Climate Change in the Gulf of Maine

The disruption of climate change in Maine is already evident, affecting fisheries, agriculture, waterfront development, and both winter and summer tourism. This is due in part to the fact that the Gulf of Maine, the 36,000 square miles of relatively enclosed ocean stretching from Cape Cod to Nova Scotia, is warming faster than 99% of the world’s oceans.
