The record-breaking rain soaking the Southwest U.S. in recent weeks still won't be enough to eliminate the megadrought status in the notoriously arid region completely, according to researchers.

Summer monsoons in the Southwest are difficult to forecast with total accuracy, but the future of the temperamental rainstorms under climate change is an even bigger mystery.

Scientists are studying mineral deposits in the caves of the Grand Canyon to understand the impacts of climate change.

They chose an ancient calcium projection, called stalagmite, from the floor of an undisturbed Grand Canyon cave and studied its geochemistry. The research team was led by the University of Nevada, Las Vegas, and included the University of New Mexico.

The Grand Canyon, known for its majestic valleys and millennia-old rock layers, has now unveiled another marvel — its extensive cave systems that could potentially unlock secrets about climate change.
