Freshwater is found in lakes, rivers, soil, snow, groundwater and ice, and is one of the most essential of Earth's resources, for drinking water and agriculture. However, the distribution of freshwater around the planet is changing.

Students observe images individually, looking for changes in surface air temperatures (using data displayed, unit of measure, range of values, etc.) and patterns noticeable within the map.
Review this mapped plot of the historic Ocean Chlorophyll Concentrations of key locations around the world for the period of 1998-2018. Also, consider using the Map Cube to help students with deeper dives into data analysis. Credit: NASA, NOAA
Introduction to the concept of albedo.
Students observe seasonal images of Monthly Normalized Difference Vegetation, looking for any changes in vegetation that are occurring throughout the year.
Students observe monthly images of changing vegetation patterns, looking for seasonal changes occurring throughout 2017.
Students observe images of daily average sea surface temperatures taken during 2017, as they analyze the plots for evidence of changes that are occurring throughout the year.
The Earth's system is characterized by the interaction of processes that take place on molecular (very small) and planetary (very large) spatial scales, as well as on short and long time scales. Scientific visualizations allow us to experience Earth processes at faster speeds, and on manageable smaller scales, facilitating data analysis and enhancing understanding. Explore the visualizations below to see the new benchmark map scientists can use to study the extent and speed of changes to the largest ice sheet in the world.
Observe the seasonal global images of the chlorophyll data from 2017 and put in chronological order.
