Question: (CNN) -- Airport hotels have always been necessary but unloved stopover spots for the depleted traveler, places to shower, rehydrate and let the body recuperate from the merciless rigors of flying. Yet checking into the Hilton Frankfurt Airport, which opened in December turned out to be much more. It's an example of the emerging generation of airport hotels that are intended to function as destinations, real places where one might reasonably stay longer than a single night. Some of the best and most spectacular airport hotels are in Asia: the Regal in Hong Kong; the Crowne Plaza in Singapore. Now the rest of the world is catching up, and the newest airport hotels in Europe, the United States, Latin America, and elsewhere are responding to the generalized craving for experience. And there's more going on than that: the increasing sophistication of these hotels parallels a reemergence of civilization—daring architecture; edible food—in airports themselves. Travel + Leisure: Innovative new airport terminals . The improved hotels are one component of a backlash against that shiny one-world placelessness that airports have long cultivated. Moreover, they are being retooled for a new breed of business traveler. "The nature of work is changing," says Erin Hoover, head of design for the Sheraton and Westin brands, "and it's very collaborative." Now airport hotels—like the newly opened Hilton in London, Novotel in Auckland, New Zealand, and Element in Miami—are catching up, bringing technology, design, and style to the international stopover. Hilton Frankfurt Airport . The Hilton Frankfurt Airport is a stylish, hyper-connected oasis. The hotel, along with the lower-priced Hilton Garden Inn, occupies the eastern end of the Squaire (a name meant to evoke town square and air), an ultra-elongated mixed-use complex that rests on angled columns atop a high-speed rail station, is adjacent to the airport's commuter train station, and is squeezed between two major autobahns. When Squaire managing director Christoph Nebl characterizes it as "the best-connected spot in Europe," he's not exaggerating. Travel + Leisure: America's safest airports . Sheraton Malpensa Hotel (Milan) A series of glass modules lined up like the teeth of a comb, this property makes for a fitting addition to a world capital of design. Atlanta Airport Marriott Gateway . Two minutes from the terminal via SkyTrain, the building is LEED certified and has a lobby floor made of terrazzo embedded with glass. Aloft San Francisco International Airport . A newly rehabbed Clarion Inn building—dropped ceilings have been removed to give the rooms at this hotel an airy feel, and an expanded lobby big enough for a bustling bar scene has been added. Travel + Leisure: America's best and worst Airports . Hilton Heathrow Terminal 5, U.K. From its glamorous all-white main lobby staircase and unusually glitzy light fixtures to perfectly manicured exterior grounds and a celebrity chef--helmed restaurant (Mr. Todiwala's Kitchen), this property has all the makings of a hotel hot spot. Element Miami . The Miami International Airport satellite of this Westin brand features the cutting-edge Pilot program, where electricity can be generated by guests using the hotel's stationary bikes. The fully equipped kitchens, nutritious menus, and bathrooms with mood-improving lighting attest to Element's health-conscious hospitality approach. ALT Hotel Pearson, Toronto . Original art, Egyptian cotton linens, an Italian-made Calla chair, and Fruits & Passion bath products lend sophisticated global flair to the 153-room ALT, part of Canadian hotel group Groupe Germain. Custom Hotel, Los Angeles . Relaunched and refreshed by Joie de Vivre in September 2011, this bombastic crash pad minutes from LAX appeals to your sense of whimsy with themed gimmicks, like the Pan Am--inspired staff uniforms and Hangar Lounge, the property's main lobby. Steigenberger Airport Hotel Berlin . When Berlin's long-awaited Brandenburg Airport opens in March 2013, so too will this grand 322-room property with an outdoor reflecting pool, nine meeting spaces, a lobby bistro, and a fitness center with a gym, sauna, and steam bath. Lotte City Hotel Gimpo Airport, South Korea . Understated and refined, this hotel provides a welcome break from its chaotic surroundings—a massive theme-park-mall complex within the airport. It opened in late 2011, with touch screen controls in the 197 rooms. Planning a getaway? Don't miss Travel + Leisure's guide to the World's Best Hotels .

