Water Resources and Climate Change

Alan McDonald from the British Geological Survey discusses global water distribution, emphasizing the importance of groundwater. He explains the water cycle, highlighting the different time scales water spends in various parts of the cycle. The video also covers hydrology, the necessity of water storage, and the role of groundwater in addressing water scarcity. McDonald concludes with the challenges of predicting climate change impacts on water availability and the need for climate-resilient water sources.

What percentage of the world's freshwater is stored in glaciers?

• 30%

• 69%

• 1%

• 50%

Which component of the water cycle was first conceptualized by King Solomon?

• Evaporation
