Global Climate Change: Resources for Environmental Literacy

Most scientists believe that Earth's climate is changing and in fact heating up. However, they don't all agree about the rate of change, the extent of the impact on our environment, or what can or should be done about it. This module is based on the premise that understanding what influences Earth's energy balance is necessary (though not sufficient) to make sound decisions about climate change. Among the key concepts: how weather and climate relate to transfer of energy in and out of Earth's atmosphere, and how human activities have changed Earth's land, oceans, and atmosphere.
