NEW YORK — From New Zealand to New York, the world eagerly welcomed a new year Sunday with confetti-filled celebrations, glittering fireworks displays and star-studded festivities.
For one night, at least, revelers gathered and hoped for a better future, saying goodbye to a year of hurricanes, tsunamis and economic turmoil that many would rather forget.
In New York, hundreds of thousands gathered at the crossroads of the world to witness a crystal ball with more than 30,000 lights that descended at midnight. Lady Gaga and Mayor Michael Bloomberg led the crowd in the final-minute countdown of the famed crystal-paneled ball drop.
Matheus Campos, a law student from Brazil, threw both arms in the air as the new year began in Times Square.
"It's awesome," he said.
Revelers in Australia, Asia, Europe and the South Pacific island nation of Samoa, which jumped across the international dateline to be first to celebrate, welcomed 2012 with booming pyrotechnic displays. Fireworks soared over Moscow's Red Square, crowds on Paris' Champs-Elysees boulevard popped Champagne corks at midnight.
But many approached the new year with more relief than joy, as people battered by weather disasters, joblessness and economic uncertainty hoped the stroke of midnight would change their fortunes.
"It was a pretty tough year, but God was looking after us and I know 2012 has got to be better," said Kyralee Scott, 16, of Jackson, N.J., whose father spent most of the year out of work.
Some New York revelers, wearing party hats and "2012" glasses, began camping out Saturday morning, even as workers readied bags stuffed with hundreds of balloons and technicians put colored filters on klieg lights. The crowds cheered as workers lit the crystal-paneled ball that would drop at midnight Saturday and put it through a test run, 400 feet above the street. The sphere, decorated with 3,000 Waterford crystal triangles, has been dropping to mark the new year since 1907, long before television made it a U.S. tradition.
In Times Square, hundreds of thousands people crammed into spectator pens ringed by barricades, enjoying surprisingly warm weather for the Northeast. The National Weather Service said it was about 49 degrees in nearby Central Park – about 10 degrees warmer than the normal high temperature.
As the country prepared for the celebration, glum wasn't on the agenda for many, even those who had a sour year.
"We're hoping the next year will be better," said Becky Martin, a former elementary school teacher who drove from Rockford, Ill., to Times Square after spending a fruitless year trying to find a job. "We're starting off optimistic and hoping it lasts."
Many expressed cautious hope that better times were ahead after a year in which Japan was ravaged by an earthquake and tsunami, hurricanes wreaked havoc across the country and a debt crisis devastated Europe's economy.
"Everybody's suffering. That's why it's so beautiful to be here celebrating something with everybody," said Lisa Nicol, 47, of Melbourne, Australia.
For all of the holiday's bittersweet potential, New York City always treats it like a big party – albeit one that now takes place under the watchful eye of a massive security force, including more than 1,500 police officers.
Dick Clark, who suffered a stroke in 2004, put in a few brief appearances mentioning that he has hosted his namesake New Year's Eve celebration for years, but said "tonight, it's better than ever." Clark, looking cheerful but struggling with his speech, introduced a performance by Lady Gaga and also assisted in the countdown. The show, hosted by Ryan Seacrest also featured a performance by Justin Bieber.
Natalie Tolli, a 13-year-old from Yonkers, said "it was the best time I ever had, especially seeing Justin Bieber in his red hat."
Her father, George Tolli, said he and his wife and three daughters and son waited since 2 p.m. to get their place.
"It was a pleasant surprise, very controlled," he said. "In my 51 years, I've never been here for New Year's. But I did it for the kids. And it was worth it."
In Las Vegas, fireworks were launched from eight rooftops at midnight. Police earlier shut down a four-mile section of the Strip to vehicle traffic, letting revelers party in the street. Casino nightclubs touted pricey, exclusive bashes hosted by celebrities including Kim Kardashian, Bruno Mars and Fergie.
Authorities reported only minor hiccups, including an ash tray canister fire on the 15th floor of the Paris Las Vegas hotel casino and an intermittent power outage at Bellagio that led to casino officials closing its buffet.
