\nGreenhouse gases are so named because they trap heat in the Earth’s lower atmosphere in a manner analogous to how the glass walls and roof of a greenhouse trap heat.
\n<\/section>\n
\n– Greenhouse gases (such as CO\u2082, methane, water vapor) are transparent to incoming solar radiation (shortwave).
\n– The Earth’s surface absorbs this radiation and re-emits energy as infrared radiation (longwave heat).
\n– 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.
\n<\/section>\n
\n– This process is known as the greenhouse effect, a natural phenomenon essential for maintaining a habitable temperature on Earth.
\n– An increase in the concentration of greenhouse gases due to human activities enhances this effect, leading to global warming and climate change.
\n– 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.
