Greenhouse Link
The greenhouse effect is connected with electromagnetic radiation, especially visible and infrared wavelengths.
Incoming Solar Radiation
The Sun sends energy toward Earth mainly in shortwave electromagnetic radiation, including visible light.
Much of this radiation passes through the atmosphere and is absorbed by Earth's surface.
Earth's Emission
The warmed Earth emits energy mainly as infrared radiation.
Greenhouse Gases
Gases such as:
carbon dioxide; water vapour; methane; nitrous oxide
absorb and re-emit some infrared radiation.
This reduces the rate at which thermal energy escapes directly to space from lower atmospheric layers and the surface.
Natural and Enhanced Effect
The natural greenhouse effect keeps Earth warm enough for life.
Increasing concentrations of greenhouse gases can strengthen this effect and contribute to long-term warming.
