A vast heat crisis is unfolding across Europe, with about 45% of 854 cities in 30 countries breaking or nearing wet-bulb globe temperature records, signaling extreme heat stress and limited cooling for populations.

The heatwave is driven by a persistent high-pressure heat dome that traps heat, drawing warmth from North Africa and amplifying it with humidity.

The event began around mid-June, with daytime temperatures often above 40°C and dangerously humid nights, increasing heat stress on people.

Authorities emphasize preserving emergency and healthcare services and instruct state events to avoid serving alcohol to help medical staff protect vulnerable populations.

Experts note that cooling options are not accessible to everyone, underscoring unequal vulnerability and the need to target protection for the most at-risk individuals.

France’s prime minister convened a heat crisis meeting and ordered planning for better adaptation, including potential use of air conditioning to shield vulnerable groups.

Leading voices caution that attribution of the heat to climate change may be understated, while stressing that infrastructure and behavior must adapt as heat becomes more frequent and intense.

Media coverage varies, with some outlets linking health risks to climate change and urgency for adaptation, while others critique official adaptation efforts and debate school closures and public messaging.

Prominent scientists argue fossil fuel emissions are driving disruption in homes and daily life and call for faster climate action and recognition of repeated warnings about escalating heat.

Officials urge hydration, reduced outdoor activity during peak heat, and keeping parks open, supported by a hot-weather helpline for guidance.

Paris authorities enacted an alcohol ban across several districts starting mid-June to reduce heat-related risks.

WWA findings link human actions to the severity of the heatwave, highlighting mitigation potential through emissions reductions, though concrete actions remain uncertain.
