For millennia, humans have harnessed rivers, built dams, and dug wells to quench our growing civilization. Now, for the first time, we have a picture of what all those generations have wrought on our blue planet’s most defining resource.
Newly analyzed data from groundwater-detecting satellites “reveals a clear human fingerprint on the global water cycle,” according to a study out Wednesday in the journal Nature. It’s the kind of result that is equal parts terrifying and long-expected in its implications.
“We know for sure that some of these impacts are caused by climate change,” says lead author Matt Rodell, chief of the Hydrological Sciences Laboratory at NASA. “We are using huge parts of the [Earth’s] available water.”
The authors used the satellite data to construct a map of 34 rapidly changing regions around the world, painting a unified picture of current hot spots of water scarcity and excess. Nearly every activity that involves people requires water — rice farming, […]
