In the Arctic, warming is twice as high as in other parts of the world. This leads to plants having a longer growing period, and it is good that the plant's growth absorbs carbon dioxide from the atmosphere. However, the warming of the climate has also thawed the carbon in the permafrost, which is also released into the atmosphere. Permafrost contains three to seven times more carbon than tropical forests. Thawing the frozen soil layer will lead to more carbon dioxide and methane being released into the atmosphere. They will warm the climate and thaw larger permafrost. 
Assistant researcher Suna Tauli of Woods Hole Research Center and his colleagues designed the first experiment from winter warming to determine the net profit and loss of carbon emissions. The results showed that the benefits of the growing season could not make up for the thawing of carbon from permafrost. Emissions. Natalie said: "Our results show that although carbon uptake during the growing season has increased, which is in line with the changing trend of modern "greening" tundra, winter warming and thawing of frozen soil also increase carbon emissions. The carbon loss doubles every year."
Scientists estimate that permafrost will decline by 30% to 70% in the next century and only limited carbon will be stored in these frozen soils. Dr. Natalie: "The only way we can accurately predict future climate warming is to understand the response of plants and microorganisms. This study is the first time to simulate the entire ecosystem warming in the Arctic including frozen ground. A series of climate changes, including degradation."
