Quizplus · Accepted Answer

Carbon dioxide is the gas primarily responsible for the greenhouse effect and contributes to global warming. Its concentration in the atmosphere has increased significantly due to human activities such as burning fossil fuels and deforestation. This trend is a symptom of growing industrialization around the globe. Carbon monoxide is also a product of burning fossil fuels, but is not directly linked to the greenhouse effect. Sulfur dioxide and nitric acid are air pollutants that contribute to acid rain, but do not significantly affect the greenhouse effect.
