Natural catastrophes: How can we be more resilient?

As Earth's warming trend continues, climate change and urban sprawl are putting more of us in harm's way. It's time we turn the tide.

The risk we face from natural catastrophes (Nat Cat) is on the rise. That's because we live, build and work in locations most at risk from floods, storms, wildfires and extreme weather events. In cities or towns along the coast, on floodplains or near wildland – climate change is fuelling the risk in these areas, making weather-related disasters more likely and more severe.

In its latest sigma report, Swiss Re Institute puts the figure of natural catastrophe losses at USD 137 billion in 2019 alone. Most of them were caused by smaller recurring events linked to extreme weather – a sign that climate change is increasingly visible in our loss numbers. With almost two-thirds of the damage uninsured, millions of people and businesses continue to be exposed to a large protection gap.

This shows the stakes are high and rising.

What do Australian bushfires, UK floods and Japanese typhoons have in common?

These events are all part of the same global story. As urban populations grow and our climate continues to change, weather-related disasters are increasingly hitting our communities. Insurance protects residents and businesses against financial hardship by helping them back on their feet after a disaster. But to keep these risks insurable in the future, we need to adapt to climate change by taking appropriate measures now.
