Theories about climate change: Learn about scientists’ efforts to explain the phenomenon – Egypt Today

CAIRO – 8 November 2022: There are several theories on the subject of climate change including the effect of greenhouses and global warming.

The meaning and importance of climate change are not clear to many, but the following theories reflect the efforts of scientists over the years to explain the phenomenon.

The greenhouse effect

In the 1820s, the French mathematician and physicist Joseph Fourier suggested that the energy that reaches the planet as sunlight must be balanced with energy returning to space because hot surfaces emit radiation.

However, Fourier believed that some of this energy should stay in the atmosphere and not return to space, keeping the Earth warm.

Fourier believed, according to History, the Earth's thin covering of air (atmosphere) works the way a greenhouse does. Energy enters through glass walls, but is trapped inside, like a warm greenhouse.

This theory was further explored by the work of Eunice Newton Foote in the 1850s. Foote's experiments using glass cylinders have shown that the heating effect of the sun was greater in moist air than in dry air and that the highest heating occurred in a cylinder containing carbon dioxide. Her work foreshadowed the work of Irish scientist John Tyndall who also focused on the types
