This interactive graphic outlines the carbon cycle, with clickable text boxes that explain and elaborate each component.

A simplified representation of the terrestrial carbon cycle side by side with the ocean carbon cycle. Fluxes and reservoirs expressed in gigatons are included.

Interactive visualization that provides a basic overview of the Earth's carbon reservoirs and amount of carbon stored in each, CO2 transport among atmosphere, hydrosphere, geosphere, and biosphere, and a graph comparing global temp (deg C) and atmospheric CO2 levels (ppm) over the past 1000 years.

This is a photo essay linked to a New York Times story about climate-related stressors on forests -- including mountain pine beetles, forest fires, forest clearance, and ice storms -- and the importance of protecting forests as an important carbon sink.

In this 3-part lab activity, students investigate how carbon moves through the global carbon cycle and study the effects of specific feedback loops on the carbon cycle.

This narrated slide presentation shows the carbon cycle, looking at various parts of this biogeochemical sequence by examining carbon reservoirs and how carbon is exchanged among them and the atmosphere.

In this activity, students investigate soil erosion and how a changing climate could influence erosion rates in agricultural areas. This activity is part of a larger InTeGrate module called Growing Concern.

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

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

This interactive shows the different components of the ocean biological pump, i.e., how carbon in the form of either plankton or particles moves into the ocean's depths. It illustrates the situation at the surface, 0-100 meters, 100-500 meters, and below 500 meters.
