The world is quickly running out of time to keep global warming under control, and this has big consequences for everyone—especially insurance companies. A recent report from the United Nations Environment Programme (UNEP) reveals that temperatures are now set to rise between 2.3 and 2.5 degrees Celsius this century. Although this is slightly better than earlier predictions, it’s still well above the 1.5-degree target set in the 2015 Paris Agreement.
The annual Emissions Gap Report, published on November 4, 2025, shows that the chances of keeping warming below 1.5 degrees are all but gone. Countries are still releasing record levels of greenhouse gases, and even with new promises to cut emissions, the report warns that emissions must drop by nearly half within this decade to prevent even worse damage. The UN Secretary-General António Guterres called the situation urgent, saying that a temporary rise above 1.5 degrees is likely to happen by the early 2030s, making the challenge to secure a livable future tougher all the time.
For insurance companies, this isn’t just about climate goals—it’s about real money. In the last five years, the U.S. has faced one disaster after another: wildfires, floods, hurricanes, and storms that have pushed claims to historic levels. In 2023 alone, losses from severe storms exceeded $50 billion, marking the highest year on record. Scientists warn that warmer oceans are causing hurricanes to strengthen faster than before. Some storms reach dangerous strength in less than a day, making it harder for people to prepare and causing more destruction.
This rise in claims has hit the insurance industry hard. Some insurers in high-risk areas like Florida and Louisiana have gone under, while others have had to stop covering certain risks. Reinsurance costs have jumped, meaning that primary insurers face bigger financial burdens. As the climate changes faster than risk models can keep up, insurers face a growing challenge to price risks accurately.
The UNEP report also points to a sluggish response from policymakers. Despite the upcoming COP30 climate summit, only about a third of the countries involved in the Paris Agreement updated their climate goals by September, covering just 63% of emissions worldwide. Even if all current pledges are met, global temperatures would still rise beyond 2 degrees Celsius. Current policies would push that even higher—close to 2.8 degrees—bringing serious risks and damages.
Inger Andersen, UNEP’s executive director, stressed that countries have missed their climate promises multiple times. Global emissions rose by 2.3% in 2024, mainly because coal and oil are still powering economic growth.
American insurers are already feeling the financial strain. Catastrophe-related losses have averaged $110 billion annually over the last three years, almost double the historic average. To cope, companies are tightening rules on what they cover, leaving many people and small businesses underinsured or uninsured. Some are looking to invest more in resilience measures like stronger buildings and better wildfire protections.
The report points out that while the situation looks bad, tools to fight climate change do exist. Clean energy sources, ways to cut methane emissions, and carbon capture technology are advancing faster than many expected. The missing piece is political will and coordinated financing.
For insurers, the growing climate risk is both a threat and an opportunity. They already use data to understand hazards like hurricanes and wildfires, and this expertise can help direct investments that reduce risk—like stricter building codes and better infrastructure. But the world is heading towards a 2.5-degree rise in temperature, and insurers face a tough choice: adapt quickly or face rising losses and risks that may become unmanageable.
The message is clear. Time is running out, and the decisions made now will shape how well the world—and the insurance industry—can handle the changing climate in the years to come.
