This data viewing tool from NOAA is highly engaging and offers nearly instant access to dozens of datasets about Earth. Users select from atmosphere, ocean, land, cryosphere, and climate, and drill down from there into more detailed categories.

This interactive visualization provides a clear, well-documented snapshot of current and projected values of several climate variables for local areas in California. The climate variables include observed and projected temperatures, projected snowpack, areas vulnerable to flooding due to sea level rise, and projected increase in wildfires. The projected values come from expert sources and well-established climate models.

An interactive simulation of Earth's seasonal dynamics that includes the axial tilt and other aspects of Earth's annual cycle.

This is part of a larger lab from the University of Nebraska at Lincoln:

Global Forest Watch is an interactive, online forest monitoring and alert system that provides users globally with the information they need to better manage and conserve forest landscapes.

This interactive map allows students to experiment with decadal average temperature projections. Overall temperatures are expected to rise throughout the century and this tool demonstrates those projected measurements.

This clickable visualization demonstrates the catastrophic effect that follows the removal of a key producer or consumer in the Arctic food chain.

This simulation allows students to explore the change in sea surface pH levels with increasing CO2 levels.

This interactive contains four animated slides that introduce the greenhouse effect. An additional animation offers to 'explore more'.

This interactive exposes students to Earth's atmospheric gases of oxygen, carbon dioxide, and ozone. As the user manipulates the interactive to increase or decrease the concentration of each gas, explanations and images are provided that explain and visualize what the Earth would be like in each scenario.

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.
