Bronx-born U.S. Supreme Court Justice Sonia Sotomayor led the 60-second countdown and pushed the button that unleashed the shimmering orb with 2,688 crystals, a role usually filled by the New York City mayor. Mayor Michael Bloomberg, on his last day in office, was sitting the celebration out after 12 years on the job, while newly elected Mayor Bill de Blasio took the oath of office just after midnight at his Brooklyn home.
Kerrie McConaghy, 20, a university student visiting Times Square from Armagh, Ireland, was dancing and jumping up and down, donning a big blue top hat.
"It's unbelievable here," she said. "The lights, seeing the ball, hearing the music, all the people. It's amazing."
"TV doesn't do this justice," she said. "You have to be here to believe it."
The annual New York celebration, which this year featured performances from artists such as Miley Cyrus, Macklemore & Ryan Lewis and Blondie, has become part endurance sport because post-Sept. 11, 2001 security measures force spectators into pens at least 12 hours in advance, with no food, warmth or bathrooms.
"We've got adult diapers. We're wearing them right now," said 14-year-old Amber Woods, who came with friends from New York City's suburbs to experience the event for the first time. They entered their corral at 10 a.m. Tuesday. For nourishment, they brought lollipops and popcorn. For the cold, they did a lot of jumping in place.
"Every time I say, it's the last. But then I come back," said Yasmina Merrir, a 42-year-old Washington, D.C., resident attending her fourth Times Square ball drop. In 2009, the cold was so bad, she got hypothermia. Her legs swelled up like balloons.
Merrir was fasting and not drinking anything to deal with the lack of restrooms. As for the cold, she recommended vigorous dancing for as long as you can stand on your feet.
"At a point," she said, "your brain is not working anymore."
On the other side of the Atlantic, London welcomed 2014 with a mixture of futuristic fireworks and torch-lit tradition.

In Dubai, a Persian Gulf city known for glitz, glamour and over-the-top achievements like the world's tallest skyscraper, officials sought to break another record by creating the largest fireworks show.
The Dubai skyline was a canvas for a dazzling 30-minute show. The display capped off with six minutes of fireworks that engulfed the city's man-made, palm-shaped island, with its fronds and trunk shimmering in thousands of lights. Organizers had promised that the fireworks would form a flying falcon, a sunrise and the United Arab Emirates flag.
In Ukraine, anti-government protesters hoped to set their own record for the most people to sing a national anthem at the same time. On Kiev's main square, at least 100,000 Ukrainians sang their national anthem in a sign of support for integration with Europe. The square has been the scene of massive pro-European protests for more than a month, triggered by President Viktor Yanukovych's decision to ditch a key deal with the European Union.

"Many here are welcoming the new year after losing their mothers, fathers, siblings and children so you can imagine how it feels," said village chief Maria Rosario Bactol of the Anibong community in Tacloban, the city worst hit by Typhoon Haiyan.

In Tokyo, five priests at the Zojoji temple used ropes to swing a wooden pole against a large bell, sounding the first of 108 gongs to mark the new year. Simultaneously, "2014" lit up in white lights on the modern Tokyo Tower in the background.
Juji Muto said he was curious to hear how the bell sounded. The 75-year-old retiree said he wishes every year for good health.
China had light shows at part of the Great Wall near Beijing and at the Bund waterfront in Shanghai. The city of Wuhan in central Hubei province called off its fireworks show and banned fireworks downtown to avoid worsening its smog.
Pope Francis used his year-end prayer service of thanksgiving to urge people to ask themselves: Did they spend 2013 to further their own interests or to help others?
The pontiff asked people to reflect if they used the past year to make the places where they live more livable and welcoming. Citing Rome as an example, Francis said the city is full of tourists, but also refugees.
