Introduction: Climate Change and the Insurance Industry

The insurance industry is experiencing unprecedented disruption due to the escalating impacts of climate change. As extreme weather events become more frequent and severe, insurers are re-evaluating traditional risk models, coverage options, and investment strategies. This shift presents both challenges and opportunities for policyholders, industry professionals, and communities seeking protection and resilience in a volatile environment.

Understanding the Impact: Rising Costs and Increased Risk

Climate change has driven a significant increase in the frequency and intensity of disasters such as hurricanes, wildfires, floods, and severe storms. In just the first half of 2025, global insured losses from natural catastrophes reached $100 billion-40% higher than the previous year and more than double the 21st-century average. These losses, concentrated in regions like Los Angeles and across the U.S., highlight the growing financial exposure of insurers and policyholders alike [2] .

Despite the rising costs, the share of uninsured global losses has dropped to a record low of 38%, indicating increased insurance uptake in some markets. However, a significant portion of assets remains unprotected, especially in low- and middle-income countries, widening the global protection gap [1] . In the U.S., affordability concerns have led an estimated 8% of homeowners to forgo insurance altogether, leaving $1.6 trillion in assets at risk [1] .

How Insurers Are Adapting: New Strategies and Tools

Insurers are responding to climate risk by updating their catastrophe models, which traditionally relied on historical data and did not account for the increased frequency and severity of extreme events. Incorporating advanced analytics, artificial intelligence, and updated climate projections enables insurers to better estimate and price risk. However, these models must continually evolve to keep pace with the fast-changing climate landscape [3] .

Leading insurers are adopting comprehensive frameworks to evaluate both their underwriting and investment portfolios. This includes setting science-based targets, measuring greenhouse gas emissions across their operations, and developing actionable climate transition plans. Companies are also increasing collaboration on industry-wide standards and methodologies to ensure consistency and transparency in climate-related disclosures [1] [4] .

Accessing Insurance Solutions in a Changing Climate

For individuals and businesses seeking coverage, navigating the new insurance landscape requires proactive steps:

Assess Your Risk: Review your property’s vulnerability to climate-related hazards such as floods, wildfires, or hurricanes. Many insurers now provide online tools and risk maps to help policyholders understand their exposure.
Update Your Coverage: Contact your insurance provider to discuss policy options that address current and emerging risks. Ask about available endorsements, riders, or new products designed for climate resilience.
Consider Community-Based Solutions: In areas where traditional insurance is unavailable or unaffordable, explore alternative models such as parametric insurance, public-private partnerships, or community risk pools. These are often coordinated through local governments or specialized risk management organizations.
Leverage Industry Resources: The National Association of Insurance Commissioners (NAIC) encourages consumers to use their state insurance departments for guidance on coverage requirements and consumer protections. You can locate your state’s insurance department by searching “[Your State] Department of Insurance.”

Be aware that insurance availability and requirements vary by state and region. If you experience difficulty securing coverage, you may be eligible for state-backed or residual market plans. To explore these options, contact your state insurance regulator or visit their official website for information on Fair Access to Insurance Requirements (FAIR) plans or similar programs.

Industry Regulation and Climate Risk Disclosure

To address the evolving threat, regulators are increasing demands for climate risk disclosure and resilience planning. In the U.S., insurers with $100 million or more in premiums are required to complete climate risk disclosure surveys based on the Task Force on Climate-related Financial Disclosures (TCFD) framework. However, this requirement is not universal-currently, only 29 states and territories, representing about 85% of the market, participate [4] . The TCFD approach focuses on four pillars: governance, strategy, risk management, and metrics and targets.

Globally, organizations like the International Association of Insurance Supervisors (IAIS) monitor the industry’s climate exposures and promote best practices for financial stability. Their annual Global Insurance Market Report (GIMAR) provides quantitative data and guidance on the sector’s adaptation strategies [5] . These efforts aim to create a more resilient and transparent insurance ecosystem that can better protect policyholders and the broader economy.

Practical Steps for Policyholders Facing Climate Risk

If you are concerned about your coverage due to climate-related risks, consider the following actions:

Review your policy annually: Climate risks can change rapidly. Ensure your policy limits and covered perils reflect current exposures.
Document your property and assets: Maintain up-to-date records and photographs to simplify claims in the event of a loss.
Invest in risk mitigation: Insurers may offer discounts for resilience measures such as installing storm shutters, elevating structures, or creating defensible space around properties in wildfire zones.
Consult your agent or broker: Regularly discuss your risk profile and available options. If your insurer is non-renewing your policy, ask about alternatives, including surplus lines or specialty carriers.
Engage with local officials: Community-wide risk reduction measures-such as improved building codes or flood control infrastructure-can lower insurance costs for everyone.

For those unable to secure private insurance, you may find assistance through state-sponsored programs. Search for your state’s FAIR Plan or residual market program and contact the program administrator directly for application steps and eligibility requirements. Some states also provide disaster preparedness grants or technical support for mitigation projects-visit your state’s emergency management agency or insurance regulator for details.

The Road Ahead: Innovation, Collaboration, and Resilience

The insurance industry is poised to play a pivotal role in building societal resilience to climate change. By moving beyond traditional risk transfer to proactive risk management, insurers can help communities adapt to emerging threats and close the protection gap. This includes investing in new technologies, collaborating with governments and policyholders, and developing flexible products that reflect the realities of a changing climate [3] .

Staying informed and engaged is crucial. Regularly review guidance from your insurer, state insurance department, and reputable organizations such as the NAIC and IAIS. Consider subscribing to industry newsletters, attending community preparedness workshops, or consulting independent experts to stay ahead of evolving risks and coverage options.
