ABOUT
Earth's Climate Trajectory

Recently, carbon dioxide levels on Earth passed the 400 ppm threshold for the first time in human history. How do we know this, and how does the present and future climate compare to what the Earth has experienced in the past? In this talk we’ll examine how Earth’s climate has changed since the time of the Dinosaurs (the Mesozoic Era) and what drove changes between warm and cold climate states. As we shall see, these ancient changes in climate hold valuable lessons for present and future climate change, offering a glimpse of what to expect in a warmer world.
