Subway Heat Soars: New Study Confirms Rider Complaints

A recent study published in Nature Cities analyzed over 85,000 social media posts and reviews from the New York, Boston, and London subway systems. Researchers found a direct correlation between rising outdoor temperatures and an increase in rider complaints about heat underground.

Analysis of posts from 2008 to 2024 revealed that for every 1-degree Fahrenheit rise in outdoor temperature, subway complaints increased by 10% in Boston, 12% in New York, and 27% in London. This highlights the growing impact of climate change on urban transit infrastructure.
