National Geographic's Strange Days on Planet Earth
Around the globe, scientists are racing to solve mysteries. Unsettling transformations are sweeping across the planet, and scientists are discovering ways that seemingly disparate events are connected. Crumbling houses in New Orleans are linked to voracious creatures from southern China. An asthma epidemic in the Caribbean is linked to dust storms in Africa. Scientists suspect we have entered a time of global change swifter than any human being has ever witnessed. Hosted by actor Edward Norton.
