This site provides a useful set of graphical representations of mean temperature change in different land/ocean surfaces over the past 120+ years.

This tool provides a summary of daily records broken in several weather parameters (temperature, precipitation, snow fall, snow depth), over various time intervals, in the US and globally.

This is a full color, worldwide, animated weather map using GIS interface showing current and projected wind and other weather conditions for any location in the world. Data can be viewed at different spatial scales.

In this activity, students learn about the scientific evidence supporting climate change, use this information to evaluate and improve conclusions some people might draw about climate change, and participate in a role-play to negotiate solutions to climate change.

In this short activity, students create a timeline of climate science over the past 200 years and gather information from a U.S. Forest Service video about mitigation and adaptation strategies undertaken by the Service to address climate change in national forests.

This set of interactive data visualizations show the weather and climate events that have had the greatest economic impact on the US from 1980 to present (updated annually).

In this activity, students calculate electricity use by state and determine, using Google Earth, how much land would be required to replace all sources of electricity with solar panels.

In this activity, students use the absorption spectra of greenhouse gases to explore the nature of the greenhouse effect.

This activity uses two interactive simulations to illustrate climate change, 1) at the micro/molecular level - modeling the impact of increasing concentrations of greenhouse gases in the atmosphere on surface temperature and 2) at the macro level - modeling changes in glacier thickness and flow as a result of rising surface temperature.

In this activity, students are guided through graphs of surface air temperature anomaly data and Vostok ice core data to illustrate how scientists use these data to develop the basis for modeling how climate is likely to change in the future.