Question: (CNN) -- Explorer Dennis Schmitt found an island nearly two years ago near Greenland. Fishermen pass by Greenland's Ilulissat fjord in this September 2004 picture. Such a discovery would usually elicit curiosity, even wonder perhaps, but it evoked mixed feelings for the explorer. The island was once thought to be a peninsula attached to Greenland by an ice shelf or a glacier. But such a large amount of ice melted, it revealed the distinct island. "I very quickly realized two things," he told CNN's Anderson Cooper during a visit to the island earlier this year. "One [was] that this was going to be significant because it was going to be an example of climate change." "The other thing was that it meant it was really happening. It wasn't a joke. It wasn't just statistics. It was really happening." He calls his discovery Warming Island. Many climatologists and scientists say arctic ice melt and other changes in the Earth's climate are the result of an increase in the world's temperature, a trend widely called global warming. Many global warming experts say the phenomenon, if unchecked, is capable of altering the world's climate and geography. In the worst-case scenario, experts say oceans could rise to overwhelming and catastrophic levels, flooding cities and altering seashores. Other scientists and observers, a minority compared to those who believe the warming trend is something ominous, say it is simply the latest shift in the cyclical patterns of a planet's life. Most of the scientific community believes that some warming is occurring across the globe and through some layers of the atmosphere. But why it is occurring and what that means for the future is scientifically and politically contentious. The Earth's temperature averages about 60 degrees Fahrenheit (about 16 degrees Celsius). The average surface temperature has warmed one degree Fahrenheit (0.6 degrees Celsius) during the last century, according to the National Research Council. The temperatures were relatively unchanged from 1880 to 1910, according to the U.S. Environmental Protection Agency. They rose till about 1945, cooled until about 1975 and have risen steadily to present day. There are several possible reasons for the warming, scientists say. A change in the Earth's orbit or the intensity of the sun's radiation could change, triggering warming or cooling. The reason most cited -- by scientists and scientific organizations -- for the current warming trend is an increase in the concentrations of greenhouse gases, which are in the atmosphere naturally and help keep the planet's temperature at a comfortable level. The amount of carbon dioxide in the atmosphere, for instance, has increased by 35 percent since the dawn of the industrial age, according to the United Nations' Intergovernmental Panel on Climate Change, commonly referred to as the IPCC. The presence of methane is now 151 percent above pre-industrial levels, but the rate of increase has slowed in recent decades, according to the EPA. Meanwhile, nitrous oxide increased by about 18 percent during the past 200 years. Many scientists and experts who have studied global warming believe the increase is primarily the result of human activities, like the burning of fossil fuels, emissions from vehicles and the clearing of forests. "For the last 30 years, there's no way there's anything natural that can explain it," Stephen Schneider, a professor of environmental studies at Stanford University in California, said. "A vast bulk of the knowledgeable and honest community ... will say the science is settled and humans are at least a majority of the reason behind the warming," he added. Many scientific organizations share Schneider's view, ranging from the national academies of the countries that comprise the G8 to the National Research Council, the American Meteorological Society and the American Geophysical Union. But there are those who do not share his view, and among the skeptics is Richard Lindzen, a professor of atmospheric sciences at the Massachusetts Institute of Technology. "We've suddenly taken to reading tea leaves," he said. "When we saw cooling from 1940 to 1970, we were proclaiming global cooling. Since then, there's been a few tenths of global warming, so we're proclaiming global warming." He believes the current warming trend is the result of natural variability, where a planet goes through phases of warming and cooling and the human contribution to it is minimal. "The Earth is always getting colder and warmer," he said. "It's always changing. In fact, this is true of any fluid-covered planet." Asked about glacial melt, which many observers point to as evidence of global warming, Lindzen said the way glaciers change and move are phenomena largely unexplained. "We don't know why, but it's perfectly clear that glaciers change even though the temperature is cooling at the place that they've occurred," he said. "What we're doing is cherry picking any event that occurs and then saying that's occurring due to global warming." Yet, for Schneider, it is a cause for concern and alarm. "We're already in serious melt, nobody can explain it. The models don't predict it," he said. "We don't know what's going on up there. All we know is that we could be triggering something really nasty." The greatest point of contention is the possible implications for future political and economic policies for the world's nations. The IPCC in February 2007 projected that if carbon dioxide levels doubled relative to pre-industrial levels, temperatures could rise between 3.6 to 8.1 degrees Fahrenheit (2 to 4.5 degrees Celsius) by 2100. The lower end of the range could cause more intense hurricanes, droughts, wildfires and flooding, Schneider said. The higher end could lead to the catastrophes commonly associated with the visions of Hollywood filmmakers. Uncertainties, however, plague such forecasts, which are based on computer simulations and models. The models contemplate factors associated with how the atmosphere, oceans and continents interact, all natural elements that have unpredictability intrinsic to them. "Exactly how much it's going to warm up, we don't know," Schneider said. "That it's going to warm up? I'd bet anything on that." E-mail to a friend .

