Ellen G. R. B. Keeling

Ellen G. R. B. Keeling was an influential climate scientist known for her research on atmospheric carbon dioxide levels. She co-developed the Keeling Curve, a precise record of CO₂ concentrations measured at Mauna Loa Observatory from the late 1950s onward. This graph clearly shows a steady increase in global CO₂ levels due to human activities like burning fossil fuels. Her work provided crucial evidence of ongoing climate change, helping scientists and policymakers understand the relationship between greenhouse gases and global warming, ultimately highlighting the importance of reducing carbon emissions for environmental health.
