What is paleoclimatology?
Quick Answer
Paleoclimatology is the study of Earthβs past climates using evidence from ice cores, tree rings, sediments, corals, and other natural archives. It helps scientists understand climate change long before modern thermometers existed.
The Full Story
Because direct weather records are short, scientists use proxies to reconstruct ancient climates. Ice cores from Greenland and Antarctica preserve trapped air bubbles that reveal past greenhouse gas concentrations, while tree rings can show years of drought or abundant rainfall. Sediment layers, fossils, and cave deposits also record changes in temperature and precipitation. Paleoclimatology provides context for modern climate change by showing how climate has varied over thousands to millions of years.
