8 charts that show the toll climate change will take on Boston

City officials this week released a report that included updated projections of how climate change is expected to impact Boston and outlined ways the city can prevent and brace for the potentially devastating effects.

“Boston residents are already impacted by extreme heat, rain, snow and flooding,” Austin Blackmon, the city’s chief of environment, energy and open space said in a statement. The report “shows that these trends are expected to continue, and now we have a better understanding of what we need to do to prepare.”
