The climate will continue to change even as greenhouse gas emissions come down. Some changes, such as sea-level rise, heat waves, and increases in storm intensity or frequency, pose major risks to Boston, its infrastructure, its tax base, and its residents. For these reasons, Boston has a responsibility to prepare for climate change, even as we work to lessen its impacts. Climate adaptation-preparing for the different local environmental conditions that result from climate change-is an essential part of climate action.

Projected Climate Impacts
If current climate trends continue, heat waves and smog alerts are projected to become more frequent in Boston. Flooding from coastal storms will become more common and more extensive. These, in turn, will affect the health of residents and visitors, the safety of neighborhoods, the success of business and institutions, the viability of plants and animals in local parks, and the ability of the government to cope with short-term emergencies and longer-term stresses. Potential costs for medical care, property and infrastructure repair, and lost opportunity figure in the billions of dollars. There is uncertainty about the speed at which these things occur, but they have started.
