- Across Europe, heat adaptation plans are being put to a brutal test
France's heat-resilience programs, developed after a deadly 2003 heat wave, are being tested by record-breaking European temperatures. Cities have implemented measures like cooling centers and tree planting, but recent heat waves have caused over 240 heat-related deaths across France and Spain, with vulnerable populations most at risk.
- Desperate for shade on your walk? There’s (almost) an app for that.
A new tool called Cool Routes, developed by Arizona State University, helps pedestrians find cooler, shadier walking paths in cities by calculating heat exposure using factors like shade and weather data. The tool aims to address the urban heat island effect, which makes walking in cities dangerously hot, and is open-sourced for broader use.
- Oppressive heat and humidity drain Karachi’s life and energy
Karachi residents, particularly underprivileged groups like bike riders, laborers, and street vendors, face severe challenges due to extreme heat and humidity exceeding 45°C, linked to climate change. The lack of shade and infrastructure exacerbates the urban heat island effect, while workers report exhaustion and vehicle overheating.
