"For the second year in a row, NOAA scientists observed a record annual
increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse
gas that’s the second biggest contributor to human-caused global warming after
carbon dioxide.
NOAA’s preliminary analysis showed the annual increase in atmospheric methane
during 2021 was 17 parts per billion (ppb), the largest annual increase
recorded since systematic measurements began in 1983. The increase during 2020
was 15.3 ppb. Atmospheric methane levels averaged 1,895.7 ppb during 2021, or
around 162% greater than pre-industrial levels. From NOAA’s observations,
scientists estimate global methane emissions in 2021 are 15% higher than the
1984-2006 period."
