Abrupt Climate Change. Mechanisms, Patterns, and Impacts by Harunur Rashid, Leonid Polyak, Ellen Mosley-Thompson

By Harunur Rashid, Leonid Polyak, Ellen Mosley-Thompson

Published by means of the yank Geophysical Union as a part of the Geophysical Monograph Series.Abrupt weather switch: Mechanisms, styles, and Impacts brings jointly a various crew of paleoproxy files corresponding to ice cores, marine sediments, terrestrial (lakes and speleothems) information, and paired ocean-atmosphere weather versions to record fresh advances in realizing the mechanisms of abrupt weather alterations. because the discovery of the Dansgaard-Oeschger occasions in Greenland ice cores and the next 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...

Environmental Stratified Flows (Topics in Environmental Fluid Mechanics)

The dynamics of flows in density-stratified fluids are an vital subject for clinical enquiry. Flows come up in lots of contexts, starting from commercial settings to the oceanic and atmospheric environments. either the sea and surroundings are characterised through the uncomplicated vertical density stratification, and this option can impact the dynamics on all scales starting from the micro-scale to the planetary scale.

Interhemispheric Water Exchange in the Atlantic Ocean

Contemporary effects from modeling and observational reviews reveal that the tropical Atlantic is a serious quarter for techniques that retain the meridional overturning movement, resembling cross-equatorial exchanges, and for sea floor temperature variability that affects on weather variability of the coupled tropical ocean/atmosphere method.

Shifting Baselines: The Past and the Future of Ocean Fisheries

Moving Baselines explores the real-world implications of a groundbreaking notion: we needs to comprehend the oceans of the earlier to guard the oceans of the long run. In 1995, acclaimed marine biologist Daniel Pauly coined the time period "shifting baselines" to explain a phenomenon of diminished expectancies, during which each one new release regards a gradually poorer flora and fauna as general.

Quasi-Geostrophic Theory of Oceans and Atmosphere: Topics in the Dynamics and Thermodynamics of the Fluid Earth

Large-scale winds and currents are inclined to stability Coriolis and strain gradient forces. The time evolution of those winds and currents is the topic of the quasi-geostrophic thought. bankruptcy 1 provides strategies and equations of classical inertial fluid mechanics. bankruptcy 2 bargains with the equations of thermodynamics that shut the governing equations of the fluids.

Several proxy records and two data-model comparison studies simulate Atlantic meridional overturning circulation during the last deglaciation and millennial-scale temperature oscillations during the last glacial cycle and thereby provide new perspectives on the mechanisms controlling abrupt climate changes. Two hypotheses are presented to explain deep Southern Ocean carbon storage, the rapid increase of the atmospheric carbon dioxide, and retreat of sea ice in the Antarctic Ocean during the last deglaciation.
