Question

Examlex · Accepted Answer

The Answer is Atmospheric carbon dioxide (CO2) is primarily sourced from human activities such as burning fossil fuels, deforestation, and industrial processes. Natural sources of CO2 include volcanic eruptions, respiration by living organisms, and the decay of organic matter.

Sinks for atmospheric CO2 include the oceans, where CO2 is absorbed and stored in the form of carbonic acid, and terrestrial vegetation, which takes in CO2 during photosynthesis. Additionally, CO2 is removed from the atmosphere through chemical weathering of rocks.

The greenhouse effect occurs when CO2 and other greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in global temperatures. This effect is essential for maintaining the Earth's temperature within a habitable range. However, human activities have significantly increased the concentration of CO2 in the atmosphere, leading to enhanced greenhouse warming and climate change.

The role of atmospheric CO2 in the greenhouse effect is to absorb and re-emit infrared radiation, effectively trapping heat in the atmosphere. This leads to an increase in global temperatures, changes in weather patterns, and impacts on ecosystems and human societies. Efforts to mitigate the effects of atmospheric CO2 include reducing emissions through sustainable energy practices, reforestation, and carbon capture and storage technologies.
