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 PBS Learning Media activity addresses drought basics, including its causes and impacts and ways to assess it, by using media from NOAA and NASA. It defines the types of drought, the impacts, monitoring, and responses to drought. Use this resource to stimulate thinking and questions on the complexity of drought and to identify some variables used in defining drought.
