context_page_description: Antarctica is the Earth's southernmost continent. It is on the South Pole. It is almost entirely south of the Antarctic Circle. Around Antarctica is the Southern Ocean. It is the fifth-largest continent in area after Asia, Africa, North America, and South America. About 99% of Antarctica is covered by ice. This ice averages at least 1.6 kilometers thick.
  Antarctica is the coldest, driest and windiest continent. It is also, on average, the highest of all the continents. Antarctica is considered a desert. It has yearly precipitation of only 200 mm near the sea and far less inland. No humans live in Antarctica permanently. However, about 1,000 to 5,000 people live through the year at the science stations in Antarctica. Only plants and animals that can live in cold live there. The animals include penguins, seals, nematodes, tardigrades and mites. Plant life includes some grass and shrubs, algae, lichen, fungi, and bacteria.
  The first known sighting of the continent was in 1820. Antarctica was mostly forgotten for the rest of the 19th century. This was because of its hostile environment, few resources, and isolation.
context_section_description: For a long time, people had believed that there was a great continent in the far south of Earth. They thought this Terra Australis would "balance" the lands in the north like Europe, Asia and North Africa. People have believed this from the times of Ptolemy (1st century AD). He suggested this idea to keep the balance of all known lands in the world. Pictures of a large land in the south were common in maps. In the late 17th century, people discovered that South America and Australia were not part of the mythical "Antarctica". However, geographers still believed that Antarctica was much bigger than it really was.
  European maps continued to show this unknown land until Captain James Cook's ships, HMS Resolution and Adventure, crossed the Antarctic Circle on 17 January 1773, in December 1773. They crossed it again in January 1774. In fact, Cook did come within about 75 miles (121 km) of the Antarctic coast. However, he was forced to go back because of ice in January 1773.
  The first confirmed sighting of Antarctica were by three different men. According to different organizations, ships captained by three men saw Antarctica in 1820. The three men were Fabian von Bellingshausen (a captain in the Russian Imperial Navy), Edward Bransfield (a captain in the Royal Navy), and Nathaniel Palmer (an American seal hunter out of Stonington, Connecticut). The first recorded landing on mainland Antarctica was by the American sealer John Davis. He landed on West Antarctica on 7 February 1821. However, some historians are not sure about this claim.
  People began discovering different parts of Antarctica and mapping them. This was slow work because they could only work in the summer. At last a map was made, and people began to talk about exploring the land, not only the sea. However, this would have been very hard work. They would have to break through the ice that was around Antarctica. Then they would have to land on it and bring in enough things to live on while they explored the land.
  The first serious exploration of the Antarctic land was the Nimrod Expedition led by Ernest Shackleton in 1907–09. They were the first to climb Mount Erebus and to reach the South Magnetic Pole. Shackleton himself and three other members of his expedition made several firsts in December 1908 – February 1909. They were the first humans to cross the Ross Ice Shelf, and the Transantarctic Mountain Range (via the Beardmore Glacier). They were the first to set foot on the South Polar Plateau.
  Robert Falcon Scott, the most well known of all of the explorers, wanted to be the first man to reach the South Pole. At the same time, another team from Norway lead by Roald Amundsen started. They both raced each other to the South Pole, but in the end Amundsen won because he had made a good use of his sleigh dogs. Scott had used ponies and motor sleds, but when he got to the South Pole he found a message from Amundsen, showing that he had beaten Scott.
  On his way back, Scott and three companions met a blizzard and froze to death while waiting for it to finish. The people who found him eight months later also found his records and diary, which he had written to the day he died.
  Climate change and global warming are showing effects in Antarctica, particularly the Antarctic Peninsula.
