Antarctic Climate
Antarctica has six months of daylight and six months of darkness. The earth revolves around the sun and tilts on it's axis. During the winter, Antarctica is tilted away from the sun, causing it to be dark. For the half of the year that is summer, Antarctica is facing the sun and getting more of its direct rays.The lowest temperature ever recorded in Antarctica was -129ºF. The warmest temperature ever recorded in Antarctica was 59ºF. The average summer temperature is 20ºF. The average winter temperature is -30ºF.
The highest wind speed ever in Antarctica was when the wind was moving at five meters per second. The wind is an important factor in making Antarctica cold. The wind can lower the temperatures of Antarctica by at least ten degrees.
The Antarctic is colder than the North Pole because it warms up faster and it cools down faster. Antarctica gets warmer faster than the Arctic because the Ocean water carries heat from the equator to the poles. The land of Antarctica heats up faster than the waters of the Arctic.

Climate Change
Antarctica and its surrounding ocean are dominated and shaped by the presence of snow and ice which, while themselves controlled by the climatic regime and very sensitive to climate change, also influence and provide major feedbacks to the global climate system.
Many globally significant processes are driven by the unique climate and geography of 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. Understanding these processes is vital for understanding and predicting climate and environmental changes and their impacts. These impacts include future greenhouse gas levels, sea-level rise, the variability and rate of change of climate, and changes in atmospheric composition. The latter includes the stratospheric 'ozone hole', which affects life in Southern Hemisphere nations.
