Antarctica Case study Flashcards
1
Q
Climate
A
- coldest place on earth
- average temperature is -49 degrees
- lowest temperature recorded was -89
- considered a desert due to its dry climate
- average under 50mm rainfall inland
- average winds are 60-70mph
- 6 months dark, 6 months light
2
Q
Natural resources
A
- marine life
- fossil fuels
- oil reserves
3
Q
Vulnerability as a Global Common
A
- high demand for its resources
- vulnerable to climate change
4
Q
Name 4 major threats to Antarctica
A
climate change, fishing/whaling, resource exploitation, tourism/research
5
Q
How does climate change pose as a threat to Antarctica?
A
- warmers temperature melt ice sheets, which cause sea levels to rise
- CO2 stored in the ice sheets is released into the atmosphere
- the albedo effect is reduced
- certain marine species have declined due to changing sea temperatures
6
Q
How does Fishing and Whaling pose as a threat to Antarctica
A
- overfishing causes marine life to go extinct
- up to 120,000 tonnes fished annually
- currently bans on whaling, due to their endangered populations
7
Q
How has resource exploitation posed as a threat to Antarctica?
A
- oil exploitation disrupts the natural habitat
- oil spills cause great damage to Antarctica
8
Q
How has tourism and scientific research posed as a threat to Antarctica?
A
- travel to and from Antarctica has greatly increased fossil fuel emissions
- cruise ship crashes destroy sea ice
- research bases can disrupt the environment if not handled properly
