Global Supply Chains Amplify Economic Costs of Future Extreme Heat Risk

This pioneering study in Nature will help you anticipate the increasing risk of heat stress on global supply chains over the medium-term (starting from 2030). Using three global warming scenarios the paper shows which countries are most impacted by health impacts and work stoppages caused to extreme heat. While these impacts disproportionately affect smaller, mid-latitude countries, the paper highlights how the economic consequences cascade through supply chains to affect manufacturing-heavy countries such as China and the USA. The paper also considers how different sectors are affected based on their where key inputs are sourced. Overall, the authors emphasize the need for heat stress adaptation across regions that are connected through supply chains.
