“The Significance of Tropical Cyclones: How They Amplify the Social Cost of Carbon”

Recent Research Reveals a Substantial Increase in the Social Cost of Carbon Due to Tropical Cyclones

A new study has shed light on the profound impact of tropical cyclones on the global Social Cost of Carbon, uncovering an increase of more than 20%. This surge in cost estimation is primarily attributed to projected damage escalation in major economies as a consequence of ongoing global warming. The research underscores a critical oversight in current climate change cost assessments, as it fails to account for the enduring economic repercussions of extreme events like tropical cyclones.

While extreme events such as tropical cyclones exhibit immediate effects, their far-reaching consequences for societies have been highlighted in a recent publication in the esteemed journal “Nature Communications.” The study presents a striking revelation: When factoring in the long-term consequences of these storms, the global Social Cost of Carbon surges by over 20%, compared to the prevailing estimates employed for policy evaluations. This substantial increase is primarily driven by the anticipated rise in tropical cyclone-related damages affecting major economies such as India, the USA, China, Taiwan, and Japan within the context of global warming.

The lead author of the study, Hazem Krichene, a scientist affiliated with the Potsdam Institute for Climate Impact Research (PIK), emphasizes the profound impact of intense tropical cyclones on a country’s economic development. The analysis indicates that such cyclones possess the capability to impede a nation’s economic progress for more than a decade. Furthermore, with the ongoing effects of global warming, the likelihood of successive cyclones hindered economies from fully recovering becomes increasingly probable. Consequently, the long-term consequences, including reductions in economic growth induced by tropical cyclones, could potentially exert more substantial harm on economic development than the immediate economic damage incurred by these storms.

The concept of the “Social Cost of Carbon” quantifies, in monetary terms, the future costs imposed on societies due to the emission of one additional ton of carbon dioxide into the atmosphere. This pivotal metric plays a central role in policy evaluations by enabling a comparison between the costs of climate change and those of climate mitigation measures. However, as co-author Franziska Piontek from PIK highlights, the current estimates of the Social Cost of Carbon fail to incorporate the long-term effects of extreme events. Consequently, these estimates only provide a partial representation of the actual costs, suggesting that the real expenses associated with climate change are likely higher than presently estimated, while the benefits of climate mitigation measures may be underestimated.

The nexus between a hotter climate and the intensification of tropical cyclones results in augmented costs. To conduct their study, researchers analyzed the economic damages inflicted by these storms across 41 countries prone to tropical cyclones between 1981 and 2015. Importantly, the analysis accounted for the predominantly adverse long-term impacts of these storms on economic development. The findings reveal a global increase of over 20% in the Social Cost of Carbon (from $173 to $212 per ton of CO2), and a more than 40% escalation in the assessed tropical-cyclone-prone countries, compared to the prevailing Social Cost of Carbon estimates used for policy evaluations.

In conclusion, while much attention is often directed towards the immediate economic ramifications of extreme events, it is equally vital to comprehensively assess the overall costs associated with these occurrences. This comprehensive evaluation provides societies with a more accurate understanding of the genuine costs of climate change and underscores the significance of effective climate action.
