New data indicates the current El Niño is the strongest ever measured, marking a major shift in global weather patterns. The development is drawing attention because a powerful El Niño typically brings droughts, floods and heat extremes to different regions worldwide, with scientists watching closely for effects on temperatures, agriculture and extreme weather in the months ahead.

Scientists are developing new methods 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 shifting temperatures are expanding the disease threat into new regions and prompting fresh research into targeting the insects.

The president of Palau addressed the United Nations General Assembly, highlighting climate change and growing global tensions. As leader of a small Pacific island nation highly vulnerable to rising seas, Palau has long used the UN platform to urge stronger international action on climate.

Viewers are drawn to the unusual perspective of a young person searching for hope amid the climate crisis.

A New York Times opinion piece argues that the emerging super El Niño, while expected to bring severe weather impacts worldwide, gives governments and communities valuable lead time to prepare. The author urges using the advance warning to strengthen defenses against likely heatwaves, droughts, floods and other disruptions linked to the climate pattern.

The City of Boulder's landmark climate liability lawsuit is heading to the United States Supreme Court, raising questions about who pays for climate damage. The case, brought against major fossil fuel companies, tests whether local governments can seek damages in state courts for climate-related costs. Observers are weighing what the outcome could mean for similar suits nationwide.

Climate discussions in New York are being reshaped by two mounting pressures: rising energy costs for households and industry, and the surging electricity demand from artificial intelligence data centres. As negotiators and business leaders weigh decarbonisation goals against affordability and grid reliability, the rapid growth of AI is complicating plans to phase out fossil fuels, forcing climate policy to account for a new wave of power consumption.

Thousands of people marched in cities across France to demand stronger climate action, with demonstrators saying the country's recent extreme summer should have drawn bigger crowds. One participant told reporters they wished more people had turned out 'after the summer we've just had'. The protests reflect growing public frustration in France over heatwaves and slow government responses to the climate crisis.

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.

Some television meteorologists are working climate change into their weather forecasts, a shift that has drawn resistance from parts of their audiences.

California has acquired 640 acres of land near Pioneertown in the Mojave Desert for the conservation of the western Joshua tree, whose habitat is threatened by climate change. The purchase reflects the state's broader effort to protect the iconic species, with climate projections suggesting shrinking suitable habitat across the region in the coming decades.

New research reported this week indicates that periods of climate change triggered rare, rapid bursts of evolutionary diversification in birds. The findings suggest that shifting environments repeatedly pushed bird lineages to adapt and split into new species, rather than evolving at a steady pace. Scientists say the work helps explain why bird diversity is distributed unevenly across the globe and how species may respond to today's warming climate.

Climate change is altering what ends up on plates at top restaurants, as shifting temperatures and weather patterns disrupt the supply of key ingredients. Chefs at acclaimed tasting-menu establishments are rethinking their signature dishes, swapping ingredients that have become scarce or unpredictable for locally available alternatives. The story highlights how fine dining is adapting its menus to reflect a changing natural environment.

WIRED argues that growing public and political resistance to data centers, driven by energy demands and local impacts, should be framed as a climate reckoning but so far is not. The piece contends the backlash focuses on siting and costs while missing the industry's broader carbon footprint, and urges climate to become central to the debate.

Bulgarian National Radio reports that night-time temperatures in Bulgaria have risen sharply over the past two decades. The finding points to warming that is most visible after dark, a pattern scientists link to climate change because it reduces nighttime cooling and puts additional strain on health, agriculture and energy use. The report is drawing attention as heat records continue to fall across the region.

Commentators are arguing that the growing public backlash against data centers, driven by concerns over energy use, water consumption and local impacts, has so far failed to become a broader reckoning about the climate cost of digital infrastructure. Writers on climate-focused online communities say the debate should connect data center expansion to emissions and grid strain, but that discussion remains largely framed around local nuisance rather than global warming.

Burlington County in New Jersey is part of a newly launched climate change resiliency study. Local outlets including the Courier-Post and Burlington County Times report the county's inclusion, which is expected to examine how the region can prepare for climate impacts such as flooding and extreme weather. Further details about the study's scope, funding and timeline have not been made clear in the initial coverage.

Warmer global temperatures are altering the timing of seasonal events, with spring arriving earlier in many regions and traditional calendar expectations no longer matching what people observe. Commentators note that earlier blooms, shifting migration patterns and milder winters are disrupting agriculture, gardening and cultural traditions tied to the seasons, prompting debate over whether the old sense of when spring begins still means anything.

Researchers are calling on organizers of the 2034 Winter Olympics in Salt Lake City, Utah, to use the Games as a catalyst for improving the region's air quality. Utah's valleys regularly suffer from pollution inversions, and scientists want the Olympic spotlight to drive lasting clean-air policy rather than temporary measures that fade once the event ends.

The MTA is repairing the Hudson Line as part of a wider strategy to protect New York's transit network from the impacts of climate change. An amNewYork op-ed argues the repairs are only one element of a broader plan needed to safeguard infrastructure against flooding and extreme weather that have repeatedly disrupted service along the corridor.

Scientists say autumn foliage across the United States is shifting, with peak colors arriving later or appearing less vivid in many regions. Experts attribute the changes to warming temperatures, altered rainfall patterns and longer growing seasons, which stress trees and disrupt the usual timing of leaf color change, raising concern among ecologists and leaf-peeping communities.
