The U.N. weather agency said Thursday that 2023 is all but certain to be the hottest year on record, and warning of worrying trends that suggest increasing floods, wildfires, glacier melt, and heat waves in the future.

The World Meteorological Organization also warned that the average temperature for the year is up some 1.4 degrees Celsius (2.5 degrees Fahrenheit) from pre-industrial times – a mere one-tenth of a degree under a target limit for the end of the century as laid out by the Paris climate accord in 2015.

Forty-one construction workers emerged dazed and smiling late Tuesday from a collapsed tunnel where they had been stranded the last 17 days — a happy ending to an ordeal that had gripped India and involved a massive rescue operation that overcame several setbacks.

Locals, relatives and government officials erupted in joy, set off firecrackers and shouted "Bharat Mata ki Jai" — Hindi for "Long live mother India" — as happy workers walked out after receiving a brief checkup by doctors. Officials hung garlands around their necks as the crowd cheered.

The world is heading for considerably less warming than projected a decade ago, but that good news is overwhelmed by much more pain from current climate change than scientists anticipated, experts said.

That's just one of a set of seemingly contradictory conditions facing climate negotiators who this week gather in Dubai for marathon United Nations talks that include a first-ever assessment of how well the world is doing in its battle against global warming. It's also a conference where one of the central topics will be whether fossil fuels should be phased out, but it will be run by the CEO of an oil company.

The Emirati president-designate for the upcoming United Nations COP28 climate talks forcefully denied Wednesday a report alleging his nation planned to use the summit to strike oil and gas deals, a day before the summit was due to begin.

Sultan al-Jaber, who also leads the massive state-run Abu Dhabi National Oil Co., called the allegations from a BBC report "an attempt to undermine the work of the COP28 presidency" before the talks begin Thursday. The report cited what it described as "leaked briefing documents" the broadcaster said showed the Emirates planned to discuss fossil fuel deals with 15 nations.

National and regional authorities in Spain signed an agreement Monday to invest 1.4 billion euros ($1.5 billion) in areas around the treasured national park of Doñana in a bid to stop the park from drying up.

Ecological Transition Minister Teresa Ribera said the plan was aimed at encouraging farmers to stop cultivating crops that rely heavily on water from underground aquifers that have been overexploited in recent years, damaging one of Europe's largest wetlands.

Tornadoes were forecast for the Black Sea region on Tuesday, a day after a storm that left more than 2 million people without electricity in Crimea, Russia and Ukraine. A think tank said that the weather also impacted Russian military operations.

The storm killed at least 14 people in Russia and Ukraine officials said as it toppled trees, tore down power lines and flooded coastal areas.

Dubai prepared to host the COP28 climate talks Tuesday as world leaders including U.S. President Joe Biden signaled they would not be attending the negotiations that come during the ongoing Israel-Hamas war roiling the wider Middle East.

Workers under a still-scorching November sun stapled up bunting and decorated Dubai Expo City's iconic Al Wasl Dome with trees and other green foliage ahead of the summit, scheduled to start Thursday in the United Arab Emirates.

Authorities recovered the body of an 11-year-old girl Saturday evening from the debris of a landslide in southeast Alaska that tore down a wooded mountainside days earlier, smashing into homes in a remote fishing village.

The girl, Kara Heller, was the fourth person confirmed killed by last Monday night's landslide.

Amid record-high temperatures, deluges, droughts and wildfires, leaders are convening for another round of United Nations climate talks later this month that seek to curb a centuries-long trend of humans spewing ever more greenhouse gases into the atmosphere.

For hundreds of years, people have shaped the world around them for their benefit: They drained lakes, deforested lands and mined for metals and minerals to grow wealth and economies. They dug up billions of tons of coal, and then oil and gas, to fuel empires and economies. The allure of exploiting nature and burning fossil fuels as a path to prosperity hopped from nation to nation, each eager to secure their own cheap energy. Over hundreds of years, that impulse has remade the planet's climate, too — and brought its inhabitants to the brink of catastrophe.

More than half a million people were left without power in Crimea, Russia and Ukraine after a storm in the Black Sea area flooded roads, ripped up trees and took down power lines, Russian state news agency Tass and Ukraine's energy ministry said. Meanwhile, the Moscow region experienced its heaviest snowfall in 40 years, the governor said.

The storms and snowfall were part of a weather front that left one person dead and many places without electricity amid heavy snow and blizzards in Romania and Moldova on Sunday.
