Greenhouse gases are atmospheric constituents that absorb and emit infrared radiation, thereby contributing to the greenhouse effect and Earth’s radiative energy balance. Major greenhouse gases include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), ozone (O₃), and various halogenated compounds, along with water vapour (H₂O) as a feedback agent. Their radiative forcing depends on concentration, spectral absorption properties, atmospheric lifetime, and overlap with other absorbers. In climate research, greenhouse gases are quantified via metrics such as global warming potential and effective radiative forcing to assess their contribution to anthropogenic climate change and to inform emissions mitigation strategies.
Tropical inland waters don't produce as many greenhouse gas (GHG) emissions as previously estimated, according to the results of an international research collaboration led by Charles Darwin University (CDU).
