extreme heat

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.

As a heat wave grips much of the United States, doctors are warning that people taking GLP-1 medications, such as Ozempic and Wegovy, may face heightened health risks. These drugs can contribute to dehydration, which raises the danger of heat exhaustion and other heat-related illness. Health professionals are advising patients on GLP-1 therapies to drink plenty of fluids, limit strenuous outdoor activity, and watch for warning signs like dizziness and nausea during extreme 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.

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.

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.

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.

An editorial in Texas argues the state cannot shield itself from climate change by preventing students from learning about it. The piece, published by the San Antonio Express-News, presses back against efforts to limit or soften climate science in Texas schools, warning that ignorance will not protect the state from rising heat, drought and extreme weather already affecting the region.

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.

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.

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.
