John Imbrie (paleoclimatologist)

John Imbrie was a distinguished paleoclimatologist who studied Earth's past climates. He primarily investigated ice cores, sediment layers, and other natural records to understand how the climate has changed over thousands to millions of years. His research helped uncover the natural cycles of ice ages driven by variations in Earth's orbit and other factors. Imbrie’s work was foundational in linking astronomy to climate change, providing insight into how Earth's climate system operates and offering context for current climate shifts. His contributions significantly advanced our understanding of long-term climate patterns and the forces shaping Earth's environmental history.
