U.K. Dash for Shale Gas a Test for Global Fracking

Thomas K. Grose in London

The starting gun has sounded for the United Kingdom's "dash for gas," as the media here have dubbed it.

As early as this week, a moratorium on shale gas production is expected to be lifted. And plans to streamline and speed the regulatory process through a new Office for Unconventional Gas and Oil were unveiled last week in the annual autumn budget statement by the chancellor of the exchequer, George Osborne.

In the U.K., where all underground mineral rights concerning fossil fuels belong to the crown, hydraulic fracturing, or fracking, could unlock a new stream of government revenue as well as fuel. But it also means that there is no natural constituency of fracking supporters as there is in the United States, birthplace of the technology. In the U.S., concerns over land and water impact have held back fracking in some places, like New York, but production has advanced rapidly in shale basins from Texas to Pennsylvania, with support of private landowners who earn royalties from leasing to gas companies.

A taste of the fight ahead in the U.K. came ahead of Osborne's speech last weekend, when several hundred protesters gathered outside of Parliament with a mock 23-foot (7-meter) drilling rig. In a letter they delivered to Prime Minister David Cameron, they called fracking "an unpredictable, unregulatable process" that was potentially toxic to the environment.

Giving shale gas a green light "would be a costly mistake," said Andy Atkins, executive director of the U.K.'s Friends of the Earth, in a statement. "People up and down the U.K. will be rightly alarmed about being guinea pigs in Osborne's fracking experiment. It's unnecessary, unwanted and unsafe."

The government has countered that natural gas-fired power plants would produce half the carbon dioxide emissions of the coal plants that still provide about 30 percent of the U.K.'s electricity. London Mayor Boris Johnson, viewed as a potential future prime minister, weighed in Monday with a blistering cry for Britain to "get fracking" to boost cleaner, cheaper energy and jobs. "In their mad denunciations of fracking, the Greens and the eco-warriors betray the mindset of people who cannot bear a piece of unadulterated good news," he wrote in the Daily Telegraph.

Energy Secretary Edward Davey, who is expected this week to lift the U.K.'s year-and-a-half-old moratorium on shale gas exploration, said gas "will ensure we can keep the lights on as increasing amounts of wind and nuclear come online through the 2020s."

A Big Role for Gas

If the fracking plan advances, it will not be the first "dash for gas" in the U.K. In the 1980s, while Prime Minister Margaret Thatcher battled with mining unions, she undercut their clout by moving the nation toward generating a greater share of its electricity from natural gas and less from coal. So natural gas already is the largest electricity fuel in Britain, providing 40 percent of electricity. (Related Interactive: "World Electricity Mix")

The United Kingdom gets about 10 percent of its electricity from renewable energy, and has plans to expand its role. But Davey has stressed the usefulness of gas-fired plants long-term as a flexible backup source to the intermittent electricity generated from wind and solar power. Johnson, on the other hand, offered an acerbic critique of renewables, including the "satanic white mills" he said were popping up on Britain's landscape. "Wave power, solar power, biomass—their collective oomph wouldn't pull the skin off a rice pudding," he wrote.

As recently as 2000, Great Britain was self-sufficient in natural gas because of conventional gas production in the North Sea. But that source is quickly drying up. North Sea production peaked in 2000 at 1,260 terawatt-hours (TWH); last year it totaled just 526 TWh.

Because of the North Sea, the U.K. is still one of the world's top 20 producers of gas, accounting for 1.5 percent of total global production. But Britain has been a net importer of gas since 2004. Last year, gas imports—mainly from Norway, Belgium, and the Netherlands—accounted for more than 40 percent of domestic demand.

The government hopes to revive domestic natural gas production with the technology that has transformed the energy picture in the United States—horizontal drilling into deep underground shale, and high-pressure injection of water, sand, and chemicals to create fissures in the rock to release the gas.

