Year 8 Geography: Climate Change Threats and Human Responses

Introduction to Climate Change

Hello, Year 8! Today, we are going to explore climate change. This is a big topic, but we can break it down into simpler parts. Climate change refers to long-term changes in temperature and weather patterns.

What Causes Climate Change?

1. Greenhouse Gases: These gases, like carbon dioxide (CO₂) and methane (CH₄), trap heat from the sun in the Earth’s atmosphere. This is similar to how a greenhouse works, keeping plants warm inside.
2. Human Activities: Many activities we do contribute to greenhouse gases. For example:
   • Burning fossil fuels (like coal and oil) for energy.
   • Deforestation, which means cutting down trees that absorb CO₂.
   • Agriculture, especially livestock farming, which produces methane.

Threats of Climate Change

Climate change poses several threats to our planet and our lives. Here are some key threats:

1. Rising Temperatures

• What Happens: Average global temperatures are increasing.
• Impact: This can lead to heatwaves, which can cause health problems and affect crops.

2. Melting Ice Caps and Glaciers

• What Happens: Ice in the Arctic and Antarctic is melting.
• Impact: This raises sea levels, which can flood coastal areas.

3. Extreme Weather Events

• What Happens: More frequent and severe storms, floods, and droughts.
• Impact: This can destroy homes, disrupt food supplies, and lead to loss of life.

4. Ocean Acidification

• What Happens: Increased CO₂ in the atmosphere is absorbed by oceans.
• Impact: This harms marine life, especially coral reefs and shellfish.

Human Responses to Climate Change

Humans are not just sitting back and letting climate change happen. We are taking steps to respond to it. Here are some examples:

1. Reducing Carbon Footprint

• What Can We Do: Use public transport, walk, or cycle instead of driving.
• Why It Matters: This reduces the amount of CO₂ we put into the atmosphere.

2. Renewable Energy Sources

• Examples: Solar power, wind power, and hydroelectric power.
• Why It Matters: These sources do not produce greenhouse gases.

3. Reforestation

• What It Is: Planting trees to replace those that have been cut down.
• Why It Matters: Trees absorb CO₂ and help cool the planet.

4. Climate Education

• What It Is: Teaching people about climate change and its effects.
• Why It Matters: The more we know, the better we can protect our planet.

Key Rules for Understanding Climate Change

1. Remember the Greenhouse Effect: It’s essential to understand how greenhouse gases work.
2. Identify the Threats: Be aware of how climate change affects different aspects of life and the environment.
3. Recognise Our Role: Everyone can make a difference, no matter how small.

Tips and Tricks to Understand Climate Change

• Visual Aids: Use diagrams and charts to see how temperature changes over time.
• Group Discussions: Talk with friends about climate change to share ideas and solutions.
• Stay Updated: Read articles or watch documentaries on climate change to learn more.
