Meteorologists report that this year's El Niño is on track to be the strongest ever recorded, surpassing previous events in measured ocean temperatures in the tropical Pacific. Scientists warn the event could offer a preview of conditions typical of a warmer climate future, with potential for extreme weather worldwide. The warning comes as global temperatures have already been breaking records throughout the event.

Scientists are developing new methods to control mosquitoes as climate change lengthens mosquito season and expands the range of disease-carrying species. The mosquito kills more people than any other animal on earth, spreading diseases such as malaria and dengue, and longer warm seasons give the insects more time to transmit dangerous illnesses. Climate researchers warn the public health threat is growing.

Thousands of people took to the streets in cities across France to demand stronger action on climate change. Organisers and participants expressed disappointment at the turnout, with one marcher saying she wished more people had joined given the extreme summer the country has just experienced. The demonstrations add to ongoing pressure on the French government over its environmental policies.

The Economist examines how climate change is becoming a core national security concern, as rising temperatures, extreme weather and resource pressures strain militaries, borders and governments worldwide. The argument is that defense planning can no longer treat climate as a distant environmental issue but as an immediate driver of conflict, migration and instability that security institutions must prepare for.

The Trump administration has moved to roll back fuel economy standards for cars that were put in place under President Biden. The rollback relaxes emissions and efficiency requirements imposed on automakers, reversing a central pillar of the previous administration's climate policy. The change is likely to reignite debate over vehicle pollution rules and their impact on car prices, energy use and US climate commitments.

Palau's president addressed the United Nations General Assembly, highlighting climate change and rising global tensions. The address underscores the existential threat rising seas pose to low-lying Pacific island nations like Palau, which have limited influence individually but punch above their weight in climate diplomacy. The speech called for stronger international action amid widening geopolitical divisions that have slowed cooperation on global warming.

President Trump announced that his administration has ended an electric vehicle rule introduced under Joe Biden and has updated federal fuel economy standards. The move signals a continued rollback of Biden-era climate and emissions policies affecting automakers. Commentary is focused on what the changes mean for the US auto industry, consumers and the country's climate commitments.

PBS NewsHour reports on scientists developing new ways to control mosquito populations as rising global temperatures expand the habitats where the insects and the diseases they carry can spread. The segment examines research approaches to targeting mosquitoes as warming climate conditions push the public health threat into previously unaffected regions.

World Rivers Day is drawing attention to the worsening state of the world's rivers, many of which are shrinking, drying up or suffering from pollution and overuse. Coverage focuses on why rivers are 'running on empty', pointing to climate change, drought, damming and excessive water extraction as pressures leaving major waterways depleted and ecosystems at risk.

A Charlotte Observer opinion piece urges readers to remember Hurricane Helene and to acknowledge climate change as a factor in such disasters, regardless of political affiliation. The column argues that recognizing the link between warming temperatures and extreme weather should not be a partisan issue, as communities affected by the hurricane continue to recover.

A new study finds that climate change-driven evaporation made Ireland's record July drought eight times more likely than it would have been in a pre-industrial climate. The finding highlights how warming conditions intensify drought risk even in typically wet countries like Ireland, adding to growing scientific evidence that human-caused climate change is reshaping weather extremes across Europe.

New reporting suggests India has appeared to warm more slowly than much of the rest of the world, but this apparent reprieve may not be real. Aerosol pollution particles and cloud cover could be masking the true extent of warming over the country, reflecting sunlight and artificially suppressing recorded temperatures. If so, India could face a sudden and severe catch-up in heat as air quality improves, with serious implications for its population and agriculture.

Climate activist Greta Thunberg and the group Aurora have filed a new lawsuit against Sweden, arguing the state has failed to protect children from the consequences of climate change. The legal action follows earlier attempts to hold the Swedish government accountable through the courts, and renews pressure on policymakers over the country's climate commitments.

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.

The Trump administration is seeking to prevent the restoration of climate change and diversity-related information at US historical sites. The move suggests an effort to keep such material removed from exhibits or signage at federally maintained locations. The news has drawn attention amid broader debates over how climate science and diversity topics are handled across government institutions.

Some television meteorologists are working climate change into their weather forecasts, a shift that has drawn resistance from parts of their audiences. The CBC reports that broadcasters who connect daily weather to longer-term climate trends are encountering viewers who do not want to hear it. The debate highlights the growing role of on-air weather presenters as a trusted bridge between scientific research and the public.

Winemakers worldwide are adopting new strategies to cope with climate change, as rising temperatures and extreme weather disrupt grape growing. Reported approaches include shifting to more resilient grape varieties, moving vineyards to cooler regions and higher elevations, adjusting harvesting times, and using new vineyard techniques to protect vines from heat and drought.

The New York Times reports that the Trump administration is moving to roll back fuel economy standards for cars, easing emissions and efficiency requirements for automakers. The change would reverse stricter rules adopted under previous policy and is likely to draw criticism from climate advocates and praise from the auto industry. Details of the proposal and its scope are being discussed as the story circulates.

Scientists report that dust levels in Earth's atmosphere have declined, reversing a long-running trend. The shift is described as mysterious because its cause is not yet understood. Dust in the atmosphere affects climate, air quality and ocean ecosystems, so the change could have far-reaching implications for climate modeling.

The US government is moving to simplify environmental reviews for natural gas projects, a step officials describe as making project development easier. The change could speed up permitting for pipelines, terminals and other gas infrastructure, cutting the time and paperwork developers face. Environmental groups are likely to object that weaker reviews raise risks to air, water and affected communities.

High-level meetings have been held on measures to address climate change and ensure a fair transition, according to a government announcement from Kyrgyzstan's e-government portal. The discussions focus on policy steps to curb climate impacts while protecting workers and communities during the shift to a greener economy. Details of specific commitments or outcomes have not yet been made public.

New research from the University of Arizona analysing decades of satellite imagery finds that the world's drylands, though greening as vegetation responds to rising carbon dioxide, are increasingly locked into extreme 'boom-and-bust' cycles — rapid plant growth followed by sudden collapses. Scientists warn the pattern could destabilise ecosystems and the communities that depend on them.

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.
