World Geography 10 Marks

How are climate change and the sea level rise affecting the very existence of many island nations? Discuss with examples.

Directive: Discuss 10 marks
Introduction

Climate change, marked by rising temperatures and extreme weather, combined with sea level rise from thermal expansion and ice melt, presents an existential threat to low-lying island nations, particularly Small Island Developing States (SIDS).

Body
Impacts on Island Nations
  • Coastal erosion, permanent land inundation, and saltwater intrusion contaminating freshwater and arable land.
  • Losses in agriculture, fisheries, and tourism; damage to critical infrastructure; leading to forced displacement and migration.
  • Loss of territory, sovereignty, cultural heritage, and national identity for entire populations.
Case Studies

Nations like Tuvalu, Kiribati, Maldives, and the Marshall Islands exemplify this crisis, facing severe land loss, developing relocation plans, and advocating for global climate justice.

Conclusion

Their plight highlights the urgent need for global climate action, adaptation, and international support to preserve their existence and unique heritage.

Suggested structure

  • Introduction: Defining Climate Change, Sea Level Rise, and the Vulnerability of Island Nations

  • Conclusion: Summarizing the dire threat and need for global action

Key points

  • Climate change (temperature rise, extreme weather) and sea level rise (thermal expansion, ice melt) are direct threats to low-lying island nations.

  • Physical impacts include coastal erosion, permanent inundation of land, and saltwater intrusion contaminating freshwater sources and arable land.

  • Socio-economic impacts involve loss of agriculture, fisheries, and tourism, damage to critical infrastructure, leading to forced displacement and migration.

  • Existential threat encompasses loss of territory, sovereignty, cultural heritage, and national identity for entire populations.

  • Specific examples like Tuvalu, Kiribati, Maldives, and Marshall Islands are facing land loss, relocation plans, and calls for climate justice.

  • The inherent vulnerability of Small Island Developing States (SIDS) due to their geography and limited resources exacerbates these impacts.

Common mistakes

  • Lack of specific examples of affected island nations.

  • Failing to connect impacts directly to the 'very existence' aspect, instead providing general environmental damage.

  • Over-focusing on the causes of climate change rather than its effects on islands.

  • Not distinguishing between impacts of general climate change (e.g., extreme weather) and specific sea level rise.

Difficulty: Medium — While the topic is common, a good answer requires specific examples and a nuanced discussion of how these impacts threaten 'existence' beyond just general environmental damage, linking to sovereignty, culture, and forced migration.
