Ambulance services have reported record call volumes, amber heat-health alerts have been issued, thunderstorms and fires have followed the heat, and officials are urging caution around open water.
A pan-European heatwave has shattered May temperature records in the UK and France, with London and Kew Gardens reaching 35C while minimum temperatures stay above 20C for consecutive nights. Met Office warnings are in place as authorities warn of heat-related health impacts and potential storms across parts of England.
A series of policy changes and local actions across the US and Hawaii are threatening tax credits, farm and rooftop solar projects, and small-business solar adoption. While some communities push for faster rooftop and street-level solar deployments, lawmakers are revisiting credits and funding rules, risking delays for ongoing installations and new deployments.
A cross‑country study using mobile phone data finds people retreat indoors during extreme heat, while malls and parks offer refuge. The UK and Europe face rising temperatures and pressure to adapt school and city infrastructure for resilience. Governments are rolling out heat action plans amid social inequalities in vulnerability.
NHS England has published data showing an average of 2,241 patients daily experienced corridor care in emergency departments in May, with 669 more treated in wards. The figures highlight a national crisis, concentrated in a few trusts, as ministers pledge to eradicate the practice.
A sweeping heatwave has driven temperatures above historical highs across France and neighboring countries. Officials have issued red and orange alerts, with tens of millions affected as authorities warn of health risks, power disruptions, and travel delays. Several cities have seen record temperatures, while hospitals and schools adjust operating hours to cope with the extreme heat.
A persistent high-pressure heat dome is trapping heat and humidity over continental Europe, driving record temperatures from France to the UK. The phenomenon is linked to escalating temperatures due to fossil-fuel emissions, with authorities warning of health risks, wildfires, and rising energy demand.
As temperatures surge across the UK and Europe, schools face red heat warnings. Authorities urge adaptive measures from headteachers, including flexible timings, ventilation, hydration, and possible early closures. The debate over whether to close schools or keep them open intensifies as unions demand better climate-ready infrastructure.
Heat waves have intensified health risks, worsening heart and kidney conditions, triggering heat exhaustion, and contributing to inflammatory issues. Experts urge hydration, shade, and cooling measures as high temperatures persist and climate change drives higher heat.
Provisional temperatures have surpassed long-standing June records across England, with 35.8C in Wigonholt and 35.7C in Charlwood, amid a Met Office red heat warning. Forecasters say figures could climb further as a heat-dome over western Europe drives extreme heat, health warnings are in place, and schools and transport are disrupted.
European heat waves persist with record-setting temperatures across multiple countries. Authorities warn of health risks, power strains, and disruptions to travel and schooling. Forecasters expect a gradual cooldown starting Friday, as the continent faces a second consecutive heat dome driven by high pressure.
A new Nature Climate Change study shows heat stress is expanding globally, with hotter nights intensifying risks. Europe faces record heat, sleep deprivation, and mounting health and infrastructure impacts as nights fail to cool. Authorities warn this will demand adaptation and resilience measures in coming years.
Public Health France has recorded 5,764 excess deaths between 17 June and 2 July during an exceptional June heatwave, the highest heat-related excess mortality since 2003. France recorded 21,674 deaths against 15,910 expected; two-thirds of the excess were people aged 75 and older and more than half occurred between 25–27 June.
Europe endures a record heat wave tied to climate change as France faces rising deaths. Only ~20% of European homes have air conditioning, compared with ~90% in the U.S., highlighting a widening cooling gap and policy tensions across the continent.
UK households face water-use restrictions as heatwaves push demand. South East Water and Southern Water have introduced temporary hosepipe bans in Kent, Hampshire and the Isle of Wight, with further restrictions possible as a third heatwave of the year looms. The Met Office warns continued extreme temperatures, while water firms stress reduced outdoor use to protect supplies.
Public Health France has counted 8,973 deaths in the week of June 22–28, a 29% rise from the prior week, with 2,025 additional deaths recorded overall. Paris remains hardest hit as heat records are broken across Europe amid a heatwave linked to climate change.
The National Energy System Operator has issued a margin notice for Thursday evening due to extreme European temperatures, marking the third such notice this year. The move signals a higher cushion between demand and supply, as heat drives up electricity use and strains generation.
A wave of hot weather has triggered new warnings about how heat changes physiology and mood. Experts say heat triggers vascular changes, dehydration risk, and cognitive and mood shifts, with women facing particular risks. Readers are advised to stay hydrated, avoid peak heat, and monitor vulnerable groups.
A sweeping heat dome has kept tens of millions under heat alerts from the Midwest to the East Coast. Overnight temperatures are failing to cool, heightening health risks and straining power grids. El Niño is intensifying the heat, and cooling centers, water, and hydration remain critical.
A series of articles shows the impact of unusual heat in July 2026: posties, carers, shop staff and farmers face longer hours, dehydration risks, and cooling challenges. Debates grow over maximum workplace temperatures as policymakers and unions push for safeguards amid a changing climate.
A study from the Bumblebee Conservation Trust shows UK bumblebees struggle to fly and forage as heatwaves push body temperatures toward lethal levels. Data from 2022 reveals declines in red-tailed, buff-tailed and common carder bumblebees, with concerns about ongoing drought and climate trends. Some species are faring better this spring, but the year remains uncertain.
