How many degrees is the Arctic Circle?

The Arctic Circle refers to the dividing line between the northern frigid zone and the northern temperate zone, and the latitude is 66 34' north latitude, which is complementary to the intersection angle of Huangchi, and most of it is the Arctic Ocean.

The Arctic Circle refers to the area north of 66.5 degrees north latitude, with a total area of about 2 1 10,000 square kilometers, equivalent to 2.2 China. The land part includes Greenland, Northern Europe, Northern Siberia, Canadian Arctic Islands, Alaska and other places, with a total area slightly smaller than that of China. It is normal for such a large area to suddenly have a heat wave in a small place.

Do you have a fever in other parts of the Arctic? First, let's look at the weather in Svalbard with the data from the Yellow River Station in China (79 degrees north latitude).

In the Arctic, white is an eternal theme, and the appearance of any other color represents the destruction of the local ecology. This is because white will reflect some sunlight, reduce the earth's absorption of heat, and thus curb global warming.
