Last week, we reported on how scientists have been using 14 years of satellite data to study changes in Earth’s freshwater supplies. Information from the Gravity Recovery and Climate Experiment (GRACE), which began in 2002, revealed that changes in Earth’s water supplies are impacted by climate change, human water management, and natural cycles.
Now, today’s Video of the Day comes from the NASA Goddard Space Flight Center and takes a closer look at regional changes in freshwater storage. For example, melting glaciers have led to decreased storage in Greenland, while severe drought in the southwestern United States caused heightened depletion of freshwater sources.
