"Since 1900, the Arctic has warmed on average by 2 degrees Celsius, 3.6 degrees Fahrenheit, fueled by the heat-trapping gasses from burning fossil fuels. That’s playing out several key ways.
Fish stocks are moving further north as species like cod and redfish seek cold refuge from warming oceans. Many Arctic nations count on fishing, but right now, there is a moratorium on fishing in the Arctic for at least 15 years. After that, the waters could become a lot more crowded than they are now: 'I think the boats will follow eventually if that moratorium is lifted,' said Mia Bennett, an assistant professor of geography at the University of Washington."
