From the Arctic Ocean to the ocean depths of Japan, from the frozen lands of Siberia to the research lab, what impact will this greenhouse gas have on our climate?

A compelling investigation into the major environmental challenges of our century.

This rather forgotten gas from our planet’s past has just made a crashing comeback center stage.

Some scientists are studying methane rejections while other researchers are examining the possibility of extracting methane hydrate from the ocean floor.

A phenomenal new energy resource - but one whose extraction can be dangerous.
