A sobering new report predicts continued increases in Boston’s sea levels, extreme precipitation and higher temperatures. Climate Ready Boston is an initiative led by the City of Boston in partnership with the Green Ribbon Commission to develop resilient solutions to prepare our city for climate change. The group released worrying climate projections for what Boston is likely to experience over the coming years.
