NOAA’s October 2021 global mean methane reading is 1907.2 parts per billion (ppb), which is 17.1 ppb higher than the reading for October 2020. By comparison, NOAA’s annual global mean methane increase of 15.74 ppb for 2020 was at the time the highest on record.
Keep in mind that this 1907.2 ppb reading is for October 2021; it now is February 2022. Furthermore, NOAA’s data are for marine surface measurements; more methane tends to accumulate at higher altitudes.
The situation is dire and calls for the most comprehensive and effective action, as described at the Climate Plan.
