In thawing Arctic permafrost soils, carbon dioxide is produced by microbes in dry conditions, while both methane and carbon dioxide are produced by microbes in wet conditions. Artwork by Victor Leshyk.

When it comes to climate change, not all carbon is created equal. Among greenhouse gases, methane is 34 times more potent than carbon dioxide.

In this recent study published in Nature Climate Change, Northern Arizona University assistant research professor and lead author of the study, Christina Schädel, analyzed carbon release from 25 Arctic soil incubation studies to learn more about the conditions promoting either carbon dioxide or methane release.
