Explain how people respond to climate change through mitigation (reducing emissions) and adaptation (coping with the effects)

What this dot point is asking

This outcome asks you to explain how people respond to climate change, both by reducing its causes and by coping with its effects. You must understand the difference between mitigation and adaptation and give examples of each. The central idea is that tackling climate change needs two approaches at once: slowing the warming by cutting emissions, and protecting people from the impacts that are already happening.

The answer

The two responses: mitigation and adaptation

There are two main ways to respond:

• Mitigation means reducing the causes of climate change, mainly by cutting greenhouse gas emissions so the warming is slowed.
• Adaptation means changing how we live to cope with the effects that are already happening or cannot be avoided.

Both are needed: mitigation tackles the problem at its source, while adaptation protects people in the meantime.

Mitigation: reducing emissions

Ways to cut greenhouse gases include:

• Renewable energy: switching from coal, oil and gas to solar, wind, hydro and other clean sources, which release little or no carbon dioxide.
• Energy efficiency: using less energy through better insulation, efficient appliances and public transport, so fewer emissions are produced.
• Protecting and planting forests: trees absorb carbon dioxide, so reducing deforestation and planting more trees helps.
• Reducing car use: walking, cycling and public transport cut emissions from vehicles.

Adaptation: coping with the effects

Ways to cope with impacts include:

• Coastal defences: building sea walls and raising land to protect low-lying coasts from rising seas and flooding.
• Better drainage: larger drains and canals to handle heavier rainfall and reduce flash floods.
• Drought-resistant crops and improved water storage to keep food and water supplies secure.
• Warning systems and planning to protect people from extreme weather.

Action at every level

Responses happen at different scales: individuals save energy and travel greener; governments set laws, invest in renewables and build defences; and countries work together in international agreements to cut emissions worldwide. Climate change is a global problem, so cooperation matters.

Examples in context

Example 1. Singapore's coastal protection and solar push. Singapore adapts by studying sea-level rise and building coastal defences and large drainage canals to handle flooding, and mitigates by deploying solar panels on rooftops and reservoirs and improving energy efficiency. It is a clear example of a country using both adaptation and mitigation together.

Example 2. International agreements to cut emissions. Countries have signed global agreements that set targets to reduce greenhouse gas emissions, because climate change crosses borders and no single country can solve it alone. Such cooperation is a key part of mitigation at the international scale, showing why global action matters.

Try this

Q1. Define mitigation and give one example. [2 marks]

• Cue. Mitigation means reducing the causes of climate change by cutting emissions; for example switching to renewable energy.

Q2. State two ways a low-lying area could adapt to rising sea levels. [2 marks]

• Cue. Building sea walls and improving drainage (also raising land or using flood warning systems).

Q3. Explain why international cooperation is important for tackling climate change. [2 marks]

• Cue. Climate change is a global problem caused by emissions everywhere, so countries must work together to cut emissions worldwide; no single country can solve it alone.
