Deep Time, Deep Oceans: Discovering Earth’s Past Climate With Gerald Dickens
Nov 25, 2024
Gerald Dickens, a Professor of Geology and Mineralogy at Trinity College Dublin, shares his insights on Earth's historical climate through the lens of ancient oceans. He explains how sediment cores reveal vital data about past climate shifts, notably the Paleocene-Eocene Thermal Maximum. The conversation highlights the dynamics of carbon cycles, the implications of ocean pH drop, and how small temperature changes could trigger significant environmental disruptions. Join Gerald as he uncovers the intricate connections between our planet's geological past and future climate scenarios.
