: For the past half century, the Scripps Institution of Oceanography has been maintaining the Keeling curve
, a measurement of atmospheric carbon dioxide. But because of decreased government funding, institution officials turned to Twitter last month to try to crowdsource donations to keep the program running. Although the National Oceanic and Atmospheric Administration also maintains a data-gathering network that overlaps the program run by Scripps, NOAA does not replicate another of Scripps’s databases, its atmospheric-oxygen record. Both databases are important for monitoring the decreasing oxygen and increasing CO2
levels caused by fossil-fuel combustion, which has been shown to contribute to global warming.
