Climate Change and Sea Level Rise: Green Plan 2030

Students analyze Singapore's vulnerability as a low-lying island and the strategies outlined in the Green Plan 2030.

Key Questions

  1. Explain why climate change is an existential threat to Singapore.
  2. Differentiate the infrastructure being built to protect against rising sea levels.
  3. Evaluate how a small city-state can contribute to global climate goals.

Period: Semester 2

About This Topic

Climate change is an existential threat to Singapore, a low-lying island where much of the land is less than 15 meters above sea level. This topic covers the risks of sea-level rise and extreme weather, and the multi-billion dollar infrastructure projects, like polders and sea walls, being built to protect the nation. It also explores the Singapore Green Plan 2030 and the push for a low-carbon future.

This topic is a study in 'long-term resilience.' It connects to the MOE syllabus by examining 'global challenges' and 'environmental sustainability.' Students benefit from active learning by 'modeling' the impact of a 1-meter sea-level rise on a map of Singapore and proposing adaptation strategies.

Active Learning Ideas

Watch Out for These Misconceptions

Common MisconceptionClimate change will only happen in the far future.

What to Teach Instead

Singapore is already experiencing more intense rainfall and hotter days. A 'weather data' comparison activity (comparing 1970 to today) can help students see that climate change is a current reality, not just a future threat.

Common MisconceptionWe can just build higher walls to solve everything.

What to Teach Instead

Walls are only part of the solution; we also need 'nature-based' solutions like mangroves and to reduce our own carbon footprint. A 'holistic defense' brainstorming session can help students see the variety of strategies needed.

Frequently Asked Questions

Why is climate change an existential threat to Singapore?
As a low-lying island, Singapore is highly vulnerable to rising sea levels, which could flood large parts of the city. It also faces risks from more frequent and intense extreme weather, such as heavy rainfall causing floods and prolonged heatwaves that affect health and energy use.
What is Singapore doing to protect against sea-level rise?
Singapore is investing over $100 billion in long-term coastal protection. This includes building sea walls, raising the minimum level for newly reclaimed land, and exploring innovative engineering like polders (land reclaimed from the sea that is protected by dikes).
How can active learning help students understand climate change?
By 'modeling' sea-level rise on a map, students see the direct threat to their own homes and neighborhoods. This makes the abstract global issue of climate change a personal and national priority, helping them understand why the government is investing so much in long-term infrastructure.
What is the Singapore Green Plan 2030?
The Green Plan 2030 is a national roadmap to achieve net-zero emissions by 2050. It includes targets for increasing solar energy, planting 1 million more trees, reducing waste sent to the landfill, and ensuring that all new cars are 'cleaner-energy' models by 2030.
