Warming of the Arctic will lead to the fact that more than 70% of the Siberian tundra area will disappear by the middle of this year.
Scientists have created a computer model thatestimates the entire 4,000 km expanse of the Siberian tundra. It takes into account the life cycles of individual trees. As the region's permafrost cover continues to melt, it will release huge amounts of greenhouse gases into the atmosphere. They are usually “sealed” in the ground, and if they are released, it will potentially accelerate warming throughout the world.
Under a scenario where carbon emissionswill fall to zero by 2100 and global temperature rise will remain below 2 °C, by 2500 only 32.7% of today's tundra will remain. The region will be divided into two mini-tundras: one in Chukotka in the Far East, and the second on the Taimyr Peninsula in the Far North.
Warming in the Arctic in the recentdecades, progress was about twice as fast as in the rest of the globe. According to the National Snow and Ice Data Center, air temperatures in the Arctic region increased by almost 4 °C between 1960 and 2019. This reduced the sea ice cover and also affected the land in the region.
