Finding Methane Bubbles in Permafrost

The ground is made up of both ice and frozen soil called permafrost. As the permafrost thaws, the ground sinks and floods. The ice traps gases bubbling up from the decomposing permafrost. Methane traps 30 times more heat in the atmosphere than C02. As the world gets hotter, the permafrost melts faster – releasing ever-greater quantities of this dangerous greenhouse gas.
