LONDON -- The seas around Britain are starting to teem with fish species once deemed exotic as climate change raises water temperatures, forcing the former dominant occupants to flee northward toward the Arctic and opening the way for those from the hotter south, according to marine and fisheries scientists.

..."People have started calling the North Sea the crucible of climate change. It has warmed by about a degree Celsius over the last 50 to 100 years, which is something like six times faster than pretty much any marine area around the world," John Pinnegar, program director of the Marine Climate Change Centre at the government's Centre for Environment, Fisheries and Aquaculture Science, told ClimateWire.
