The devastating impact of extreme weather is a growing concern, as it leaves thousands of homes across the globe uninsurable. This issue should be a wake-up call for all of us, regardless of where we live.
Insurance is not just about protecting our homes; it's the backbone of modern economies. Without insurance, the financial system could crumble, and the consequences would be catastrophic. As Felicity Alvey, an expert from the University of Cambridge, puts it, "We're witnessing more frequent and severe extreme weather events, and this is affecting insurance claims and pricing worldwide."
The climate crisis is already taking its toll. In the US, especially in the western and southeastern regions, insurance premiums are skyrocketing due to increased climate risks. Commercial insurers are withdrawing, leaving state-backed insurers to bear the burden. For instance, California's Fair Plan has seen its exposure soar to a staggering $724 billion since 2022.
Europe is also facing its fair share of challenges. Spain and Portugal, battered by extraordinary rains, have had to provide billions of euros in aid. In the UK, the western regions have experienced an unusually wet start to the year, with one Cornish village enduring 50 consecutive days of rain. This has led to warnings of "mortgage prisoners" - people unable to sell their homes due to flood risks, which could result in rising defaults for banks.
The climate crisis is far from over, and its impact on insurance is a cause for concern. Scientists predict that by 2035, the number of people exposed to flood risks in China's Pearl River delta will increase by 25%, even with carbon emission cuts. This region, home to 86 million people, is at serious risk.
An insurance crisis has far-reaching implications. As Alvey explains, "Insurance protects what people have worked hard for. It provides financial stability during shocks, allowing people to continue their lives."
The top insurer, Allianz SE, has warned that the climate crisis could destroy capitalism itself. Günther Thallinger, a board member, stated last year that "Entire regions are becoming uninsurable." This concern is shared by the International Association of Insurance Supervisors, who warn of systemic risk and financial instability if assets linked to bank lending become less insurable.
The impact of the climate crisis is not just financial. Flood victims often suffer long-lasting trauma, with some experiencing panic attacks whenever it rains. It's a profound and lasting psychological impact.
So, what can be done? The UK has pioneered a solution called Flood Re, a government-industry partnership. It uses a small levy on everyone's insurance premiums to keep coverage affordable for those in flood-risk areas. Without Flood Re, premiums would be in the thousands of pounds, with excesses in the tens of thousands. Since its launch in 2016, over 600,000 homes have benefited.
However, there are concerns about the long-term sustainability of this scheme. Flood Re's boss warned last July that the UK's flood resilience has deteriorated, leaving hundreds of thousands of homes at risk of becoming uninsurable by 2039. Tracey Garrett of the National Flood Forum says, "We're storing up a massive problem for people in the future."
The next five to ten years are critical, according to Kelly Ostler-Coyle, Flood Re's director of corporate affairs. "We're working hard to help the UK live better with water, building resilience and ensuring quicker and less disruptive recovery after floods." This includes promoting protection measures like self-closing air bricks and raising electrics on walls.
It's important to remember that many people worldwide have never been able to afford insurance, even as the climate crisis increases the need for it. The Insurance Development Forum's programs have helped provide financial protection to 4 million people in 2025, but there's still a long way to go.
Insurers, as experts in risk, have been issuing warnings about the climate crisis making insurance unaffordable for ordinary people. When these warnings start to become a reality, it's a stark reminder that we must act now. The time to address this issue is now, before it's too late.
