Rising surface temperatures drive back winter ice in Barents Sea, Rutgers researchers find

Rising sea-surface temperatures in the Barents Sea have led to a decline in winter ice cover over the past 26 years. The study found that warming ocean temperatures, driven by increasing greenhouse gases, are the primary cause of this trend. In contrast, Arctic pack ice is expected to continue its rapid decline due to atmospheric effects.
