Interview on Radio Ecoshock about cooling cities

Daily hours of strong heat stress (‘felt’ temperature exceeding 38 ºC) during a week-long heatwave during the start of the 21st century (SoC), and end of century (EoC) under moderate (RCP 4.5) and high (RCP 8.5) emissions scenarios, with and without implementation of several heat adaptation strategies (Jiang et al. 2025).

In the wake of the publication of a major new study on urban heat adaptation from the Urban Climate Adaptation Lab and published in the Proceedings of the National Academy of Sciences of the USA, Prof. Krayenhoff speaks with Alex Smith, host of Radio Ecoshock.

“We know cities will get even hotter. How can we stay comfortable, without burning more fossil fuels? A team of experts led by Dr. Timothy Jiang of Pacific Northwest National Lab [and former PhD student at University of Guelph] investigated common cooling ideas, from making roads white to living green roofs. What works best in most climates? We get answers – and a new mantra for urban development – with co-author Scott Krayenhoff.”
