🎯 Common Question Types:
- Describe evidence for climate change (3–4 marks)
- Explain link between CO₂ and global warming (3 marks)
- Distinguish weather from climate (2 marks)
- Describe consequences (2–4 marks)
- Evaluate mitigation strategies (4–6 marks extended writing)
📝 Key Command Words:
- Describe: State what the evidence shows
- Explain: Give reasons with CO₂ and greenhouse effect
- Evaluate: Weigh up evidence AND uncertainties
- Assess: Judge effectiveness of strategies with reasons
⚠️ Common Mistakes to Avoid:
- Saying climate change = only temperature rise — it includes sea level, ice, rainfall, extreme weather
- Using a single cold weather event to argue against warming — that's weather, not climate
- Forgetting to link consequences back to the enhanced greenhouse effect mechanism
- In evaluation questions: must give BOTH advantages and disadvantages of each strategy
- Mixing up correlation and causation — we understand the mechanism, not just a correlation
