This Motions of the Sun Lab is an interactive applet from the University of Nebraska-Lincoln Astronomy Applet project.

This static graph of changes in CO2 concentrations is going back 400,000 years, showing the dramatic spike in recent years.

This introductory video addresses key points as well as pros and cons of oil as an energy source for transportation.

In this activity, students use Google Earth and information from several websites to investigate some of the consequences of climate change in polar regions, including the shrinking of the ice cap at the North Pole, disintegration of ice shelves, melting of Greenland, opening of shipping routes, effects on polar bears, and possible secondary effects on climate in other regions due to changes in ocean currents. Students learn to use satellite and aerial imagery, maps, graphs, and statistics to interpret trends accompanying changes in the Earth system.

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

In this video, a spokesperson for the National Climactic Data Center describes the methods of using satellites (originally designed for observing changes in the weather) to study changes in climate from decade to decade. The video clearly illustrates the value of satellite data and begins to address connections between weather and climate.

This gallery of ten temperature graphs shows global temperatures on different timescales from decades (recently measured temperatures) to centuries (reconstructed) to millions of years (modeled from ice cores).

Animations of CO2 concentration in the free troposphere, as simulated by NOAA's ESRL CarbonTracker.

This hands-on activity introduces students to the process of fermenting different carbohydrate sources into ethanol. Teachers demonstrate yeasts' inability to metabolize certain food sources.

This poster, viewable online, highlights some of the impacts of a global-average temperature rise of 2 degrees C above the pre-industrial age climate.
