Editing Greenhouse effect (section)

== Terminology ==
The term ''greenhouse effect'' comes from an [[wikt:analogy|analogy]] to [[greenhouse]]s. Both greenhouses and the ''greenhouse effect'' work by retaining heat from sunlight, but the way they retain heat differs. Greenhouses retain heat mainly by blocking [[convection]] (the movement of air).<ref>{{cite web |first=John |last=Worley |title=Greenhouses: Heating, Cooling and Ventilation |website=University of Georgia Extension |url=https://extension.uga.edu/publications/detail.html?number=B792&title=greenhouses-heating-cooling-and-ventilation |access-date=12 March 2023 |archive-date=12 March 2023 |archive-url=https://web.archive.org/web/20230312234640/https://extension.uga.edu/publications/detail.html?number=B792&title=greenhouses-heating-cooling-and-ventilation |url-status=live }}</ref><ref name="ipccar4wg1ch1">{{cite book |title=Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, 2007, Chapter 1 |publisher=Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA. |page=115 |url=https://www.ipcc.ch/report/ar4/wg1/ |access-date=24 March 2023 |quote=The glass walls in a greenhouse reduce airflow and increase the temperature of the air inside.
