Published by means of the yank Geophysical Union as a part of the Geophysical Monograph Series.Abrupt weather swap: Mechanisms, styles, and Impacts brings jointly a various crew of paleoproxy documents equivalent to ice cores, marine sediments, terrestrial (lakes and speleothems) documents, and paired ocean-atmosphere weather versions to record fresh advances in knowing the mechanisms of abrupt weather alterations. because the discovery of the Dansgaard-Oeschger occasions in Greenland ice cores and the following discovery in their modern occasions within the marine sediments of the North Atlantic, the quest for those abrupt, millennial-scale occasions around the globe has intensified, and accordingly, the variety of paleoclimatic documents chronicling such occasions has elevated. the amount highlights contain discussions of documents of prior weather variability, meridional overturning...

These climate perturbations are known as the Dansgaard-Oeschger (D-O) warming and cooling cycles of 2–3 kyr duration. These are bundled into Bond cycles of 5–10 kyr and are terminated by Heinrich events consisting of massive iceberg rafting from the late Pleistocene Laurentide Ice Sheet (LIS). Since the discovery of the D-O cycles in ice cores and their counterparts in marine sediments of the North Atlantic, the search for abrupt, millennial- or finer-scale events has intensified across the globe (see Voelker et al.

Both events appear contemporaneous with the collapse of ancient civilizations in lowlatitude regions where roughly half of Earth’s population lives today. 1. INTRODUCTION Remarkable, well-dated evidence of high-magnitude, abrupt climate changes occurring during the last glacial period between ∼80 and 10 ka have been documented in Greenland ice cores and marine and terrestrial records in the Northern Hemisphere. These climate perturbations are known as the Dansgaard-Oeschger (D-O) warming and cooling cycles of 2–3 kyr duration.