A Tougher Road

But for a number of reasons, the political landscape is far different in the United Kingdom. Britain made a foray into shale gas early last year, with a will drilled near Blackpool in northwest England. The operator, Cuadrilla, said that that area alone could contain 200 trillion cubic feet of gas, which is more than the known reserves of Iraq. But the project was halted after drilling, by the company's own admission, caused two small earthquakes. (Related: "Tracing Links Between Fracking and Earthquakes" and "Report Links Energy Activities To Higher Quake Risk") The April 2011 incident triggered the moratorium that government now appears to be ready to lift. Cuadrilla has argued that modifications to its procedures would mitigate the seismic risk, including lower injection rates and lesser fluid and sand volumes. The company said it will abandon the U.K. unless the moratorium is soon lifted.

A few days ahead of Osborne's speech, the Independent newspaper reported that maps created for Britain's Department of Energy and Climate Change (DECC) showed that 32,000 square miles, or 64 percent of the U.K. countryside, could hold shale gas reserves and thus be open for exploration. But a DECC spokeswoman said "things are not quite what it [the Independent story] suggests." Theoretically, she said, those gas deposits do exist, but "it is too soon to predict the scale of exploration here." She said many other issues, ranging from local planning permission to environmental impact, would mean that some tracts would be off limits, no matter how much reserve they held. DECC has commissioned the British Geological Survey to map the extent of Britain's reserves.

Professor Paul Stevens, a fellow of the Royal Institute of International Affairs, said the U.K. is clearly interested in trying to replicate America's shale gas revolution. "That's an important part of the story," he said, but trying to use the American playbook won't be easy. "It's a totally different ballgame." In addition to the fact that mineral rights belong to the crown, large expanses of private land that are commonplace in America don't exist in England. Just as important, there is no oil- and gas-service industry in place in Britain to quickly begin shale gas operations here. "We don't have the infrastructure set up," said Richard Davies, director of the Durham Energy Institute at Durham University, adding that it would take years to build it.

Shale gas production would also likely ignite bigger and louder protests in the U.K. and Europe. "It's much more of a big deal in Europe," Stevens said. "There are more green [nongovernmental organizations] opposed to it, and a lot more local opposition."

In any case, the U.K. government plans to move ahead. Osborne said he'll soon begin consultations on possible tax breaks for the shale gas industry. He also announced that Britain would build up to 30 new natural gas-fired power plants with 26 gigawatts (GW) of capacity. The new gas plants would largely replace decommissioned coal and nuclear power plants, though they would ultimately add 5GW of additional power to the U.K. grid. The coalition government's plan, however, leaves open the possibility of increasing the amount of gas-generated electricity to 37GW, or around half of total U.K. demand.

The U.S. Energy Information Administration (EIA) estimates that Europe may have as much as 600 trillion cubic feet of shale gas that could be recovered. But Stevens said no European country is ready to emulate the United States in producing massive amounts of unconventional gas. They all lack the necessary service industry, he said, and geological differences will require different technologies. And governments aren't funding the research and development needed to develop them.

Globally, the track record for efforts to produce shale gas is mixed:

• In France, the EIA's estimate is that shale gas reserves total 5 trillion cubic meters, or enough to fuel the country for 90 years. But in September, President Francois Hollande pledged to continue a ban on fracking imposed last year by his predecessor, Nicolas Sarkozy.
• Poland was also thought to have rich shale gas resources, but initial explorations have determined that original estimates of the country's reserves were overstated by 80 percent to 90 percent. After drilling two exploratory wells there, Exxon Mobil stopped operations. But because of its dependence on Russian gas, Poland is still keen to begin shale gas production.
• South Africa removed a ban on fracking earlier this year. Developers are eyeing large shale gas reserves believed to underlie the semidesert Karoo between Johannesburg and Cape Town.
• Canada's Quebec Province has had a moratorium on shale gas exploration and production, but a U.S. drilling company last month filed a notice of intent to sue to overturn the ban as a violation of the North American Free Trade Agreement.
• Germany's Environment Ministry has backed a call to ban fracking near drinking water reservoirs.
• China drilled its initial shale gas wells this year; by 2020, the nation's goal is for shale gas to provide 6 percent of its massive energy needs. The U.S. government's preliminary assessment is that China has the world's largest "technically recoverable" shale resources, about 50 percent larger than stores in the United States.

