Pakistan's army and civil authorities are planning to evacuate 80,000 people to safety along the country's southern coast, and thousands in neighboring India sought shelter ahead of Cyclone Biparjoy, officials said Tuesday.

The cyclone is forecast to slam ashore in the densely populated region on Thursday. It is likely to be the most powerful to hit western India and Pakistan since 2021, and follows devastating floods that ravaged Pakistan last year, leaving 1,739 people dead and causing $30 billion in losses.

The United Nations has secured an insurance coverage to start a ship-to-ship transfer of 1.1 million barrels of crude from a rusting tanker moored off the coast of war-torn Yemen — oil that could cause a major environmental disaster.

The United Nations Development Program described the insurance is "a pivotal milestone" in a yearslong effort to evacuate the cargo of the FSO Safer, which is at risk of rupture or exploding.

A growing number of companies are pledging to cut their greenhouse gas emissions to " net zero " as part of global efforts to tackle climate change, but that goal is rarely supported by a credible plan, according to a report published Monday.

The idea behind net zero is to stop adding planet-warming gas to the atmosphere, either by preventing the emissions in the first place or removing an equivalent amount through natural or technological means. Scientists say the world needs to reach net-zero emissions by 2050 to limit global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) compared with pre-industrial times.

The destruction of the Kakhovka Dam was a fast-moving disaster that is swiftly evolving into a long-term environmental catastrophe affecting drinking water, food supplies and ecosystems reaching into the Black Sea.

The short-term dangers can be seen from outer space — tens of thousands of parcels of land flooded, and more to come. Experts say the long-term consequences will be generational.

The Philippines' most active volcano was gently spewing lava down its slopes Monday, alerting tens of thousands of people they may have to quickly flee a violent and life-threatening explosion.

More than 12,600 people have left the mostly poor farming communities within a 6-kilometer (3.7-mile) radius of Mayon Volcano's crater in mandatory evacuations since volcanic activity increased last week. But thousands more remain within the permanent danger zone below Mayon, an area long declared off-limits to people but where generations have lived and farmed because they have nowhere else to go.

President Joe Biden has called the smoke from Canadian wildfires in the eastern U.S. "another stark reminder of the impacts of climate change" and said cabinet officials are monitoring the impact on travel and air quality.

More than 600 firefighters and other personnel from the U.S. have been deployed to Canada to respond to the wildfires there, Biden said in a statement Thursday, adding that he offered additional help to Canadian Prime Minister Justin Trudeau.

Swedish environmental activist Greta Thunberg said Friday she will no longer be able to skip classes as a way to draw attention to climate change because she is graduating from high school.

Thunberg, 20, started staging Friday protests outside the Swedish parliament building during school hours in 2018. Teenagers from around the world followed her lead, leading to an international student movement called Fridays for Future.

On a boat off the coast of an island near Abu Dhabi, marine scientist Hamad al-Jailani feels the corals, picked from the reef nursery and packed in a box of seawater, and studies them carefully, making sure they haven't lost their color.

The corals were once bleached. Now they're big, healthy and ready to be moved back to their original reefs in the hope they'll thrive once more.

Philippine troops, police and rescue workers began forcibly evacuating residents near Mayon Volcano on Friday as its increasing unrest indicated a violent eruption of one of the country's most active volcanoes is possible within weeks or days.

The area within a 6-kilometer (3.7-mile) radius of Mayon's crater is supposed to be off-limits due to possible volcanic emissions, lava flows, rockfalls and other hazards. But many poor villagers have built houses and tended farms in Mayon's danger zone over the years.

Kilauea, one of the most active volcanoes in the world, began erupting on Wednesday after a three-month pause, displaying spectacular fountains of mesmerizing, glowing lava that's a safe distance from people and structures in a national park on the Big Island.

A glow was detected in webcam images from Kilauea's summit early in the morning, indicating that an eruption was occurring within the Halemaumau crater in the summit caldera, the U.S. Geological Survey's Hawaiian Volcano Observatory said.
