Greenhouse gases (GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. Unlike other gases, greenhouse gases absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. [1] .

Oct 12, 2022 · Greenhouse gases (GHGs) are a category of gases that absorb heat energy emitted from the planet's surface and they remain in Earth's atmosphere for a long time (from decades to centuries).

Apr 11, 2025 · greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases.

Jan 16, 2025 · Gases that trap heat in the atmosphere are called greenhouse gases. This section provides information on emissions and removals of the main greenhouse gases to and from the atmosphere. Click on a greenhouse gas below to learn about its emissions in more detail.

May 22, 2023 · Greenhouse gases are gases—like carbon dioxide (CO 2), methane, and nitrous oxide—that keep the Earth warmer than it would be without them. The reason they warm the Earth has to do with the way energy enters and leaves our atmosphere. When energy from the sun first reaches us, it does so mainly as light.

Jun 1, 2022 · Greenhouse gases are molecules in our atmosphere that absorb heat radiating from Earth’s surface, preventing it from being emitted into space. The most common greenhouse gases are (in order of atmospheric concentration) water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and a suite of halogen-bearing gases (like ...

Oct 23, 2024 · The greenhouse effect is the process through which heat is trapped near Earth's surface by substances known as 'greenhouse gases.' Imagine these gases as a cozy blanket enveloping our planet, helping to maintain a warmer temperature than it would have otherwise.

May 13, 2019 · Carbon dioxide, a key greenhouse gas that drives global climate change, continues to rise every month. Find out the dangerous role it and other gases play. By trapping heat from the sun,...

Mar 18, 2024 · Carbon dioxide, water vapor, and several other important greenhouse gases contribute to global warming via the so-called greenhouse effect. There's a whole family of greenhouse gases (GHGs). But an important thing to remember is …

Dec 9, 2024 · The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth’s atmosphere. Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), and fluorinated gases.
