# Heatwave in London: Climate conference cancelled due to 37-degree temperatures

### Irony of fate: climate conference derailed by climate realities

A curious but telling incident occurred in London: an international conference dedicated to adapting cities to global warming was officially cancelled. The paradox of the situation is that the very issue intended for discussion—extreme heat—caused the event to be called off. Air temperatures in the British capital reached anomalous levels of +37 °C, making the forum impossible to hold.

### Infrastructure crisis in historic buildings

Organizers were forced to admit that the chosen venue was technically unprepared to host guests under such conditions. The building intended for expert sessions lacks central air conditioning systems. This is a classic problem for London's historic architecture and many other European capitals: buildings were designed to retain heat during harsh winters, which leads to the opposite effect in the face of modern anomalous heatwaves.

### Systemic risks for megacities

The situation in London illustrates deeper challenges faced by northern cities. Meteorological data from the UK Met Office confirms that heatwaves in Western Europe are becoming increasingly intense and prolonged. Experts highlight key factors making urban agglomerations vulnerable:

- **Deficit of climate control equipment:** The proportion of residential and commercial property in the UK equipped with stationary air conditioners remains minimal compared to countries in Southern Europe and North America.

- **"Urban heat island" effect:** Dense construction, abundant concrete, and asphalt accumulate solar radiation. As a result, temperatures within the city limits can remain 3–5 °C higher than in suburban areas.

### Safety and economic consequences

The decision to cancel was dictated not only by comfort but also by labor safety regulations. Holding multi-hour discussions in an enclosed room at temperatures around +37 °C creates direct health risks for participants. Analysts of climate programs note that this incident demonstrates the systemic unpreparedness of municipal infrastructure for rapid adaptation.

Modernizing engineering networks and changing building standards require colossal long-term investments. According to expert estimates, bringing London's existing administrative buildings into compliance with new temperature regimes will require not only targeted funding for the utilities sector but also changes to urban planning legislation. While climate change is occurring at an accelerated pace, cities are forced to find solutions amidst an already unfolding crisis.
