Climate Risk Assessment: Key Takeaways
Essential insights from your climate risk journey
Your Progress
Section 5 of 5The Climate Risk Assessment Framework
Hazard
Climate threats—acute events (floods, storms) and chronic stresses (droughts, sea-level rise). Know your exposures.
Vulnerability
Who and what is at risk? Physical, social, economic, environmental, and institutional dimensions shape susceptibility.
Risk
Risk = Hazard × Exposure × Vulnerability. Quantify to prioritize actions and track progress over time.
Climate Risk = Hazard × Exposure × Vulnerability
Reducing any component reduces overall risk
Ten Critical Insights
Climate risk is multiplicative, not additive
Reducing hazard OR vulnerability OR exposure reduces overall risk. Small changes compound.
Vulnerability is differential and dynamic
Same hazard, different impacts. Elderly, low-income, and marginalized communities face disproportionate risks.
Compound and cascading risks amplify impacts
Drought + heat wave + wildfire. Infrastructure failure cascades across systems. Think systemically.
Near-term risks are locked in; far-term risks are uncertain
2030s warming is largely determined. 2050+ depends on emissions pathway. Plan for both.
Adaptation is cost-effective
Every $1 invested in resilience saves $4-10 in avoided damages. The question isn't if, but how.
No-regret actions reduce risk across scenarios
Robust decisions work under uncertainty: ecosystem restoration, early warning systems, building codes.
Community knowledge complements climate models
Local and indigenous knowledge reveals lived experience, historical patterns, and context models miss.
Risk assessment is iterative, not one-and-done
Climate science evolves, conditions change, new vulnerabilities emerge. Update regularly.
Metrics matter for accountability
What gets measured gets managed. Track progress with clear indicators and transparent reporting.
Equity must be central to risk assessment
Those least responsible for climate change often face greatest risks. Justice demands prioritizing vulnerable populations.
Your Next Steps
1. Define scope and stakeholders
Geographic boundaries, asset types, time horizons, who needs to be at the table?
2. Gather climate projections and historical data
Access downscaled models, local observational records, and expert assessments for your region.
3. Conduct participatory vulnerability assessment
Engage communities, map differential vulnerabilities, identify adaptation capacity and barriers.
4. Quantify and prioritize risks
Use scenario analysis, cost-benefit frameworks, and risk matrices to identify highest-priority actions.
5. Develop and implement adaptation plan
Design interventions, secure financing, establish monitoring systems, and iterate based on outcomes.
