Is there a difference in the impact of climate warming on the Arctic and Antarctic regions?

The Arctic is one of the most significant regions of global warming, and it is very sensitive to the response of global warming. In recent decades, various important environmental changes in the atmosphere, ocean and land in the Arctic region have affected all aspects of the Arctic environment, and are affecting ecosystems and biological resources and feeding them back to human society, thus affecting regional and even northern hemisphere economic activities. Changes in polar climate and atmospheric environment will also affect the global atmospheric circulation weather and climate. In the arctic cryosphere, a large amount of carbon is sealed, including elemental carbon and organic carbon, as well as solid natural gas hydrate (methane ice and combustible ice) and gaseous natural gas (oil and gas, coal seam and peat layer, etc.). ). The increase of Arctic gas temperature is more conducive to the survival and reproduction of fermentation bacteria and methanogenic microorganisms; In addition, due to the melting of arctic permafrost and sea ice, the area of natural swamps and wetlands in the Arctic region has increased. The freezing time of Arctic tundra is shortened; The increase of rivers, lakes and sea ice-free areas also leads to the increase of methane gas release in the Arctic.

Climate change in Antarctica is diverse in time and space. In recent decades, the significant warming in the Antarctic region mainly occurred in the Antarctic Peninsula in the southwest pole, which greatly exceeded the global average warming of 0.74 in the past 100. However, the warming of the East Antarctic continent is not obvious, and individual stations have obvious cooling trends in some years. Generally speaking, the temperature in Antarctica is rising, and the annual warming rate is close to 2. However, the main body of the Antarctic continent, especially the East Antarctic continental ice sheet, has not obviously warmed up, but has cooled down in some areas.
