- London bus drivers plan to strike later this month over cab temperatures reaching close to 40°C, prompting Mayor Sadiq Khan to declare the conditions unsafe and Arriva to warn that fleet upgrades will take time.
- Rail services in southern England have been disrupted as drought shrank the soil beneath the tracks, destabilizing embankments, while heat-warped rails have forced operators to impose lower speed limits.
- England's harvest could be the worst on record, with the Energy and Climate Intelligence Unit projecting cereal and oilseed yields down as much as 2.5 million tonnes — a £390 million revenue hit for arable farmers — after grass growth halved.
- Wholesale fresh-produce prices have climbed sharply: tomatoes up more than 60%, iceberg lettuce 90%+, and potatoes 40%+, with a possible super El Niño threatening the import backup option.
- A Bristol judge in July told jurors to follow proceedings via a virtual link because the dock was unusable in the heat, crystallizing the absence of any UK legal maximum working temperature.
- The Climate Change Committee has called for every UK school to have air conditioning by 2050 and suggested shifting exams away from June after evidence that heat degrades pupils' test performance.
Why it matters: With a third bad harvest in a row costing arable farmers £390m and no legal cap on workplace temperatures, the UK is absorbing simultaneous shocks to its food supply, transport reliability and worker safety that fall hardest on frontline staff and shoppers now paying 60-90% more for fresh produce.
