Abstract

A natural 1450-yr global Holocene climate periodicity underlies a portion of the present global warming trend. Calibrates basal radiocarbon dates from 71 palufied peatlands across the western interior of Canada demonstrate that this periodicity regulated western Canadian peatland initiation. Peatlands, the largest terrestrial carbon pool, and their carbon-budgets are sensitive to hydrological fluctuations. The AA. demonstrate that global carbon-budgets are sensitive to small climatic fluctuations; thus international agrrements on greenhouse gasses need to take into account the natural carbon-budget imbalance of regions with large climatically sensitive carbon pools