The Bellagio outage also affected a bank of slot machines and some guest rooms, but the problem was fixed before 8 p.m., allowing all gambling, nightclub parties and shows to go forward.
Thousands of New Year's celebrants turned out in Salt Lake City for a variety of events organized by the Downtown Alliance, while in Seattle crowds were treated to a fireworks display that included barrages from the top of the city's iconic Space Needle.
A typically busy New Year's Eve in Los Angeles became even busier as police and fire crews remained on alert for more arson attacks, after dozens of deliberately set car fires hit the city in the early morning hours of Friday and Saturday. Four suspicious car fires were reported Saturday evening.
Atlanta welcomed thousands to its downtown, where a giant peach dropped at midnight. Fireworks were launched from the top of the Space Needle in Seattle; in Houston, tens of thousands celebrated at a party with country singer Delbert McClinton.
In summer temperatures at Key West, Fla., three separate midnight drops took place. A giant facsimile of a conch shell was lowered at Sloppy Joe's Bar, Ernest Hemingway's favorite watering hole when he lived in Key West. At the Schooner Wharf Bar, the bar owner dressed as a pirate wench and dropped down from the mast of a tall sailing ship. And at the Bourbon Street Pub complex, a drag queen named Sushi descended in a glittering 6-foot red women's high heel.
The town of Eastport, Maine, lowered an 8-foot-long wooden sardine from a downtown building at midnight, in celebration of its sardine canning and fishing history.
In San Francisco, revelers lined the waterfront for the annual fireworks show.
The first worldwide celebrations started in the island nation of Samoa, which hopped across the international date line at midnight on Thursday, skipping Friday and moving instantly to Saturday.
Samoa and neighboring Tokelau lie near the dateline that zigzags vertically through the Pacific Ocean; both sets of islands decided to realign themselves this year from the Americas side of the line to the Asia side to be more in tune with key trading partners.
In Sydney, more than 1.5 million people watched the shimmering pyrotechnic display designed around the theme "Time to Dream." In London, some 250,000 people gathered to listen to Big Ben chime at the stroke of midnight. Scotland Yard reported they arrested 77 people during London's New Year's celebrations.
World leaders evoked 2011's struggles in their New Year's messages with some ambivalence.
French President Nicolas Sarkozy warned Europe's crisis is not finished and "that 2012 will be the year full of risks, but also of possibilities."
Pope Benedict XVI marked the end of 2011 with prayers of thanks and said humanity awaits the new year with apprehension but also with hope for a better future.
"We prepare to cross the threshold of 2012, remembering that the Lord watches over us and takes care of us," Benedict said. "In him this evening we want to entrust the entire world. We put into his hands the tragedies of this world of ours, and we also offer him the hopes for a better future."
In Brazil, heavy rains didn't halt parties as upward of 2 million people gathered on Copacabana beach in Rio de Janeiro and nearly as many on a main avenue in Sao Paulo, South America's biggest city. Massive fireworks displays and top music acts graced stages across the nation.
Brazil has seen healthy economic growth in recent years, as the country prepares to host the World Cup in 2014 and the Olympics in 2016. Growth, however, has stalled in recent months, and Brazilian leaders are trying to stimulate the economy in the new year.
"This was a good year for Brazil and I think things are only getting better, it feels like we're making big advances," said Fabiana dos Santos Silva, an 18-year-old student who gathered with hundreds of thousands of others on a main avenue in Sao Paulo.
Several people preparing to celebrate the holiday in the U.S. told the AP that they would usher in the New Year hoping the Congress would become a more cooperative place. Some talked about their hopes for the presidential election. Others said they hoped to hold on to their job, or find a new one to replace one they'd lost.
An Associated Press-GfK poll conducted Dec. 8-12 found that 62 percent of Americans are optimistic that the nation's fortunes will improve in 2012, and 78 percent hopeful that their own family will have a better year. Most wrote off 2011 as a dud.
Debbie Hart, 50, of Perry, Ga., called herself the "perpetual optimist" who believes each year will be better than the one before.
"I married a farmer. `Wait until next year. Next year will be better.' That's what I've been hearing for 30 years," said Hart. "I have faith."
