The '''Keeling Curve''' is a graph of the annual variation and overall accumulation of [[carbon dioxide in Earth's atmosphere|carbon dioxide in the Earth's atmosphere]] based on continuous measurements taken at the [[Mauna Loa Observatory]] on the island of [[Hawaii]] from 1958 to the present day. The curve is named for the scientist [[Charles David Keeling]], who started the monitoring program and supervised it until his death in 2005.

Keeling's measurements showed the first significant evidence of rapidly increasing [[carbon dioxide]] (CO<sub>2</sub>) levels in the atmosphere.<ref name="UCSD">{{Cite web|url=https://scrippsco2.ucsd.edu/history_legacy/early_keeling_curve.html|title=The Early Keeling Curve {{!}} Scripps CO<sub>2</sub> Program|website=scrippsco2.ucsd.edu|language=en|access-date=2018-11-24}}</ref>  According to [[Naomi Oreskes]], Professor of History of Science at [[Harvard University]], the Keeling curve is one of the most important scientific works of the 20th century.<ref name="clidis">{{cite AV media|url=https://www.youtube.com/watch?v=ENvJ2WqxNgQ |archive-url=https://ghostarchive.org/varchive/youtube/20211212/ENvJ2WqxNgQ| archive-date=2021-12-12 |url-status=live|title=Climate Disruption|date=23 January 2017|people=Naomi Oreskes|language=en|publisher=Awesome Documentaries TV|access-date=27 August 2017|medium=video}}{{cbignore}}</ref> Many scientists credit the Keeling curve with first bringing the world's attention to the current increase of {{CO2}} in the atmosphere.<ref>{{Cite journal|last=Nisbet|first=Euan|date=2007|title=Cinderella science|url=https://www.esrl.noaa.gov/gmd/co2conference/Reporters/EarthmonitoringCinderellascience_Nature.pdf|journal=Nature|volume=450|issue=7171|pages=789–790|doi=10.1038/450789a|pmid=18063983|doi-access=free}}</ref>
