Abstract The abstract describing the content of the publication or report |
For interpreting past changes on a regional or global scale, the timings of proxy-inferred events are usually aligned with data from other locations. However it is argued that too often chronological uncertainties are ignored in proxy diagrams and multisite comparisons, making it possible for researchers to fall into the trap of sucking separate events into one illusionary event (or vice versa). In this paper the authors largely solve what is termed the `suck in and smear syndrome' for radiocarbon (14C) dated sequences. In a Bayesian framework, millions of plausible age-models are constructed to quantify the chronological uncertainties within and between proxy archives. The authors test the technique on replicated high-resolution 14C-dated peat cores deposited during the `Little Ice Age' (c. AD 1400--1900), a period characterized by abrupt climate changes and severe 14C calibration problems. Owing to internal variability in proxy data and uncertainties in age-models, these (and possibly many more) archives are not consistent in recording decadal climate change. Through explicit statistical tests of palaeoenvironmental hypotheses, it is possible to move forward to systematic interpretations of proxy data. However, chronological uncertainties of non-annually resolved palaeoclimate records are too large for answering decadal timescale questions. | ||||
