Understanding a Changing Planet
Earth’s climate has changed dramatically throughout history. Learn how solar activity, volcanic eruptions, greenhouse gases, ocean circulation, tectonic shifts, and other natural forces shaped ancient climates.
Ice Ages dramatically changed Earth’s geography, climate, wildlife, and ecosystems. Learn how massive glaciers carved continents, influenced evolution, shaped coastlines, and helped create the modern world we know today.
Paleoclimate science reveals how Earth’s climate has changed over thousands and millions of years. Learn how ice cores, fossils, tree rings, ocean sediments, and other natural archives help scientists reconstruct ancient climates and better understand the future of our planet.
