An international effort to improve air quality by requiring ships to use less-polluting fuel caused a spike in global warming, according to research published Thursday on this unintended climate "shock".

Global shipping's switch to low-sulphur fuels starting in 2020 "could lead to a doubling (or more) of the warming rate" this decade and has already contributed to record-breaking heat over the past year, the study said.

An Indian court has urged the government to declare a national emergency over the country's ongoing heatwave, saying that hundreds of people had died during weeks of extreme weather.

Rays of sunlight slice through pools of crystal water as clusters of fish cast shadows on the limestone below. Arching over the emerald basin are walls of stalactites dripping down the cavern ceiling, which opens to a dense jungle.

These glowing sinkhole lakes — known as cenotes — are a part of one of Mexico's natural wonders: A fragile system of an estimated 10,000 subterranean caverns, rivers and lakes that wind almost surreptitiously beneath Mexico's southern Yucatan peninsula.

Consumers' love for avocados in the United States seems to know no bounds. From 2001 through 2020, consumption of this fruit laden with healthy fats tripled nationwide, rising to over 8 pounds per person yearly.

On average, 90% of those avocados are grown in the southwest Mexican state of Michoacán. As with other foods that have become trendy, such as acai berries, or widely used, such as palm oil, intensive avocado production is causing significant environmental damage.

Traumatized survivors of the massive landslide estimated to have buried hundreds in Papua New Guinea have been slow to move to safer ground as the South Pacific island nation's authorities prepare to use heavy machinery to clear debris and risk triggering another landslide, officials said Thursday.

Government and army geotechnical experts on Thursday were examining the stability of the massive swath of rubble that crushed Yambali village when a mountainside collapsed last week, Enga provincial administrator Sandis Tsaka said. Australian and New Zealand experts were expected to arrive on Friday.

About 6.5 million children in Afghanistan were forecast to experience crisis levels of hunger in 2024, nongovernmental organization Save the Children said.

Nearly 3 of 10 Afghan children will face crisis or emergency levels of hunger this year as the country feels the immediate impacts of floods, the long-term effects of drought, and the return of Afghans from neighboring Pakistan and Iran, according to a report released late Tuesday by Save The Children.

Power outages remained widespread Wednesday in storm-weary Texas a day after another burst of severe weather flooded streets, uprooted trees and ripped off roofs. Authorities said a teenager was killed at a construction site while working on a home that collapsed.

The severe weather Tuesday, which at one point left more than 1 million customers without electricity, was a continuation of deadly storms, some spawning tornadoes, across the U.S. over the long Memorial Day weekend that killed 24 people in seven states.

At the rear of Rio de Janeiro's polluted Guanabara Bay, thousands of mangroves rise as tall as 13 feet (about 4 meters) from a previously deforested area.

The 30,000 trees, planted by non-profit organization Instituto Mar Urbano over four years in the Guapimirim environmental protection area, stand as an example for cities seeking natural means to improve climate resilience.

All Spix's macaws are majestically blue in the blazing sun of Brazil's Northeast, but each bird is distinct to Candice and Cromwell Purchase. As the parrots soar squawking past their home, the couple can readily identify bird No. 17 by its smooth feathers and can tell No. 16 from No. 22, which has two beads attached to its radio collar.

This familiarity offers a glimpse of the South African couple's commitment to saving one of the world's most critically endangered species. The parrot — endemic to a small fraction of the Sao Francisco River basin and already rare in the 19th century — was declared extinct in the wild in 2000, when a lonely surviving male disappeared following decades of poaching and habitat destruction from livestock overgrazing. The few remaining birds were scattered in private collections around the world.

Aquaman might not mind if the oceans rise, but moviegoers might.

That's one of the takeaways from a new study conducted by researchers who set out to determine if today's Hollywood blockbusters are reflective of the current climate crisis. The vast majority of movies failed the "climate reality check" proposed by the authors, who surveyed 250 movies from 2013 to 2022.
