    3 小时前  The Arctic sea ice melts every year from spring to early autumn. This year, the summer melt season is very strong. Currently, the Arctic sea ice extent and volume are near or at record lowest values in the modern records. That is largely due to the persistent high-pressure system over the Arctic Ocean.
