In North America and Adjacent Oceans During the Last Deglaciation, edited 273 The last déglaciation in Antarctica covering the last climatic transition (from ~ 15 to 10 kyr B.P.) which corresponds to the depths from 265 to 355 m. Due to higher accumulation, the same time interval corresponds to greater depths at Dome C (from 365 to 500 m) Here we use a network of proxy temperature records that provide broad spatial coverage to show that global temperature closely tracked the increase in CO 2 concentration over the last deglaciation, and that variations in the Atlantic meridional overturning circulation (AMOC) caused a seesawing of heat between the hemispheres, supporting an The last deglaciation in Antarctica: Further evidence of a Younger Dryas type climatic event.- Possible ice-core evidence for a fresh melt water cap over the Atlantic ocean in the early Holocene.- Climatic changes in Northwest Africa during the last deglaciation (16 7 ka BP).- Although the general patterns of deglacial climate change are relatively well constrained, how, and to what magnitude, large parts of the Southern Hemisphere responded to deglacial forcings remains unknown, particularly for the early part of the last deglaciation. On the stability of the Atlantic meridional overturning circulation during the last deglaciation Wei Liu Zhengyu Liu Jun Cheng Haibo Hu Received: 4 October 2013/Accepted: 17 April 2014 Springer-Verlag Berlin Heidelberg 2014 Abstract Using a generalized stability indicator L,we explore the stability of the Atlantic meridional overturning This was at the last vein trench about 1,600 metres east of the adit portal.

During the late Pleistocene epoch, ice sheets advanced and retreated in tandem with changing atmospheric carbon dioxide levels. The last deglaciation period ( 18 10 kyr BP) presents a transition from the last glacial stage to warm interglacial, accompanied an increase in global temperature, a rising sea-level, and melting ice volume. During the last deglaciation, the atmospheric CO 2 increased rapidly from 180 to 265 ppm. This AMOC over-stabilization bias needs to be improved in these CGCMs to allow for a credible projection of AMOC evolution in the future.

We review available chronologies that constrain the timing of glacier fluctuations during the last deglaciation in Alaska. We address three questions relating to the last glacial termination: (i) How did the timing of glacier recession relate to buildup of global CO 2, such as during the onset of CO 2 For example, during the last deglaciation around 14,000 years ago, rapid melting of ice sheets during Meltwater Pulse 1A produced rates of sea level rise in excess of 40 mm a 1 [35,36]. However, the world was then emerging from an ice age, and many ice sheets contained unstable marine components that have now largely disappeared.

Hodell, Triple oxygen and hydrogen isotopes of gypsum hydration water for quantitative paleo-humidity reconstruction, Earth and Planetary Science Letters, 2018, 481, 177CrossRef Here we present two new boron isotope records from the subtropical subpolar transition zone of the Southwest Pacific that span the last 20 kyr, as well as new radiocarbon data from the same cores. The new data suggest this region was a source of carbon to the atmosphere rather than a transient climate evolution of last deglaciation in light of updated or new proxy data reconstructions during the last decade, with the focus on the deglacial history of polar temperatures and its potential drivers, such as insolation, CO 2, ice sheet and ocean circulation. Comparison of the climate records from these cores suggests that, near the beginning of the last deglaciation, warming in Antarctica began approximately 3000 The Scandinavian Ice Sheet (SIS) was an important component of the global ice sheet system during the last glaciation, but the timing of its growth to or retreat from its maximum extent remains poorly known. We used 115 cosmogenic beryllium-10 ages and 70 radiocarbon ages to constrain the timing of three substantial ice-margin The last deglaciation (ca. 19 to 11 thousand years before present (kaBP), where present is defined as 1950) is the most recent example of a major naturally forced global climate change. Previous studies confirm opposing climate trends on millennial timescales between the northern and southern mid to high-latitudes during this interval (e.g Request PDF | Possible ENSO signals prior to the Last Glacial Maximum, during the last deglaciation and the early Holocene, from New Zealand | Annually
