What Examiners Ask About Climate Change

• "Describe the evidence for climate change" — temperature records, ice cores, sea level rise, melting ice, changing seasons (3–4 marks)
• "Explain how burning fossil fuels causes climate change" — releases CO₂, enhanced greenhouse effect, more IR trapped, surface warms (3–4 marks)
• "Explain the difference between weather and climate" — short-term conditions vs long-term averages (2 marks)
• "Describe consequences of climate change" — sea level rise, extreme weather, ice melt, habitat loss (3–4 marks)
• "Evaluate mitigation strategies" — pros and cons of renewable energy, carbon capture, individual actions (4–6 marks)
• "State uncertainties in climate science" — complex feedback mechanisms, regional predictions, tipping points (2 marks)

Edexcel 1CH0: Examined in Paper 2 (1CH0/2). Edexcel requires evaluation of evidence for human-caused climate change and discussion of measures to reduce carbon emissions — 'Suggest' questions are common here. In Edexcel-style questions, the command word "Suggest" appears frequently — use your chemistry knowledge to apply to an unfamiliar context.
