According to the Milankovitch theory, slow variations of the Earth's orbital parameters
change the amplitude of the seasonal cycle of insolation and are considered to be the main …

Correlation analysis is omnipresent in paleoclimatology, and often serves to support the
proposed climatic interpretation of a given proxy record. However, this analysis presents …

The astronomical theory of climate, in which the orbital variations of the Earth are taken to
drive the climate changes, explains many features of the paleoclimatic records …

The early Eocene climatic optimum was a period of major climatic and environmental
change that was caused by perturbations to the global carbon cycle. Recent work from …

Proxy records from across the Southern Hemisphere show significant local to regional scale
variability in climatic and environmental conditions during late Marine Isotope Stage 3 and …

A diverse array of fossil, geochemical and sedimentary data shows patterns of major change
at or near the Eocene–Oligocene boundary, indicating a period of fundamental climatic and …

Comparing simulations of key warm periods in Earth history with contemporaneous
geological proxy data is a useful approach for evaluating the ability of climate models to …

Comparisons of climate model hindcasts with independent proxy data are essential for
assessing model performance in non-analogue situations. However, standardized …

We undertake a study in two parts, where the overall aim is to quantitatively compare results
from climate proxy data with results from several climate model simulations from the …

Abstract The Last Glacial Maximum (LGM) is widely used to refer to the episode when global
ice volume last reached its maximum and associated sea levels were at their lowest …
