Coal-fired power plants would be forced to capture smokestack emissions or shut down under a rule issued by the U.S. Environmental Protection Agency.

New limits on greenhouse gas emissions from fossil fuel-fired electric plants are the Biden administration's most ambitious effort yet to roll back planet-warming pollution from the power sector, the nation's second-largest contributor to climate change. The rules are a key part of President Joe Biden's pledge to eliminate carbon pollution from the electricity sector by 2035 and economy-wide by 2050.

Flooding in Tanzania caused by weeks of heavy rain has killed 155 people and affected more than 200,000 others, the prime minister said.

That is more than double the number of deaths reported two weeks ago as the amount of rainfall increases, especially in the coastal region and the capital, Dar es Salaam.

Circumstantial evidence points to climate change as worsening the deadly deluge that just flooded Dubai and other parts of the Persian Gulf, but scientists didn't discover the definitive fingerprints of greenhouse gas-triggered warming they have seen in other extreme weather events, a new report found.

Between 10% and 40% more rain fell in just one day last week — killing at least two dozen people in the United Arab Emirates, Oman and parts of Saudi Arabia — than it would have in a world without the 1.2 degrees Celsius (2.2 degrees Fahrenheit) warming that has come from the burning of coal, oil and natural gas since the mid-19th century, scientists at World Weather Attribution said Thursday in a flash study that is too new to be peer-reviewed.

Just like the animals on Noah's Ark, the corals arrived in a pair.

On Monday, divers with gloved hands gently nestled the self-bred corals from the World Coral Conservatory project among their cousins in Europe's largest coral reef at the Burgers' Zoo in the Netherlands.

The world must agree this year on how to raise billions of dollars to help poorer countries adapt to global warming, the president of the U.N. climate talks said Thursday.

Mukhtar Babayev offered little concrete detail about how to broker this new deal but said climate finance would be a "pillar" of the COP29 summit in the petro-state of Azerbaijan in November.

When a small number of cases of locally transmitted malaria were found in the United States last year, it was a reminder that climate change is reviving or migrating the threat of some diseases. But across the African continent malaria has never left, killing or sickening millions of people.

Take Funmilayo Kotun, a 66-year-old resident of Makoko, an informal neighborhood in Nigeria's Lagos city. Its ponds of dirty water provide favorable breeding conditions for malaria-spreading mosquitoes. Kotun can't afford insecticide-treated bed nets that cost between $7 and $21 each, much less antimalarial medications or treatment.

Thousands of negotiators and observers representing most of the world's nations are gathering in the Canadian city of Ottawa this week to craft a treaty to stop the rapidly escalating problem of plastic pollution.

Each day, the equivalent of 2,000 garbage trucks full of plastic are dumped into the world's oceans, rivers and lakes, according to the United Nations Environment Programme. People are increasingly breathing, eating and drinking tiny plastic particles.

Skies over southern Greece turned an orange hue on Tuesday as dust clouds blown across the Mediterranean Sea from North Africa engulfed the Acropolis and other Athens landmarks.

Strong southerly winds carried the dust from the Sahara Desert, giving the atmosphere of the Greek capital a Martian-like filter in the last hours of daylight.

As a drought in Mexico drags on, angry subsistence farmers have begun taking direct action on thirsty avocado orchards and berry fields of commercial farms that are drying up streams in the mountains west of Mexico City.

Rivers and even whole lakes are disappearing in the once green and lush state of Michoacan, as the drought combines with a surge in the use of water for the country's lucrative export crops, led by avocados.
