Never Mind Those Earthquakes: Atmospheric Rivers Could Put Sacramento 30 Feet Under Water

The biggest freshwater rivers on Earth don’t flow along the planet’s surface. Instead, they surge and whip through the atmosphere thousands of feet above our heads, carrying 2½ times the amount of water that gushes through the Amazon River at any given time. They’re called atmospheric rivers, or, more aptly, rivers in the sky. These rivers are capable of burying Sacramento under 30 feet of water.
