The Keeling Curve is a graph that depicts the amount of carbon dioxide in Earth’s atmosphere every day since 1958. It shows the ongoing increase in carbon dioxide in the atmosphere, alongside the seasonal variation in CO2 levels. The curve is named after Charles David Keeling, who began the monitoring program in 1958. He was the first person to make regular measurements of carbon dioxide in Earth’s atmosphere.
