In cities, we can reverse climate change trends if we renature urban areas. By interweaving green infrastructure within the built environment, we can tackle some of the effects of human-induced warming locally. At the same time, we can limit further urbanization, which will increase the severity of heatwaves as well as precipitation and resulting runoff intensity.

A grass-roots climate action group powered by the volunteer efforts of moms dared to imagine what Cambridge, MA could become if its rooftops were transformed by pollinator-friendly gardens, meadows, and a farm or two.
