Values for the precession and obliquity of the earth 9000 years ago indicate that the global average solar radiation for July 9000 years ago was 7 percent greater than at present. When the estimated solar radiation values are used in a low-resulation climate model, the model simulates an intensified continent-scale monsoon circulation. This result agrees with paleoclimatic evidence from Africa, Arabia, and India that monsoon rains were stronger between 10,000 and 5000 years ago than they are… 
The Sensitivity of Monsoon Climates to Orbital Parameter Changes for 9 000 Years BP : Experiments with the NCAR General Circulation Model
The July and January climates of 9 000 years ago are simulated with a high resolution general circulation model. The incoming solar radiation is specified from the orbital parameters for 9 000 years
Dynamics of the West African Monsoon under Mid-Holocene Precessional Forcing: Regional Climate Model Simulations
Abstract The African Humid Period (AHP), about 14 800 yr ago [14.8–5.5 ka (ka ≡ 1000 yr ago)], was a time of increased humidity over Africa. Paleoclimate evidence suggests that the West African
Indian summer monsoon during the last two millennia
The monsoon is a large‐scale feature of the tropical atmospheric circulation, affecting people and economies in the world's most densely populated regions. Future trends due to natural variability
Milankovitch forcing of fluctuations in the level of tropical lakes from 18 to 0 kyr BP
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
Southward Shift of the Pacific ITCZ During the Holocene
The Holocene (0–11.7 ka BP) appears warm and stable in ice core and global temperature reconstructions as well as in transient climate simulations. This seeming quiescence of Earth's climate belies

New dates for late Quaternary glaciations in the Himalayas show that, during the last glacial cycle, glaciations were not synchronous throughout the region. Rather, in some areas glaciers reached
African monsoons, an immediate climate response to orbital insolation
The Croll–Milankovitch astronomical theory of climate1–3 has received strong support from the evidence of a linear climatic forcing by obliquity and precession, although nonlinearity had to be
Orbital history and seasonality of regional precipitation
The Arizona monsoon, a major source of precipitation in the Southwest, shares many features with the monsoons of other continents. Computer modeling and fossil data indicate maximum extent of the

Modeling the Climatic Response to Orbital Variations
TLDR
This article summarizes how the theory has evolved since the pioneer studies of James Croll and Milutin Milankovitch, reviews recent evidence that supports the theory, and argues that a major opportunity is at hand to investigate the physical mechanisms by which the climate system responds to orbital forcing.

Oceanic mechanisms for amplification of the 23,000-year ice-volume cycle.
TLDR
Spectral data indicate that the oceanic moisture and sea-level feedbacks, in part controlled by glacial melt products, amplify Milankovitch (insolation) forcing of the volumetrically dominant mid-latitude ice sheets at the 23,000-year precessional cycle.
Variations in the Earth's Orbit: Pacemaker of the Ice Ages
TLDR
It is concluded that changes in the earth's orbital geometry are the fundamental cause of the succession of Quaternary ice ages and a model of future climate based on the observed orbital-climate relationships, but ignoring anthropogenic effects, predicts that the long-term trend over the next sevem thousand years is toward extensive Northern Hemisphere glaciation.
