LTE: We need to build green roofs in Cambridge, joining other cities in climate change fight

Mother Out Front Florrie Wescoat asks an excellent question in her recently published Letter to the Editor at Cambridgeday.com and announces a new campaign from Mothers Out Front in Cambridge, MA:

Let’s take a bird’s eye view of Cambridge. We see mostly empty rooftops, and some with mechanical systems on top to protect them from flood damage. Many of the flat roofs are heat-absorbing black, which can reach upwards of 140 degrees Fahrenheit in the summer, increasing the city’s heat island effects. These aren’t the rooftops that a city such as Cambridge, which is committed to fighting climate change, ought to have, and we know it. Why aren’t we acting on what we know? Why don’t we have more white roofs that can reduce surface temperatures by an average of 43 degrees in the summertime? More solar collectors? Where are roofs with growing plants?
