.

Including 2019, the linear rate of decline for December ice extent is 3.6 percent per decade. This corresponds to a trend of 46,500 square kilometers (18,000 square miles) per year, which is roughly twice the size of the state of New Jersey. Over the 41-year satellite record, the Arctic has lost about 1.9 million square kilometers (734,000 square miles) of ice in December, based on the difference in linear trend values in 2019 and 1979. This is comparable to the size of Alaska and California combined.
