Reducing greenhouse gas emissions not only lowers expected damages from climate change but also reduces the risk of catastrophic impacts. However, estimates of the social cost of carbon, which measures the marginal value of carbon dioxide abatement, often do not capture this risk reduction...

There is a low but uncertain probability that climate change could trigger "mega-catastrophes," severe and at least partly irreversible adverse effects across broad regions. This paper first discusses the state of current knowledge and the defining characteristics of potential climate change...

Scholars and policymakers have argued that insurance can shape behavior in ways that mitigate climate risks, such as by providing financial incentives to property owners to safeguard their property from increasingly intense hurricanes or from the risk of sea-level rise. But natural ecosystems...
