Why Is Carbon Dioxide a Pollutant?

Carbon dioxide contributes to air pollution in its role in the greenhouse effect. Carbon dioxide traps radiation at ground level, creating ground-level ozone. This atmospheric layer prevents the earth from cooling at night. One result is a warming of ocean waters.

Why is carbon dioxide considered as a pollutant?

In its decision, the EPA stressed that it considers CO2 and other so-called greenhouse gases to be pollutants because of their role in propagating climate change, not because of any direct health effects. ... But despite continued pressure from environmental groups, the administration never moved to regulate the gases.

Why is carbon dioxide bad for the environment?

As a greenhouse gas, excessive CO2 creates a cover that traps the sun's heat energy in the atmospheric bubble, warming the planet and the oceans. An increase in CO2 plays havoc with the Earth's climates by causing changes in weather patterns.
