This warming differential between the poles and the tropics is known as Arctic (or polar) amplification. It is typically measured as the ratio of polar warming to tropical warming. Effects of Arctic warmingOne of the most significant effects of Arctic amplification is the weakening of west-to-east jet streams in the northern hemisphere. Here we look at the larger body of evidence that supports the relationship between Arctic warming and slowing jet streams. Global climate models project stronger surface warming in the Arctic than the Antarctic under climate change.
