In April, 2010 the eruption of Iceland's Eyjafjallají¶kull volcano turned much of Europe into an ash-strewn no-fly zone, stranding millions of travelers. But was Eyjafjallají¶kull just the start? Now, an even more threatening Icelandic volcano, Katla, has begun to swell and grumble. Two more giants, Hekla and Laki, could erupt without warning. Iceland is a ticking time bomb: When it blows, the consequences could be global. As CGI takes us inside these geological monsters, we meet atmospheric scientists who are working to understand just how devastating an eruption could be—not just for air travel but for the global food supply and for Earth's climate. Could we be plunged into years of cold and famine? What can we do to prepare for the disaster to come? (Premiered January 2, 2013)
