CO2 impacts the atmosphere because it causes temperatures to slowly rise over time. Oxygen produced from plants counter act CO2 with the carbon dioxide exchange but it still impacts the atmosphere to a certain level. it affects oceanic areas because it causes sea levels to rise, as well as increase the acidic levels in the water. hope this helps!
