The melting permafrost of Siberia, Russia
Siberia is home to permafrost containing 1.5 trillion tons of carbon. As expert Sergey Zimov told the Huffington Post, “Here, total carbon storage is like all the rain forests of our planet put together.”
This is of concern to scientists, who note that the permafrost has started melting at a rapid pace in the past few decades. The faster it melts, the faster this carbon enters the atmosphere.
