IB DP Geography Core: Global Climate -- Vulnerability and Resilience -- Revision Notes

The full syllabus guide confirms the SL/HL core (Geographic perspectives: global change) is identical in content and hours for every student, examined in Paper 2. These notes cover Global climate: vulnerability and resilience, alongside the Population distribution revision notes already on the site.

Why this core theme is universal (unlike the options)

Because the seven geographic-themes options are teacher-selected, revision material on an unstudied option is wasted. The core is different: every DP Geography student, regardless of school, studies Global climate as part of the shared 70-hour core, examined in Paper 2 for everyone. This makes it one of the highest-value topics to revise thoroughly, since it applies to every student without exception.

Core vocabulary

• Vulnerability – the degree to which a place, community or system is susceptible to harm from a climate hazard, shaped by exposure, sensitivity and adaptive capacity.
• Resilience – the capacity of a place or community to absorb, recover from, and adapt to climate-related disturbance.
• Adaptation – deliberate changes made in response to actual or expected climate impacts (for example, flood defences, drought-resistant crops).
• Mitigation – action taken to reduce the causes of climate change itself, distinct from adaptation’s focus on managing its effects.

Keep adaptation and mitigation clearly separate — a common error is using the two terms interchangeably, when the specification treats them as distinct types of response.

Worked example: comparing vulnerability across two places

A question asks why two places facing a similar climate hazard (e.g. flooding) might experience very different outcomes.

Exposure:          both places face a similar physical hazard
                    (rising flood risk)
Sensitivity:        Place A has more people living in low-lying,
                    poorly built housing; Place B has stronger
                    building codes and better drainage infrastructure
Adaptive capacity:  Place A has fewer economic resources and weaker
                    institutions to respond; Place B has greater
                    financial and institutional capacity to invest in
                    defences and recovery
Conclusion:         vulnerability is not just about the SIZE of the
                    hazard but the combination of exposure, sensitivity
                    and adaptive capacity -- two places facing an
                    identical hazard can have very different outcomes

Naming all three components of vulnerability (exposure, sensitivity, adaptive capacity) explicitly, rather than just describing that “one place is more vulnerable,” is what a strong Paper 2 answer does.

Named, specific case studies

As with every DP Geography theme, generic description scores lower than named, specific case studies with real dates, locations and figures. Build a small bank of specific vulnerability/resilience examples (a named flood event, drought, or heatwave with its human and policy response) that can be reused flexibly across different Paper 2 core questions.

Connecting to the geographic-themes options

Because the core is examined separately from the options, avoid the temptation to blend Global climate content into an option answer (or vice versa) without being explicit about which paper’s content you are using. That said, genuine thematic overlap exists — Extreme environments and Geophysical hazards both touch on climate-related vulnerability — so if your class studied either option, practise clearly distinguishing an option-specific point from a core Global climate point, since Paper 1 and Paper 2 are marked against different prescribed content even where the underlying geography is related.

HL extension connections

At HL, Global risks and resilience (part of the HL-only extension examined in Paper 3) builds directly on the core’s vulnerability and resilience vocabulary, applying it to interconnected global systems more broadly rather than climate specifically. HL students who have a secure grip on this core theme’s vocabulary will find the extension’s own vulnerability-and-resilience content considerably more accessible, since the underlying concepts transfer directly even though the scale and scope of the content differ.

Exam traps

• Confusing adaptation (managing a hazard’s effects) with mitigation (reducing the hazard’s causes).
• Describing vulnerability in general terms without naming its three components (exposure, sensitivity, adaptive capacity).
• Using vague, unnamed examples (“a developing country”) instead of a specific, named place and event.
• Assuming this theme is optional — it is compulsory core content examined in Paper 2 for every student.

Linking to the fieldwork report

Because the internally assessed fieldwork report can be based on any suitable syllabus topic, Global climate is a viable choice where local conditions allow a genuinely testable question — for example, investigating a community’s perceived vulnerability or adaptive responses to a local climate hazard. Where fieldwork engages with this core theme, use its specific vocabulary (exposure, sensitivity, adaptive capacity) to frame both the investigation’s question and its analysis, since this demonstrates direct application of taught core content rather than a generic geographic inquiry.

Self-test

1. Name the three components of vulnerability the specification identifies.
2. Distinguish adaptation from mitigation.
3. Why is Global Climate a higher-value revision priority than any single geographic-themes option?
4. What kind of evidence does a strong Paper 2 core answer use to support its argument?
5. Which paper examines the SL/HL core content?

Keeping this theme’s vocabulary and case-study bank genuinely separate from option-specific material, while still noting where the two legitimately connect, is the balance this core theme’s revision requires.

Answers: 1. Exposure, sensitivity and adaptive capacity. 2. Adaptation manages the effects of climate change already occurring (e.g. flood defences); mitigation acts to reduce the underlying causes of climate change itself. 3. Because it is compulsory core content for every DP Geography student, unlike the options, which are teacher-selected and therefore vary between classes. 4. Named, specific case studies with real dates, locations and figures, rather than generic description. 5. Paper 2.
