The development is expected to influence temperatures, rainfall and storm activity across many regions, and is drawing widespread attention as scientists and the public assess the implications for extreme weather worldwide.

Scientists and commentators say the current El Niño is unlike any previously observed, with ocean temperatures in the Pacific reaching record highs. The event is being linked to extreme weather worldwide, including heatwaves, flooding and droughts, and is fuelling debate about how climate change may be intensifying the natural cycle.

Scientists are developing new approaches to control mosquitoes, the animal responsible for more human deaths than any other, as climate change lengthens mosquito seasons and expands the areas where the insects can spread diseases such as malaria and dengue. Reporting highlights that longer warm periods give mosquitoes more time to breed and transmit dangerous illnesses, prompting research into novel targeting methods.

A new report says global temperatures have reached record highs as the El Niño climate pattern strengthens in the Pacific. El Niño, which warms ocean surface waters and alters weather worldwide, is adding to the underlying warming trend driven by greenhouse gas emissions. Scientists warn the combination could push average temperatures to new extremes in the coming months, with implications for heatwaves, droughts and storms across many regions.

Scientists and news outlets are raising alarms about a slow-moving, planetary-scale Kelvin wave in the Pacific Ocean that is heading toward the California coast. These massive underwater waves along the equator can redistribute warm water and influence weather patterns, and observers are watching closely for potential effects on coastal conditions and climate.

A Brazilian climate scientist has launched a bid for political office, saying the country's politicians have failed to listen to scientific warnings about climate change and environmental policy. The move reflects growing frustration among researchers who argue that science is being ignored in Brazilian decision-making, and it adds a scientific voice to the country's political contest.

Peter Barrett, a leading figure in Antarctic science in New Zealand and internationally, has died. Colleagues describe him as a legend in the field, noting that even in death he left behind a list of tasks and challenges, reflecting his lifelong commitment to Antarctic research and climate issues. Tributes have come from across Aotearoa and the wider scientific community.

Scientists in Germany are preparing to copy and store vast troves of American climate data, fearing the Trump administration could alter, restrict, or remove federal climate records. The effort has been likened to building an ark, preserving scientific information outside the United States in case it becomes unavailable at home, and has drawn attention as researchers weigh risks to publicly funded datasets.

New coverage warns that Earth's magnetic poles could be heading toward another reversal, an event where the planet's north and south magnetic poles swap places. Reports focus on what such a flip could mean for climate, navigation systems, satellite operations and the shielding that protects Earth from solar radiation, though scientists note reversals happen gradually over thousands of years.

NASA scientists are mapping vast valleys buried beneath the Greenland ice sheet, revealing dramatic hidden landscapes that were shaped before ice covered the island. The research helps scientists understand how the bedrock terrain influences ice flow and could improve predictions of how the ice sheet will respond to climate change and contribute to global sea-level rise.

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.

A massive Kelvin wave is reported to be moving toward California, raising questions about what it could mean for the state's coastline and weather patterns. Kelvin waves are large movements of warm water across the Pacific that can influence ocean temperatures and climate conditions along the West Coast. Coverage is focusing on the potential impacts for California as the wave approaches.

Germany is reportedly creating an archive to preserve United States climate data, described as a digital Noah's Ark. The project is understood as a safeguard against the potential loss or removal of federal climate datasets, allowing scientists to keep access to long-term environmental records regardless of what happens to US government databases.

Scientists have observed that the amount of dust in Earth's atmosphere has declined, reversing a previous trend. NBC News reports the shift is described as mysterious, with the cause of the reversal not yet explained. Dust in the atmosphere affects climate, air quality and weather patterns, so researchers are paying close attention to what is driving the change.

A new study questions the widely held idea that climate change is driving a boom in global squid populations. Researchers challenge assumptions that warming oceans have benefited squid, suggesting earlier conclusions may need revision. The findings matter for fisheries and marine ecosystems, where squid play a key role and where management decisions have partly relied on expectations of continued growth.

New research suggests that rising temperatures and shifting rainfall patterns could significantly alter where Chinese milk vetch, a legume long grown as green manure in southern China's rice paddies, can thrive. The plant plays an important role in sustaining soil fertility and reducing fertilizer use, so scientists warn that changing climate conditions may force farmers to adjust how and where they cultivate it.

Scientists are urging that funding for the USDA Climate Hubs be extended. The regional hubs help farmers, ranchers and land managers adapt to climate change by translating research into practical guidance. Supporters argue the network delivers value on the ground and should not lapse, though details of the funding request and the response from policymakers remain unclear.

An article examining the environmental impact and greenwashing of artificial intelligence includes a fact check of Donald Trump's climate remarks. It explains that his references to people warning "we'll all be dead in twelve years" stem from media coverage of a 2018 United Nations Intergovernmental Panel on Climate Change report, rather than scientists' actual statements. Readers are sharing it as a useful example of climate misinformation being corrected within broader tech-environment reporting.

Scientists at a Colorado cold laboratory are working to better understand hail as the damage it causes continues to grow. Hail already causes billions of dollars in losses each year in the United States, and researchers warn that a warming climate could make severe hailstorms more frequent or more destructive. The reporting by Hannah Covington in High Country News highlights how little is still known about how hailstones form and grow inside storms, and why improved forecasting matters for insurers, farmers and homeowners across hail-prone regions.

A weather explainer is looking at the satellites used to study the world's oceans and monitor El Niño. Coverage focuses on how these spacecraft measure sea surface temperatures and other ocean conditions, which scientists use to track the climate pattern and improve forecasts of its effects on weather around the globe.

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.

Billionaire investor Mark Cuban asked Elon Musk's chatbot Grok which risks are most likely to cause human extinction within 25 years. According to reports, the AI responded that artificial intelligence is roughly 3,000 times more likely than climate change to be the cause. The claim has drawn attention because both figures are speculative model outputs rather than established scientific estimates, and climate scientists generally rank climate change among the most serious long-term global threats.

A new interactive map charting glacier extinction has been launched, tracking which of the world's glaciers are projected to disappear and when. The tool comes as scientists warn that glacier loss is accelerating worldwide, threatening water supplies for millions and raising concern among skiers, mountain communities and climate researchers.

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.
