Greenhouse gas - Wikipedia
Greenhouse gases (GHGs) are the gases in an atmosphere that trap heat, raising the surface temperature of astronomical bodies such as Earth. Unlike other gases, greenhouse gases absorb the radiations that a planet emits, resulting in the greenhouse effect. [1]
What Are Greenhouse Gases and Why Do They Matter
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).
Overview of Greenhouse Gases | US EPA
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.
Greenhouse gas | Definition, Emissions, & Greenhouse Effect | Britannica
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.
Greenhouse Gases – Definition, Types, and Environmental Impact
Greenhouse gases trap heat in Earth’s atmosphere and drive climate change. Discover their properties, sources, lifetimes, and effects.
What is the greenhouse effect? - Science@NASA
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.
Greenhouse Gases - MIT Climate Portal
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.
The Greenhouse Effect and our Planet - Education
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.
Greenhouse gases - U.S. Energy Information Administration (EIA)
Greenhouse gases absorb this infrared radiation and trap its heat in the atmosphere, creating a greenhouse effect that results in global warming and climate change.
Greenhouse gases - World Meteorological Organization
Greenhouse gases (GHGs) in the atmosphere trap infrared radiation from the Earth, keeping it warm, this is known as the greenhouse effect. GHG emissions from human activities provided the majority contribution towards global warming of 1.1 °C.
