Permafrost Melting and its Potential Impact in the North

One of the main challenges facing the northern part of Canada is the melting of permafrost and its damage to living things and non-organisms. The term permafrost means "ground freezing or subzeroing for at least two consecutive years" (bone page 52). In Canada, nearly 76% of the land is occupied by the Arctic and Subarctic regions. These are continuous, discontinuous, sporadic permafrost. Continuous permafrost layers are mainly found in the Arctic Circle, nearly 80% of the ground is still frozen.

The Arctic trees are facing unique challenges. At Scotty Creek in northern Canada, melting of permafrost is destroying trees. In this area, the growth area of ​​trees is limited, the land between the frozen areas of permafrost is mostly wetlands, trees can not grow due to root water. However, as the climate warms up, the ground gradually disappears from the bottom. As a result, trees lose the area where they can grow and are approaching the edge of the Permafrost Plateau, which can cause stress. In addition to the collapse of the edges, "They will collapse and will lose their roots," Anderson - Teiseira said. The availability of water is changing due to the specificity of melting and refreezing in these areas. This means that trees that do not collapse in permafrost are facing some combination of drought and flooding.

As the ice and permafrost melt in the Arctic Circle and the Atlantic Ocean continues to decelerate, warm air and water may move north from the Caribbean to relax the Arcadia maritime area and the temperate islands of the British Isles . Allow these areas to feel the full impact of their latitudes. Edinburgh is the same latitude as Moscow. Despite the number of the French Army being 691, 501 in 1812, Naples lost to "Winter General" in Moscow. Winter -40 ° C

As the widespread use of fertilizer increases the amount of greenhouse gases, the earth will have heat. When the surface warms up, the permafrost in the north begins to melt, releasing its carbon emissions into the atmosphere from the frozen microbial cemetery once. This in turn warms the planet further, and as a result more permafrost will melt. Some people do not believe that the rise in temperature is the result of global warming. Donald Trump has recently abolished many of President Obama 's environmental bills. Through a series of enforcement orders, the President reduced funds to many institutions like EPA and relaxed regulation of water and air pollution.
