Change In Antarctica

Antarctica is Earth’s southernmost continent.Antarctica is the coldest of Earth's continents and is a frozen desert with little precipitation. There are countless number of animals(including penguins, blue whales, orcas, colossal squids and fur seals), fungi(such as Cryomyces antarcticus, and Cryomyces minteri), plants and other organisms. Nonetheless, the biodiversity is consistently changing over past century and strongly affected by the climate change in recent years.
There are unique climate changes among the Antarctic region. These include the uptake of carbon dioxide by the Southern Ocean; the overturning circulation of the deep ocean; the balance between water storage and discharge in the main continental ice-sheet; changes in surface energy, mass and momentum exchange by ice masses; and energy transfer between all levels of the atmosphere to space. Their impacts include future greenhouse gas levels, sea-level rise, the variability and rate of change of climate, and changes in atmospheric composition. …show more content…

Many glaciers and ice shelves have retreated in recent years. 87% of glaciers along the west coast of the Antarctic Peninsula have retreated in the last 50 years with most of these showing accelerated retreat in the last 12 years.Recently it has been revealed that the collapsing in WAIS is unstoppable.
Meanwhile, the polar region-Antarctica-is particularly sensitive to small rises in the annual average temperature, they are sometimes referred to as "the canary in the coalmine" in that they show changes long before they can be seen elsewhere in the world. However, first it should be assumed that Global warming is real, and the average temperature in Antarctica region has risen for
