A new paper from University of Exeter researchers argues that climate disasters can indirectly undermine a country's ability to fight global warming. The concept, called derailment risk, suggests that when storms or heatwaves hit, governments borrow heavily to rebuild. Debt payments then crowd out spending on clean energy and disaster preparedness, creating a cycle that leaves countries more vulnerable to the next shock. The paper also points to eroding public trust as a factor that makes climate action harder to sustain over time. The authors use the 2010 Russian heatwave and the resulting wheat export ban as an example of how climate shocks can ripple through food systems and trigger social unrest. They propose building resilience ahead of crises, such as better irrigation, reducing food waste, and setting rules that prevent farmland expansion into carbon-rich land when harvests fail. The paper is a conceptual argument, not a new dataset, but it highlights a blind spot in standard climate models that focus only on physical damage and economic costs. Protecting a society's ability to act may be as important as cutting emissions.
