Geological and solar climates : Their causes and variations

This scholarly treatise opens a careful inquiry into why the Earth’s climate has swung between extremes over deep time. Drawing on the latest observations of glacial deposits and the emerging insights of solar physics, the author sets out to bridge geology and astronomy in search of a unified explanation for ancient ice ages and the broader patterns of planetary warmth and chill.

Through a blend of field evidence, mathematical estimates of Earth’s internal heat, and an examination of subtle astronomical cycles, the work builds a picture of climate as a dynamic system shaped by both terrestrial and celestial forces. Listeners will hear a thoughtful discussion of the Quaternary ice age, early Paleozoic glaciations, and the role of atmospheric composition, all presented in the measured style of a late‑19th‑century scientific argument.
