Which correlates CLOSEST with the net increase in CO₂ levels over the past two centuries?

Question

Quizplus · Accepted Answer

The significant increase in CO2 levels over the past two centuries is primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. This has resulted in a significant increase in atmospheric CO2 levels, which is the closest correlation to the net increase in CO2 levels over the past two centuries. Volcanic gases and respiration also release CO2 into the atmosphere, but their contribution to the net increase in CO2 levels over the past two centuries is comparatively small. Carbon dissolved in the oceans also contributes to the carbon cycle, but it does not explain the significant increase in atmospheric CO2 levels.
