Hawaii's recent record-breaking floods have caused over $1 billion in damage, exposing the state's vulnerabilities to intensifying climate hazards. Experts say this is a pivotal moment to rethink policies, strengthen partnerships, and center equity in building climate resilience across the islands.

Why it matters

The floods highlight how climate change is amplifying existing weaknesses in Hawaii's infrastructure, economy, and communities. Low-income and marginalized groups face the greatest burdens, deepening inequality. Addressing this requires a fundamental shift towards climate-resilient development that reduces emissions while strengthening adaptation capacity.

The details

The Kona-low storms in March 2026 dumped extraordinary rainfall on Oahu and Maui, overwhelming drainage systems, forcing evacuations, and threatening critical infrastructure. Warmer oceans driven by global climate change are intensifying these storms and prolonging their impacts. The damage exceeds $1 billion, with families in places like Waialua and rural Maui facing flooded homes, power outages, and lost businesses.

What they’re saying

“Addressing this challenge is not solely the responsibility of government — it is a shared responsibility. While emergency response and federal support are essential, they are not sufficient. The path forward lies in embracing climate-resilient development, as defined by the Intergovernmental Panel on Climate Change: reducing emissions while strengthening our capacity to adapt, with benefits for equity, health and long-term sustainability.”

What’s next

Governments can offer subsidies to promote building retrofits, elevate structures, and support insurance access for vulnerable households. Land-use planning must evolve, limiting development in high-risk areas and integrating traditional ahupuaa systems with modern engineering to restore natural water flow and resilience.

The takeaway

Hawaii's experience underscores the need for a collective, systems-based approach to building climate resilience. By reexamining policies, strengthening partnerships, and centering equity, Hawaii can lead in demonstrating what climate-resilient development looks like in practice.
