This video describes how field research -- in this case, making water measurements in rugged mountain locations -- helps us to understand the complex relationships among changing climate, populations, and water usage.

This video features Katharine Hayhoe presenting a lively discussion of impacts that the Midwestern US is experiencing due to climate change. It steps through evidence for how climate change is affecting agriculture, tourism, drought and flood, water cycles and freshwater availability, the spread of invasive species and disease, as well as other topics.

This classroom demonstration illustrates the amount of water stored in various parts of the Earth system in a straightforward manner. Students estimate the proportions of water in the oceans, icecaps and glaciers, groundwater, freshwater lakes, inland seas, soil moisture, atmosphere, and rivers. Then they fill beakers with the actual proportion and discuss what elements of the activity were surprising to them. Information on flash floods and flood preparedness and safety are included.
