The idea of a seawall with giant gates to let in ships - that would close in advance of a major storm - first came up in a list of possibilities in a city report on preparing Boston for rising seas. The Globe reports several professors are spending a year studying the practicalities and costs of what would be one of the world's largest seawalls.

Stephen Gray writes about the conflict between Boston's Climate Ready Boston report, which projects which areas of the city face climate-change-related flooding and its Imagine 2030 report, which posits major development in several of those areas.

The Coast Guard introduces us to Joanne LaVigne Schroer, who was just a little girl when her father was assigned to a two-year spell as the Boston Light lighthouse keeper. And she recalls the ghost:

"When we went out to the island [in 1948] the second-floor bedroom that faces the light itself was always locked," Schroer recalled. "We had always heard that back in the 1800s there was a lightkeeper whose wife went a little stir crazy and killed her husband right around Halloween. Then, she wrote about it in her diary.

"Every October, we would hear these weird noises in that room," Schroer said. "One night, my mother jiggled the doorknob to see what was going on. All of a sudden, this black image came right through the door, down the hallway and then down the stairs into the kitchen. It was the lightkeeper's wife, and she had a big dog with her," Schroer attested. "I woke up in the middle of the night and there was that big dog sitting right in the room."
