The warming of the Antarctic Peninsula is causing changes to the physical and living environment of Antarctica. The distribution of penguin colonies has changed as the sea ice conditions alter. Melting of perennial snow and ice covers has resulted in increased colonisation by plants.
What is the biggest threat to Antarctica?
The main threats facing Antarctica:
- 1 – Climate change / Global warming, resulting in a warming of the sea and loss of sea ice and land-based ice, this is greatest long-term threat to the region.

Why is Antarctica not warming up?
The latest study also found that for the period 1969 to 2000, there has been slight cooling over East Antarctica. So what is going on? The cooling is due to a strengthening of the circular winds around the continent, which prevent warmer air reaching its interior.

Why is gold not found in Antarctica?
Inland temperatures around Antarctica can get to be around -100 degrees Fahrenheit. This could make mining difficult and even deadly. Plus, the fact that so many deposits are found under many miles of ice only makes the possibility of mining in the region even harder to handle than people might expect it to be.
