By mid‑July 2026 Europe and the United States were confronting record‑breaking heat waves that amplified urban heat‑island effects. Health agencies and municipal leaders warned the public and urged cities to adopt Arizona‑style adaptations – expanding green space, planting trees, applying reflective surfaces and creating cooled public areas.

The EU responded with the EUROASIS programme, a four‑year, €10 million Horizon Europe project coordinated by Wageningen University. A consortium of 29 organisations will trial 24 innovative solutions in pilot cities such as Amsterdam, Athens, Zaragoza and Reggio Emilia, with additional replication sites across Belgium, Portugal, Montenegro, Greece, France, Turkey and Ukraine. The effort targets vulnerable groups and aims to deliver practical tools for planners to safeguard public health.

As the heat persisted into August, European cities moved from planning to implementation. Researchers in Manchester showed that sprinkling captured rainwater on rooftops can cut air‑conditioning energy use and reduce extreme‑heat hours. Berlin established a climate‑adaptation steering committee and called for a binding heat‑protection plan, including cooled public buildings, extended pool hours and mobile “Cool Vans”. Bamberg proposed quick‑action measures such as mist showers and water refill stations, while Austria’s Styria launched a cross‑departmental heat‑impact assessment. German experts warned of rising forest‑fire risk, and Vienna’s Green Party pushed for wildlife heat‑protection rules.

- A University of Manchester study found that roof sprinklers using captured rainwater can reduce air‑conditioning energy consumption and lower extreme‑heat hours on rooftops. (single source)
- Berlin established a new climate‑adaptation steering committee that includes representatives from administration, science and civil society. (single source)
- The Bamberg city council faction proposed seven short‑term heat‑relief measures such as mist showers, refill stations, free drinking water and a map of cool locations. (single source)
- Styria’s state government will conduct a cross‑departmental assessment of heat impacts on water supply, health facilities, schools, agriculture and other sectors, and will draft a joint measures plan. (single source)
- Berlin Greens demanded a heat summit and a binding heat‑protection plan, proposing cooled public buildings, extended pool hours and mobile “Cool Vans” to distribute water and cooling towels. (single source)
- German experts warned that the 2026 heat wave increased forest‑fire risk, with about 2,600 ha of forest burned in the previous year, more than double the prior total. (single source)
- Vienna Greens called for a heat‑protection plan for wild and city animals, including “heat‑free” rules for carriage horses. (single source)
- A dozen deer died in Austria while trying to drink from a canal during the heat wave. (single source)
