluster campaign, Israelis voted in droves on a sunny winter day, registering a turnout of 66.6 percent, the highest since 2003. That buoyed centre-left parties which had pinned their hopes on energizing an army of undecided voters against Netanyahu and his nationalist-religious allies.

"A big majority of middle class Israelis have voted strongly against the priorities of the last government," said Dan Avnon, a political science professor at Hebrew University.

"These are the people who pay the taxes and serve in the army," he said. "I don't think they can be ignored."

Opinion polls before the election had predicted an easy win for Netanyahu, although the last ones suggested he would lose some votes to the Jewish Home party, which opposes a Palestinian state and advocates annexing chunks of the occupied West Bank.

The exit polls projected 12 seats for Jewish Home.

The biggest casualty was the centrist Kadima party, which was projected to win no seats at all. It had gained the highest number in the previous election in 2009, although its then leader Tzipi Livni failed to put together a governing coalition.

Full election results are due by Wednesday morning and official ones will be announced on January 30. After that, President Shimon Peres is likely to ask Netanyahu, as leader of the biggest bloc in parliament, to try to form a government.

WESTERN ANXIETY

Whatever permutation finally emerges, a Netanyahu-led government is likely to resist any push for a peace deal with the Palestinians that would come anywhere near satisfying the moderates who seek a viable independent state alongside Israel.

Naftali Bennet, high-tech millionaire son of American immigrants who leads the hard-right, pro-settler Jewish Home party, was projected to win 12 seats - disappointing for him but still making his group a likely member of a coalition.

Bennet, who advocates annexing West Bank land to Israel, told cheering supporters: "There is only one truth and it is simple. The Land of Israel belongs to the people of Israel."

Britain warned Israel on Tuesday it was losing international support, saying Jewish settlement expansion had almost killed off prospects for a two-state solution.

U.S.-brokered peace talks broke down in 2010 amid mutual acrimony. Since then Israel has accelerated construction in the West Bank and east Jerusalem - land the Palestinians want for their future state - much to the anger of Western partners.

Netanyahu's relations with Obama have been notably tense and Martin Indyk, former U.S. ambassador to Israel, told the BBC the election was unlikely to change that.

"President Obama doesn't have high expectations that there's going to be a government in Israel committed to making peace and is capable of the kind of very difficult and painful concessions that would be needed to achieve a two-state solution," he said.

But Aaron David Miller, once a senior U.S. adviser on the peace process, said a weakening of the right might improve ties: "The fact is, if (Netanyahu) goes with Lapid and he reaches out to the centre, you're going to end up with an American-Israeli rapprochement to a certain degree," Miller told CNN.

Tuesday's vote was the first in Israel since Arab uprisings swept the region two years ago, reshaping the Middle East.

Netanyahu has said the turbulence, which has brought Islamist governments to power in several countries long ruled by secularist autocrats, including neighboring Egypt, shows the importance of strengthening national security.

Foreign policy issues barely registered during the election campaign, with a poll in Haaretz newspaper on Friday saying 47 percent of Israelis thought social and economic issues were the most pressing concern, against just 10 percent who cited Iran.

A major problem for the next government, which is unlikely to take power before mid-March, is the stuttering economy.

Data last week showed the budget deficit rose to 4.2 percent of gross domestic product in 2012, double the original estimate, meaning spending cuts and tax hikes look certain.

Yen, Asian shares mark time before BOJ decision

TOKYO (Reuters) - The yen and Asian shares marked time on Tuesday as investors awaited the outcome of the Bank of Japan's policy meeting, with expectations running high for bold monetary easing measures aimed at reflating the world's third-largest economy.

The MSCI's broadest index of Asia-Pacific shares outside Japan <.miapj0000pus> was up 0.1 percent. The index was pulled down on Monday after briefly touching 17-1/2-month highs as Malaysian stocks suffered their biggest drop in 16 months on election risks.

European shares rose on Monday near two-year highs, with investors betting on an improving economy in Europe. Wall Street was closed for Martin Luther King Jr. Day.

