New York ? Revelers erupted in cheers amid a confetti-filled celebration in New York’s Times Square to welcome in the new year, part of star-studded celebrations and glittering fireworks displays around the world to usher in 2012.

From New Zealand to New York, the world eagerly welcomed a new year today 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.

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 and sparked over Moscow’s Red Square, crowds on Paris’ Champs-Elysées boulevard popped Champagne corks at midnight.

‘A pretty tough year’

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 drops at midnight Saturday and put it through a test run, 400 feet above the street. The sphere, now 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 were crammed into spectator pens ringed by barricades, enjoying surprisingly warm weather for the Northeast this time of year. The National Weather Service said Saturday it was about 49 degrees in nearby Central Park. That’s about 10 degrees warmer than the normal high temperature this time of year.

Cautious hope

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.
