Where has all the groundwater gone, long time passing? (My apologies to Pete Seeger and Joe Hickerson.)
It’s gone into the sea.
Scientists in the Netherlands have made the shocking discovery that much of the water pumped out of the ground evaporates and ends up in the oceans. Amazingly, this raises the sea level by 0.8 millimeters per year. That doesn’t sound like a lot, but to put it in perspective, that’s roughly the same amount of sea level rise caused by melting glaciers and icecaps outside of Greenland and Antarctica and 25% of the total sea level rise per year!
