Explain the threat of sea-level rise to Pacific island nations and evaluate current economic and environmental issues across Oceania.
Low-lying Pacific island nations such as Tuvalu, Kiribati, and the Marshall Islands face an existential threat from climate-change-driven sea-level rise, since much of their land sits only a few feet above current sea level -- making these nations some of the most vocal participants in global climate diplomacy. Coral reef bleaching, caused by warming and increasingly acidic oceans, threatens the Great Barrier Reef and other reef ecosystems the region depends on for fishing income and tourism revenue alike.
Australia's economy relies heavily on mineral and resource exports (iron ore and coal especially) and agriculture, alongside a large services sector, giving it one of the world's highest standards of living. Tourism is a major economic pillar across the Pacific Islands, but this dependence makes island economies vulnerable to external shocks, such as a global pandemic that halts international travel. Ongoing efforts at reconciliation between Indigenous peoples and their national governments continue, focused on land rights, historical treatment, and cultural recognition.
Mastery looks like: They can explain why sea-level rise is an existential issue for specific low-lying Pacific nations, describe coral bleaching's economic impact, and connect tourism dependence to the same vulnerability pattern studied in other regions.
Common stumbles: Treating climate change's impact on Oceania as abstract rather than tied to specific, measurable elevation data; forgetting to connect tourism dependence back to the commodity-dependence pattern studied earlier in the course.
