Tropical Storm Lala heads toward Hawaii; life-threatening floods possible » Yale Climate Connections

Nature & Climate Perspective

**Severe tropical storm systems and potential flooding severely exacerbate permanence risks for coastal and forest ecosystems across vulnerable island and coastal habitats. **

• Acute precipitation and storm surges threaten coastal Blue Carbon ecosystems through physical degradation and increased sediment runoff.
• Extreme flooding destabilizes localized LULUCF carbon sinks, creating heightened carbon reversal risks for regional offset projects.
• Repeated disturbance events weaken ecological resilience, threatening long-term biodiversity stability and natural carbon sequestration capacity.

Market & Policy Outlook

**Accelerating physical climate risks are forcing market re-evaluations of carbon project buffer pools and insurance mechanisms to align with ICVCM permanence requirements. **

• Escalating climate hazards prompt stricter regulatory scrutiny under ICVCM Core Carbon Principle 5 (Permanence) and Article 6.4 baseline methodologies.
• Extreme weather volatility drives up risk premiums and insurance costs for nature-based assets, threatening financial liquidity in regional carbon markets.
• Corporations addressing physical risks in their Scope 3 supply chains must integrate robust climate adaptation policies into their SBTi science-based targets.
