Why is the carbon concentration present in the atmosphere is rising?

The rising carbon concentration in the atmosphere is primarily due to human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas for energy and transportation. Deforestation and land-use changes also contribute by reducing the number of trees that can absorb carbon dioxide. Additionally, industrial processes release significant amounts of carbon emissions. These factors combined have led to an increase in atmospheric carbon levels, exacerbating climate change.
