Ocean blob brings tropical fish to B.C. coast

Something unusual is happening off the coast of British Columbia. Fish species normally found in the warm waters of the tropics are finding their way north — and a blob is being blamed... scientists have been tracking a large mass of water in the Pacific Ocean that is 1,000 kilometres long and at least 2 C warmer than usual. The blob now stretches from Mexico to Alaska and scientists say heat is being trapped within it, making it feel like home for fish used to warmer climes.
