Researchers Predict Megadrought in Southwest

Researchers from Princeton and Columbia universities report that the Southwest's drought could last 90 years. Their research shows a marked increase in climate temperatures and indicates that these temperatures will continue their climb.

The water level of the Colorado River, which supplies most of the region's water, has already dropped by 15%.

With water infrastructure uncomfortably stressed in the Southwest and elsewhere, we face tough questions: How long can the system support current demand, let alone development? How will our supplies be allocated? Clearly, we must focus on conserving the supply we have with water-efficient practices and technologies.
