Physical Climate Risks and Energy Transition Vulnerability in China’s Resource-Based Cities: Dynamic Disturbances, Probabilistic Forecasting, and Stress Testing
Using panel data from 63 Chinese resource-based cities (2011–2023), this study employs dynamic modeling and probabilistic forecasting to reveal that while physical climate risks do not alter the structural level of energy transition vulnerability, they significantly disrupt its annual improvement trajectory by hindering adaptive capacity, offsetting approximately 14.3% of progress, though the evidence for strong causal inference and moderating effects remains limited.

Cities built around coal mines, oil fields, and metal deposits face a unique double bind. They are tasked with the difficult job of shifting away from the very resources that built their economies, a process known as the energy transition. At the same time, they are increasingly battered by the physical realities of a changing climate, such as extreme heat, cold, floods, and droughts. While scientists have long studied how these cities perform in their shift toward clean energy, and how climate disasters damage power grids, a critical question remained unanswered: do these climate shocks actually slow down the city's progress toward a greener future? Most previous studies looked at a city's vulnerability as a static snapshot, like a photograph of a building's condition. But cities are always changing, and a disaster might not immediately collapse a building; instead, it might just stop the construction crew from finishing their work for the year. Understanding whether climate risks are merely damaging the structure or simply halting the renovation is essential for planning a safe and steady transition.
A team of researchers set out to investigate this dynamic relationship across 63 resource-based cities in China, tracking their progress from 2011 to 2023. They focused on a concept called "energy transition vulnerability," which measures how easily a city's shift to clean energy could be disrupted. To get a clear picture, they split this vulnerability into two parts: the pressure the city feels to change, such as its heavy reliance on old industries, and its adaptive capacity, which is the city's ability to learn, invest, and adjust to new conditions. By combining data on weather extremes with economic and social statistics, they built a model to see if a bad weather year actually made the city more vulnerable, or if it simply paused the city's usual yearly improvements.
The researchers found that physical climate risks do not typically cause a sudden, massive jump in a city's overall vulnerability level in the year the disaster strikes. Instead, the impact is more subtle and insidious. When a city faces a year with significantly higher climate risks—defined as a one-standard-deviation increase in extreme weather events—it does not necessarily become more vulnerable in an absolute sense. Rather, the city's progress toward becoming less vulnerable slows down. On average, a spike in climate risk cancels out about 14.3 percent of the improvement a city would have made that year. It is as if a city is climbing a hill toward a safer future, and a climate shock doesn't push it back down the mountain, but it does make it stop climbing for a while, erasing a significant chunk of the distance it would have covered.
Digging deeper into why this slowdown happens, the study revealed that the main culprit is not the pressure to change, but the city's ability to adapt. The researchers discovered that the obstruction of improvement comes almost entirely from a stall in adaptive capacity. In other words, climate shocks do not necessarily make the industrial pressure worse in the short term; instead, they drain the city's resources and energy, making it harder to upgrade infrastructure, train workers, or invest in new technologies. This loss of momentum accounts for roughly 70 percent of the negative effect. The study also tested whether having more green money or better connections to other cities' technology networks could buffer this blow. The data showed that while these factors are generally helpful, they did not provide a statistically reliable shield against the specific short-term slowdown caused by climate shocks in this dataset.
Looking ahead, the researchers used their findings to forecast what might happen in 2024. Their model, which accounts for the complex ways cities evolve over time, suggests that the overall trend for these 63 cities will continue to be one of moderate improvement. The average vulnerability is expected to decrease slightly, meaning the cities are still moving in the right direction. However, the forecast comes with a crucial warning: while the average looks good, there is still a real chance that individual cities could see their progress reverse. The model estimates that about 22 percent of the time, a city might actually get worse instead of better. This uncertainty highlights that while the general path is upward, the journey is not smooth, and some cities are at risk of stalling or sliding back.
To understand how robust these predictions are, the team subjected their forecast to a stress test, simulating what would happen if climate risks were significantly higher than usual. They imagined scenarios where extreme weather events were half a standard deviation, one standard deviation, or even two standard deviations more intense than normal. Even under these severe conditions, the overall system did not collapse or reverse direction. The average improvement path remained stable, though the specific reasons for the outcome shifted. The analysis showed that under high stress, the volatility of the weather—how unpredictable and erratic the conditions become—becomes the dominant factor influencing the outcome, rather than just the average amount of heat or rain. This suggests that the unpredictability of climate events is a key driver of risk, capable of creating different outcomes for different cities even when the average risk is the same.
The study concludes that managing the energy transition in resource-based cities requires a shift in perspective. It is not enough to look at a city's current vulnerability score and assume it is fixed. Instead, policymakers must monitor the speed of improvement. A city might look stable today, but if climate shocks are consistently slowing down its annual progress, it is effectively losing ground. The most effective strategy, the authors suggest, is to focus on strengthening a city's adaptive capacity—its ability to absorb shocks and keep moving forward. This means building infrastructure that can withstand extreme weather, ensuring that funds for green projects are actually used to build resilience, and recognizing that the goal is not just to reach a destination, but to ensure the journey is not constantly interrupted by the weather. By understanding that climate risks act as a brake on progress rather than just a sudden crash, cities can better prepare to keep their transition on track.
