"Each summer for the last two decades, Jim Parker has readied his small whale watch boat, and made a business out of ferrying tourists out into the cool blue waters of the Gulf of Maine.
For years, it was steady work. The basin brimmed with species that whales commonly feed on, making it a natural foraging ground for the aquatic giants. Whales would cluster at certain spots in the gulf, providing a reliable display for enchanted visitors to the coastal community of Milbridge, Maine.
But lately, the whales have been harder and harder to find. Waters in the gulf have been warming, sending the whales' food supply searching for cooler temperatures. The whales have gone with them. Some days this summer, Parker says he didn't spot a single one. Business fell 20%, forcing him to cut his season short."
