Keeling Curve

The Keeling Curve is a graph that shows the concentration of carbon dioxide (CO₂) in Earth's atmosphere over time. Named after scientist Charles David Keeling, it reveals a steady upward trend, indicating increasing CO₂ levels. The curve also displays seasonal fluctuations caused by natural processes like plant growth. This data helps scientists understand human impacts on climate change, as rising CO₂ levels are linked to global warming. The Keeling Curve provides crucial evidence of how our actions influence the atmosphere, emphasizing the importance of reducing greenhouse gas emissions.
