Combustion of fossil fuels such as coal, natural gas, and petroleum:

• releases carbon dioxide (CO₂) into the atmosphere, increasing the greenhouse effect.

• releases carbon dioxide (CO₂) and nitrogen gas into the atmosphere.

• absorbs carbon dioxide (CO₂) and nitrogen gas into the soil as carbonic acid and ammonia.

• releases water vapor into the atmosphere, increasing temperature from around the world.
