Reconstructing earth's atmospheric
WebbWe reconstructed the direction and/or intensity of Earth’s magnetic field recorded in 20 burnt destruction layers exposed at 17 archaeological sites and in two ceramic assemblages (SI Appendix, Tables S1–S6).From the destruction layers we sampled sun-dried mud bricks (SI Appendix, Fig. S1A), which had acquired thermoremanent … Webb"In developing Reconstructing Earth's Climate History, St John et al. say that they were driven by the philosophy that "addressing how we know is as important as addressing what we know about past climate".They have, without question, lived up to the billing. The book is composed of exercises based on authentic data, with well-constructed, full-color …

WebbAbstract. Understanding the evolution of, and the interactions between, ice sheets and the global climate over geological timescales is important for being able to project their future evolution. However, direct observational evidence of past CO2 concentrations, and the implied radiative forcing, only exists for the past 800 000 years. Records of benthic δ18O … WebbReconstructing historical atmospheric oxygen (O2) levels at finer temporal resolution is a top priority for exploring the evolution of life on Earth. This goal, however, is challenged by gaps in traditionally employed sediment-hosted geochemical proxy data. Here, we propose an independent strategy—machine learning with global mafic igneous geochemistry big …
