Simplified diagram showing how Earth transforms sunlight into infrared energy. Greenhouse gases like carbon dioxide and methane absorb the infrared energy, re-emitting some of it back toward Earth and some of it out into space.
Diagramme décrivant comment la Terre transforme les rayons solaires en énergie infrarouge. Les gaz à effet de serre comme le dioxyde de carbone absorbent l'énergie infrarouge, émettant à nouveau une partie au sol, et expulsant le reste dans l'espace.
