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.

Moderate volcanic eruptions and extreme wildfires since 2005 have led to an increase in the amount of water vapor in the stratosphere, a layer of Earth's atmosphere above the weather-filled troposphere. That's potentially ...
A newer "climate-friendly" refrigerant used in car air conditioning systems may already be a significant, and possibly dominant, source of a "forever chemical" pollutant across Europe, according to a new University of Bristol-led ...
