"It suggests that climate-related risks and pandemics such as Covid-19 have similarities. Both are massive global negative externalities and both are related to changes in our natural ecosystems. In addition to the extensive economic and financial damage they both produce, both directly affect human lives and thus could be classified as Green Swans. And, for both, there is a discrepancy between how scientists warn us about the quasi-certainty of their occurrence and how we fail to systematically consider their potentially huge costs and integrate them into risk frameworks and final prices."
