The waters off of New England are already warming faster than most of the world's oceans, and they're nearing the end of one of the hottest summers in their history.
A scientist with the Gulf of Maine Research Institute in Portland says the average sea surface temperature in the Gulf of Maine was nearly 5 degrees Fahrenheit above the long-term average during one 10-day stretch in August.
Scientists say warming waters means a threat to marine ecosystem, including lobsters and right whales.
The Gulf of Maine is a body of water that resembles a dent in the coastal Northeast, and it touches Maine, New Hampshire, Massachusetts and Atlantic Canada. Scientists previously identified the gulf as warming faster than 99 percent of the global ocean.
