HeatWave

South Korea is seeing dramatic weather swings: Daejeon hit 31.5 degrees and Seoul 29.6 degrees, the hottest mid-October in 119 years, before temperatures drop sharply nationwide as rain moves in from Sunday night. Morning temperatures in northern Gyeonggi fell to around 5 degrees with 15-degree daily swings. Forecasters are also warning of a possible unusually warm winter with heavy snow, prompting heavy public interest in the forecast.

A new piece argues that the word 'heatwave' no longer captures the severity of today's extreme heat events, prompting debate among journalists and climate communicators about how to describe them. Critics say the term sounds routine and fails to convey the deadly, unprecedented nature of modern heat, as record temperatures increasingly hit regions unprepared for them.

Deutsche Welle examines whether the extreme heat of the summer can be described as normal. The report looks at record-breaking temperatures and questions whether such heatwaves should now be considered typical in a warming climate. It reflects a broader debate among scientists and the public about how climate change is reshaping what counts as ordinary weather.

Australia's ABC News is examining warnings that the developing El Niño could become the largest ever recorded. The climate pattern, which warms the Pacific Ocean and alters weather worldwide, threatens more intense heatwaves, droughts and bushfires in Australia while bringing storms and flooding to other regions. Coverage is focusing on how a record-strength event would test communities, agriculture and emergency systems already strained by recent extreme weather.

Researchers have published a new study setting out how whole cities can be prepared for extreme heat events. The work, covered by Phys.org, argues that heat planning must move beyond individual buildings to entire urban areas as heatwaves grow more frequent and severe. The findings are being shared among readers following environment and weather topics, with discussion of rising temperatures and urban adaptation.

A new analysis attributes around 710,000 deaths in a single year to extreme heat, a toll exceeding deaths from malaria and HIV. Alongside the findings, 146 experts are calling on health authorities to formally declare climate change a global health emergency. The figures are prompting debate over whether health systems and governments are adequately prepared for intensifying heatwaves.

Arunabha Ghosh, climate policy expert and CEO of the Council on Energy, Environment and Water, appeared on Raj Shamani's podcast to discuss how extreme heat is becoming a $180 billion problem for India. The conversation covers heat's impact on productivity, agriculture, health and the economy, and what India can do to adapt. The episode is drawing large audiences as India faces increasingly severe heatwaves.

Syngenta Group reported lower revenue, saying a heatwave hurt sales. The agribusiness giant attributed the decline to weather conditions that affected demand for its agricultural products, making climate impacts on farm supply businesses the focus of coverage.

Scientists and news outlets are explaining how the current El Niño differs from previous events, pointing to its behaviour against a backdrop of record global ocean and air temperatures. Experts say climate change is altering how the climate pattern unfolds and intensifies, with implications for heatwaves, droughts and extreme weather across the Americas, Australia and Southeast Asia. Coverage is urging readers to understand the shift as the pattern strengthens.

The Alaska Fisheries Science Center says a surge in hybrid snow-Tanner crab populations stems from marine heatwave conditions combined with decreased competition and predation in the region's waters. The findings shed light on how warming ocean temperatures are reshaping crab species dynamics, a matter of keen interest to Alaska's commercially vital crab fisheries.

Many people in Bulgaria are searching for 'времето' — the weather — with search interest rising sharply. No specific event is attached to the term, suggesting general concern about current or upcoming conditions. Weather searches typically climb during storms, heatwaves or sudden temperature shifts when people plan travel and daily activities.

Oracle has introduced HeatWave ML, a capability that embeds machine learning directly into its HeatWave database, allowing users to train and run models without moving data to separate analytics platforms. The move aims to simplify AI workflows for enterprise customers and reduce the cost and complexity of managing standalone machine learning tools.

Health and climate experts are calling on the United Nations to formally declare climate change a global health emergency. The appeal argues that rising temperatures, extreme weather and air pollution are already causing deaths and disease worldwide, and that treating the crisis as a health emergency would push governments to act faster on emissions and protect vulnerable populations.

Persistent extreme heat across Europe is changing how citizens think about climate change and how they vote, with climate policy increasingly shaping political choices. Commentators say repeated heatwaves are turning an abstract issue into a lived experience, putting pressure on parties and governments across the continent to respond with stronger climate action.

A global map of temperature anomalies highlights widespread above-average conditions across the world's oceans, with several regions experiencing significant marine heatwaves. The visual underlines how ocean temperatures remain far above historical norms, a trend scientists link to ecosystem stress, coral bleaching and broader climate change impacts.

A debate is underway over whether AI should be used to write emergency alerts, particularly for climate-related disasters such as floods, heatwaves and storms. Critics question whether automated systems can convey urgency accurately, while supporters point to faster drafting and wider dissemination of life-saving warnings as AI adoption in public alerting grows.

A photograph taken in Tokyo in July 2025 shows people using a backstreet bridge as shelter from extreme summer heat, framed as 'a haven from the heat'. The black-and-white film image has drawn attention for capturing how residents adapt to dangerous temperatures, a recurring concern during Japan's increasingly severe summer heatwaves.

Climate scientist Paul Beckwith has released a video lecture and literature review examining the science behind the 2026 European heatwaves, covering extreme heat, weather patterns and their links to climate change. The material is being shared among climate-focused audiences discussing the heatwaves affecting Europe and the wider climate emergency.

The European Union has introduced a new climate resilience framework, following a summer of extreme heat across the continent. The plan is intended to better prepare member states for heatwaves, droughts and other climate impacts. Details of funding and implementation remain limited, and reactions from member governments and climate groups are still emerging.

Rising ocean temperatures along the Pacific are drawing mobulid rays, close relatives of manta rays, into waters off California, a region traditionally too cold for them. Sightings and strandings of the warm-water species have increased as marine heatwaves push wildlife northward, adding to concern about how climate change is reshaping ocean ecosystems along the US West Coast.

DeSmog reports on how far-right political movements exploit climate disasters to advance their agendas, converting crises such as floods, wildfires and heatwaves into opportunities to gain votes and consolidate power. The investigation examines the strategies and rhetoric used to turn extreme weather events into political capital, a pattern analysts say is becoming more common as disasters intensify worldwide.

Reports warn that modern building design is still based on historical climate data, meaning structures are being built for weather conditions that no longer exist. As heatwaves, storms and rainfall patterns intensify faster than building codes and standards are updated, architects and engineers argue that current practices leave new buildings ill-prepared for the realities of a warming world, prompting calls to redesign standards around future climate projections.
