This high-resolution narrated video shows levels and movements of CO2 globally through the course of a year.

This video features research conducted at University of Colorado's Institute of Arctic and Alpine Research, which studies isotopes of hydrogen trapped in ice cores to understand climate changes in the past.

This image depicts a representative subset of the atmospheric processes related to aerosol lifecycles, cloud lifecycles, and aerosol-cloud-precipitation interactions that must be understood to improve future climate predictions.

For this lesson, the guiding Concept Question is: What is climate change and how does climate relate to greenhouse gas concentrations over time? This activity is the second lesson in a nine-lesson module 'Visualizing and Understanding the Science of Climate Change' produced by the International Year of Chemistry project (2011).

Climate Change 2013: The Physical Science Basis

On September 27, 2013, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) presented its report to member governments for approval and acceptance. The report is the first of four that will make up the IPCC's 5th Assessment.

Carbon Dioxide Information Analysis Center (CDIAC)

The CDIAC is the primary global-change data and information analysis center of the U.S. Department of Energy (DOE). It contains information on concentrations of carbon dioxide and other radioactively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.

In this hands-on activity, participants learn the characteristics of the five layers of the atmosphere and make illustrations to represent them. They roll the drawings and place them in clear plastic cylinders, and then stack the cylinders to make a model column of the atmosphere.

This video illustrates how atmospheric particles, or aerosols (such as black carbon, sulfates, dust, fog), can affect the energy balance of Earth regionally, and the implications for surface temperature warming and cooling.

This climate change interactive modeling simulation simulates the interactions among different sets of variables related to climate change. This is a facilitated guided-inquiry exercise.
