Using advanced econometric techniques, the study finds that temperature shocks account for a significant share of economic fluctuations in advanced economies.

A new study from the International Monetary Fund is reshaping the debate on climate change's economic impact, suggesting that colder and wealthier countries

may be more vulnerable to long-term temperature increases than previously thought.

The paper, A New Perspective on Temperature Shocks, authored by Nooman Rebei, challenges the conventional belief that climate change primarily harms poorer, hotter countries, arguing instead that advanced economies could experience significant economic losses due to permanent shifts in temperature.

The research differentiates between temporary weather fluctuations and long-term climate changes, finding that while richer nations tend to adapt better to short-term variations, they face greater challenges in dealing with lasting climate shifts.

Using advanced econometric techniques, the study finds that temperature shocks account for a significant share of economic fluctuations in advanced economies.

Under the most severe warming scenario, these nations could see an average GDP loss of six percent by 2100, whereas emerging and developing economies may experience a more moderate decline of around one percent. This runs contrary to the widely held assumption that poorer countries, particularly those in hotter regions, will bear the brunt of climate-related economic damage.

The study highlights that historically colder regions, such as the United States, Canada, and the Nordic countries, have experienced more rapid temperature increases in recent decades.

Alongside these rising temperatures, these nations are also seeing a greater frequency of extreme weather events, including storms and wildfires, which are contributing to increased economic strain.

The findings suggest that the economic damage caused by climate change in wealthier countries is largely driven by the scale of permanent temperature shocks, rather than just temporary disruptions.

Beyond the economic effects, the study also examines the role of major greenhouse gas emitters, including the United States, China, and Germany. In some cases, it finds that economic activity in these countries contributes to emissions that, in turn, accelerate climate change, creating a self-reinforcing cycle of economic risk.

While China’s economy appears to benefit slightly from some temperature shifts, the study notes that nations like Germany and Brazil are facing heightened economic risks when factoring in the reverse relationship between emissions and economic performance.
