Could Caves Be the Answer to Europe's Sweltering Heatwaves?

As Europe grapples with intensifying heatwaves, a seemingly simple social media post has ignited a conversation about an unconventional solution: living underground.

Emilie Gasc, an announcer for Ligne de cœur on RTS, shared on Facebook in late June that she had set up a camp bed in her building's basement to escape the stifling 30°C heat in her south-facing apartment in Lausanne. Her post, shared during a severe heatwave, resonated with many and prompted a broader question: Could caves and underground spaces be the answer to our increasingly sweltering summers?

With projections suggesting Central Europe could experience temperatures as high as 50°C within two decades, the idea of seeking refuge below ground is gaining traction. The article posits that transforming existing caves or constructing new subterranean homes could offer a viable strategy for maintaining acceptable indoor temperatures, providing a stark contrast to the unbearable heat experienced in conventional above-ground structures.

This exploration into troglodyte living, or dwelling in caves, comes as a direct response to the escalating climate crisis and its impact on daily life. While the concept might seem radical, the article suggests it warrants serious consideration as a potential adaptation strategy for future living conditions.
