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.
Wetland restoration is often promoted as a definitive way to support wildlife, improve water quality and help store carbon. However, new research from McGill University suggests the overall climate picture is more complicated. ...
