Abstract

The feedback between the terrestrial carbon cycle and climate is one of the largest uncertainties in current projections of future climate, with the long-term sensitivity of carbon in peatlands remaining unclear. The combination of non-disturbing in situ measurements of carbon dioxide respiration rates and isotopic composition of respired CO2 in subarctic peatland experiments now shows that warming accelerates respiration rates of these subsurface carbon reservoirs to a much larger extent than was previously thought.