Closing Tax Loopholes Not Enough to Avert 'Cliff'?

Closing "corporate tax loopholes" sure sounds good to the average, non-corporate American -- so good, in fact, that politicians talk about it all the time.

House Speaker John Boehner's fiscal-cliff proposal purports to raise $1.6 trillion in revenue by "clos[ing] special-interest loopholes and deductions while lowering rates."

The White House, meanwhile, has complained that Boehner hasn't offered specific loopholes to cut.

On the other side of the aisle, House Democrats have repeatedly offered up "closing overseas tax loopholes" as a means to pay for spending bills -- a plan Republicans routinely reject. In the last two and a half years, President Obama has often been heard griping about writeoffs for corporate jets.

For both Republicans and Democrats, "corporate tax loopholes" are an old saw. But, like most things in politics, raising revenue from "loopholes" gets a bit stickier when the specifics are hashed out.

A misconception about tax "loopholes," some experts say, is that they're loopholes -- gaps in the tax law that corporations have exploited against the law's intent.

Fiscal Cliff Battle: President Obama vs. Speaker John Boehner Watch Video

"Most of these proposals were not 'loopholes,' these were incentives," said Eric Toder, co-director of the left-leaning Tax Policy Center.

For example, take the research-and-development tax credit. During the campaign, both Obama and Mitt Romney suggested making it permanent.

"One wouldn't call the research credit a loophole," Toder said.

Cashing in by closing the biggest "loopholes" could be a politically fraught endeavor. To generate meaningful revenue, House Republicans would have to sign off on measures that raised it from taxing the overseas profits of multinational corporations, from ending immediate writeoffs of equipment purchases, or from ending a credit for domestic manufacturing.

When the Joint Committee on Taxation scored some of these provisions, as part of a tax-reform bill pushed by Democratic Sen. Ron Wyden and then-GOP-senator Judd Gregg, it found the government could save significantly:

Savings Over 10 Years: 2011-2021

Taxing Overseas Profits of Multinational Corps: $582.7 billion. In other words, the "overseas tax loophole" Democrats are fond of trashing. While most countries with large economies tax only profits made at home, the U.S. code taxes all income everywhere. To offset the different, U.S. multinational corporations receive credits to prevent double taxing. They also can defer paying any tax on foreign income, until they transfer the money back to the United States.

Taxing that profit could generate significant revenue. But this could be controversial, and large corporations would fight it. A senior aide to one business lobbying group said ending foreign-income deferral would amount to double-taxing U.S. companies and put them at a disadvantage to foreign competitors; one supporter of ending deferral suggested U.S. companies have been able to hide profits overseas, avoiding taxes altogether.

21 workers gather at security firm to demand for wages

SINGAPORE: A group of workers, including 13 Singaporeans, gathered at their security firm on Monday morning demanding for payment of their wages.

21 local and Malaysian workers accused Elk Security for failing to pay their wages on time as well as contribute to their CPF accounts.

Following discussions between the Manpower Ministry (MOM) and the firm, all parties agreed that the November salaries will be paid on December 11.

MOM said there was a delay in the payment of the workers' salary for the month of November as the company director was overseas and the cheques could not be issued on time.

The ministry will also be investigating the employers for possible offences under the Employment Act.

India, China, Brazil to emerge as key global players: US report

WASHINGTON: Asia will have surpassed North America and Europe combined in terms of global power by 2030 with China, India and Brazil becoming especially important to the global economy, according to a new US intelligence assessment.

"The diffusion of power among countries will have a dramatic impact by 2030," says the fifth installment in the US National Intelligence Council's series aimed at providing a framework for thinking about the future released here Monday.

The report "Global Trends 2030: Alternative Worlds," released by the Office of the Director of National Intelligence, the apex body of 16 US intelligence agencies, says China alone will probably have the largest economy, surpassing that of the United States a few years before 2030.

"In a tectonic shift, the health of the global economy increasingly will be linked to how well the developing world does-more so than the traditional West," the report said.

