Keeping Metro Boston Cool: Building a Heat Resilient Region

Take the Survey!

How do you experience heat? How do you cool down? We're working with the Metro Mayors Coalition to create a plan to address heat-related health concerns and reduce heat islands in Metro Boston. We need to hear from you!


Extreme heat days, days over 90 degrees, are projected to increase from 11 up to 40 days annually by 2030. In the summer of 2021, the Metro Boston region saw 24 days with temperatures 90 degrees or above. As we enter yet another summer season, MAPC hosted Keeping Metro Boston Cool: A Public Forum on Building a Heat-Resilient Region, to help prepare individuals and municipalities alike for rising temperatures.  

Keeping Metro Boston Cool brought together speakers from the public and private sector to discuss how to make the Metro Boston region resilient to extreme heat. MAPC’s Sasha Shyduroff discussed the impacts extreme heat has on our health, safety, and infrastructure and how the Metro Mayors Heat Preparedness and Adaptation Plan hopes to address these issues.  

Chelsea City Manager, Tom Ambrosino kicked us off with discussion of Chelsea’s work on heat resilience and Darya Mattes explained how the newly formed North Suffolk Office of Resilience and Sustainability is bringing together Chelsea, Winthrop, and Revere to work together on issues of heat.  

The presentation included topics ranging from how communities combat heat to cooling the built environment. We heard from Aaron Greiner, founder of CultureHouse on how transforming unused spaces not only acts as a place to keep cool but also forms community. Erin Noël from the City of Somerville talked about how Keep Cool Somerville collected resident’s experiences during high heat days to inform the city of Somerville’s strategy for extreme heat. Dira Johanif of the Charles River Watershed Association shared how extreme heat impacts the Charles River and how green infrastructure can help cool our shared spaces and protect the river. Lastly, John Bolduc from the City of Cambridge discussed how the urban heat island effect is warming urban areas and the solutions Cambridge is employing to reduce it.
