S46 E7 Saving the Dead Sea

本集简介

The Dead Sea is dying: Since 1976, its level has dropped more than 100 feet, leaving its coastline pockmarked with thousands of sinkholes. But after more than a decade of research and debate, scientists, engineers, and political leaders have come up with a daring plan: connect the Red Sea to the Dead Sea by way of a massive desalination plant. If it's successful, the project could not only revive the sea, but also help ease political tensions and water shortages in the region. NOVA follows this unprecedented endeavor—perhaps the world's largest water chemistry experiment—as scientists race to save the Dead Sea and bring water to one of the driest regions on Earth.

The Next Pompeii

In the shadow of Italy's Vesuvius, a lesser-known volcano rumbles: Campi Flegrei. An eruption could endanger the millions of residents of the city of Naples. Scientists gain new insights into what happened in nearby Pompeii, and dig into the unique geology of Campi Flegrei. How will they know if the ever-shifting ground is reaching a breaking point? And can an innovative eruption warning system prevent Naples becoming the next Pompeii?

Inside the Megafire

From the front line of the Camp Fire, the deadliest wildfire in California history, NOVA tells the stories of residents who had to flee for their lives during the 2018 fire season. Scientists racing to understand what's behind the rise of record-breaking megafires across the American West take to the forest, and even a fire lab, in search of answers. They investigate how forestry practices, climate change, and the physics of fire itself play a role in the dramatic increase in wildfires in recent decades.
