Charles David Keeling
Charles David Keeling was an American scientist renowned for his groundbreaking work in atmospheric physics, particularly for initiating the systematic measurement of carbon dioxide (CO2) levels in the Earth's atmosphere. In 1958, he began collecting data at the Mauna Loa Observatory in Hawaii, producing the Keeling Curve, which graphically illustrates the rise in CO2 concentrations over time. His research provided critical evidence of human-induced climate change, highlighting the relationship between fossil fuel combustion and increasing greenhouse gas levels, thus enhancing our understanding of global warming and its impacts on the environment.
