WebWhat are greenhouse gases? Greenhouse gases (GHGs) trap part of the sun’s heat within the Earth’s atmosphere. While much of the sun’s energy reflects off the Earth’s surface and escapes back into space, greenhouse gases effectively capture some of this energy, reflect it, and thereby warm the planet.