"In addition to China, India, and Brazil, regional players such as Colombia, Indonesia, Nigeria, South Africa, and Turkey will become especially important to the global economy.

"Meanwhile, the economies of Europe, Japan, and Russia are likely to continue their slow relative declines," the report said.

Despite their growing economic clout, developing countries will face their own challenges, especially in their efforts to continue the momentum behind their rapid economic growth, it said.

With slowing growth China "faces the prospect of being trapped in middle-income status, with its per capita income not continuing to increase to the level of the world's advanced economies."

"India faces many of the same problems and traps accompanying rapid growth as China: large inequities between rural and urban sectors and within society; increasing constraints on resources such as water; and a need for greater investment in science and technology to continue to move its economy up the value chain," the report said.

"Insufficient natural resources - such as water and arable land - in many of the same countries that will have disproportionate levels of young men increase the risks of intrastate conflict breaking out, particularly in Sub-Saharan African and South and East Asian countries, including China and India," it said.

"Three different baskets of risks could conspire to increase the chances of an outbreak of interstate conflict: changing calculations of key players- particularly China, India, and Russia; increasing contention over resource issues; and a wider spectrum of more accessible instruments of war."

South Asia, the report said: "faces a series of internal and external shocks during the next 15-20 years. Low growth, rising food prices, and energy shortages will pose stiff challenges to governance in Pakistan and Afghanistan."

"Afghanistan's and Pakistan's youth bulges are large-similar in size to those found in many African countries. When these youth bulges are combined with a slow-growing economy, they portend increased instability."

However, it said, "India is in a better position, benefiting from higher growth, but it will still be challenged to find jobs for its large youth population. Inequality, lack of infrastructure, and education deficiencies are key weaknesses in India."

How the United States' international role evolves during the next 15-20 years was a big uncertainty, the report said.

"Whether the US will be able to work with new partners to reinvent the international system will be among the most important variables in the future shape of the global order," it said.

Plants Grow Fine Without Gravity

When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Royal Hoax: DJs 'Shattered' After Nurse's Suicide

The two Australian radio DJs who prank-called the London hospital where Kate Middleton was being treated last week said they were "shattered" and "gutted" after the nurse who answered their call apparently killed herself.

Shock jocks Mel Greig, 30, and Michael Christian, 25, cried as they spoke to Australia's Channel 9 overnight in their first public interview since Jacintha Saldanha, 46, the nurse who last week connected the pair to the duchess' room, was found dead Friday morning.

"I'm shattered, gutted, heartbroken," Christian said. "Mel and myself are incredibly sorry for the situation and what's happened. I had the idea. … It was just a simple harmless phone call. It was going to go on for 30 seconds. We were going to get hung up on."

FULL COVERAGE: Royal Baby

The host of the "2Day" FM radio show pretended to be Queen Elizabeth and Prince Charles, asking for an update on Middleton's condition when they called up King Edward VII Hospital in central London. With no receptionist on duty overnight, Saldanha answered the prank call and put it through.

"It was just something that was fun and light-hearted and a tragic turn of events that I don't think anyone had expected," Christian said.

Jacintha Saldanha Outrage: DJs Responsible for Prank Are in Hiding Watch Video

Saldanha was found dead Friday morning after police were called to an address near the hospital to "reports of a woman found unconscious," according to a statement from Scotland Yard.

Investigators have not said how she might have killed herself.

Greig cried today when asked about the moment she heard of the death of Saldanha, a mother of two.

"It was the worst phone call I've ever had in my life," she said through tears. "There's not a minute that goes by that we don't think about her family and the thought that we may have played a part in that is gut-wrenching."

The DJs said they never expected to get through to Middleton's nurse and assumed "the same phone calls had been made 100 times that morning," Christian said.

Grieg said, "We wanted to be hung up on with our silly voices and wanted a 20-second segment to air of us doing stupid voice. … Not for a second did we expect to even speak to Kate or even have a conversation with anyone at the hospital. We wanted to be hung up on."

The global backlash against the duo has been fierce, from online death threats to calls for prison time. Their radio station has announced it is banning phony phone calls altogether, and suspending advertising indefinitely.

