TL;DR: It is demonstrated using stable carbon isotopes that methane is readily formed in situ in terrestrial plants under oxic conditions by a hitherto unrecognized process, suggesting that this newly identified source may have important implications for the global methane budget and may call for a reconsideration of the role of natural methane sources in past climate change.

TL;DR: Results clearly demonstrate that ester methyl groups of pectin can serve as a precursor ofCH4, supporting the idea of a novel chemical route of CH4 formation in plants under oxic environmental conditions.

TL;DR: In this article, a Rayleigh model was used to account for the isotopic fractionations in the photochemical chain reactions from CH4 to the final product H2O via H2 reveals a strong enrichment of photochemically produced H2.

TL;DR: In this paper, the first set of vertically resolved fractional release factors for 15 long-lived halocarbons in the tropical stratosphere up to 34 km altitude were calculated from measurements on air samples collected on board balloons and a high altitude aircraft.
