Renowned marine biologist Dr. Sylvia Earle reveals why the dual threats of ocean pollution and overfishing could have a devastating impact on mankind.
Discover how New York City – overwhelmed in 2012 by Superstorm Sandy – has learned from that disaster, and must defend itself against rising seas and the next big storm. With 520 miles of shoreline and no coastal protection, engineers and urban planners are tackling the problem with urgency and creative engineering.
Geologist Prof Iain Stewart shows how the continent of Africa was formed from the wreckage of a long lost supercontinent. He discovers clues in its spectacular landmarks, mineral wealth and iconic wildlife, that help piece together the story of Africa's formation. But he also shows how this deep history has left its mark on the modern day Africa and the world.
In just one devastating month, Houston, Florida, and the Caribbean were changed forever. In summer 2017, three monster hurricanes swept in from the Atlantic one after another, shattering storm records and killing hundreds of people. First, Harvey brought catastrophic rain and flooding to Houston, causing $125 billion in damage. Less than two weeks later, Irma lashed the Caribbean with 185 mile per hour winds - and left the island of Barbuda uninhabitable. Hot on Irma's heels, Maria intensified from a Category 1 to a Category 5 hurricane in just 15 hours, then ravaged Puerto Rico and left millions of people without power. As the planet warms, are these superstorms the new normal? How well can we predict them? And with hurricane season just around the corner, does the U.S. need to prepare for the reality of climate refugees? NOVA takes you inside the 2017 superstorms and the cutting-edge research that will determine how well equipped we are to deal with hurricanes in the future.
Last century, earthquakes killed over one million, and it is predicted that this century might see ten times as many deaths. Yet when an earthquake strikes, it always takes people by surprise. So why hasn't science worked out how to predict when and where the next big quake is going to happen? This is the story of the men and women who chase earthquakes and try to understand this mysterious force of nature. Journeying to China's Sichuan Province, which still lies devastated by the earthquake that struck in May 2008, as well as the notorious San Andreas Fault in California, Horizon asks why science has so far fallen short of answering this fundamental question.
