1. Ancient: -S ice covered on Earth: 16 million km2 (Antarctica constitute about 4/5)-The animal's Habitat in ice and snow area: + South Pole: the harsh climate, however, about 99% of the surface is covered by ice and air temperatures can be cold to water vapor in the atmosphere can also freeze into ice crystals, but the Southern Ocean surrounding Antarctica is the most abundant oceans on Earth about the category of biology. In this harsh climate is where the lives of so many animals: blue whale-the largest animals on Earth, the species of seals and several species of Penguin. Arctic: + animals in the Arctic there are many and widespread distribution. Animals include: continental North American deer species live in large herds, cows, wolves, bears, weasels, foxes ... Birds in the Arctic species: sparrows snow land, sea gull, Northern Fulmar, Black Forest Duck legs xira, geese and swans. There are many types of fish, and there are also seals, walrus, walrus and whales-Food: + The diet of most of the predators in Antarctica, including the blue whale is the species of krill. That the diet of krill is the plankton appear only from the deep waters. + Even the iceberg in Antarctica can also have life. The small ice fish escaping the carnivores in the niches of the ice. White Gull species also nest on floating ice, where it is often safer than is in the region of the main island.2. Now -Antarctic temperatures up: some areas of Antarctica are warming; especially strong warming in the Antarctic Peninsula recorded Peninsula. The study by Eric Steig published in 2009 showed that the first trend in average surface temperature across the continent increased slightly to about > 0.05° C in each decade from 1957 to 2006. This study also found that West Antarctica has warmed more than 0.1° C per decade within the past 50 years, and this warming is stronger in the winter and spring. This was partially offset by the cooling in East Antarctica. This is a sign of recognition are only from a study in Antarctica about warming due to human carbon dioxide emissions. -The ice collapsed: in 2002 the Larsen-B ice of the Antarctic Peninsula collapsed. Between 28 February and 8 March 2008, about 570km2 an area of ice of the ice Wilkins in the southwestern part of the peninsula collapsed, making the remaining area section 15000 km2 of ice also risk further erosion. The ice are played back with a width of about 6 km, before it collapses on 5/4/2009. According to NASA, the melting of surface ice of Antarctica takes place the biggest wide within 30 years the largest in 2005, when an area nearly the size of California to melt in a short time; This may be a result of the increase in temperature to 5° C. -Area of Antarctica is 14 triệukm2 freezes part of which is 13,720,000 km2. If the entire Antarctic ice melt, sea levels around the world would rise high about 70 m. -In September 2011, the ice covering the Arctic Ocean has melted and shrinks down to the lowest level in history, since the satellites observed 40 years ago.
