How large is antarctica, how much of it is ice (compared to global) and how much of global freshwater is it
14million km, 99% glacial ice (nunataks aren’t), 90% world’s ice, 70% global freshwater
Section of Antarctica, average hight (with mountain height), winds
East Antarctica (greater area) and West Antarctica separated by Transarctic mountains, average height 2,300m, Mount Vinson 4,892 metres, kabatic winds 200mph
Why is it known as a polar desert
Annual precipitation <50mm
Antarctic conevrgence
Cold Southern Ocean water sinks below warm water to create highly productive marine zone
Threats to antartica
Climate change, Fishing/whaling, Mineral resources, Tourism/scientific research
Climate change in Antarctica threat
Peninsula has warmed by 3C in the last 50 years, with the Thwaites Glacier at risk of collapsing to rise sea levels by 63cm. Positive feedback loops from albedo created and ocean acidification is caused by the South ocean absorbing 30% atmospheric co2
Examples of wildlife affected in climate change
Adeline penguins declining due to need for stable ice to breed, invasive plant species colonise
Fishing/whaling threat
200,000 tonnes of Krill harvested annually could causes food chain failure for seals/penguins. Illegal fishing such as 24% of Patagonian Toothfish was illegally harvested in 2004.
Mineral resources threat
antarctica contains vast deposits of coal, iron, oil. Mining infrastructure would destroy habitats and an oil spill would not decompose for decades.
Tourism/scientific research threat
120,000 annual tourists create ‘honeyspots’ where plants/animals are disturbed. MS explorer crash left a mile long fuel spill. 82 research stations pollute with waste and chemicals. Infrastructure development like the 1,000 mile long US ‘Ice Highway’
Protection treaties/projects for Antarctica
Antarctic Treaty, Madrid Protocol, International Whaling Commission, UN agencies
Antarctic Treaty and features
Ensured peaceful purposes, freedom of scientific research and froze territorial claims. All areas open for unannounced site inspections with personal acting under home nation jurisdiction
Antarctic Treaty evaluation
Successful international agreement with 60+ years of peace. Unanimous consensus means 1 country can veto protection, no hard legal penalties
Madrid Protocol and features
Viewed Antarctica as a nature reserve for peace/science and banned all mining. EIA means activities are assessed to mitigate environmental damage
Madrid protocol evaluation
Fully comprehensive ‘umbrella’. Subject to review in 2048, EIA more administrative (allowed Ice Highway)
International Whaling Commission and features
Suspended all commercial whaling to conserve whale stocks, Southern Ocean Sanctuary prohibits whaling for 50million km
International Whaling Commission evaluation
Effectively ended large scale commercial whaling. Voluntary with Japan leaving without penalty, loophole of ‘scientific research’
Role of UN agencies and features
UNEP coordinates and promotes policies relating to climate change
UN agencies evaluation
Work on projects like Paris agreement project that indirectly protects Antarctica. Little direct influence as legislation does not cover Antarctica.
Antarctic and Southern Ocean Coalition (ASOC) NGO
Observer status of the ATCMs to allow monitoring and a unified voice. Coalition of 30 NGOs like Greenpeace
Roles of NGOs with examples
Guardians/Watchdogs of ATS (blocked a scheme for the Madrid protocol), Technical/Scientific advisers, Partners in conservation (Ross Sea MPA), Visionaries/Long term strategies (World Park Antarctica)
Methods of NGOs
Independent data collection to validate government, Review Environment Evaluations (Ice Highway), Direct monitoring (Sea Shepheard Conservation Society monitor whaling)
Evaluation of NGOs
No legal enforcement power, unanimous consensus reduce influence, limited by donor priorities/resource access
Impact of global governance on Antarctica
Political stability/peace, Primary industry of science, Environmental regulation
Impact of global governance on places elsewhere with examples
Climate regulation through heat sink, Sea level management (6 metre sea level rise if melting, 70% worlds freshwater), Marine sustainability (krill for food security)
Impact of global governance on citizens
Educational/knowledge benefits from science, Long term resource security, Security/safety by preventing war, Economic opportunities like extreme tourism
