Impacts of Climate Change Study Notes — Cambridge IGCSE Geography 0460 (2024-2026 syllabus)

Sea-level rise, extreme weather, agricultural shifts, ecosystem damage. Why developing countries bear disproportionate burden. Bangladesh case study.

What you’ll learn

Mapped to the Cambridge IGCSE 0460 syllabus (2024-2026).

5.2.1 — Identify climate-change impacts.
5.2.2 — Explain climate inequality.
5.2.3 — Use named case study (Bangladesh).

Impacts of climate change

Sea level, weather, agriculture, ecosystems.

Sea-level rise. ~20 cm to date; accelerating. Threatens low-lying coasts (Bangladesh, Maldives, Pacific islands, Florida). Forced migration.

Extreme weather. More intense hurricanes, heatwaves, droughts, floods. 'Once-in-a-century' events now common.

Agricultural shifts. Warming shifts growing zones. Some areas gain (cool regions), but tropical areas suffer reduced yields. Food security threatened.

Ecosystem damage. Coral reef bleaching. Species range shifts. Extinctions. Ocean acidification.

Health. Heat deaths; disease range expansion (malaria, dengue); food insecurity.

Cambridge tip. Mark scheme rewards FOUR-plus impacts named with examples.

Sea level, extreme weather, agriculture, ecosystems.
Health and economic impacts too.
Compounding effects.

Climate inequality

Those who emit least suffer most.

Geographic exposure. Many developing countries in tropical or low-lying areas. Bangladesh: huge population on flat delta. Pacific islands: meters above sea level.

Agricultural dependence. Higher % of population in farming/fishing. Climate shifts hit livelihoods hard.

Limited adaptation resources. Fewer dykes, emergency infrastructure, insurance. Adaptation depends on slow international aid.

Climate INJUSTICE. Rich countries emit most; poor countries suffer most. Major equity issue at international climate negotiations.

Cambridge tip. Top-band answers include JUSTICE dimension.

Exposure + dependence + limited resources.
Climate justice — emitters ≠ sufferers.
International equity issue.

Bangladesh case study

Climate front line.

Bangladesh. Low-lying delta. 170 million people. Agriculture-dependent.

Flooding. 60%+ of land floods annually; climate change INTENSIFIES. Cyclones (Sidr 2007 killed 3,400+; Aila 2009 displaced millions). Sea-level rise threatens 17% of land by 2050.

Agriculture. Salt-water intrusion damages rice farms. Heatwaves reduce yields. Forces climate migration to Dhaka and to India.

Mitigations. Mangrove restoration; cyclone shelters; raised platforms; flood-resistant rice strains.

Cambridge tip. Memorise Bangladesh specifics.

170M people, low-lying delta.
Floods + cyclones + sea-level rise + salinisation.
Mangrove restoration + cyclone shelters.

Step-by-step worked examples — Impacts of Climate Change at Local, Regional and Global Scales

Step-by-step solutions to past-paper-style questions on impacts of climate change at local, regional and global scales, written exactly the way a tutor would explain them at the board.

1Impacts of climate change (8 marks)
Extended• Adapted from 0460/12 Oct/Nov 2024• impacts
Question
Describe FOUR impacts of climate change. (8 marks)
Step-by-step solution
1. Step 1
  Sea-level rise (2 marks). ~20cm rise to date; accelerating. Threatens low-lying coasts (Bangladesh, Maldives, Pacific islands, Florida). Forced migration.
2. Step 2
  Extreme weather (2 marks). More intense hurricanes, heatwaves, droughts, floods. 'Once-in-a-century' events now common. Cost lives and infrastructure.
3. Step 3
  Agricultural shifts (2 marks). Warming shifts growing zones. Some areas gain (cooler regions), but tropical areas suffer reduced yields. Food security threatened.
4. Step 4
  Ecosystem damage (2 marks). Coral reef bleaching, species range shifts, extinctions, ocean acidification. Massive biodiversity loss.
Answer
Sea-level rise, extreme weather, agricultural shifts, ecosystems. Other: health (heat, disease), economic, conflict.
2Climate inequality (6 marks)
Extended• inequality
Question
Explain why developing countries are MORE vulnerable to climate change. (6 marks)
Step-by-step solution
1. Step 1
  Geographic exposure (2 marks). Many developing countries are in tropical regions or low-lying areas. Bangladesh: huge population on flat delta. Pacific islands: meters above sea level.
2. Step 2
  Agricultural dependence (2 marks). Higher proportion of population in farming/fishing. Climate shifts hit livelihoods hard.
3. Step 3
  Limited resources for adaptation (2 marks). Fewer dykes, less emergency infrastructure, less insurance, less ability to relocate. Adaptation projects depend on slow international aid.
Answer
Exposure + dependence + limited resources. Climate change is climate INJUSTICE — those who emit least suffer most.
Examiner tip
Top-band answers include the JUSTICE dimension — emitters are mostly rich countries; suffering mostly poor countries.
3Named example impact (6 marks)
Extended• case-study
Question
Using a NAMED example, describe climate-change impact on a country. (6 marks)
Step-by-step solution
1. Step 1
  Named example: Bangladesh (2 marks). Low-lying delta, 170 million people, agriculture-dependent.
2. Step 2
  Flooding (2 marks). 60%+ of land floods annually; climate change INTENSIFIES. Cyclones (Sidr 2007 killed 3,400+; Aila 2009 displaced millions). Sea-level rise threatens 17% of land by 2050.
3. Step 3
  Agriculture (2 marks). Salt-water intrusion damages rice farms. Heatwaves reduce yields. Forcing climate migration to Dhaka and to India.
Answer
Bangladesh: low-lying, dense population, agriculture-dependent. Floods + cyclones + sea-level rise + salinisation = climate-front-line.

Key Definitions and Keywords — Impacts of Climate Change at Local, Regional and Global Scales

Definitions to memorise and the exact keywords mark schemes credit for impacts of climate change at local, regional and global scales answers — sharpened from recent examiner reports for the 2026 0460 sitting.

Climate vulnerability
Examiner keyword
How exposed a population or ecosystem is to climate change impacts. Depends on geographic, economic, and social factors.
Climate refugee
Examiner keyword
Person displaced by climate-change-related impacts (sea-level rise, drought, disaster). Hundreds of millions projected by 2050.
Climate justice
Examiner keyword
Principle that those most affected by climate change are often those least responsible for causing it. Major equity issue.
Coral bleaching
Loss of symbiotic algae when corals are stressed by warming. Coral turns white; dies if stress persists.
