Spinning Yarn in the Antarctica Climate; The
Collapse of Antarctica Glaciers
The combination of cold air, high winds, and blowing snow makes the
Antarctica climate the severest in the world. Spinning yarn in this climate can be very difficult. Severe
low temperatures vary with latitude, elevation, and distance from the ocean; there are three main Antarctica
climate areas: East Antarctica is colder than West Antarctica because of its higher elevation; The Antarctic Peninsula has the most moderate climate; higher temperatures occur in January
along the coast and average slightly below freezing.
The Antarctica climate has at the centre of the landmass a very cold average annual temperatures of -50C to
-60C. Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in
much of the rest of the world. Spinning yarn in these temperature would be a real challenge.
Since the Antarctic Peninsula is the most northern part of Antarctica, extending to within 1000km of South
America, it has the most moderate of the three Antarctica climate regions and therefore the most variety of
Antarctic Animals (penguins, seals, whales, fish, krill etc), plants (grasses, lichen, mosses etc) and other life forms. The Antarctica
climate does not allow extensive vegetation.
Antarctic Continental Coastal regions have a polar climate with a short summer averaging above freezing, and
much higher precipitation, and strong storms. The light colour of Antarctica's snow and ice reflects most of the
sun's radiation (warming rays) and serves to worsen an already harsh climate. Spinning yarn to produce warm
garments would seem like a good idea!
The Antarctica climate is an important influence on day to day weather in the
Southern Hemisphere, and on world weather and climate patterns, the circulation of ocean currents and
atmospheric winds. It is this influence that places Antarctica at the heart of the debate on climate change
and why it has become the premier location in which to study the effects of global warming.
The properties of the ice, of dust trapped in the ice, and even of air bubbles trapped in the ice give valuable
information about the earth's climate at various times in the past. It is long-term Antarctica climate information
stored in the layers.
Most of the continent's icy mass has so far proven largely impervious to climate change, being situated on solid
rock; its deep interior is actually growing in volume.
The effects of Antarctica climate change vary from migrations of seal and penguin populations to other parts of
the continent, to abrupt changes in the glacial landscape.
Perhaps most vulnerable to the effects of Antarctica climate change are the continent's wildlife populations.
The carving off of ice shelves and the collapse of glaciers are part of Antarctica’s natural cycle, but man-made
climate change could accelerate the processes. Antarctica climate weather is a lesson in extremes.
