Global climate change has a significant impact on the world economy, reaching various sectors and affecting all countries. The earth’s rising average temperature contributes to extreme weather phenomena, such as floods, droughts and more severe storms. This not only threatens human life but also affects global economic productivity. Agriculture is one of the sectors most vulnerable to climate change. With erratic rainfall patterns and extreme temperatures, crop yields are unpredictable. For example, several rice-producing regions in Southeast Asia experienced a significant decline in production, which then had an impact on international food prices. Rising food prices can cause inflation and increase economic uncertainty for countries that depend on food imports. The energy sector has also been impacted, especially those dependent on natural resources. Climate change creates new challenges in water management for hydroelectric power plants and causes infrastructure damage due to natural disasters. Additionally, demand for renewable energy is increasing along with global efforts to reduce carbon emissions. Companies that invest in green technologies will gain a competitive advantage, while those that don’t adapt risk being left behind. The tourism industry, a source of income for many countries, has also been impacted. Tourist destinations that are affected by climate change, such as low-lying islands that are threatened with sinking or beaches that are experiencing erosion, will lose their appeal. This could lead to a decrease in visitors and, in turn, harm the local economy. Loss of income from the tourism sector can affect people’s jobs and incomes, exacerbating economic injustice. On the other hand, climate change also encourages innovation and job creation in the green technology sector. Businesses that focus on sustainable solutions, such as waste management and renewable energy production, are increasingly in demand. Investments in green technology can create new jobs and drive economic growth, providing an opportunity for countries to transition to a more sustainable economy. Climate change also affects public health and the associated costs. Vector-borne diseases, such as malaria and dengue fever, are expected to increase with climate change, which in turn could strain health systems and workforce productivity. Rising health costs will reduce people’s purchasing power, slowing economic growth. Countries least prepared to deal with climate change, especially in the global south, could experience the most severe impacts. Limited resources and inadequate infrastructure make them more vulnerable to economic losses. Intervention by international organizations to support adaptation and mitigation is essential to ensure that these countries do not become trapped in a cycle of poverty exacerbated by the climate crisis. By considering all the impacts above, it is clear that global climate change demands serious attention from governments, business actors and civil society. Joint efforts are needed to reduce greenhouse gas emissions and plan adaptation so that the global economy can survive and develop amidst increasingly complex challenges.
