Learning Objective
I can interpret Keeling's Curve to analyze trends in atmospheric carbon dioxide and discuss potential effects on Earth's climate.
- 1
Keeling's Curve shows the ongoing change in the concentration of carbon dioxide in Earth's atmosphere since 1958.
- 2
The upward trend in Keeling's Curve is primarily due to the burning of fossil fuels, deforestation, and industrial processes.
- 3
Keeling's Curve shows a seasonal cycle where CO₂ levels dip during the Northern Hemisphere's summer and rise in the fall and winter.
