C-Learn is a simplified version of the C-ROADS simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

This monthly bulletin and animation provides regular and reliable visualizations of world weather and climate events of the previous month using NOAA data. Archives are available from October 2011 to present.

In this short video segment Native Americans talk about climate change and how it impacts their lives as they experience unexpected changes in environmental conditions. They describe observed changes in seasonality, how these changes affect ecosystems and habitats, their respect for Mother Earth, and the participation of tribal colleges in climate change research projects.

This series of four animations shows how some of the key indicators of climate change (average global temperature, sea level, sea ice extent, carbon emissions) have changed in Earth's recent history.

This is a figure from the 2007 IPCC Assessment Report 4 on atmospheric concentrations of carbon dioxide, methane and nitrous oxide over the last 10,000 years (large panels) and since 1750 (inset panels).

This interactive lets students determine the extent of average temperature change both in their community and anywhere else in the world, relative to average temperatures for the three decades between 1951 and 1980.

This Flash-based simulation explores the relationship between carbon emissions and atmospheric carbon dioxide using two main displays: (1) graphs that show the level of human-generated CO2 emissions, CO2 removals, and the level of CO2 in the atmosphere, and (2) a bathtub animation that shows the same information as the graphs. The bathtub simulation illustrates the challenges of reducing greenhouse gas concentrations in the atmosphere.

This applet is an ocean acidification grapher that allows user to plot changes in atmospheric C02 against ocean pH, from 1988 to 2009, in the central North Pacific.

This video provides background information and teaching tips about the history and relevance of phenology and seasonal observations of plants and animals within the context of rural Wisconsin.

This animation depicts real-time wind speed and direction at selected heights above Earth's surface, ocean surface currents, and ocean surface temperatures and anomalies.
