Charles David Keeling (oceanographer)

Charles David Keeling was an influential oceanographer and climate scientist best known for his precise measurements of atmospheric carbon dioxide (CO₂) levels. He developed a method and established the Keeling Curve, which shows how CO₂ concentrations have increased over time due to human activities like burning fossil fuels. His work provided critical evidence of the link between CO₂ emissions and climate change, helping scientists understand how greenhouse gases affect Earth's climate system. Keeling’s research laid the foundation for ongoing climate monitoring and underscored the importance of reducing CO₂ emissions to mitigate climate change.
