It is situated over the South Pole almost entirely south of latitude 66°30’ south (the Antarctic Circle). Less than a decade ago, most populations of polar bears were considered healthy, even growing. Maritime polar air forms over oceans at high latitudes. The remainder is exposed barren rock. Antarctica is generally mountainous, with elevations typically ranging from 2,000 to 4,000 meters (6,600 to 13,200 feet). Although several countries have laid claim to various portions of Antarctica, it is governed by the 1958 Antarctic Treaty, which establishes the continent as a peaceful and cooperative international research zone.

There are large land mammals such as polar bears, musk oxen and caribou. L'Antartide è il continente più meridionale della Terra, comprendente le terre e i mari che circondano il Polo Sud, tra i 66 e i 90 gradi di latitudine sud. This translates to their population doubling every five years. One of the witnesses to this particular event, the expedition photographer, took a number of photographs of the object. With the NSF Phase II CCEP award, we plan to implement our vision to use novel educational approaches and fascination with the changing polar regions in order to engage adult learners and inform public understanding and response to climate change.

Sea ice will thin in some places and disappear in others. some scientists now see signs of a possible link between global warming and global cooling. We found that northern hemisphere temperature and Greenland temperature changed synchronously at periods of ∼20 years and 40–100 years.

Within the Polar World (and beyond). the polar region has more fresh surface water than any other part of the world. however. The PV images above illustrate the lack of large-scale waves in the southern hemisphere during the mid-winter period. Receding ice allows ships to explore further south. This allows them to hover continuously over one position on the surface. The abiotic factors of Antarctica are its low temperatures, small amount of precipitation and polar ice .

Earlier melting of the sea ice in Hudson Bay is the major driving force behind the population decline, but a continuing unsustainable harvest of seals has aggravated the situation. Another is that the ocean circulation transfers significant amount of heat from low to higher latitudes, helping the climate system to attain an approximate steady state condition. In this section we bring forward key findings that outline how climate change may impact on soil invertebrate communities of the polar regions, information that is useful for understanding potential future states.

This research is conducted cooperatively with the University of Delaware, the University of Montana Missoula, and the University of Alaska Fairbanks. Merchant ships swinging low along these circle-routes would come across small, isolated Antarctic islands, many for the first time. Observations of chloroflourocarbons and of stratospheric hydrogen chloride support the view that international actions are reducing the use and release of ozone depleting substances (WMO, 1999; Anderson et al., 2000).
