The structure of the plant communities that grow on the thawing permafrost in the Arctic is changing, with grasses displacing slower-growing shrubs. Although these grasses bind more carbon dioxide than previous plant communities, they lead to far more methane emissions over the course of the year. Methane is a greenhouse gas that accelerates the global temperature rise much faster than carbon dioxide.
