This is an interactive webtool that allows the user to choose a state or country and both assess how climate has changed over time and project what future changes are predicted to occur in a given area.

This interactive/applet allows the user to explore the potential increase in carbon emissions over the next 50 years, subject to modifications made by the user in various technologies that impact carbon output. Part of the Visualizing and Understanding the Science of Climate Change module.

In this activity, students compare carbon dioxide data from Mauna Loa Observatory, Barrow, Alaska, and the South Pole over the past 40 years. Students use the data to learn about what causes short-term and long-term changes in atmospheric carbon dioxide. This activity makes extensive use of Excel.
