When he finished school, Daragh McGuinness knew he wanted to join a fishing crew but now, at 23, he fears climate change may kill off the industry that has sustained his family for generations.

"It's a massive problem," he said in the pilothouse of the Atlantic Challenge trawler, where he works as a deckhand, docked in the port of Killybegs in northwest Ireland.
