These slide sets (one for the Eastern US and one for the Western US) describe how citizen observations can document the impact of climate change on plants and animals. They introduce the topic of phenology and data collection, the impact of climate change on phenology, and how individuals can become citizen scientists.

A collection of repeat photography of glaciers from the National Snow and Ice Data Center (NSIDC). The photos are taken years apart at or near the same location, and at the same time of year. These images illustrate how dramatically glacier positions can change even over a relatively short period in geological time: 60 to 100 years. Background essay and discussion questions are included.

This is a simulation that illustrates how temperature will be affected by global CO2 emission trajectories. It addresses the issue that even if global emissions begin to decrease, the atmospheric concentration of CO2 will continue to increase, resulting in increased global temperatures.

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.

One of a suite of online climate interactive simulations, this Greenhouse Gas Simulator uses the bathtub model to demonstrate how atmospheric concentrations of CO2 will continue to rise unless they are lowered to match the amount of CO2 that can be removed through natural processes.

Two simple experiments/demonstrations show the role of plants in mitigating the acidification caused when CO2 is dissolved in water.

This is an animated interactive simulation that illustrates differential solar heating on a surface in full sunlight versus in the shade.

This visualization shows the molecular interaction of infrared radiation with various gases in the atmosphere. Focus is on the interaction with C02 molecules and resultant warming of the troposphere.

This interactive visualization adapted from NASA and the U.S. Geological Survey illustrates the concept of albedo, which is the measure of how much solar radiation is reflected from Earth's surface.

This short investigation from Carbo Europe explores how temperature affects the solubility of carbon dioxide in water.
