Trends in Global Atmospheric Methane (CH₄)
Timeplot of global atmospheric methane (CH4) showing the full NOAA record (September 1983-March 2022). This version is created with a dark background.
Timeplot of global atmospheric methane (CH4) showing the full NOAA record (September 1983-March 2022). This version is created with a light background.
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.
