Impacts of a Changing Climate on Economic Damages and Insurance

Abstract - Weather and climate extremes cause huge economic damages and harm many lives each year (?35000/year). There is evidence that some types of weather and climate extremes, like heat waves and flooding, have already increased or intensified over the last few decades, and climate projections reveal a further intensification for many types of weather and climate extremes in many regions though the uncertainties still remain large. While there is evidence for increases in economic losses it is uncertain whether this is due to an increase in the number and intensity of extreme events or can be attributed to socio-economic changes. However, there is agreement that the increasingly complex and internationally distributed supply chains of global companies make them more vulnerable to extreme weather events. It is also thought that global warming will adversely affect the global food supply chain and especially developing countries. This report surveys how weather and climate extremes impact our economies and how we can mitigate their impacts using financial and insurance products.