Australian shares <.axjo> were up 0.5 percent to a fresh 20-month high early on Tuesday while South Korean shares <.ks11> opened almost flat.

Japan's benchmark Nikkei average <.n225> opened up 0.2 percent. The Nikkei has faced choppy trading over the past two sessions as the yen became more volatile ahead of the BOJ meeting. Tokyo shares have been rising in tandem with the yen's slide against major currencies. The Nikkei tumbled 1.5 percent on Monday after investors booked profits from the index's 2.9 percent rally on Friday. <.t/>

Early on Tuesday, the dollar inched down 0.1 percent against the yen at 89.51 yen, after touching a fresh 2-1/2-year high of 90.25 yen on Monday. The euro fell 0.3 percent to 119.11 yen, off its peak since May 2011 of 120.73 hit on Friday.

Markets have priced in the BOJ boosting its asset-buying and lending program by another 10 trillion yen and doubling its inflation target to 2 percent. The BOJ will announce its decision after it ends its two-day meeting later on Tuesday.

Sean Callow, senior currency strategist at Westpac bank in Sydney, noted a bit more uncertainty over the policy decision, given speculation about open-ended easing and removing the 0.1 percent floor on short term interest rates.

"The biggest risk for USD/JPY is a cautious 10 trillion yen increase in asset purchases and not much else new aside from the 2 percent target. The best case for USD/JPY bulls is an open-ended commitment to increase quantitative easing until the inflation target is met," Callow said in a note.

There's a perception in markets that even if investors cut their yen short positions in disappointment over the BOJ result, the yen's rebound was likely to be limited relative to its 13 percent decline against the dollar and a 20 percent drop versus the euro over the past two months, mainly due to expectations for more aggressive BOJ easing to drive Japan out of years of deflation and support the economy.

Overall market sentiment was likely to be supported by signs of a compromise to avert a U.S. fiscal crisis.

Republican leaders in the U.S. House of Representatives have scheduled a vote on Wednesday on a nearly four-month extension of U.S. borrowing capacity, aimed at avoiding a fight over the looming federal debt ceiling and shifting their negotiating leverage for spending cuts to other fiscal deadlines.

The Bundesbank said on Monday Germany's economic slump should be short-lived, adding that the euro zone's largest economy could have already bottomed out.

U.S. crude futures were down 0.2 percent to $95.35 a barrel.

Gold was steady around $1,689.81 an ounce.

Jim, John Harbaugh ready for rematch at Super Bowl

SANTA CLARA, Calif. (AP) — Jim and John Harbaugh have exchanged a handful of text messages, and plan to leave it at that. No phone conversations necessary while the season's still going. No time for pleasantries, even for the friendly siblings.

There is work to be done to prepare for the Super Bowl, prepare for each other, prepare for a history-making day already being widely hyped as "Harbowl" or "Superbaugh" depending which nickname you prefer.

"It doesn't matter who the coach is, what relationship you have with the person on the other side," 49ers coach Jim Harbaugh said so matter-of-factly Monday afternoon.

Their parents sure aren't picking sides for the Feb. 3 matchup in New Orleans.

These days, the Harbaughs' longtime coaching father, Jack, stays away from game-planning chatter or strategy sessions with his Super Bowl-bound coaching sons. Baltimore's John Harbaugh and little brother Jim have been doing this long enough now to no longer need dad's input.

Yet, they still regularly seek it. And, their father does offer one basic mantra: "Get ahead, stay ahead."

"Probably the greatest advice that I've ever been given and the only advice that I've ever found to be true in all of coaching, I think we mentioned it to both John and Jim ... the coaching advice is, 'Get ahead, stay ahead,'" Jack Harbaugh said.

"If I'm called upon, I'll repeat that same message."

His boys still call home regularly to check in with the man who turned both on to the coaching profession years ago, and the mother who has handled everything behind the scenes for decades in a highly competitive, sports-crazed family — with all the routine sports clichés to show for it.

The Harbaugh brothers will become the first siblings to square off from opposite sidelines when their teams play for the NFL championship at the Superdome.

Not that they're too keen on playing up the storyline that has no chance of going away as hard as they try.

