This is an interactive map of California and the Sierra Nevada mountains, showing projected variations in water stored in snowpack, from 1950 to 2090, assuming low or high emission scenarios over that period of time. Interactive can be adjusted to show different months of the year and various climate models, graphed by site.

This poster, viewable online, highlights some of the impacts of a global-average temperature rise of 2 degrees C above the pre-industrial age climate.

This video documents the impact of the 2011 drought on the water supply of two Texas towns. It discusses how the higher temperatures have increased the evaporation from open reservoirs, resulting in a drop in their water levels. The use of water in fighting wildfires has also contributed to this drawdown. While some jurisdictions have been able to develop pipelines to other sources, others have had to resort to trucking water in.

This video examines how scientists learn about the effects of climate change on the water cycle and what those effects might mean for our planet.

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 interactive map from National Geographic shows selected geographic locations for a number of impacts of global warming (on freshwater resources, food and forests, ecosystems, etc). Impact overview is summarized for each highlighted impact.

This activity addresses climate change impacts that affect all states that are part of the Colorado River Basin and are dependent on its water. Students examine available data, the possible consequences of changes to various user groups, and suggest solutions to adapt to these changes.

This interactive world map shows the impact of a global temperature rise of 4 degrees Celsius on a variety of factors including agriculture, marine life, fires, weather patterns, and health. Hot Spots can be clicked on to get more specific information about the problems in different regions.

This video features interviews with native people living on atoll islands in Micronesia, so viewers are able to understand the real, current threats that these people are facing due to climate change.

This visualization, from the US Geological Survey, provides a simple schematic of the various pathways that water can take as it cycles through ocean, lakes, atmosphere, surface and ground.
