4. In 2001, Tuvalu became a member of the United Nations and has since been vocal about the impacts of climate change on small island nations.
5. The nation is composed of nine islands: Funafuti, Nanumea, Nanumanga, Niutao, Nui, Vaitupu, Nukufetau, Nukulaelae, and Tuvalu's most populous atoll, Funafuti.

Review Questions

• How does Tuvalu's geographical features impact its vulnerability to climate change?
  • Tuvalu's geographical features significantly contribute to its vulnerability to climate change due to its low elevation and composition as a series of atolls. The highest point is only about 4.5 meters above sea level, making it susceptible to flooding from rising sea levels. The coral reefs surrounding these islands are also under threat from coral bleaching and ocean acidification caused by climate change, which jeopardizes the ecological balance and livelihoods of Tuvalu's inhabitants.
• Discuss the economic challenges faced by Tuvalu due to its geographical characteristics and environmental issues.
  • Tuvalu's economic challenges stem from its small size and limited resources coupled with environmental issues like rising sea levels and climate change. The economy relies heavily on fishing and agriculture, both of which are threatened by changing weather patterns and ocean conditions. Furthermore, Tuvalu's isolation limits trade opportunities and makes it dependent on foreign aid and remittances from its citizens abroad, exacerbating its economic vulnerability.
• Evaluate the role that Tuvalu plays in international discussions on climate change and its significance for other low-lying island nations.
  • Tuvalu plays a critical role in international discussions on climate change by serving as a vocal advocate for vulnerable nations facing similar threats. Its unique situation highlights the urgent need for global action to mitigate climate change impacts on low-lying island nations. By sharing its experiences and challenges at international forums like the United Nations Framework Convention on Climate Change (UNFCCC), Tuvalu raises awareness about the plight of affected nations and pushes for policies that prioritize their survival and adaptation efforts in a rapidly changing environment.
