The primary driver of climate variability is the intricate interplay of natural and anthropogenic factors, with notable influences from greenhouse gases, solar radiation, and ocean currents. Human activities, such as burning fossil fuels and deforestation, contribute to increased concentrations of greenhouse gases, trapping heat in the atmosphere. Natural phenomena like El Niño and volcanic eruptions also significantly affect climate patterns. Understanding these drivers is vital for predicting future climate changes and developing strategies for mitigation and adaptation.
