Extraordinary global heating occurs in the Arctic

01 august 2022
According to latest studies, it is revealed that there is extraordinary rate of global heating in the Arctic, up to seven times faster than the global average.
The heating is occurring in the North Barents Sea, a region where fast rising temperatures are suspected to trigger increases in extreme weather in North America, Europe and Asia. The researchers said the heating in this region was an “early warning” of what could happen across the rest of the Arctic.
Recent years have seen temperatures far above average recorded in the Arctic. Some climate scientists have warned the unprecedented events could signal faster and more abrupt climate breakdown.
Sea ice is good at reflecting sunlight but is melting away. This allows the darker ocean below to absorb more energy. Losing sea ice also means it no longer restricts the ability of warmer sea waters to heat up the Arctic air. The more ice is lost, the more heat accumulates, forming a feedback loop. 
The research, published in the journal Scientific Reports, is based on data from automatic weather stations on the islands of Svalbard and Franz Josef Land. Until now, this had not been through the standard quality control process and made public. There was a very strong correlation over time between air temperature, sea ice loss and ocean temperature.
