ARCTIC SINKHOLES
WEDNESDAY, MARCH 13, 9 PM

Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive craters. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas.

A.I. REVOLUTION - NEW
WEDNESDAY, MARCH 27, 8 PM

On the picturesque bluffs at the very tip of the island of Martha’s Vineyard, disaster looms. The historic Gay Head Lighthouse is soon to become the next victim of the persistent erosion of the island’s cliffs. Built in 1856, the more than 400-ton structure soars 175 feet above the sea. But over the years, storms and the raging ocean have eroded the headland away.
