John Tyndall was a British physicist known for his research on radiant heat and its absorption by various gases, notably water vapor and carbon dioxide. This research was instrumental in understanding the greenhouse effect and its role in moderating Earth’s climate. Tyndall demonstrated that these gases absorb radiant heat, contributing to the warming of the Earth’s atmosphere.
