A study from University of British Columbia published in ICES Journal of Marine Science concludes that global warming will drive fish toward poles, leading to potential disappearance of large number of fish from the tropics by 2050. While food security issues may arise in tropical countries, many of which rely heavily on fish as main source of protein, fish movement to the poles may generate opportunities for fisheries in the Arctic. This study follows on a previous research from UBC published in Nature in May 2013. More details on CBC website.
