Effects of climate change are manifesting in greater weather extremes, warns Swiss Re sigma
A deep winter freeze, hailstorms and wildfires contributed to insured natural catastrophe losses of $40 billion in the first half of 2021, according to Swiss Re Institute’s preliminary sigma estimates.
This is above the previous ten-year average of $33 billion and the second highest on record for a first half after 2011, when major earthquakes in Japan and New Zealand pushed the six-month total to $104 billion.
Man-made disasters triggered another estimated $2 billion of insured losses in the first half this year, less than usual and likely reflecting remaining COVID-19 restrictions.
Global economic losses from disaster events are estimated at $77 billion in the first half of 2021. This is below average for the past ten years ($108 billion). The economic loss figure is expected to rise as more losses are accounted for in the coming months.
The first half of the year is also not representative of the full-year figures, because the third quarter historically is the most loss-prone in terms of natural catastrophes. Close to 4 500 people lost their lives or went missing in disaster events in the first half.
Severe weather events push up natural catastrophe losses
Martin Bertogg, head of Cat Perils at Swiss Re, said: “The effects of climate change are manifesting in warmer temperatures, rising sea levels, more erratic rainfall patterns and greater weather extremes.”
”Taken together with rapid urban development and accumulation of wealth in disaster-prone areas, secondary perils, such as winter storms, hail, floods or wildfires, lead to ever higher catastrophe losses.”
”The experience so far in 2021 underscores the growing risks of these perils, exposing ever larger communities to extreme climate events. For example, winter storm Uri reached the loss magnitude that peak perils like hurricanes can wreak.”
”The insurance industry needs to upscale its risk assessment capabilities for these lesser monitored perils to maintain and expand its contribution to financial resilience.”
Going into the second half of the year, July saw severe flooding cause property destruction and loss of life in Europe and China. In China, severe flooding in Henan province resulted in estimated insured claims of CNY 11 billion ($1.7 billion), according to the China Banking and Insurance Regulatory Commission.
Jérôme Jean Haegeli, Swiss Re’s group chief economist, said: “Climate change is one of the biggest risks facing society and the global economy. The recent analysis from the UN’s Intergovernmental Panel on Climate Change confirms expectations of more extreme weather in the future and urgency to act to limit global warming.”
”Working with the public sector, the re/insurance industry plays a key role in helping to strengthen communities’ resilience by steering development away from high-risk areas, making adaptation investments, maintaining insurability of assets and narrowing protection gaps.”
