Released by means of the yank Geophysical Union as a part of the Geophysical Monograph sequence, quantity 193.

Abrupt weather swap: Mechanisms, styles, and Impacts
brings jointly a various team of paleoproxy documents comparable to ice cores, marine sediments, terrestrial (lakes and speleothems) information, and matched ocean-atmosphere weather types to record contemporary advances in figuring out the mechanisms of abrupt weather adjustments. 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 hunt for those abrupt, millennial-scale occasions around the globe has intensified, and for that reason, the variety of paleoclimatic documents chronicling such occasions has elevated. the amount highlights contain discussions of documents of prior weather variability, meridional overturning circulate, land-ocean-atmosphere interactions, feedbacks within the weather procedure, and international temperature anomalies. Abrupt weather Change may be of curiosity to scholars, researchers, teachers, and coverage makers who're interested by abrupt weather switch and its power influence on society.

Flower, C. Williams, and H. W. Hill1 College of Marine Science, University of South Florida, St. Petersburg, Florida, USA D. W. Hastings Marine Science Discipline, Eckerd College, St. Petersburg, Florida, USA Meltwater input from the Laurentide Ice Sheet (LIS) has often been invoked as a cause of proximal sea surface temperature (SST) and salinity change in the North Atlantic and of regional to global climate change via its influence on the Atlantic meridional overturning circulation (AMOC). Here we review the evidence for meltwater inflow to the Gulf of Mexico and its reduction relative to the onset of the Younger Dryas, compare inferred meltwater inflow during marine isotope stage 3 (MIS 3), and thereby assess the role of LIS meltwater routing as a trigger of abrupt climate change.
