extreme heat

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.

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.

The head of the UN Environment Programme says a lack of finance is the main obstacle to deploying solutions that help communities withstand extreme heat. The warning comes as heatwaves intensify worldwide, and it puts pressure on governments and lenders to fund adaptation measures such as cooling infrastructure and urban planning before the next severe heat season.

Thousands of people took to the streets in cities across France to demand stronger climate action. Organisers and participants expressed disappointment at the turnout, with one marcher saying: 'I wish there were more of us, after the summer we've just had' — a reference to the recent season of heatwaves and extreme weather. Demonstrators are calling on the French government to accelerate emissions reductions and strengthen environmental policy.

Demonstrators gathered in Paris to demand stronger climate action following a record-breaking summer heatwave in France. Protesters called on the government to accelerate emissions cuts and better prepare cities for extreme heat. The rally reflects growing public pressure in France for faster climate policy after a summer of unprecedented temperatures.

New reporting highlights that the global heatwave season has quietly expanded by 39 days, with high-temperature periods now starting earlier in the year and ending later than they once did. The finding is being shared as fresh evidence of shifting climate patterns, prompting discussion about longer exposure to dangerous heat and the growing strain on health systems, infrastructure and summer planning.

The head of the UN Environment Programme says financing is the main obstacle to rolling out solutions that help communities cope with extreme heat. The warning comes as heatwaves intensify worldwide, with measures such as cooling systems, urban shading and early-warning plans available but underfunded. The comments underline growing pressure on governments and donors to direct more money toward climate adaptation.

Climate rallies are being planned across France following a summer of record-breaking temperatures. Le Monde reports that demonstrations are being organised nationwide as campaigners seek to push the government for stronger climate action. The mobilisation follows months of extreme heat, with organisers and participants calling attention to the country's vulnerability to global warming.

Doctors are warning that people taking GLP-1 weight-loss and diabetes drugs such as Ozempic may face heightened health risks during the current heat wave. Concerns center on dehydration, as the medications can suppress thirst and appetite, potentially leaving users vulnerable to heat exhaustion and related complications. Patients are being advised to drink water regularly and take precautions in high temperatures as extreme heat persists across many regions.

Climate rallies are planned across France on Saturday following a record-breaking summer of heat and related weather extremes. Organisers and campaigners are expected to press the French government for stronger emissions cuts and climate adaptation measures. The demonstrations follow months in which the country experienced exceptional temperatures, adding pressure on officials as public attention returns to the pace of France's climate response.

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.

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.

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.

Swiss National Bank chairman Martin Schlegel said the central bank is monitoring how this summer's hot weather could push up food prices and feed into inflation. Extreme heat can damage harvests across Europe, lifting agricultural costs, and the bank is weighing whether such effects could influence its outlook for price stability in Switzerland.

Scientists report the discovery of a so-called 'fire amoeba', a single-celled organism said to survive temperatures far beyond what was thought possible for life. The finding challenges established assumptions about the upper heat limit for living cells. Details beyond the headline remain scarce, but the claim is drawing attention because it could reshape understanding of how and where life can exist, including in extreme environments.

Singapore recorded its joint-highest daily maximum temperature for September after the Woodlands Avenue 9 climate station reached 35.8°C at 3.27pm on Saturday, 26 September 2026. The reading ties the national September record and adds to ongoing concerns about rising heat in the city-state, with observers linking the milestone to broader climate change trends in Southeast Asia.

Forecasters and news outlets are warning that another round of hot weather is on the way, with rising temperatures expected in the coming days. Coverage is urging residents to prepare for heat conditions, reflecting ongoing concern about repeated heat events this season and their impact on health, infrastructure and daily life.

Austrian cooling specialist Noctua says it is working on bringing server-grade cooling capable of handling around 2000W of heat to desktop PCs. The technology, used in data centre environments to cool extremely power-hungry processors, would address the rising thermal demands of high-end desktop chips. The announcement has caught the attention of PC hardware enthusiasts watching power consumption climb.
