Climate change endangers half the world’s groundwater supply

Climate change today will effect the water supply for hundreds—possibly thousands—of years. Humans exist on a short leash. A person can only last around three days without drinking water. Put that way, human life is absurdly fragile; plenty of other organisms can go far longer. Just think of your houseplant. To make matters more precarious, that essential substance is growing harder to come by. You’ve heard about this: climate change

Historic proposal to create a conservation bank of water in Lake Powell fed by reservoirs in Colorado, Utah, Wyoming and New Mexico would protect the withering Powell and requires approval of eight states and the federal government

Nearly two decades into a pervasive drought that has more to do with a warming climate than precipitation, the seven states that rely on the Colorado River are nearing completion of a seven-year
