Webb31 jan. 2024 · Paleoclimatology is the study of Earth's climate during the entire history of the Earth. Paleoclimate research uses geologic and biologic evidence ( climate proxies) preserved in sediments, rocks, tree rings, corals, ice sheets and other climate archives to reconstruct past climate in terrestrial and aquatic environments around the world. WebbFirst, the overwhelming majority of geologic history occurred long before there were any human witnesses. Second, much of the evidence for the older events is highly fragmented. By studying rocks, fossils, and other geologic features, however, scientists can still reconstruct a great deal of what the ancient Earth might have looked like. The geological history of Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy).
