Google Doodle today celebrates the 204th birthday of Eunice Newton Foote, an American scientist who is credited with discovering the greenhouse effect. Foote was born in Hartford, Connecticut, in 1819. She was a self-taught scientist who conducted experiments on the absorption of heat by different gases. In 1856, she published a paper in the American Journal of Science and Arts in which she described her experiments and concluded that carbon dioxide and water vapor trap heat in the atmosphere, causing the greenhouse effect.

Foote’s Experiments

Foote’s experiments were simple but ingenious. She used two glass cylinders, each with a thermometer inside. She filled one cylinder with air and the other with carbon dioxide. She then placed both cylinders in sunlight. The thermometer in the cylinder filled with carbon dioxide registered a higher temperature than the thermometer in the cylinder filled with air. This showed that carbon dioxide traps heat in the atmosphere.

The Greenhouse Effect

The greenhouse effect is a natural process that keeps the Earth’s temperature warm. The atmosphere is made up of gases that trap heat from the sun. These gases include carbon dioxide, water vapor, and methane. The greenhouse effect is essential for life on Earth, but it can also be a problem if it gets too strong.

Foote’s Legacy

Eunice Newton Foote’s work was ahead of its time. She was one of the first scientists to understand the greenhouse effect and its potential impact on the Earth’s climate. Her work helped to pave the way for future research on climate change.
