Greenhouse Gases are
created by cars, factories, and fossil fuels being burned. This has caused the
world to warm up, not by much but enough to affect Antarctica. The north-east
Antarctica peninsula has had a temperature change in the last 56 years. Flighty
six years ago the Antarctica air would warm up to 2.2 Celsius during the
warmest summer days. Now the Antarctica air warms up to 10 Celsius on the
warmest summer days. The shift of winds and the effects of the greenhouse gases
has recently caused ice shelf’s to break apart from Antarctica. The most reason
example has been the Larsen B ice shelf that broke apart in 2002. The cause of
the break-up was not only caused by the increase of temperature, but also
because of the strong Antarctic winds. The increase of temperature caused the
ice shelf to become thinner, making it vulnerable to the harsh Antarctic winds,
causing the ice shelf to break apart from the cold Antarctic.
(This is a Nasa Picture of the Larson B ice shelf. The Larson B ice shelf had an area of 3,250 square kilometers, or 1,250 square miles. The ice shelf was the size of Road Island)
Antarctica is not just
a sheet of ice it also contains a body of soil. That body of soil is seen as
the Antarctica Dry Valley. The low
humidity and the lack of snow and ice cover, makes the Dry Valley a visual
place to see the artic soil. Dry Valley contains the coldest, driest and
most oligotrophic soils making the Dry Valley soil known as arid soil. Arid
soil lacks water; preventing the growth of plants and animals. Arid soil lacks
vegetation; making Antarctica a dry, cold desert. Without the growth of animals
and vegetation it makes Antarctica a hard place to, not only live, but also for
organisms to be created.
(The Antartica Dry Valley; as you can see it is a dry, cold desert without vegetation)
