Humans are causing massive changes in the location of water around the world, NASA says

This article discusses the impact that humans are having on the planet’s water resources.

A 14-year NASA mission has confirmed that a massive redistribution of freshwater is occurring across Earth, with middle-latitude belts drying and the tropics and higher latitudes gaining water supplies.

The results, which are probably a combination of the effects of climate change, vast human withdrawals of groundwater and simple natural changes, could have profound consequences if they continue, pointing to a situation in which some highly populous regions could struggle to find enough water in the future.

“To me, the fact that we can see this very strong fingerprint of human activities on the global water redistribution, should be a cause for alarm,” said Jay Famiglietti, a researcher at NASA’s Jet Propulsion Laboratory and one of the authors of a study published in Nature in May 2018.
