Late glacial stage and holocene tropical ice core records from huascaran, peru.
Lonnie G. Thompson,Ellen Mosley-Thompson,Mary E. Davis,P.-N. Lin,Keith Henderson,Jihong Cole-Dai,J. F. Bolzan,Kam-biu Liu +7 more
TL;DR: Two ice cores from the col of Huascar�n in the north-central Andes of Peru contain a paleoclimatic history extending well into the Wisconsinan (W�rm) Glacial Stage and include evidence of the Younger Dryas cool phase, implying that a strong warming has dominated the last two centuries.
Journal ArticleDOI
Possible role of climate in the collapse of Classic Maya civilization
TL;DR: This paper used a 4.9m sediment core from Lake Chichancanab, Mexico, to reconstruct a continuous record of Holocene climate change for the central Yucatan peninsula.
Journal ArticleDOI
A study of the origin of central Brazilian forests by the analysis of plant species distribution patterns
TL;DR: The floristic nature of central Brazilian forests, as well as their links to other main forest formations of eastern tropical South America, is assessed by means of multivariate analyses of 106 existing florist checklists and by the analysis of a series of dot-maps showing the distribution of 55 woody species.

Late Quaternary Environmental and Climatic Changes in Central Brazil
TL;DR: In this paper, a study of modern vegetation and pollen distribution, taking into account present-day climatic parameters, has been carried out for reconstructing climate changes dating back to 30,000 B.P. documented in a pollen record from central Brazil.

Records of Late Pleistocene}Holocene climatic change in Mexico * a review
TL;DR: A review of palaeoclimatic records from Mexico which have a reasonable chronological framework and are readily accessible can be found in this article, where the available data indicate that over the Late Pleistocene and Holocene there have been significant climatic changes in Mexico, although smaller in magnitude than in other parts of the northern hemisphere tropics and subtropics.

Milankovitch and Climate
TL;DR: Adem et al. as discussed by the authors simulate the equilibrium climate at five different stages of the last deglaciation, in order to assess the respective role of different forcings: insolation, ice boundaries and sea surface temperature.

The Influence of Changing Orbital Parameters and Surface Boundary Conditions on Climate Simulations for the Past 18 000 Years
TL;DR: The authors used the Community Climate Model (CCM) of the National Center for Atmospheric Research (NCAR) to estimate the magnitude, timing and pattern of the climatic response to prescribed changes of orbital parameters (date of perihelion, axial tilt, eccentricity) and glacial-age lower boundary conditions (ice sheets, land albedo, sea ice and sea surface temperature).

Milankovitch forcing of fluctuations in the level of tropical lakes from 18 to 0 kyr BP
TL;DR: In this paper, an atmospheric general-circulation model has been used to simulate the climates of January and July at 3,000-yr intervals, from 15 kyr BP onwards, the model simulates a strengthened monsoon circulation and increased precipitation in the Northern Hemisphere tropics.
