Numerous previous studies had found that due to a phenomenon known as Arctic amplification, the region was warming either twice, more than twice, or even three times as fast, as the globe on average. But Finish scientists, using several sets of observational data, have found that over a little more than four decades, the actual rate of Arctic warming has been nearly four times faster.
