During the Arctic winter, when the sun hides from October to March, the average temperature in the frozen north is around $-20° \mathrm{C}$. But in 2020, the Arctic went through much h
56 temperatures.
On February 20, 201
8, the temperature in Greenland climbed a
56 $0° \mathrm{C}$ and it stayed that high for over 24 hours. Then, on February 24, the temperature in northern Greenland r 58 $6° \mathrm{C}$.
Weather conditions that make temperature rise like this usually happen every ten years. However, the last such increase in temperature t
59 place in 2016.
This means a lot. As a r
60 , the climbing Arctic temperatures make the sea ice melt. In fact, sea ice cover in the Arctic is melting f
61 than usual. Without a great deal of cool sea ice, warm air brought to the Arctic can go further to the land. The air can stay warmer and l
62 too. This makes more ice melt.
Overall, the earth is warming—the past five years become the hottest years on r
63 —and the Arctic is warming twice as fast as anywhere e
64 on the earth.
It is predicted that Arctic summer ice will totally disappear by around 2060. But the Arctic may face summers w
65 ice sooner than expected.
