Fall 2007 Update: Range of Potential SST Change on the Northeast Shelf

Maps of SST

The maps show the range of potential SST change by the end of the 21st century under the four scenarios used to drive the climate model. The committed scenario suggests SST will change on the order of 0.5-1.0°C without an increase in anthropogenic forcing. Scenarios B1 and A1B suggest that shelf subregions like the Gulf of Maine and Southern New England will likely see increases of SST on the order of 2-4°C. The most dramatic changes are suggested by the model output for scenario A2, which suggests that the Northeast Shelf in general will increase on the order of 4°C, and that the Gulf of Maine could see increases in SST as high as 7°C.
