Transcript of The Process
The "greenhouse effect" of the atmosphere is named by analogy to greenhouses which get warmer in sunlight, but the mechanism by which the atmosphere retains heat is different.
The greenhouse effect is a process by which thermal radiation from the planetary surface is absorbed by the atmospheric green houses, and re-radiated in all directions.
The existence of the greenhouse effect was argued for by Joseph Fourier in 1824. The argument and the evidence was further strengthened by Claude Pouillet in 1827 and 1838, and reasoned from experimental observations by John Tyndall in 1859, and more fully quantified by Svante Arrhenius in 1896.
The Earth receives energy from the Sun in the form UV, visible, and near IR radiation, most of which passes through the atmosphere without being absorbed.
Although the greenhouse effect is a nature cycle, humans have greatly increased the concentrations of greenhouse gases, thus causing a significant increase in the overall greenhouse effect.
