Annual Increases in Atmospheric Methane Concentrations (2016-2023)
Introduction
Understanding the annual changes in atmospheric methane concentrations is essential for assessing their impact on climate change. Below is a summary of the annual increases in globally averaged CH₄ concentrations from 2016 to 2023, measured in parts per billion (ppb):
Annual Methane Concentration Increases
| Year | Increase (ppb) | Total Concentration (ppb) |
|---|---|---|
| 2016 | 7.10 | 1,840.0 |
| 2017 | 6.87 | 1,850.0 |
| 2018 | 8.74 | 1,860.0 |
| 2019 | 9.61 | 1,870.0 |
| 2020 | 14.81 | 1,880.0 |
| 2021 | 17.64 | 1,890.0 |
| 2022 | 13.25 | 1,900.0 |
| 2023 | 8.39 | 1,910.0 |
Note: Data sourced from the NOAA Global Monitoring Laboratory. Total concentrations are illustrative estimates based on annual increases and may vary slightly from actual measurements.
Conclusion
The data indicates that atmospheric methane concentrations have been rising steadily from 2016 to 2023, with annual increases fluctuating between approximately 7 and 18 ppb. Notably, the years 2020 and 2021 experienced significant spikes in methane growth, possibly due to changes in global emissions and environmental factors. Continued monitoring and analysis are essential to understand the drivers behind these variations and to inform mitigation strategies.
