Cod hanging to dry on wooden racks in front of the mountain Olstinden, Moskenes, Lofoten, Norway. Overfishing and climate change mean that there is less and less cod. Norway's fishing tradition is closely linked to the history of Arctic cod. Cod needs cold temperatures. A rise of 1 degree in the water would cause a decrease in the yield of cod stocks of up to 21% and in the case of 2 degrees Celsius, of up to 42%, with a forecast that fisheries will be reduced by half. in the year 2050. The polar cod is threatened by climate change and is highly vulnerable to oil spills. The iskaten is the transition strip between the ice-free sea and the sea covered by an icy layer (solid and liquid). This border is constantly changing. For this reason, until now, it was defined as the area with a 30% probability of having ice in April, according to records for the period between 1967 and 1989. Even so, the retreat of the ice pack due to global warming has led to rethink these limits, which has caused the conflict between the interests of the industry and the Norwegian government and the protests of environmentalists and scientists.
