“Our changing summer climate isn’t all good or all bad when it comes to our natural resource economic sectors,” said state climatologist Sean Birkel, a University of Maine research professor and an adviser to the Maine Climate Council. In 2018, the Gulf of Maine Research Institute used computer modeling to predict Maine’s lobster industry would contract 40%-62% by 2030. This year, Maine’s average temperature first surpassed that threshold on May 15, the Maine Climate Office said. “Classic signs of a hot cow.”That’s a big investment for Maine’s struggling dairy farmers, whose numbers decline every year. That was a bit of a gamble, he said, but if electricity costs continue to rise, Good Shepherd should save money in the long run.
