This simulation allows the user to project CO2 sources and sinks by adjusting the points on a graph and then running the simulation to see projections for the impact on atmospheric CO2 and global temperatures.

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

This video documents how scientists, using marine algae, can study climate change in the past to help understand potential effects of climate change in the future.
