Article Description

Peatlands have acted as net CO sinks over millennia, exerting a global climate cooling effect. Rapid warming at northern latitudes, where peatlands are abundant, can disturb their CO sink function. Here we show that sensitivity of peatland net CO exchange to warming changes in sign and magnitude across seasons, resulting in complex net CO sink responses. We use multiannual net CO exchange observations from 20 northern peatlands to show that warmer early summers are linked to increased net CO uptake, while warmer late summers lead to decreased net CO uptake. Thus, net CO sinks of peatlands in regions experiencing early summer warming, such as central Siberia, are more likely to persist under warmer climate conditions than are those in other regions. Our results will be useful to improve the design of future warming experiments and to better interpret large-scale trends in peatland net CO uptake over the coming few decades.
