Which places on earth are poised to generate the next mega-tsunamis and the science of what happens as the wave emerges from open ocean and bears down on land.
Scientists are just now unlocking the amazing secrets of how rain is made; some raindrops form around micrometeorites from outer space, others are created by bacteria that float into the upper atmosphere.

The disaster began during a routine systems test at reactor number four of the Chernobyl plant located near the town of Pripyat, on April 26, 1986. After a power surge, an emergency shutdown was attempted and after a subsequent power spike, there was a reactor vessel rupture and a series of steam explosions. The cascading course of events led to exposing the graphite moderator of the reactor to the air, causing it to catch fire. This sent a plume of highly radioactive fallout into the atmosphere. The fallout from Chernobyl prompted mass evacuations as it drifted over an extensive geographical area, including the western Soviet Union and Europe. Over 350,000 people were resettled from contaminated areas of Belarus, Russia, and the Ukraine. Thirty-one deaths are directly attributed to the accident, and all the deaths were among reactor staff and emergency workers. This is the kind of atmosphere Nelson and Ochota are investigating on Life After: Chernobyl as they attempt to determine how the radiation continues to impact the affected areas. They are allowed to stay for as long as they need to in order to conduct their ground-breaking research, but the duo must also be sure to take the necessary safety precautions. Broadway World noted in their Life After: Chernobyl article that by staying in the area for too long, the radiation exposure could reach dangerously high levels in their bodies, and they must always monitor the radiation levels.

Disastrous hurricanes. Widespread droughts and wildfires. Withering heat. Extreme rainfall. It is hard not to conclude that something’s up with the weather and many scientists agree. It’s the result of the weather machine itself—our climate—changing, becoming hotter and more erratic. In this two-hour documentary, NOVA will cut through the confusion around climate change. Why do scientists overwhelmingly agree that our climate is changing, and that human activity is causing it? How and when will it affect us through the weather we experience? And what will it take to bend the trajectory of planetary warming toward more benign outcomes? Join scientists around the world on a quest to better understand the workings of the weather and climate machine we call Earth, and discover how we can be resilient—even thrive—in the face of enormous change.
