Nearly 200 nations faced a Monday deadline to file what the United Nations' climate chief calls "among the most important policy documents governments will produce this century" — their plans on how they will cut emissions of heat-trapping gases.

Most won't make the deadline. The U.N. says that's OK as long as they are working on them.

The world warmed to yet another monthly heat record in January, despite an abnormally chilly United States, a cooling La Nina and predictions of a slightly less hot 2025, according to the European climate service Copernicus.

The surprising January heat record coincides with a new study by a climate science heavyweight, former top NASA scientist James Hansen, and others arguing that global warming is accelerating. It's a claim that's dividing the research community.

Using satellite trackers, scientists have discovered the whereabouts of young sea turtles during a key part of their lives.

"We've had massive data gaps about the early baby to toddler life stages of sea turtles," said Kate Mansfield, a marine scientist at the University of Central Florida. "This part of their long lives has been largely a mystery."

For nearly four years, India's government pushed an initiative to get people to think about how to make lifestyle choices that pollute less, like cycling instead of driving or using less plastic.

But in the country's yearly budget announcement last weekend, the once-flagship program failed to get a mention — or any promise of future funding.

Monsoon rains unleashed flooding in Australia's Queensland that have claimed the lives of two people as the week-long deluge dropped months of rainfall in a few days, devastating small rural towns on the state's north coast.

The body of an 82-year-old woman was found on Tuesday in a paddock near the North Queensland town of Ingham. It followed the death of a 63-year-old woman on Sunday when the rescue boat she was traveling in struck a tree and flipped.

A series of earthquakes near the Greek island of Santorini have led authorities to shut down schools, dispatch rescue teams with sniffer dogs and send instructions to residents including a request to drain their swimming pools.

Even though earthquake experts say the more than 200 tremors that have hit the area since early Friday are not related to the volcano in Santorini, which once produced one of the biggest eruptions in human history, locals are on edge.

India doubled its tiger population in a little over a decade by protecting the big cats from poaching and habitat loss, ensuring they have enough prey, reducing human-wildlife conflict, and increasing communities' living standards near tiger areas, a study published Thursday found.

The number of tigers grew from an estimated 1,706 tigers in 2010 to around 3,682 in 2022, according to estimates by the National Tiger Conservation Authority, making India home to roughly 75% of the global tiger population. The study found that some local communities near tiger habitats have also benefited from the increase in tigers because of the foot traffic and revenues brought in by ecotourism.

Sixteen environmental activists who were jailed for actions including stopping traffic, blocking an oil facility and splashing a van Gogh painting with soup went to a London court Wednesday to challenge their sentences.

The Just Stop Oil protesters say they received unduly harsh prison terms –- between 15 months and five years –- for disruptive but peaceful actions.

The Grammy Awards will look a little bit different this week.

Each year, the Recording Academy hosts a multitude of events to welcome the music industry during Grammy week and record labels do the same. However, many institutions have canceled their plans — Universal Music Group, Sony, Spotify, BMG and Warner Music Group among them — and instead are allocating resources to help those affected by the devastating Los Angeles-area wildfires.

Human-caused climate change increased the likelihood and intensity of the hot, dry and windy conditions that fanned the flames of the recent devastating Southern California wildfires, a scientific study found.

But the myriad of causes that go into the still smoldering fires are complex, so the level of global warming's fingerprints on weeks of burning appears relatively small compared to previous studies of killer heat waves, floods and droughts by the international team at World Weather Attribution. Tuesday's report, too rapid for peer-review yet, found global warming boosted the likelihood of high fire weather conditions in this month's fires by 35% and its intensity by 6%.
