abstract = {Peatlands are a major terrestrial carbon store and a
persistent natural carbon sink during the Holocene, but
there is considerable uncertainty over the fate of peatland
carbon in a changing climate. It is generally assumed that
higher temperatures will increase peat decay, causing a
positive feedback to climate warming and contributing to the
global positive carbon cycle feedback. Here we use a new
extensive database of peat profiles across northern high
latitudes to examine spatial and temporal patterns of carbon
accumulation over the past millennium. Opposite to
expectations, our results indicate a small negative carbon
cycle feedback from past changes in the long-term
accumulation rates of northern peatlands. Total carbon
accumulated over the last 1000 yr is linearly related to
contemporary growing season length and photosynthetically
active radiation, suggesting that variability in net primary
productivity is more important than decomposition in
determining long-term carbon accumulation. Furthermore,
northern peatland carbon sequestration rate declined over
the climate transition from the Medieval Climate Anomaly
(MCA) to the Little Ice Age (LIA), probably because of lower
LIA temperatures combined with increased cloudiness
suppressing net primary productivity. Other factors
including changing moisture status, peatland distribution,
fire, nitrogen deposition, permafrost thaw and methane
emissions will also influence future peatland carbon cycle
feedbacks, but our data suggest that the carbon
sequestration rate could increase over many areas of
northern peatlands in a warmer future.},
