Graphic shows three line graph time series of monthly carbon dioxide abundance in ppm (blue line), monthly methane abundance in ppb (red line), and monthly nitrous oxide in ppb (purple line). Graphs are all shown from January 1984 through February 2024/November 2023. Current levels of carbon dioxide are 425 ppm. Current levels of methane are 1934 ppb. Current levels of nitrous oxide are 337 ppb. All graphs show long-term increasing trends along with some interannual variability and seasonality.
