Comparison of Recently Proposed Causes of Climate Change
This paper compares the ideas contained in the main papers published on climate change since World War II to arrive at a suggested consensus of our present knowledge regarding climatic changes and their causes.

Complex lithofacies of Lucaogou Formation in Jimusar Sag promote strong heterogeneity of oil distribution in fine grained sedimentary rocks. It is of great significance to define the formation mechanism of fine-grained sedimentary rocks for favorable ...

Exo-Milankovitch Cycles. II. Climates of G-dwarf Planets in Dynamically Hot Systems [PDF]
Using an energy balance model with ice sheets, we examine the climate response of an Earth-like planet orbiting a G-dwarf star and experiencing large orbital and obliquity variations.

Milankovitch Period Uncertainties and Their Impact on Cyclostratigraphy [PDF]
Astronomically calibrated cyclostratigraphy relies on correct matching of observed sedimentary cycles to predicted astronomical drivers such as eccentricity, obliquity and climate-precession. However the periods of these astronomical cycles, in the past,

The shale of the upper Es4 formation (Es4u), deposited during the Eocene in the Boxing Subsag of the Dongying Sag, is a typical set of lime-rich lacustrine shale in a continental rift basin.

An orbital window into the ancient Sun's mass [PDF]
Models of the Sun's long-term evolution suggest that its luminosity was substantially reduced 2-4 billion years ago, which is inconsistent with substantial evidence for warm and wet conditions in the geological records of both ancient Earth and Mars ...

The Effect of Milankovitch Variations in Insolation on Equatorial Seasonality [PDF]
Although the sun crosses the equator 2 times per year at the equinoxes, at times in the past the equatorial insolation has had only one maximum and one minimum throughout the seasonal cycle because of Milankovitch orbital variations.

Solar Resonant Diffusion Waves as a Driver of Terrestrial Climate Change [PDF]
A theory is described based on resonant thermal diffusion waves in the sun that appears to explain many details of the paleotemperature record for the last 5.3 million years.

Climatic cyclicity at Site 806; the GRAPE record [PDF]
We used the continuous saturated bulk density records collected by the gamma-ray attenuation porosity evaluator (GRAPE) at Ocean Drilling Program Site 806 on the top of the Ontong Java Plateau to evaluate the continuity of the recovered cores and to ...

Milankovitch cycles and carboniferous climate
Cyclical Permo‐Carboniferous sea level fluctuations have long been linked to glacial‐interglacial fluctuations on Gondwanaland. Similar to the Pleistocene, such fluctuations may in turn have been driven by variations in orbital insolation forcing. Herein we report results from climate model simulations that examine the effect of Milankovitch insolation
