This short video describes how the compression of Antarctic snow into ice captures air from past atmospheres. It shows how ice cores are drilled from the Antarctic ice and prepared for shipment and subsequent analysis.

This short video describes the Hestia project - a software tool and data model that provide visualizations of localized CO2 emissions from residential, commercial, and vehicle levels, as well as day versus night comparisons, in the city of Indianapolis.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.

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.

In this short but effective demonstration/experiment, students investigate how thermal expansion of water might affect sea level.

This is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.

In this activity, students learn how carbon cycles through the Earth system by playing an online game.

This short video shows how different biomass feedstocks are processed and refined into sustainable biofuels via biochemical and thermochemical processes.

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 video segment from What's Up in the Environment shares how an entire home can be constructed using green energy sources (solar and geothermal energy). Video is narrated by young boy whose father is the chief engineer on the project.
