Spinning Yarn in the Antarctica Climate;
The Collapse of Antarctica Glaciers
The combination of cold air with high winds and blowing snow makes Antrarctica
climate the most severe in the world. Spinning a Yarn in this climate can be very difficult.
Severe low temperatures vary with latitude, elevation and distance from the ocean; there are theree main
Antarrctica climate areas: East Antarctica is colder than West Antarctica because of its higher elevation: the
Antarctic Peninsula has the most moderate climate; higher tempratures occur in January along
the coast and average slightly bleow freezing.
The Antarctica climate has at the centre of the landmass a very cold average annual temperature 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 temperatures would be a real challenge.
Since the Peninsula is the most northern part of Antarcica, extending to within 1000 kms of South America, it
has the most moderate of the three climate regions and therfore the most variety of Antarctic animals (penguins, seals, whales, fish, krill etc), plants (grasses, lichens, mosses etc) and other life forms. The Antrarctic
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 Antrarctica's snow and ice reflects most of the
sun's radiation (warming rays) and serves ro to worsen and already harsh cliimate. Spinning Yarn to produce
garments would seem to be a good idea!
The Antarcica climate is an important influence on day to day weather in the Southern Hemosphere as well as on
world weather and climate patterns, the circulation of ocean currents and the atmospheric winds. It is this
influence that places Antarctica in 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
that is stored in the layers.
Most of the Continent's icy mass has so far proven to be 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 the most vulnerable to the effects of Antarctica Climate change are the continent's wildlife
populations. The carving off of ice shelves and the collapes of glacierr are a natural part of Antarctica's cycle,
but man-made climate change could accellerate the process. Antarctic climate weather is a lesson in extremes.