Max Moore-Wilton, the chairman of Southern Cross Austereo, said in a letter Sunday to Lord Glenarthur, chairman of King Edward VII's Hospital, that the company is reviewing the station's broadcast policies, the AP reported.

"I can assure you we are taking immediate action and reviewing the broadcast and processes involved," Moore-Wilton said in the letter. "As we have said in our own statements on the matter, the outcome was unforeseeable and very regrettable."

Greig and Michael have been taken off the air, silenced indefinitely.

Taiwan urges Japan to apologise over sex slaves: report

TAIPEI: Taiwan President Ma Ying-jeou on Sunday urged Japan to apologise for using sex slaves from across Asia during World War II, local media reported.

Ma made the call at a conference in Taiwan on sexual slavery attended by elderly women from Taiwan, South Korea and the Philippines who had been forced into prostitution by the Japanese military during the war.

"Historical mistakes can be forgiven, but the lessons of history should not be forgotten," Ma said, according to the state-run Central News Agency.

"I feel that such an apology and compensation can sometimes be (most powerful)."

Time is running out as the number of surviving sex slaves -- referred to euphemistically as "comfort women" by Japan during the war -- is falling rapidly due to old age.

In Taiwan, a movement advocating the rights of former comfort women emerged two decades ago, when a total of 58 former sex slaves came forward, but the number is now down to eight, according to the news agency.

Historians say up to 200,000 young women, mostly from Korea but also from China, Indonesia, the Philippines and Taiwan, were forced to serve as sex slaves in Japanese army brothels.

The issue of a Japanese apology for using sex slaves is a long-running and contentious one.

In a landmark 1993 statement, then chief Japanese government spokesman Yohei Kono apologised to former comfort women and acknowledged Japan's involvement in causing their suffering.

But in remarks in 2007 that triggered a region-wide uproar, when then-Japanese prime minister Shinzo Abe said there was no evidence that Japan directly forced women to work as sex slaves.

India misguided, paranoid over China: Guha

Shreya Roy Chowdhury, TNN Dec 8, 2012, 06.12AM IST

MUMBAI: A good half-hour into the discussion on 'India, China and the World', historian Ramachandra Guha issued a disclaimer—all the three members on the panel had been to China only once. "We should learn their language, promote quality research, and have a panel on China driven by Chinese scholars," he said. And that was the general tenor of the debate—that the Indian attitude to China was influenced by a mix of ignorance, cautious optimism about partnerships and a whole lot of misguided paranoia. "Don't demonise the Chinese, please," Guha finally said in response to a question.

"China has existed in our imaginations," observed Sunil Khilnani, professor of politics and author of The Idea Of India. "There's been very little sustained engagement with the reality of China and very little of our own produced knowledge about China." It was after the events of 1962 ('war' in the popular imagination, 'skirmish' to the scholars participating in the discussion), explained Khilnani, that a miffed India "withdrew". It's the 50th anniversary of that exchange this year, and "what we haven't been able to do is learn from the defeat", observed Khilnani. Both could have benefited from greater engagement. "China has had a very clear focus on primary education and achieved high levels of literacy before its economic rise. It has also addressed the issue of land reform," said Khilnani. Guha added that China could learn from the "religious, cultural and linguistic pluralism" in India.

But China and India weren't always so out of sync with each other. Srinath Raghavan, a scholar of military history, got both Guha and Khilnani to talk about pre-1962 relations between the two when the picture was rosier. Tagore was interested in China and so was Gandhi. Both were very large countries with large populations and shared what Guha calls a "lack of cultural inferiority". "They were both," he continued, "also heavily dependent on peasant communities." Nehru was appreciative of China's will to modernize and industrialize and its adoption of technology to achieve those ends. In turn, Chinese politicians argued for Indian independence.

