In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.

Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive sinkholes. 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. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future.

How could a body of water as big as the Mediterranean just…disappear? It would take decades and more than 1,000 research studies to even start to figure out the cause — or causes — of one of the greatest vanishing acts in Earth’s history.
