extreme heat

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.

New reporting indicates the global heatwave season has grown by roughly 39 days, with extreme heat now arriving earlier in the year and lingering longer before it ends. The finding adds to growing evidence that warming temperatures are extending dangerous heat periods worldwide, raising concerns about health risks, strain on power grids, and impacts on agriculture as communities face prolonged exposure to high temperatures.

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.

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.

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.

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", an organism said to survive at temperatures beyond what was thought to be life's upper limit. If confirmed, the find would force a rethink of the thermal boundaries of life on Earth, with implications for the search for life in extreme environments such as deep-sea vents and possibly other planets.

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.