"Well, I think it's a blessing and a curse," Jim Harbaugh said Monday. "A blessing because that is my brother's team. And, also, personally I played for the Ravens. Great respect for their organization. ... The curse part would be the talk of two brothers playing in the Super Bowl and what that takes away from the players that are in the game. Every moment that you're talking about myself or John, that's less time that the players are going to be talked about."

Both men love history, just not the kind with them making it.

"I like reading a lot of history ... I guess it's pretty neat," John Harbaugh offered Monday. "But is it really going to be written about? It's not exactly like Churchill and Roosevelt or anything. It's pretty cool, but that's as far as it goes."

Nice try, guys.

John watched the end of Jim's game from the field in Foxborough, Mass., as Baltimore warmed up for the AFC championship game. Jim called his sister's family from the team plane before takeoff after a win at Atlanta and asked how his big brother's team was doing against New England.

The improbable Super Bowl features a set of brothers known around the NFL as fierce competitors unafraid to make a bold move during the season. Unafraid to upset anyone who stands in their way.

In fact, each one made a major change midseason to get this far — John fired his offensive coordinator, while Jim boosted his offense with a quarterback switch from Alex Smith to Colin Kaepernick.

Leading up to Sunday's games, parents Jack and Jackie said they would wait to decide whether to travel to New Orleans if both teams advanced or stick to what has been working so well — watching from the comfort of their couch in Mequon, Wis.

"We enjoy it very much. We get down in our basement, turn on the television and just have a fantastic day watching outstanding football," Jack said last week. "We share our misery with no one but ourselves. Not only the misery, but the ups and downs, the ins and outs of an outstanding professional game."

And, no, the Harbaughs weren't looking ahead to a potential big trip to the Big Easy.

Jack insists his wife is quick to pull out that old sports cliche: "It's one game at a time. I think it's very appropriate," he said.

Jim figures they won't possibly miss this history-making game.

"I think they'll be there," he said with a smile.

The brothers, separated in age by 15 months, have taken different paths to football's biggest stage — years after their intense games of knee football at the family home. They tried to beat each other at cards, or whatever other game it was at the time. Sometimes, they tried to beat each other up. Sister, Joani Crean, often got in on the fun, too.

The 49-year-old Jim never reached a Super Bowl, falling a last-gasp pass short during a 15-year NFL career as a quarterback. The 50-year-old John never played in the NFL.

Still, both will tell you, "Who's got it better than us? No-body!" — one catchphrase they got from their dad.

"We can't put into words what it means to see John and Jim achieve this incredible milestone," their brother-in-law, Indiana basketball coach Tom Crean, said on Twitter. "We talked to Jim (before) his team plane left. All he wanted to know was how was John doing? How were they playing? One incredible family who puts the care, well-being and love for each other at the forefront like most families do. Again, we are very proud of them. Going to be exciting to watch it unfold."

John worked his way up from the bottom of the coaching ranks, while Jim was the star college quarterback at Michigan, a first-round draft pick and eventual Pro Bowler who made coaching his career once he retired.

John already has the one-up, while Jim's team is the early favorite. John's Ravens beat the 49ers 16-6 on Thanksgiving night 2011, in Jim's rookie season as an NFL coach — though both know that means nothing now.

"I just want everybody to know, that was a four-day deal and every story has been told," John said. "We're not that interesting. There's nothing more to learn. The tape across the middle of the room story, OK, you got it? It's OK. It was just like any other family, really. I really hope the focus is not so much on that. We get it, it's really cool and it's exciting and all that."

Said Jim, "Completely new business."

In spite of his efforts to avoid the topic, Jim did take the opportunity to express how proud he is of John.

"He's a great football coach, a real grasp of all phases — offense, defense, special teams. I think he could coordinate at least two of those phases and do it as well as anyone in the league," Jim said. "I've got half the amount of coaching experience he does. Again, it's not about us. I keep coming back to that. I'm really proud of my brother. I love him. That's the blessing part, that this is happening to him."

And, fittingly for the big brother, John feels the exact same way.
