The city has turned the data from its massive Climate Ready Boston report into an interactive map that allows you to explore many of the report's findings and projections.
The tool allows you to layer various data sets onto the map, including sea level rise and flood risk, as well as vulnerable populations and areas of high temperatures. You can zoom in to or search specific places within city limits to see effects there.
