Socializing with ScientistsSocializing with ScientistsScott MacIvor wants people to enjoy green spaces in cities (he's an urban ecologist)When he was a child in Kitchener, Ontario, Scott MacIvor would go on urban walks with his mom. He had a bucket, and was allowed to bring home one piece of nature each day: a snake, or a bumblebee, a caterpillar. He loved examining them all.Now Scott is an urban ecologist at the University of Toronto, working to connect people with the nature that's hidden all over the places where humans live, especially cities. He uses drones, thermal imaging, and other cutting edge technologies to study urban ecosystems to see how they’re doing and how th...2025-06-181h 05Socializing with ScientistsSocializing with ScientistsScott Krayenhoff helps hot cities cool off (he's an urban climatologist)Scott has always been a deep thinker. Dinner table conversations on his family's homestead on Vancouver Island instilled in him a strong environmental ethic, and a love for math and science pushed him to excel in college.But when a professor posed the question, how much cooler would Toronto's summer climate be if half the rooftops were green and plant-based? his imagination took off, and he dove into the field of atmospheric science.Scott Krayenhoff is now an associate professor at the University of Guelph's School of Environmental Sciences and recently published a research paper...2025-05-281h 01The RADIO ECOSHOCK ShowThe RADIO ECOSHOCK ShowRadio Ecoshock: Cope and Cool DownWe have to cope.

He is also an ORISE Fellow in the US Centers for Disease Control and Prevention Climate and Health Program. We’re talking about his paper “Climate change and infrastructure risk: Indoor heat exposure during a concurrent heatwave and blackout event in Phoenix, Arizona” recently published in the journal “Urban Climate” with co-authors Brian Stone, Mayuri Rajput, Ashley Broadbent, Scott Krayenhoff, Godfried Augenbroe, Matei GeorgescuPaper: http...2021-11-1450 minThe Why & How PodcastThe Why & How PodcastWhy is it so hot in the city?You've felt it. It’s hotter in the city. But why? Prof. Scott Krayenhoff of the School of Environmental Sciences explains why our cities are hotter than they should be, and what can be done to cool them down. Unfortunately, the solution is complicated by climate change. And keeping colder cities warm in the winter actually makes them more liveable. Thankfully Scott’s got some advanced computer models and equipment to try to figure out a solution.   Descriptive transcript available here: https://www.uoguelph.ca/oac/system/files/Podcast%20%2310%20-%20Why%20is%20it%20so%20hot%20in%20the%20city.tx...2019-11-2740 min
