This series of visualizations show the annual Arctic sea ice minimum from 1979 to 2015. The decrease in Arctic sea ice over time is shown in an animation and a graph plotted simultaneously, but can be parsed so that the change in sea ice area can be shown without the graph.

Using US Drought Monitor data and its classification system, this interactive tool tracks drought in the continental US by county, from 2000 to the present.

This is a extensive collection of maps, data, and tools that students can use to research drought and its impacts on agriculture, wildfires, water supply, vegetation, soil moisture, temperature and precipitation.
