We live at the bottom of a thin layer of gases surrounding the earth called the atmosphere, which is divided into smaller spherical layers. In the troposphere, the layer closest to earth, about 75-80% of the earths air mass is found here.. Ozone Depletion(Chapter 25). Ozone Properties.

Climate change science needs to be better understood by society to enable the best decisions for responsible action. The PowerPoint slides in this file contain information about the science of climate change. Three other collections provide information about the effects of climate change and the effects of climate change on health. For the slides on causes and effects, please visit: .
