Understanding the Carbon Cycle: How Human Activities Affect Atmospheric Carbon Dioxide

Abstract

Chibuike Onwukwe

The carbon cycle is a fundamental biogeochemical cycle that regulates the movement of carbon through the Earth's atmosphere, oceans, soil, and living organisms. It is essential for maintaining the balance of carbon dioxide (CO₂) in the atmosphere and supporting life on Earth. However, human activities have significantly disrupted this natural cycle, leading to increased atmospheric CO₂ levels and contributing to global climate change. This paper explores the dynamics of the carbon cycle, focusing on how human activities such as fossil fuel combustion, deforestation, and industrial processes have altered atmospheric CO₂ concentrations. We review the current understanding of carbon fluxes between different reservoirs and the impact of anthropogenic emissions on global climate systems. The discussion includes the implications of rising atmospheric CO₂ for climate change, ecosystem health, and the broader environment. Finally, we outline potential mitigation strategies and future research directions to address the challenges posed by increased atmospheric CO₂. By examining recent research and current understanding, the paper aims to highlight the urgent need for effective mitigation strategies and policy interventions to address the challenges posed by elevated CO₂ levels. The discussion also emphasizes the importance of integrating scientific knowledge with practical approaches to manage and stabilize the carbon cycle for the benefit of global ecosystems and human societies.
