Weather and climate related disasters cost the world $329 billion in 2021

Aon plc has published its ‘2021 Weather, Climate and Catastrophe Insight report’, which evaluates the increasing frequency and severity of disruptive natural disasters and how their resulting economic losses are protected globally.

The report reveals a total of $343 billion in economic losses in 2021, $329 billion of which resulted from weather and climate-related events, making last year the third costliest year on record after adjusting for inflation.

While losses were up from 2020, the number of notable disaster events slightly decreased, demonstrating the heightened costliness and severity of these events. Of the 2021 losses, only 38 percent were covered by insurance. Despite an increase in overall losses from 2020, the protection gap of economic losses not covered by insurance decreased from 63 percent to 62 percent in 2021.

"Clearly there is both a protection and innovation gap when it comes to climate risk," said Eric Andersen, president of Aon. "As catastrophic events increase in severity, the way that we assess and ultimately prepare for these risks cannot depend on solely historical data. We need to look to technology like artificial intelligence and predictive models that are constantly learning and evolving to map the volatility of a

Other key findings from the report include:

"Many global communities are exposed to increasingly volatile weather conditions that are in part enhanced by the growing effects of climate change. This includes record-setting episodes of extreme temperatures, rainfall and flooding, droughts and wildfires, rapidly intensifying tropical cyclones and late season severe convective storms," said Steve Bowen, meteorologist and head of Catastrophe Insight at Aon. "We can no longer build or plan to meet the climate of yesterday. With physical damage loss costs rising, this is also leading to lingering global disruptions to supply chains and various humanitarian and other asset-related services. The path forward for organizations and governments must include sustainability and mitigation efforts to navigate and minimize risk as new forms of disaster-related volatility emerge."