Things soured more, feel both Khilnani and Guha, after the Dalai Lama fled to India in 1959. "He was welcomed here as a spiritual leader but the intensification of the conflict dates to the Dalai Lama's flight," said Guha. Both Guha and Khilnani argued that Nehru's decision to not react aggressively to China's occupation of Tibet was, in the long run, the right one and prevented further "militarization" of the region. An audience member wondered if that didn't make India "China's puppet". Guha disagreed. "If there's a Tibetan culture alive today," he said, "it's not because of Richard Gere. Don't believe in the hypocrisy of the Western countries. Will they give them land, employment, dignified refuge? The Tibetans is one of the few cases in which our record is honorable."

But the difference in levels of development and the lopsided trade relations between the two countries have only fuelled the suspicions many Indians seem to harbour about China. People were worried, said Guha, even about cricket balls made in China. Audience questions reflected those worries. A member asked about China's "strategy to conquer the world" and its likely impact on India. Guha cautioned against stereotypes; Khilnani explained, "History is littered with the debris of states that have tried to dominate the world. What we're doing may be more long-lasting."

Gay Marriage: Will Justices Follow Popular Opinion?

The Supreme Court's announcement that it would hear two cases challenging laws prohibiting same-sex marriage has reinvigorated one of the most hotly contentious social debates in American history, a debate that has been fueled by a dramatic change in attitudes.

With some states taking significant steps towards legalizing gay marriage, the hearings come at a critical moment.

This week in Washington State, hundreds of same-sex couples lined up to collect marriage licenses after Gov. Christine Gregoire announced the passing of a voter-approved law legalizing gay marriage.

"For the past 20 years we've been saying just one more step. Just one more fight. Just one more law. But now we can stop saying 'Just one more.' This is it. We are here. We did it," Gregoire told a group of Referendum 74 supporters during the law's certification.

Washington is just the most recent of several states to pass legislation legalizing same-sex marriage, signifying a significant departure from previous thinking on the controversial subject.

READ: Court to Take Up Same-Sex Marriage

A study by the Pew Research Center on changing attitudes on gay marriage showed that in 2001 57 percent of Americans opposed same-sex marriage, while 35 percent of Americans supported it.

The same poll shows that today opinions have greatly shifted to reflect slightly more support for same-sex marriage than opposition -- with 48 percent of Americans in favor and 43 percent opposed.

In fact, just two years ago, 48 percent of Americans opposed same-sex marriage while only 42 percent supported it -- indicating that opinions have changed dramatically in the last couple of years alone.

Check Out Same-Sex Marriage Status in the U.S. State By State

It's hard to imagine that only 16 years ago, the fervent gay marriage debate led to the conception of the Defense of Marriage Act, which defines marriage as a union solely held between a man and a woman.

While debating the Defense of Marriage Act in September 1996, former Sen. Robert Byrd said: "If same-sex marriage is accepted, then the announcement will be official: America will have said that children do not need a mother and a father. Two mothers or two fathers will be OK. It'll be just as good. This would be a catastrophe."

Even a few short years ago a newly-elected President Obama did not support the legalization of gay marriage. It wasn't until earlier this year, at the end of hiss first term and with the impending election in sight, that the president told ABC's Robin Roberts the he'd "been going through an evolution on this issue."

Obama went on to attribute his shift in stance to the influence of his daughters.

"You know, Malia and Sasha, they've got friends whose parents are same-sex couples. It wouldn't dawn on them that somehow their friends' parents would be treated differently," he said. "That's the kind of thing that prompts -- a change in perspective."

Obama isn't the only one to experience an evolution in thinking on the matter of gay marriage. Attitudes towards same-sex marriage have shifted dramatically over the past decade across the board, particularly in the past few years.

Gone are the days when a majority of people opposed same-sex marriage; the days when gay politicians and supporters of same-sex marriage could not get elected.

Today, nine states and the District of Columbia allow same-sex unions -- a number likely considered inconceivable just a few short years ago. And yet, the same-sex marriage debate still begs for the answering of a question: Will this newfound public opinion, largely driven by young people, women and Democrats, have an effect on the Supreme Court's ultimate decision on the matter?

"I think (gay marriage is) just not a big deal for a lot of young people," Elizabeth Wydra of the Constitutional Accountability Center says.
