Why so dangerous? These frozen bubbles are filled with methane caused by organic material that is being broken down by bacteria. Once the ice melts, the bubbles come to the surface and burst, releasing massive amounts of methane into our atmosphere and further contributing to the warming of the planet. They aren’t the worst polluters in the world, but as permafrost melts in different parts of the formerly frozen world, there is a lot more methane being released.
