Warnings are circulating that a possible super El Nino event, amplified by global warming, could put as many as 450,000 lives at risk. The claim, highlighted in Marathi-language news coverage, links the intensifying El Nino pattern to deadly heatwaves, droughts and crop failures. Commenters are debating how far climate change is making these warming episodes stronger and more dangerous for vulnerable populations.

Donald Trump said he has approved new fuel economy standards that roll back rules put in place during Joe Biden's administration. The change relaxes efficiency requirements for cars and light trucks, a longstanding goal of Trump's deregulation agenda that automakers and environmental groups have been contesting. Reaction has focused on what the rollback means for gasoline prices, vehicle choices and US climate targets.

A study published in Science argues that a Mega El Niño pattern, producing extreme and prolonged climate swings, triggered the end-Permian mass extinction around 252 million years ago, the deadliest extinction event in Earth's history. The researchers say runaway warming destabilised ecosystems beyond what species could tolerate. The paper is being shared widely, with an open-access version of the full text available.

Island nations facing rising seas and intensifying storms say they will not abandon their fight against climate change, despite mounting setbacks. Leaders and residents of low-lying states are pressing for stronger global action on emissions and climate finance as their homelands face existential threats from warming oceans and coastal erosion.

The Trump administration has moved to roll back fuel economy standards for cars that were put in place under President Biden. The change would loosen requirements on automakers to improve vehicle efficiency, a signature climate policy of the previous administration. The move is expected to draw criticism from environmental groups and praise from parts of the auto industry.

Small island nations facing existential threats from rising seas and climate change are pressing the international community for stronger action, declaring 'we're not giving up.' The widely syndicated AP story frames these states as the moral voice of global climate negotiations, highlighting their activism despite limited power. The coverage is being picked up by outlets across the United States.

Al Jazeera is reporting that climate change is redrawing coastlines, warning that rising sea levels pose a growing threat to coastal cities around the world. The coverage highlights how flooding, erosion and land loss are expected to displace communities and strain infrastructure in low-lying urban areas as warming oceans continue to expand and ice sheets melt.

Italy's parliament has approved a law allowing the country to restart nuclear energy production, nearly four decades after a referendum banned it following the 1987 vote. The move marks a major shift in Italy's energy policy and opens the way for new nuclear projects. Reaction has focused on what it means for the country's energy supply and climate goals.

Winemakers worldwide are adopting new strategies to cope with climate change, which is altering growing seasons, harvest times and grape quality in traditional wine regions. Reported approaches include shifting to more resilient grape varieties, moving plantings to cooler altitudes and latitudes, changing vineyard management techniques and experimenting with new irrigation and shading methods. The story highlights how a sector closely tied to stable weather patterns is being forced to adapt its centuries-old practices.

Some television weather forecasters are working climate change into their broadcasts, explaining links between warming and extreme weather. CBC reports that while many meteorologists see it as part of their job, not all viewers welcome the added context, and some forecasters face criticism or complaints when they connect daily forecasts to longer-term climate trends.

Climate rallies are being organised across France following a summer of record-breaking heat. Demonstrators are expected to gather in multiple cities to demand stronger government action on climate change, after months in which temperature records were broken nationwide. The events highlight growing public pressure on French authorities over environmental policy and the country's response to increasingly extreme summer weather.

Singapore recorded its joint-highest daily maximum temperature for September after the Woodlands Avenue 9 climate station reached 35.8°C at 3.27pm on Saturday, 26 September. The reading ties the national September record and adds to growing concern over heat extremes affecting the island, with unusually hot late-September weather drawing wide attention.

The 63rd Session of the UN Human Rights Council in Geneva is putting environmental issues on its agenda, with the Geneva Environment Network highlighting how the environment features in this round of discussions. The session continues the Council's growing focus on the right to a healthy environment and the links between human rights and climate change, biodiversity loss and pollution.

The European Union's new rules banning greenwashing come into force on Sunday. The measures restrict companies from making unverified environmental claims about their products, such as vague labels like 'eco-friendly' or 'climate neutral' without proof. The change is aimed at giving consumers reliable information and holding businesses accountable for misleading sustainability marketing across the bloc.

Prime Minister Narendra Modi has inaugurated an international conference titled "The Future of Environment & Climate Dynamics," marking the opening of discussions among global participants on environmental and climate issues. The event is drawing attention as India highlights its role in international climate cooperation at a time of growing concern over extreme weather and environmental change.

President Trump is moving to lower federal fuel economy standards, rolling back efficiency requirements for cars and light trucks. The change would allow automakers to sell less fuel-efficient vehicles in the United States, reversing stricter rules adopted under previous administrations. Industry groups have long lobbied for weaker standards, while environmental advocates warn the move will increase gasoline consumption and emissions. Debate is expected ahead of the formal rulemaking process.

The Metropolitan Transportation Authority is repairing the Hudson Line as part of a wider effort to protect New York's transit network from climate change impacts. An amNewYork op-ed argues the work is one element of a broader strategy to prepare the system for flooding, storms and other extreme weather threats facing the region.

High Country News reporter Hannah Covington examines hail damage, a problem costing billions of dollars annually in the United States and one that could intensify as the climate warms. At a cold laboratory in Colorado, scientists are working to better understand how hailstones form so they can improve forecasting and reduce losses to crops, vehicles and buildings.

Scientists say America's fall foliage is shifting, with peak leaf-peeping colors arriving later and displays becoming less vibrant in some regions. Warmer temperatures and changing weather patterns are cited as key drivers affecting when and how leaves turn across the country.
