Students explore the increase in atmospheric carbon dioxide over the past 40 years with an interactive online model. They use the model and observations to estimate present emission rates and emission growth rates. The model is then used to estimate future levels of carbon dioxide using different future emission scenarios. These different scenarios are then linked by students to climate model predictions also used by the Intergovernmental Panel on Climate Change.

This lesson explores the chemistry of some of the greenhouse gases that affect Earth's climate. Third in a series of 9 lessons from an online module entitled 'Visualizing and Understanding the Science of Climate Change'.

This series of two lessons uses cutting-edge scientific research on the effects of climate change on communities in the intertidal. Through a combination of a dynamic presentation and several videos, students are introduced to the effects of climate change on the ocean (ocean acidification and temperature increase) and what is known about how ocean organisms are affected. Then students read and interpret graphs and construct a scientific explanation based on data from this research.
