Chapter 18: Dynamics of Past and Present Climate Change

Climate Change (Past and Present)


The norm of our planet is climate change, and although global warming and the melting of Polar Ice Caps signify negative change, our planet is constantly altering. For example, the fossilized tree from The Royal Tyrell museum, seen in the picture above, proves that the world does not stand still and that minute-by-minute imperceptible changes to our landscape and structures are ongoing. Just as glaciers expand and break off, trees and soil are subject to erosion. Data obtained from fossils like the weathered tree are then combined and inspected to determine what the environment might have been billions of years ago. In fact, it is through data of this kind that knowledge of the Earth during the time of dinosaurs is obtained.
