    This book groups together overviews and original research papers dealing with South American climate variability from the Last Glacial Maximum to the Holocene. The contributions deal with tropical, temperate and high latitudes climate variability in South America and in surrounding regions (including Pacific and Atlantic Oceans and Antarctica).

    A passive mineral dust aerosol model based on source strengths deduced from polar ice core dust concentrations is introduced into the Canadian Centre for Climate Modelling and Analysis (CCCma) second-generation atmospheric general circulation model (GCMII) and used to compare features of the fine particle mineral dust aerosol in a last glacial maximum (LGM) simulation to those of a. Based on various geological records of high-resolutions, this project aims at addressing the climate and environmental histories in China since the Last Glacial Maximum (LGM) and human impacts on the Holocene environmental changes. Significant progresses have been obtained with regards to the impacts of past temperature changes to Asian monsoon and to the arid/semi-arid ecosystems in China.

The Holocene glacial retreat is a geographical phenomenon that involved the global deglaciation of glaciers that previously had advanced during the Last Glacial sheet retreat initiated ca. 19, years ago and accelerated after ca.

15, years ago. The Holocene, starting with abrupt warm years ago, resulted in rapid melting of the remaining ice sheets of North America. The glacial maximum represents a period with very thick ice.

In the reconstruction of the last glacial cycle made for the Holocene and Last Glacial Maximum book safety assessment, the largest ice thickness over the Forsmark site is approximately 2, m. Ice-sheet simulations (SKB, a) indicate an ice surface gradient of approximately m per kilometer over Forsmark.

The Holocene (/ ˈ h ɒ l. ə ˌ s iː n, ˈ h ɒ l. oʊ- ˈ h oʊ. l ə- ˈ h oʊ. l oʊ-/ HOL-ə-seen, HOL-oh- HOH-lə- HOH-loh-) is the current geological began approximat cal years before present, after the last glacial period, which concluded with the Holocene glacial retreat.

The Holocene and the preceding Pleistocene together form the Quaternary period.

Here we provide a new global dust flux data set for Holocene and Last Glacial Maximum (LGM) conditions based on observational data. This book presents the results of a sequence of paleoclimatic modeling experiments and compares them with paleoenvironmental data.

We used the modeling experiments to illustrate how slowly changing external and internal boundary conditions have induced major changes in global climates since the last glacial maximum. In this paper, we describe the sensitivity of CCSM3 to the glacial forcings of the Last Glacial Maximum and the interglacial forcings of the mid-Holocene.

The forcings changed for the LGM are reduced atmospheric greenhouse gases, a 2–3-km ice sheet over North America and northern Europe, lowered sea level resulting in new land areas, and.

During the deglaciation that began in the Last Glacial Maximum and later in the Holocene, the main external climate drivers were the modulation of the orbital parameters of the Earth, change in the solar irradiance, volcanic activity, change in the properties of land cover (see Chap.

25), and the concentration of greenhouse gases in the. Palaeovegetation of China: a pollen data‐based synthesis for the mid‐Holocene and last glacial maximum. Corresponding Author.

This is a constraint on the overall terrestrial uptake during the last glacial‐interglacial transition and the early Holocene and, therefore, on the magnitude of calcite compensation.

The LGM, approximately 21 yr ago, is a glacial period with large changes in the greenhouse gases, sea level, and ice sheets. The mid-Holocene, approximately yr ago, occurred during the current interglacial with primary changes in the seasonal solar irradiance.

The climate of the Holocene. The last glacial maximum (Ice Age) ended about 15 thousand years ago. The most recent glacial retreat is still going on.

We call the current period of glacial retreat the Holocene epoch and it continues until present. This page discusses the climate changes within the Holocene Epoch or the current interglacial. sea level; ice volumes; Last Glacial Maximum; Holocene; The understanding of the change in ocean volume during glacial cycles is pertinent to several areas of earth science: for estimating the volume of ice and its geographic distribution through time (); for calibrating isotopic proxy indicators of ocean volume change (2, 3); for estimating vertical rates of land movement from.

This paper addresses the question of the magnitude and time dependence of the globally averaged (eustatic) rise of sea level that occurred subsequent to the time of Last Glacial Maximum (LGM) at approximat calendar years before present.
