Scientists have discovered an extraordinary area of Siberia in which 15 patches of earth has turned into bubbling grass-covered ground.When the bubble were punctured they emitted methane and carbon dioxide, according to tests, although no more insight has been given to levels of what else was found.
The extraordinary footage was filmed on remote Belyy Island in the Kara Sea off the Yamal Peninsula by a scientific research expedition.

Researchers Alexander Sokolov and Dorothee Ehrich released the footage, although the exact science behind the bubbles has not been given.
One possible explanation of the phenomenon is abnormal heat that caused permafrost to thaw, releasing gases.Most experts now believe they were created by explosions of methane gas unlocked by warming temperatures in the far north of Russia.
Scientists have warned at the potential catastrophic impact of global warming leading to the release into the atmosphere of harmful gases hitherto frozen in the ground or under the sea. A possibility is that the trembling tundra on Bely Island is this process in action.
