Earth's energy budget The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. If a planet's atmosphere contains radiatively active gases (i.e., ) they will radiate energy in all directions. Part of this radiation is directed towards the surface, warming it.

The intensity of the downward radiation – that is, the strength of the greenhouse effect – will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains. Earth’s natural greenhouse effect is critical to supporting life. Human activities, mainly the burning of fossil fuels and clearing of forests, have strengthened the greenhouse effect and caused.

The term 'greenhouse effect' arose from a faulty analogy with the effect of sunlight passing through glass and warming a. Lego Harry Potter Years 1-4 Eng Spolszczenie. The way a greenhouse retains heat is fundamentally different, as a greenhouse works mostly by reducing airflow so that warm air is kept inside. Main article: The existence of the greenhouse effect was argued for by in 1824. The argument and the evidence were further strengthened by in 1827 and 1838 and reasoned from experimental observations by in 1859, who measured the radiative properties of specific greenhouse gases. The effect was more fully quantified by in 1896, who made the first quantitative prediction of global warming due to a hypothetical doubling of atmospheric carbon dioxide. However, the term 'greenhouse' was not used to refer to this effect by any of these scientists; the term was first used in this way by in 1901.

Mechanism Earth receives energy from the Sun in the form of,, and radiation. About 26% of the incoming solar energy is reflected to space by the atmosphere and clouds, and 19% is absorbed by the atmosphere and clouds. Most of the remaining energy is absorbed at the surface of Earth. Than the Sun, it radiates at than the wavelengths that were absorbed. Most of this thermal radiation is absorbed by the atmosphere and warms it. The atmosphere also gains heat by sensible and latent heat fluxes from the surface.
