We are driven to investigate how climate change impacts the prosperity of forestry firms. We propose that there are interconnected links between climate change, forest ecosystems, forest economies, and forestry firms. Our research shows that global warming leads to the destruction of forests due to droughts, pests, and wildfires. These climate events prompt government policies regarding harvesting, which in turn affect firms by increasing production costs, leading to a decline in profitability and fluctuations in stock market performance. Our findings establish causal connections between rising global temperatures and both cash flows in firms and industry stock market returns. Given these concerning negative trends, the challenging effects of climate change on the forestry sector are likely to worsen, posing serious risks to the sustainability of firms, individuals, and communities that rely on forests. The implications for life in the forestry sector are nothing short of existential.
