IB ESS SL 6.3 Climate Mitigation and Adaptation Question Bank

Practise IB ESS SL 6.3 by distinguishing mitigation from adaptation and evaluating emissions, reforestation and protective strategies.

Exam points

Classify mitigation as reducing climate causes and adaptation as managing consequences.
Evaluate emissions cuts, biofuels, carbon removal and reforestation through effectiveness and side effects.
Compare flood defence, water, crop, health and infrastructure adaptations for named climate risks.

Figure:Planned changes in energy supply in Cape Town, 2025-2050

Evaluate how the planned changes in the energy supply, shown in Figure: Planned changes in energy supply in Cape Town, 2025-2050, are likely to influence carbon emissions in Cape Town.

[Maximum number: 2]

Figure:CO₂ emissions for selected countries in 2007 and projected for 2030

There are concerns that increased carbon dioxide ( $\mathrm{CO}_{2}$ ) emissions are leading to changes in the global climate.

(a)

Identify one reduction strategy that the United States might use to achieve its projected change in $\mathrm{CO}_{2}$ emissions.

[ 1 ]

Identify one reduction strategy that the United States may use to achieve its projected change in CO2 emissions.
reduction of energy consumption/CO2 production through laws/taxes/education; use of alternatives to fossil fuels;
$\mathrm{CO}_{2}$ removal though CCS; afforestation / reducing rates of deforestation;

Marking guidance:

Accept any other reasonable suggestions, but they must be explicitly linked to reduction in C emissions ie not simply "improve public transport" or "recycling".

(b)

Identify one adaptation strategy that could be used to reduce the impacts of climate change.

[ 1 ]

[Maximum number: 7]

Compare and contrast the adaptation strategies to climate change for two societies.
