– The Earth’s surface absorbs this radiation and re-emits energy as infrared radiation (longwave heat).
– Greenhouse gases absorb this outgoing infrared radiation and re-emit it in all directions, including back towards the Earth’s surface, thus trapping heat and warming the planet.
– An increase in the concentration of greenhouse gases due to human activities enhances this effect, leading to global warming and climate change.
– The analogy with a greenhouse is not perfect (a real greenhouse also traps heat by preventing convective heat loss), but it effectively describes the trapping of infrared radiation.
