  • The Oldest Living Trees on Earth: Ancient Forests That Defy Time

    The Oldest Living Trees on Earth: Ancient Forests That Defy Time
    Feb 16 2026
    Some living organisms on Earth are older than entire civilizations. This episode explores the planet’s most ancient trees, from bristlecone pines to giant sequoias, and the science used to verify their extraordinary ages through dendrochronology.

    We examine the biological adaptations and environmental conditions that allow these organisms to survive for thousands of years, and why they serve as invaluable climate archives. The discussion also distinguishes between individual ancient trees and vast clonal colonies that can persist for tens of thousands of years—while addressing the modern threats that now endanger these living monuments.
