OK.. basically the ice layer is melting at a faster rate than normal.. the permafrost. The soil that is uncovered is releasing methane. They did an experiment by collecting some of the gas in a 2 litre bottle. Then the gas was released and some guy lit it and a flame was given off. You might know that methene is one of the most powerful green house gasses. If the whole permafrost melts then something like 900 billion tons of gas will be released.
