climate change

The 2023-24 El Niño is described as record-shattering, with analysis of its wide-ranging effects on global temperatures, weather patterns and ecosystems. The event has driven exceptional ocean warming in the tropical Pacific, contributing to record global heat, shifts in rainfall, droughts and flooding in various regions, and stress on fisheries and agriculture. Commentators are weighing how much of the recent temperature surge should be attributed to El Niño versus longer-term climate change.

UN Secretary-General António Guterres used his final address to the UN General Assembly to warn that superpowers alone cannot solve the world's problems, touching on climate change and global cooperation. The speech, covered by The Guardian, is being shared widely as it marks the end of his tenure and delivers a pointed message to major powers about shared responsibility.

The United Nations has declared that solving climate change is a 'decisive test of global solidarity', framing collective action on emissions and adaptation as the defining challenge for international cooperation. The statement underscores growing pressure on governments to deliver coordinated commitments, with the UN urging countries to set aside divisions and treat the climate crisis as a shared responsibility requiring joint effort.

Leaders of Pacific island nations used their addresses at the UN General Assembly to highlight the existential threats climate change poses to their countries, including rising sea levels and extreme weather. They urged the international community to take stronger action on emissions and to support vulnerable states facing displacement and loss of land.

World leaders, citing climate change as an existential threat, are demanding that the United Nations function effectively on the issue. The call reflects frustration among governments over stalled international climate action and the UN's struggles to deliver coordinated global responses to warming, extreme weather and rising sea levels affecting member states.

Island nations facing severe impacts from climate change say they are not giving up the fight, continuing to press for action despite mounting threats such as rising seas and extreme weather. Their representatives emphasize resilience and ongoing advocacy on the global stage.

Scientists are developing new ways to control mosquitoes, the animal that kills more people than any other on Earth. As the climate warms, mosquito seasons are growing longer, giving the insects more time to spread dangerous diseases such as malaria and dengue. Reports highlight how extended warm periods are expanding the threat to new regions and prompting research into novel control methods.

Supreme Court Justice Samuel Alito will no longer take part in a pending dispute over climate change, according to SCOTUSblog. His withdrawal from the case removes one vote from the panel that will decide the matter, and comes as the Court weighs its docket on major environmental and regulatory questions.

USA Today reports that hurricane activity is behaving abnormally across two ocean basins, with conditions described as historically out of whack. The Atlantic and Pacific seasons have both deviated from typical patterns, prompting meteorologists and readers to question how climate change may be reshaping storm formation, timing, and intensity this year.

Supreme Court Justice Samuel Alito has recused himself from a major climate change case before the court. The recusal means only eight justices will weigh in on the outcome, raising the possibility of a 4-4 split that would leave a lower court ruling in place. Recusals by Supreme Court justices are rare and typically stem from conflicts of interest.

The UN's humanitarian chief has said preventing a third world war is now the organisation's top priority, pointing to militarised artificial intelligence and climate change as key risks. The remarks, reported by Caliber.Az, also referenced a proposed 'Board of Peace' as part of discussions on global governance and conflict prevention.

Flash floods have struck Nepal, and an expert says climate change is to blame. Rising temperatures are believed to intensify monsoon rainfall, making sudden floods more frequent and severe in the Himalayan region. The comments add to a wider debate about how a warming climate is driving extreme weather disasters across South Asia.

New analysis indicates the global heatwave season has expanded by roughly 39 days, with extreme heat now arriving earlier in the year and lasting longer than before. Researchers attribute the lengthening season to warming temperatures, warning that prolonged exposure raises health risks and strains infrastructure. Coverage highlights how gradual change can go unnoticed even as extreme heat events become more frequent and severe.

US Supreme Court Justice Samuel Alito has recused himself from a major climate-change case just days before it was set to be heard, according to the New York Times. The decision removes one justice from a closely watched dispute over climate policy, raising questions about how the remaining eight justices might divide and why the recusal came so late.

The Trump administration is moving to roll back fuel economy standards for automakers, loosening federal requirements on vehicle efficiency. The change would give car manufacturers more flexibility but is likely to draw criticism from environmental groups and states that back stricter emissions rules. Details on the scope and timing of the rollback remain limited.

Le Monde examines how climate change is pushing people, planners and governments to reconsider where and how they live. As heatwaves, floods and rising seas make some areas less habitable, questions about relocating, adapting cities and rebuilding our relationship with the surrounding environment are moving from the margins to the centre of public debate.

The Trump administration has moved to roll back US fuel economy standards, loosening requirements on how efficient cars and light trucks must be. The change, reported by Spectrum News, is expected to benefit automakers by easing compliance costs, while critics warn it will increase gasoline consumption and greenhouse gas emissions. The rollback reverses stricter efficiency rules put in place under previous administrations.

The Trump administration has finalized its reversal of US fuel economy standards, undoing stricter efficiency requirements for cars and light trucks introduced under the previous administration. The move, reported by France 24, is expected to allow automakers to sell less efficient vehicles, drawing criticism from environmental groups and praise from industry, and could reshape the US auto market and emissions trajectory.

Thousands of people marched in cities across France to demand stronger action on climate change. One demonstrator summed up the mood, saying she wished more people had turned out 'after the summer we've just had', a reference to recent heatwaves and extreme weather. Organisers and participants are pressing the French government for more ambitious emissions reductions and adaptation measures.

President Donald Trump announced that he approved new fuel economy standards that would end what he calls the Biden administration's electric vehicle mandate. The move relaxes requirements pushing automakers toward EV production, and it is being widely reported by major outlets including Reuters. The change is expected to affect carmakers' plans and renew debate over federal climate and transportation policy.
