Frequently Asked Questions
What percentage of Earth's water is freshwater available for human use?
About 2.5 percent of Earth's water is freshwater. Of this, about 69 percent is frozen in ice caps and glaciers. Of the remaining liquid freshwater, about 30 percent is groundwater. Only about 1 percent of all freshwater is available as surface water in rivers and lakes accessible to humans.
Why is groundwater important despite being invisible?
Groundwater stores about 30 times more freshwater than all surface water. It provides drinking water to about 2 billion people globally and is essential for agriculture. Unlike surface water, groundwater is protected from direct evaporation and pollution by overlying soil layers.
How does the water cycle interact with climate change?
Warmer global temperatures increase evaporation, potentially leading to more extreme rainfall events. Changes in evaporation patterns affect cloud formation, altering regional precipitation. Altered water cycle contributes to droughts in some regions and floods in others, affecting agriculture and water security.
