More than 30,000 residents of Sydney and its surrounds were told to evacuate or prepare to abandon their homes Monday as Australia's largest city faces its fourth, and possibly worst, round of flooding in less than a year and a half.

Days of torrential rain caused dams to overflow and waterways to break their banks, bringing a new flood emergency to parts of the city of 5 million people.

A fourth crew member has been rescued Monday after a storm sunk an engineering vessel two days earlier, according to Chinese authorities.

The crew member was rescued by a navy ship Monday morning and is in stable condition, according to a statement by Guangdong maritime authorities. Rescue work is still ongoing.

The United Nations said Thursday's U.S. Supreme Court ruling that curbs regulators' power to limit greenhouse gas emissions had dealt a blow to the fight against global warming.

On a bright moonlit night, a team of scientists and volunteers head out to a protected beach along the Delaware Bay to survey horseshoe crabs that spawn in their millions along the U.S. East Coast from late spring to early summer.

More than 500 days into his presidency, Joe Biden's hope for saving the Earth from the most devastating effects of climate change may not quite be dead.

But it's not far from it.

India banned some single-use or disposable plastic products Friday as part of a federal plan to phase out the ubiquitous material in the nation of nearly 1.4 billion people.

For the first stage, it has identified 19 plastic items that aren't very useful but have a high potential to become litter and makes it illegal to produce, import, stock, distribute or sell them. These items range from plastic cups and straws to ice cream sticks. Some disposable plastic bags will also be phased out and replaced with thicker ones.

The combination of heat and humidity would have quickly created life-threatening conditions inside the packed, un-air-conditioned tractor-trailer where dozens of immigrants were found dead, an expert said.

Although it's unclear how long the people had been inside the trailer, it likely would only take an hour or less for temperatures to climb as high as 125 degrees (51 Celsius) or hotter, said Jennifer Vanos, an assistant professor in climate and health at Arizona State University who has studied child deaths in cars.

Pounding rain following weeks of heavy downpours triggered a mudslide in northeast India that killed at least 14 people and left more than 30 others missing, authorities said Thursday.

Disaster response workers, police and local villagers were trying to rescue those buried under the debris in Noney, a town near Imphal, the capital of Manipur state.

Amos Hochstein, President Joe Biden's point man for global energy problems, says he knows that transitioning away from the climate-wrecking pollution of fossil fuels is the only way to go. He advocates urgently for renewable energy, for energy-smart thermostats and heat pumps.

But when it comes to tackling the pressing energy challenges presented by Russia's war on Ukraine, Hochstein also can sound like nothing as much as the West's oilfield roustabout, taking a giant pipe wrench to the world's near-crisis-level energy shortfalls.

Australia's new government is putting climate change at the top of its legislative agenda when Parliament sits next month for the first time since the May 21 election, with bills to enshrine a cut in greenhouse gas emissions and make electric cars cheaper, a minister said on Wednesday.

A bill will be introduced to commit Australia to reducing its emissions by 43% below 2005 levels by 2030 when Parliament sits on July 26, Minister for Climate Change and Energy Chris Bowen told the National Press Club.
