#'@section Abstract: Greenland ice-core records provide an exceptionally clear picture of 
#' many aspects of abrupt climate changes, and particularly of those 
#' associated with the Younger Dryas event, as reviewed here. 
#' Well-preserved annual layers can be counted confidently, with only 1% 
#' errors for the age of the end of the Younger Dryas 11,500 years before 
#' present. Ice-flow corrections allow reconstruction of snow accumulation 
#' rates over tens of thousands of years with little additional uncertainty. 
#' Glaciochemical and particulate data record atmospheric-loading changes 
#' with little uncertainty introduced by changes in snow accumulation. 
#' Confident paleothermometry is provided by site-specific calibrations 
#' using ice-isotopic ratios, borehole temperatures, and gas-isotopic ratios. 
#' Near-simultaneous changes in ice-core paleoclimatic indicators of local, 
#' regional, and more-widespread climate conditions demonstrate that much 
#' of the Earth experienced abrupt climate changes synchronous with 
#' Greenland within thirty years or less. Post-Younger Dryas changes 
#' have not duplicated the size, extent and rapidity of these 
#' paleoclimatic changes.
