In the forested depths of eastern Congo lies Virunga National Park, one of the most bio-diverse places in the world and home to the last of the mountain gorillas. In this wild, but enchanted environment, a small and embattled team of park rangers - including an ex-child soldier turned ranger, a carer of orphan gorillas and a Belgian conservationist - protect this UNESCO world heritage site from armed militia, poachers and the dark forces struggling to control Congo's rich natural resources. When the newly formed M23 rebel group declares war in May 2012, a new conflict threatens the lives and stability of everyone and everything they've worked so hard to protect.
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.
