This set of activities is about carbon sources, sinks, and fluxes among them - both with and without anthropogenic components.

In this activity, students use the absorption spectra of greenhouse gases to explore the nature of the greenhouse effect.

This activity utilizes a PhET greenhouse gas simulation to explore the interaction of different atmospheric gases with different types of radiation.

Using real data from NASA's GRACE satellites, students will track water mass changes in the U.S., data that measures changes in ice, surface and especially groundwater. The background information includes an animated video about where water exists and how it moves around Earth, as well as short video clips to introduce the GRACE mission and explain how satellites collect data. Students will estimate water resources using heat-map data, create a line graph for a specific location, then assess trends and discuss implications.

This activity illustrates the importance of water resources and how changes in climate are closely linked to changes in water resources. The activity could fit into many parts of a science curriculum, for example a unit on water could be connected to climate change.

This activity supports educators in the use of the activities that accompany the GLOBE Program's Earth System Poster 'Exploring Connections in Year 2007'. Students identify global patterns and connections in environmental data that include soil moisture, insolation, surface temperature, cloud fraction, precipitation, world topography/bathymetry, aerosol optical thickness, and biosphere (from different times of the year) with the goal of recognizing patterns and trends in global data sets.

This lesson explores the chemistry of some of the greenhouse gases that affect Earth's climate. Third in a series of 9 lessons from an online module entitled 'Visualizing and Understanding the Science of Climate Change'.

This is the seventh of nine lessons in the 'Visualizing and Understanding the Science of Climate Change' website. This lesson addresses climate feedback loops and how these loops help drive and regulate Earth's unique climate system.

Students gain experience using a spreadsheet and working with others to decide how to conduct their model 'experiments' with the NASA GEEBITT (Global Equilibrium Energy Balance Interactive Tinker Toy). This activity helps students become more familiar with the physical processes that made Earth's early climate so different from that of today. Students also acquire first-hand experience with a limitation in modeling, specifically, parameterization of critical processes.

In this activity, students work with climate data from the tropical Pacific Ocean to understand how sea-surface temperature and atmospheric pressure affect precipitation in the tropical Pacific in a case study format.

This lesson covers different aspects of the major greenhouse gases - water vapor, carbon dioxide, methane, nitrous oxides and CFCs - including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases. This is lesson six in a nine-lesson module about climate change.
