What it is
Using social media and meteorological data from 2010 to 2024 in China, the authors quantified the mismatch between physical heat exposure and public emotional responses, identified its drivers, and projected it under different shared socioeconomic pathways. They found that 84.9% of cities suffered high-intensity emotional shocks, substantially exceeding the 52.1% facing severe physical exposure, with underdeveloped regions showing especially prolonged emotional recovery. Physical resilience was driven mainly by socioeconomic and land-cover factors, while emotional resilience was more sensitive to the intensity and characteristics of heat events.
Why it matters
Heatwave research has focused on physical exposure, but this shows public emotional impact is both more widespread than physical exposure and unevenly distributed, hitting underdeveloped regions with especially prolonged recovery. Projections that emotional responses declined about 26% faster than physical heat exposure over 2025 to 2050 imply the two vulnerabilities need to be planned for separately.
