Methane (CH₄) is a potent greenhouse gas. Here are the latest monthly observations...

November 2024 - 1940.75 ppb
November 2023 - 1931.75 ppb

+ Data: gml.noaa.gov/ccgg/trends_ch4/
+ More info on trends: pnas.org/doi/abs/10.1073/pnas.

Red colored line graph time series of global atmospheric methane abundance from January 1984 through November 2024. Methane abundance is measured in units of parts per billion. Current levels are 1941 ppb. A seasonal cycle is visible on the graph. There is also decadal variability and a long-term increasing trend.

@ZLabe Zack, curious now that they are closing the CO2 observatory in Hawaii, what other data sets are available? Maybe from other countries? Do you plan on reporting them? Thanks
