What is more terrible than the high temperature of 32℃ in the Arctic Circle?

Melting glaciers, rising coastlines, droughts and floods are threatening the lives of thousands of people.

Who is the master of the earth? Glacier sea Polar bear? Or human?

At present, hot weather is sweeping the world. A farmland in the Danish island of Xilan, which was green last July, has now turned brown. In Sweden, more than 10 forest fires caused by high temperature burned to the Arctic Circle.

The continuous high temperature in Japan has caused more than 22,000 people to be sent to hospital for heatstroke within a week, and 65 people died. The temperature in many places in China exceeded the local historical extreme value, and in July, the temperature in most areas was higher than normal 1-4℃. But compared with humans who can hide in air-conditioned rooms, the creatures in the Arctic Circle are even more difficult. According to the British "Guardian" report, on July 30th, the temperature in Norwegian Banneker in the Arctic Circle was as high as 32℃. Extreme weather warns people.

The direct impact of polar high temperature is the melting of sea ice in the Arctic Ocean.

As early as the late 1970s, satellites were used to record the sea ice in the Arctic Ocean. At that time, in summer, the sea ice coverage rate of the Arctic Ocean was usually above 50%.

In the past fifteen years, the sea ice coverage of the Arctic Ocean has decreased significantly.

According to the statistics of National Snow and Ice Data Center, the lowest sea ice coverage in the Arctic Ocean was 29% in 2007, and reached 24% in 20 12. In the five days from mid-October 2016165438+10, the sea ice area decreased by 19000 square miles, which is unprecedented.
