U.N. member states on Monday open two weeks of negotiations aimed at finally reaching a treaty meant to protect and preserve vast areas of the world's oceans.

Conspiracy theories about a U.S. research station have resurged, with social media users falsely blaming it for the Turkey-Syria earthquakes, following debunked claims it causes weather disasters and spreads the coronavirus.

Appearing at a glance to be just a simple pleasure boat floating on the San Francisco Bay, as the hydrofoil-equipped vessel picks up speed it suddenly begins rising above the water, grabbing the attention of passengers on a nearby ferry.

World Athletics president Sebastian Coe said Friday long-distance events could be "decoupled" from major championships due to climate change as concerns mount about competitor welfare in soaring heat.    

A pet leopard escaped from a house in the Pakistan capital and roamed the streets for hours before being shot with a sedation dart, wildlife officials said Friday.

A desert bloom triggered by heavier than usual winter rains has carpeted the sands of northern Saudi Arabia with purple flowers, drawing sightseers from across the Arabian Peninsula.

Climate change isn't causing the multi-year drought that is devastating parts of Argentina, Uruguay, Brazil and Bolivia, but warming is worsening some of the dry spell's impacts, a new study says.

The natural three-year climate condition La Nina – a cooling of the central Pacific that changes weather worldwide temporarily but lasted much longer than normal this time – is the chief culprit in a drought that has devastated central South America and is still going on, according to a flash study released Thursday by international scientists at World Weather Attribution. The study has not been peer reviewed yet.

Scientists got their first up-close look at what's eating away part of Antarctica's Thwaites ice shelf, nicknamed the Doomsday Glacier because of its massive melt and sea rise potential, and it's both good and bad news.

Using a 13-foot pencil-shaped robot that swam under the grounding line where ice first juts over the sea, scientists saw a shimmery critical point in Thwaites' chaotic breakup, "where it's melting so quickly there, there's just material streaming out of the glacier," said robot creator and polar scientist Britney Schmidt of Cornell University.

Weeks after powerful storms dumped 32 trillion gallons of rain and snow on California, state officials and environmental groups in the drought-ravaged state are grappling with what to do with all of that water.

State rules say when it rains and snows a lot in California, much of that water must stay in the rivers to act as a conveyer belt to carry tens of thousands of endangered baby salmon into the Pacific Ocean.

The United Nations chief has warned that global sea levels have risen faster since 1900 and their relentless increase puts countries like Bangladesh, China, India and the Netherlands at risk and acutely endangers nearly 900 million people living in low-lying coastal areas.

In a grim speech to the Security Council's first-ever meeting on the threat to international peace and security from rising sea levels, Secretary-General Antonio Guterres declared that sea levels will rise significantly even if global warming is "miraculously" limited to 1.5 degrees Celsius (2.7 degrees Fahrenheit), the elusive international goal.
