Environmental Data Science, 2022 Abstract Reconstructing past climate events relies on the relevant proxies and how they are related. Depending only on such relationships, however, could not be robust because only few proxy observations are usually available at each age. A state-space model employs a prior to make the hidden past climate events correlated with one another so that ...

Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Geophysical Monograph Series, Page 417-434., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Principles and Methods to Construct Detailed Models of Composite Modern and Paleotemperature Fields
Brazilian Journal of Geophysics, 2023 The western Siberia's geotemperature field belongs to the category of composite fields, which is manifested by its significant changeability due to abrupt climatic changes in the late Quaternary. Deviation of geotemperature gradients reaches ±50%. The mathematical model of the geotemperature field has been constructed and on its base methods were ...

A Comparison of the Variability of a Climate Model with Paleotemperature Estimates from a Network of Tree-Ring Densities [PDF]
Journal of Climate, 2002 Validation of the decadal to centennial timescale variability of coupled climate models is limited by the scarcity of long observational records. Proxy indicators of climate, such as tree rings, ice cores, etc., can be utilized for this purpose. This study presents a quantitative comparison of the variability of the third version of the Hadley Centre ...

Resolution and Fidelity of Oxygen Isotopes as Paleotemperature Proxies in Bivalve Mollusk Shells: Models and Observations [PDF]
PALAIOS, 2003 Abstract Bivalve mollusks are biological chart recorders: their shells contain a record of environmental conditions in the form of geochemical variation. However, these records are often incomplete. Growth cessations and/or changing growth rates can reduce the range and resolution of the recorded environmental conditions.

Databases for sea surface paleotemperature based on geochemical proxies from marine sediments: implications for model-data comparisons [PDF]
Quaternaire, 2017 The Paleoclimate Model Intercomparison Project (PMIP) aims to simulate the response of Earth’s climate system to changes in different climate forcing factors, focusing on six key intervals of the geological past (the mid-Piacenzian Warm Period at ~3.3-3.0 Ma, the last interglacial period at ~127 ka, the last glacial maximum at ~21 ka, the mid-Holocene ...

A Physical Model for Accurate Paleotemperature Reconstruction From Fluid Inclusions in Halite
American Journal of ScienceFluid inclusions (FI) trapped in microscopic cavities in halite (NaCl) crystals from evaporitic sedimentary basins are remnants of hypersaline waterbodies. Halite FI provide valuable information on past climate conditions because the density of the enclosed brine can be used for quantitative reconstructions of waterbody temperature
