How Do We Know Earth’s Past Climate? (Paleoclimates Part 1)

In this episode of Forecasting with Faye, I wanted to take a step back from day-to-day weather and look at the bigger picture: climate.
What actually is the difference between weather and climate? And how on Earth do we know what the climate was like thousands — or even millions — of years ago, long before we had any instruments?
In Part 1 of this series, I introduce paleoclimates (Earth’s ancient climates) and talk through the main reasons climate changes over time, from shifting continents to volcanic eruptions and even subtle changes in Earth’s orbit.
I also walk through how scientists piece together the past using natural clues like tree rings, ice cores, and sediment layers, and how these “proxies” allow us to reconstruct climates from deep time.
