  • Winter warming in Alaska accelerates lignin decomposition

    Jun 05, 2020Nearly half of global soil organic C is stored in the northern permafrost regions (1330–1580 Pg organic C) [1, 2].With rapid increase of temperature occurring in higher latitudes, this large C pool becomes vulnerable to microbial decomposition [].It was shown that an increase of 2 &C would accelerate the decomposition of chemically recalcitrant C by 21%, compared with only a 10%
