Therefore, this study aims to analyze the heterogeneous effects of climate change on output across the manufacturing subsectors in Nigeria from 1990 to 2021. The fully modified ordinary least squares method is used to analyze the time series data, and canonical cointegrating regression, along with diagnostic tests (normality and Wald restriction tests), is conducted to check the robustness of the models. The empirical results reveal that climate change has a significant negative effect on manufacturing output at the aggregate level and across the manufacturing subsectors. The adverse effect is particularly strong for Textile, Apparel and Footwear, Plastic and Rubber Products, and Chemical and Pharmaceutical Products subsectors. Moreover, the study finds that manufacturing output at the aggregate level and across the manufacturing subsectors responds negatively to exchange rate and positively to labor and capital. Based on the results, the study recommends that the government should discourage fossil fuel consumption and promote renewable energy consumption such as solar, wind, hydro, and geothermal to slow climate change. Also, the government needs to implement structural reforms to reduce reliance on foreign inputs and final products, enhance domestic production and exportation, increase foreign reserves, and strengthen the Nigerian currency. https://ier.ut.ac.ir/article_97074_95eb83542315080493f9a00e01920fe6.pdf
