The impact of coal burning on climate change is it contributes to global warming through carbon dioxide emissions.

Burning coal for energy is one of the leading contributors to climate change. Coal is rich in carbon, and when burned, it releases large amounts of carbon dioxide (CO2) into the atmosphere. CO2 is a greenhouse gas, which traps heat and causes the Earth's temperature to rise, contributing to global warming. Coal combustion also produces other pollutants like sulfur dioxide and nitrogen oxides, which can worsen air quality and contribute to smog and acid rain. The impact of coal on the climate is significant, making it a key focus of efforts to reduce global emissions and mitigate climate change.