Question: (CNN)  -- A controversial extra-time goal by William Gallas saw France reach the World Cup finals after a 1-1 home draw against the Republic of Ireland in Paris on Wednesday night. France were trailing 1-0 in the second leg, with the scores tied 1-1 on aggregate, when Arsenal central defender Gallas forced the ball home for the decisive goal. But TV replays showed that his former club teammate Thierry Henry had clearly handled the ball twice before passing to him to head home. Irish goalkeeper Shay Given frantically gestured to the referee and Damien Duff was booked for his protests, but the goal stood and Raymond Domenech's men eventually went through after surviving late pressure in the Stade de France. Robbie Keane had given the Republic a deserved first half lead as he scored after a fine cutback by Duff. The pair both had chances in the second half to put the game out of France's reach, but home keeper Hugo Lloris blocked Duff's effort after he was clean through and forced Tottenham star Keane wide from a similar position. Cristiano Ronaldo will be going to World Cup after his Portugal side won 1-0 in Bosnia-Herzegovina to claim it 2-0 on aggregate in their European playoff match in Zenica. Real Madrid star Ronaldo sat out both legs of the decider through injury, but despite his absence Portugal qualified for the World Cup for the third time in a row. Raul Meireles' second-half goal in the second leg gave them a comfortable victory in a tie deemed awkward after a slender victory in the first leg secured though a goal by Bruno Alves. A pass from Nan found Meireles, whose low shot found the net and sent the Portuguese, who reached the semifinals in 2006, through. Slovenia upset Russia to qualify for the World Cup finals for only the second time with a 1-0 home win in Maribor. Slovenia trailed 2-1 from the first leg and go through on the away goals rule with the aggregate score tied 2-2. Striker Zlatko Dedic, who plays for Bochum in the Bundesliga, scored on the stroke of halftime. He reacted first to a Valter Birsa cross from the right to grab the crucial goal. Guus Hiddink's men suffered a further setback when substitute striker Alexander Kerzhakov was shown the red card in the 68th minute. Andrei Arshavin set up substitute Pavel Pogrebnyak for a late chance as Russia forced for an equalizer which would have put them through, but Dedic should have scored a  second for Slovenia late on. 2004 European champions Greece are also through as they beat Ukraine 1-0 in Donetsk with Dimitrios Salpigidis scoring the only goal for the visitors on the half hour mark. The Panathinaikos striker beat the offside trap after a superb pass from Celtic's Georgios Samaras and slotted home. The teams played out a 0-0 draw on Saturday in the first leg in Athens. Ukraine pressed desperately for an equalizer in the second half but to no avail.

France through after controversial equalizer against Ireland in Stade de France .
Portugal reach World Cup finals with 1-0 win in Bosnia-Herzegovina .
Slovenia shock Russia to reach World Cup for second time .
Greece stun Ukraine in Donetsk to reach South Africa 1-0 on aggregate .
