Whose idea introduced the greenhouse effect in climate science?

John Tyndall, an Irish physicist, is the scientist most closely associated with the early explanation of the greenhouse effect. In 1859 he used laboratory experiments to show that gases such as water vapor, carbon dioxide, and methane absorb infrared radiation far more strongly than dry air. This was a major breakthrough in understanding why Earth stays warm enough for life. Tyndall’s work in the 19th century became a foundation for later climate science, including the study of human-caused warming.
