The Massachusetts Executive Office of Energy and Environmental Affairs released a blueprint September 27 for addressing the impacts of climate change on the state. The Massachusetts Climate Change Adaptation Report includes a sector-by-sector look at how climate change could impact natural resources and habitat, infrastructure, human health and welfare, local economies and governments, and coastal zones and oceans. The report includes an overview of observed and anticipated changes and impacts and a set of guiding principles to follow in addressing those changes. Twelve other states have completed similar adaptation plans.
