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.
Each year, the world's leading climate scientists evaluate the most critical evidence on how our planet is changing. Their assessments draw heavily on data from Earth-observing satellites—and the latest report delivers a ...
