Exam Connection — OCR B Geography

🎯 Exam Connection — OCR B Geography

Paper: Paper 1 — Our Natural World (Global Hazards, Topic 1 — including climate change as a hazard context)

Exam frequency: Very high — climate change appears explicitly in almost every paper as a context for other hazard questions, as well as in dedicated question sections. It is also a cross-paper theme: understanding climate change is essential for questions about coasts, rivers, ecosystems and development.

Typical OCR Question Types for This Topic:

• "State one piece of evidence that global temperatures are rising." [1–2 marks] — Give a specific statistic. Example: "The global average temperature in 2023 was 1.45°C above the pre-industrial baseline, making it the hottest year ever recorded." Or: "Ice cores show CO₂ has risen from 280 ppm to 421 ppm — the highest level in at least 3 million years."
• "Explain one natural and one human cause of climate change." [4 marks] — Two explained points. Natural: Milankovitch cycles change how much solar radiation reaches Earth over 20,000–100,000-year cycles — but they operate far too slowly to explain modern warming. Human: burning fossil fuels releases 38 billion tonnes of CO₂ per year, increasing atmospheric concentrations and enhancing the greenhouse effect.
• "Explain how the enhanced greenhouse effect leads to global warming." [4 marks] — You need the mechanism: solar radiation passes through → Earth emits infrared → greenhouse gases absorb and re-emit infrared → more heat trapped → energy imbalance → warming. Link to increased concentrations from human activities.
• "Assess the effectiveness of strategies to manage climate change." [6–8 marks] — This requires named examples of both mitigation and adaptation, with a supported judgement. Compare at least two strategies (e.g. Paris Agreement vs Netherlands Room for the River). Judge which approach is more effective/realistic.
• "How far does development level affect the ability of countries to adapt to climate change?" [6–8 marks] — Compare HIC (Netherlands: €2.3 billion programme) with LIC (Bangladesh: floating gardens, flood-tolerant rice). Make a supported judgement — yes, wealth matters enormously, but LIC approaches can also be highly effective and appropriate.

What Gets You to Level 3 (Top Marks):

• Specific statistics — "421 ppm", "38 billion tonnes", "3.7 mm/year", "28 times more potent" — not vague descriptions
• Named examples with detail — "Germany's Energiewende" or "the Sleipner Project, Norway (since 1996)" — not "some countries are using renewables"
• The mechanism, not just the fact — "because CO₂ absorbs and re-emits infrared radiation, trapping heat" — not just "CO₂ causes warming"
• A supported judgement for assess/evaluate questions — "Overall, adaptation strategies are more immediately achievable because... although mitigation is essential in the long term because..."
• Linking physical cause to human consequence — "sea level rise of 3.7 mm/year threatens 17 million people in Bangladesh living below 1 m elevation"

OCR Command Words for Climate Change:

• State / Describe: Give the key information — ideally with a statistic. No explanation needed.
• Explain: Give a reason WITH a mechanism — "because" is essential. Link cause to effect through a chain of reasoning.
• Assess / Evaluate: Make a supported judgement — consider both sides, give evidence, reach a conclusion. "Overall..." is your final sentence.
• Compare: Explicitly state similarities AND differences using "whereas", "however", "in contrast". Do not write two separate descriptions — link them.
