Advisor: Richard McGehee. 1 computer file (PDF); v, 29 pages.The COVID-19 pandemic has caused a decrease in carbon dioxide emissions. Here we will look at the atmospheric carbon dioxide, carbon-13, and carbon dioxide emissions data in order to determine whether the drop in emissions had an effecton atmospheric carbon dioxide and carbon-13. For carbon dioxide and carbon-13, we look at the trend and the seasonal pattern. To find whether 2020 is an outlier, we find the average values and compare them to previous years, as well as compare the monthly data. The data in 2020 for the atmospheric carbon dioxide and carbon-13 did not show a drop, and was not an outlier.enAtmosphereCarbonCarbon-13ClimateEmissionsPandemicThesis or Dissertation
