There are easier ways to cross an ocean, but few are as slick or stylish as the remora's whale-surfing joyride.

Scientists tracking humpbacks off the coast of Australia have captured rare footage that shows clutches of the freeloading fish peeling away from their host in what looks like a high-speed game of chicken, just moments before the whale breaches.

The world has changed dramatically in the decade since leaders celebrated a historic climate agreement in Paris a decade ago, but not quite in ways they expected or wanted.

Earth's warming climate has gotten nastier faster than society has been able to wean itself from burning the coal, oil and natural gas that emits carbon pollution that triggers global warming, several scientists and officials said.

A thick layer of smog enveloped India's capital Monday, filling the air with an acrid smell as pollution levels surged and worsening a public health crisis that has prompted its residents to take the streets to protest and demand government action.

By Monday morning, New Delhi's air quality index stood at 344, a level considered "severe" and dangerous to breathe, according to the World Health Organization's recommended exposure limits.

Typhoon Fung-wong blew out of the northwestern Philippines on Monday after setting off floods and landslides, knocking out power to entire provinces, killing at least four people and displacing more than 1.4 million others.

It was forecast to head northwest toward Taiwan.

U.N. climate negotiations were expected to begin Monday at a meeting on the edge of the Brazilian Amazon, with leaders pushing for urgency, cooperation and acceleration after more than 30 years fighting to curb global warming by drastically reducing the carbon pollution that causes it.

André Corrêa do Lago, president of this year's conference, known as COP30, emphasized that negotiators engage in "mutirão," a Brazilian word derived from an Indigenous word that refers to a group uniting to work on a shared task.

Typhoon Kalmaegi has killed at least 114 people in the Philippines with even more missing and then hit Vietnam Friday. A second typhoon, Fong-Wong, is forecast to hit the Philippines around Sunday and strengthen to a major storm by that time.

Some facts about typhoons:

Brazil on Thursday unveiled long-awaited details of a plan to pay countries to preserve their tropical forests and announced it had already drawn $5.5 billion in pledges.

The fund is President Luiz Inácio Lula da Silva's flagship project as he welcomes world leaders to the edge of the Amazon for the United Nations annual climate summit — an effort to draw attention and money to the imperiled rainforest crucial to curbing global warming.

World leaders warned Thursday that time is running short for urgent and decisive action to prevent the worst effects of climate change, and blasted the United States for its retreat from those efforts, as they gathered at the edge of Brazil's Amazon rainforest for the annual United Nations climate summit.

U.N. Secretary-General António Guterres opened a gathering of heads of state in Belem, Brazil, with harsh words for world powers who he said "remain captive to the fossil fuel interests, rather than protecting the public interest."

Typhoon Kalmaegi brought fierce winds and torrential rains to Vietnam on Friday, killing at least five people, flattening homes, blowing off roofs and uprooting trees. In the Philippines, where the storm left scores dead earlier in the week, survivors wept over the coffins of their loved ones and braced for another typhoon.

As the storm moved on, recovery work began in battered towns and villages in both countries. Across central Vietnamese provinces, people cleared debris and repaired roofs on their homes.

Philippine President Ferdinand Marcos Jr. declared a state of emergency on Thursday after Typhoon Kalmaegi left at least 114 people dead and more than 100 missing in central provinces in the deadliest natural disaster to hit the country this year.

The deaths were mostly from drowning in flash floods and 127 people were still missing, many in the hard-hit central province of Cebu. The tropical cyclone blew out of the archipelago on Wednesday into the South China Sea.
