Subway Heat: Cities Struggle With Underground Swelter
11 Mar
Summary
- Subway stations exceed 100 degrees Fahrenheit in summer.
- Social media data reveals thermal discomfort in major cities.
- Researchers urge more public data on underground environmental conditions.
Extreme heat is not just an above-ground issue, as subway systems worldwide grapple with sweltering underground temperatures. New York City commuters have long endured stations exceeding 100 degrees Fahrenheit during summer months, creating an unpleasant and potentially unhealthy environment. The pervasive stench accompanying this heat prompts serious consideration of relocation by many residents.
To address this growing concern, researchers from Northwestern University, Giorgia Chinazzo and Alessandro Rotta Loria, leveraged social media data. They analyzed passenger complaints from New York City, Boston, and London to quantify thermal discomfort across these major metropolitan transit networks. Their study, published in Nature Cities, underscores a significant lack of readily available, quantitative data on underground environmental conditions. This deficiency is particularly alarming given the escalating risks associated with climate change and more frequent extreme heat events.
