Data Sources:

  • Trends in Athmospheric Methane by NOAA. The visualizations featured on this page utilize the complete record from the Globally averaged marine surface monthly mean data for the period July 1983-March 2022 (accessed: August 4, 2022). Within the data record the globally averaged monthly mean values are centered on the middle of each month and are represented in the visualization as the jagged/wavy Average line. The continuous line shows the long-term Trend, where the average seasonal cycle has been removed.
