Global methane concentrations rose by 15, 18, 13, and 10 ppb each year from 2020 through 2023, respectively, the second, first, fourth, and fourteenth largest increases since the U.S. National Oceanic and Atmospheric Administration (NOAA) methane time series began in 1983 (Lan et al 2024).

Methane is rising faster in relative terms than any major greenhouse gas and is now 2.6-fold higher than in pre-industrial times. Global average methane concentrations reached 1931 parts per billion (ppb) in January of 2024 (

Eine neue Studie bestätigt, dass die Hauptursache des immer schnelleren Anstiegs des Methan-Gehalts der Atmosphäre die Aktivität von Mikroaorganismen ist, die durch die globale Erhitzung zunimmt. Damit handelt es sich um einen Feedback-Mechanismus, durch den sich die globale Erhitzung selbst verstärkt. https://taz.de/Zu-viel-Methan-in-der-Atmosphaere/!6045201/
