Standing on the seawall after hauling lobster traps for about 12 hours on a foggy day this August, Drew Eaton says he's making plenty of money to cover the boat loan. He's unloaded 17 crates, each carrying 90 pounds of lobster, for a total haul of nearly $5,500. It's a pretty typical day for him.

Eaton belongs to a new generation of Maine lobstermen who are riding high, for now, on a sweet spot of climate change. Two generations ago, the entire New England coast had a thriving lobster industry. Today, lobster catches have collapsed in southern New England, and the only state with a significant harvest is north in Maine, where the seafood practically synonymous with the state has exploded.

The thriving crustaceans have created a kind of nautical gold rush, with some young lobstermen making well into six figures a year. But it's a boom with a bust already written in its wake, and the lobstermen of the younger generation may well pay the highest price. Not only have they heavily mortgaged themselves with pricey custom boats in the rush for quick profits, they'll also bear the brunt of climate change – not to mention the possible collapse of the lobstering industry in Maine as the creatures flourish ever northward.
