Abstract
Global climate change has become a significant topic of study during recent years, as searches are made for trends in climate data, their causes and possible effects. Antarcüa is important as an indicator of change in global temperatures as climate models have predicted that the polar regions may show larger temperature increases than other areas due to feedback mechanisms which operate in the atmosphere-ice- ocean system (Raper et al, 1983). As temperatures increase, the sea ice area is predicted to decrease, reducing the albedo and resulting in further temperature rise. Thus any trends shown by Antarctica may act as early warning signals Of temperature changes on a global scale.

Long Term Temperature Trends at Scott Base, Antarctica
Gill-Fox, Deborah (2000)Temperature data from Scott Base, Antarctica, for the years 1957-1999 were analysed for long-term trends using linear regression. The annual mean temperature was found to be increasing at 0.0290C yr-l , and monthly and ... -
Long-term analysis of sea ice drift in the western Ross sea, Antarctica, at high and low spatial resolution
Farooq U; Rack W; McDonald A; Howell S (MDPI AG, 2020)© 2020 by the authors. The Ross Sea region, including three main polynya areas in McMurdo Sound, Terra Nova Bay, and in front of the Ross Ice Shelf, has experienced a significant increase in sea ice extent in the first ... -
Antarctica: Phantom of the Past or Canary in the Cage?
Pearn, Tim; Gill-Fox, Deborah; Gemmell, Michael; Hoar, Jenifer (2000)"A bridge to our future and a window on our past." This was a phrase used by President Clinton to describe Antarctica when he spoke at the International Antarctic Centre recently. It sums up the view that, in essence, ...
