Climate and Time in Their Geological Relations: A Theory of Secular Changes of the Earth's Climate

"Climate and Time in Their Geological Relations" by James Croll is a scientific publication written in the late 19th century. The work explores the concept of secular changes in the Earth's climate, particularly as they relate to geological phenomena such as the glacial epochs and the distribution of flora and fauna across different climatic zones. Croll aims to substantiate his theories with a rigorous presentation of facts and established physical principles, sidestepping hypothetical scenarios. The opening of the volume presents a preface in which Croll outlines his aims and the foundation of his subsequent arguments. He stresses the significance of understanding the climate as a dynamic agency influencing geological formations rather than attributing changes solely to violent geological events. Croll argues that the changes in Earth's climate are primarily governed by astronomical causes and emphasizes the importance of ocean currents and their role in distributing heat across the globe. He indicates that the investigation into how these climatic agents, which have consistently influenced geological history, forms the basis of the work, setting the stage for an in-depth analysis of the interplay between climate and geological change throughout different epochs.
