Managing climate change requires two complementary, simultaneous strategies: mitigation (reducing the cause) and adaptation (responding to unavoidable effects). Effective climate management also involves navigating complex stakeholder tensions and applying sustainability principles.
| Strategy | Definition | Time horizon | Example |
|---|---|---|---|
| Mitigation | Reducing greenhouse gas emissions or enhancing carbon sinks to slow climate change | Long-term (decades–centuries) | Solar and wind energy replacing coal |
| Adaptation | Adjusting human and ecological systems to respond to current and future climate change | Near-term (immediate to decades) | Building sea walls; shifting crops |
Both strategies are necessary: mitigation reduces future harm; adaptation manages unavoidable harm already locked in by existing emissions.
Even if all emissions stopped today, temperatures would continue to rise for decades due to:
- Thermal lag: Oceans absorb heat slowly; warming continues as they equilibrate
- Committed warming: CO$_2$ already in the atmosphere will continue trapping heat
Therefore, adaptation is essential for near-term impacts already in train. Without mitigation, however, adaptation alone becomes increasingly insufficient as warming intensifies.
Climate management operates at multiple scales:
| Scale | Example Actions |
|---|---|
| Individual | Reduce energy consumption, dietary choices, transport |
| Community/local | Green infrastructure; urban heat mitigation; local energy networks |
| National | Emissions reduction targets; renewable energy mandates; carbon pricing |
| International | Paris Agreement; technology transfer; climate finance |
| Principle | Application to Climate Management |
|---|---|
| Intergenerational equity | Emissions reduction protects future generations from the worst impacts |
| Precautionary principle | Act on best available science even though projections have uncertainty |
| Conservation of ecological integrity | Protect biodiversity from climate-driven range shifts and bleaching |
| User pays principle | Carbon pricing makes emitters bear the cost of emissions |
| Intragenerational equity | Climate impacts fall disproportionately on least-responsible, most vulnerable nations |
Managing climate change involves genuine tensions:
- Economic development vs. emissions reduction: Nations at different stages of development have different capacity and historical responsibility
- Short-term costs vs. long-term benefits: Mitigation requires investment now for benefits decades hence
- Stakeholder conflicts: Energy companies, farming sectors, transport industries, environmental groups and vulnerable communities have different interests
- National vs. global: No single country’s actions are sufficient; collective action problems arise
STUDY HINT: In VCAA exams, distinguish clearly between mitigation and adaptation. A common error is to describe adaptation strategies as mitigation (e.g. ‘building a sea wall reduces climate change’ — it does not; it adapts to sea level rise). Mitigation always involves reducing emissions or increasing carbon sinks.
