Among the main challenges confronting the Northern Canada is that the melting of their Permafrost and the destructions that it's causing to both living and non-living organisms. The term permafrost identifies a floor that stays "at or below the freezing stage for at least two consecutive years" (Bone Page 52). In Canada, nearly 76 percent of the property is occupied by the Arctic and Subarctic areas, which has a combination of continuous, discontinuous and sporadic permafrost. Continuous permafrost is mostly found from the Arctic and almost 80% of the ground remains frozen. On the flip side, discontinuous permafrost is mostly found from the subarctic and approximately 30 percent to 80 percent of the ground is frozen and eventually sporadic permafrost is seen in areas of Canada closer to the south and contains less than 30% of the earth eternally frozen. Nevertheless, in the last few decades, geographers have discovered that the normal temperature of the planet is growing quicker than it was previously, and it is a consequence of global warming. This in turn has led to the permafrost to start degrading, which has significant consequences on greenhouse gas emissions, artificial structure, vegetation, wildlife, and sea ice and the life span of the Inuit people in the North. Canada's population constitutes nearly 5 percent of the world population, but Canadians contribute approximately 2 percent of the world's greenhouse gas emissions. This results in permafrost melt which releases a lot of greenhouse gases, including CO2 and methane. When electricity from the sun reaches the Earth's surface, it absorbs a few, while discharging the remainder back to the outer space. However, not all of the published heat goes back into outer space. Instead, the molecules from the atmosphere, popularly called the greenhouses gases, traps thi...
