A strong mitigation scenario maintains climate neutrality of northern peatlands

International audience Highlights d Northern peatlands remain a CO 2 sink of $0.1 Pg C year À1 until 2300 under RCP2.6 d Northern peatlands become a CO 2 source of $0.2 Pg C year À1 by 2300 under RCP8.5 d CH 4 emissions from northern peatlands will increase 5-fold by 2300 under RCP8.5 d Modeling of...
