World prepares to ring in 2024

Jubilant crowds will bid farewell to the hottest year on record Sunday, closing a turbulent 12 months marked by clever chatbots, climate crises, and wrenching wars in Gaza and Ukraine.

The world's population — now over eight billion — will see out the old and usher in the new, with many hoping to shake the weight of high living costs and global tumult.

In Sydney, the self-proclaimed "New Year's capital of the world", more than a million partygoers are expected to pack the city's foreshore, despite uncharacteristically dank weather.

Eight tons of fireworks will light the fuse in 2024, a year that will bring elections concerning half the world's population and a summer Olympiad celebrated in Paris.

The last 12 months brought "Barbiegeddon" at the box office, a proliferation of human-seeming artificial intelligence tools, and a world-first whole-eye transplant.

India outgrew China as the world's most populous country and then became the first nation to land a rocket on the dark side of the moon.

It was also the hottest year since records began in 1880, with a spate of climate-fuelled disasters striking from Australia to the Horn of Africa and the Amazon basin.

Perhaps more than anything, 2023 will be remembered for Hamas's October 7 assault on southern Israel — and Israel's ferocious reprisals.

Rebuilding

The United Nations estimates that almost two million Gaza residents have been displaced since Israel's siege began — about 85 percent of the peacetime population.

With once-bustling Gaza City neighborhoods reduced to rubble, there were few places left to mark the new year — and fewer loved ones to celebrate with.

"It was a black year full of tragedies," said Abed Akkawi, who fled the city with his wife and three children. 

The 37-year-old, now living in a UN shelter in Rafah, southern Gaza, said the war had obliterated his house and killed his brother.

But still, he clings to modest hopes for 2024.

"God willing this war will end, the new year will be a better one, and we will be able to return to our homes and rebuild them, or even live in a tent on the rubble," he told AFP.   

In Ukraine, where Russia's invasion grinds towards its second anniversary, there was defiance and hope in the face of a renewed assault from Moscow.

"Victory! We are waiting for it and believe that Ukraine will win," said Tetiana Shostka as air raid sirens blared in Kyiv.

"We will have everything we want if Ukraine is free, without Russia," the 42-year-old added.

Some in Vladimir Putin's Russia are also weary of the conflict.

"In the new year, I would like the war to end, a new president, and a return to normal life," said 55-year-old theatre decorator and Moscow resident Zoya Karpova.

Putin is already his country's longest-tenured leader since Joseph Stalin and his name will again be on the ballot paper when Russians vote in March.

Few expect the vote to be fully free or fair, or for the former KGB man to return to the shadows.

To the polls

Russia's is just one of several pivotal elections scheduled, with 2024 looming as the year of the ballots. 

In all, the political fate of more than four billion people will be decided in contests that could reshape Britain, France, India, Indonesia, Mexico, South Africa, Venezuela and a host of other nations.

But one election promises consequences for the entire world. In the United States, Democrat Joe Biden, aged 81, and Republican Donald Trump, aged 77, appear set to rerun their divisive 2020 election race this November.

As the incumbent, Biden has at times appeared to show his advancing age and even his supporters worry about the toll of another bruising four years in office.

But if there are worries about what a second Biden administration would look like, there are at least as many concerns about a return of Trump, who faces prosecution on several counts.

Voters could yet decide whether the bombastic self-proclaimed billionaire goes to the Oval Office or jail.
