The Arctic is warming at a more rapid pace than previously thought — and four times faster than the world at large, according to research published Thursday in the journal Communications Earth & Environment. ¸ñ¿äÀÏ¿¡ ¹ßÇ¥ µÈ ¿¬±¸¿¡ µû¸£¸é ºÏ±ØÀº ÀÌÀü¿¡ »ý°¢Çß´ø °Íº¸´Ù ´õ ºü¸¥ ¼Óµµ·Î ¿Â³ÈµÇ°í ÀÖÀ¸¸ç Àü ¼¼°èº¸´Ù 4 ¹è ´õ ºü¸£´Ù°í Áö±¸¿Í ȯ°æÀÇ Ä¿¹Â´ÏÄÉÀÌ¼Ç Áö¿¡ ¹ßÇ¥Çß´Ù.Between 1979 and 2021, the Arctic warmed about four times as fast as the global average, significantly more than previous estimates of two or three times as fast, researchers found.1979³â¿¡¼ 2021³â »çÀÌ¿¡ ºÏ±ØÀº Áö±¸ Æò±Õº¸´Ù ¾à 4¹è ºü¸£°Ô ¿Â³ÈµÇ¾ú´Âµ¥, ÀÌ´Â ÀÌÀüÀÇ ÃßÁ¤Ä¡ÀÎ 2~3¹è ºü¸¥ °Íº¸´Ù ÈξÀ ´õ ¸¹Àº °ÍÀ̶ó°í ¿¬±¸¿øµéÀº ¹àÇû´Ù.Within the region itself there are also numerous variations in the pace of the warming — the northern Russian island chain of Novaya Zemlya is warming at seven times the global average, according to researchers from the Finnish Meteorological Institute.

As a result, when its sea ice melts, the increased portion of water contributes to further warming because it absorbs the sun¡¯s heat rather than reflecting it. ºÏ±Ø±ÇÀº ´Ù¸¥ Áö¿ª¿¡ ºñÇØ ³Ê¹« ¸¹Àº ºÎºÐÀÌ ¹Ù´ÙÀ̱⠶§¹®¿¡ ¿Â³ÈÀÇ À§ÇèÀÌ Æ¯È÷ ³ô´Ù. °á°úÀûÀ¸·Î, ÇغùÀÌ ³ìÀ» ¶§, ¹°ÀÇ Áõ°¡ µÈ ºÎºÐÀº žçÀÇ ¿À» ¹Ý»çÇϱ⺸´Ù´Â Èí¼öÇϱ⠶§¹®¿¡ ´õ ¸¹Àº ¿Â³È¿¡ ±â¿©ÇÕ´Ï´Ù.The impacts of this warming go far beyond the Arctic region, contributing to sea-level rise and the ocean¡¯s surface temperatures, which can tie into extreme weather events like hurricanes. The World Wildlife Fund describes the region as ¡°the world¡¯s refrigerator,¡± noting that when the Arctic reflects less heat, it can lead to both an increase in extreme heat and more cold snaps as it destabilizes the polar jet stream that blows around the Arctic Circle.
