When PSCs form above Antarctica, chlorine reservoir molecules bind to the icy particles that make up the clouds. The change tends to produce fewer, larger liquid cloud droplets. For example, king crabs (Neolithodes yaldwyni), a predatory species, are already moving onto the Antarctic shelf and are likely to have significant impacts on other species (21). Screening fungi isolated from historic Discovery Hut on Ross Island, Antarctica for cellulose degradation.

Some other planets, such as Pluto, have such a huge axial tilt that large percentages of their surface experience polar night and day. Huge icebergs break away from the stationary ice and flow north to mix with warm water from the equator, producing currents, clouds, and complex weather patterns. Ask children to locate it on the map and explain that they’re going to create a presentation to inspire people to visit Churchill and have a ‘polar bear experience’. About 15 percent of the world's oceans are covered by sea ice during part of the year.

Antarctica has no indigenous population and there is no evidence that it was seen by humans until the 19th century. At the South Pole itself, the sun shines around the clock during the six months of summer and virtually disappears during the cold winter months. Rowland published a laboratory study demonstrating the ability of CFC's to catalytically breakdown Ozone in the presence of high frequency UV light. It also houses the International Arctic Science Committee (IASC), and hundreds of scientists and specialists who are in search of quality information about this yet-to-be-explored Polar Region.

The Antarctic is an isolated continent surrounding the South Pole. The Arctic has the only terrestrial mammals like musk oxen, reindeer, caribou, fox, hare, wolf, lemming, arctic foxes, and bears. There have been several studies comparing regularly visited colonies with those rarely in touch with humankind. As anyone living in colder areas of the United States or Canada knows. King penguins can be seen in numbers up to 500,000 on the Salisbury Plains of South Georgia. Polar bears are listed as threatened under the Endangered Species Act (ESA) because the sea ice on which they depend for hunting, feeding, reproduction, and seasonal movements is declining.

Greenland, for instance, is not as far north as Antarctica is south, so Greenland has longer, warmer summers, providing more opportunity for surface melting. But if people, corporations and governments fail to recognise and act on the problem, it is inevitable that their choices will one day catch up with them in a very unpleasant and unfortunate way. Surely a similar approach should be adopted for the Arctic, where not only is there a risk of spills but the threat of emissions to air, and in particular the deposition of black carbon, is also a major concern.

La Antártida, es una enorme superficie de hielo de la que solo emérgen algunas cumbres de más de 4000 metros de altura y que sólo cuenta con unas pequeñas áreas despejadas, los llamados desiertos antárticos, en los que la sequedad es tan extrema que no llega a formarse hielo. Blue skies, flat calm and glass like sea, with icebergs and bergy bits all around, seals, penguins and other birds, and humpbacks to finish off with.
