In this activity students research the inter-dependencies among plants and animals in an ecosystem and explore how climate change might affect those inter-dependencies and the ecosystem as a whole.

This graph, based on key ice core data sets and recent monitoring programs, shows the variations in concentration of carbon dioxide (CO2) in the atmosphere during the last 400,000 years.

This graphic depicts evidence for a human fingerprint on climate change based on multiple sets of independent observations. The graphic is available to study at three levels - basic, intermediate, and advanced understanding, with substantial support for students to investigate the evidence themselves and draw their own conclusions.

This video from NASA features scientists who describe the role of salt in the oceans and global oceanic circulation, especially the effect of salinity on the density of water and its global circulation, with reference to global climate change.

A short video on the causes of ocean acidification and its effects on marine ecosystems.

In this activity learners investigate the link between ocean temperatures and hurricane intensity, analyze instrumental and historical data, and explore possible future changes.

This interactive shows the impact of a changing climate on maple syrup sap production. Students can explore the changes in production under two different emissions scenarios.

This slideshow lays out a photo story with short descriptions of how city buildings all over the world are taking climate change and rising sea level seriously, designing structures that can react to unforeseen changes. As sea levels continue to rise, architects design ways to live with the rising water.

In this lab activity students generate their own biomass gases by heating wood pellets or wood splints in a test tube. They collect the resulting gases and use the gas to roast a marshmallow. Students also evaluate which biomass fuel is the best by their own criteria or by examining the volume of gas produced by each type of fuel.

A video from the Extreme Ice Survey in which Dr. Tad Pfeffer and photographer Jim Balog discuss the dynamics of the Columbia glacier's retreat in recent years through this time-lapse movie. Key point: glacier size is being reduced not just by glacial melting but due to a shift in glacial dynamics brought on by climate change.
