The new episode "Namib: Skeleton Coast and Beyond" takes viewers to the Namib Desert, widely believed to be among the oldest such deserts on Earth. It's home to more indigenous species than any other such environment — but how is that possible? Temperatures there climb as high as 122 degrees F., and annual rainfall is measured in millimeters. The answer, in part, lies with a mysterious sea fog that sweeps across the Skeleton Coast. Helena Bonham Carter narrates.
