WATCH: Freaky footage of earth 'bubbles' as global warming 'causes leaking methane gas'
FREAKY footage of the earth’s surface bouncing has emerged after a strange discovery by scientists.
Shocking footage of bubbles which have formed under the earth has emerged
Scientists discover underground methane bubbles in Siberia
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.
Alexander Sokolov said that this summer is unusually hot on the Arctic island, a sign of which is polar bears moving from the frozen sea to the island.
But the discovery comes with a worrying warning.
The ground literally bounced under the boots of the scientists
Scientists have said a potentially catastrophic impact of global warming is it leading to the release of harmful gases that were frozen in the ground or under the sea.
A possibility is that the trembling tundra on Bely Island is this process in action.
Further south on the Yamal and Taimyr peninsulas, scientists are observing another phenomenon as a number of craters have suddenly formed.
Crates on Yamal Peninsula - known to locals as "the end of the world" - are now at the centre of a number of theories.
From meteorites to stray missiles fired by Vladimir Putin's military to extraterrestrial visitors, all kinds of concessions have been drawn.
There was no solid explanation given for the bubbles under the ground
Most experts now believe they were created by explosions of methane gas unlocked by warming temperatures in the far north of Russia.
On Yamal, the main theory is that the craters were formed by pingos - dome-shaped mounds over a core of ice - erupting under pressure of methane gas released by the thawing of permafrost caused by climate change.
The Yamal craters, some tiny but others large, were created by natural gas filling vacant space in ice humps, eventually triggering eruptions, according to leading authority Professor Vasily Bogoyavlensky, of Moscow's Oil and Gas Research Institute.
Recently there were accounts of a 'big bang' leading to the formation of a crater on the Taimyr Peninsula.
The noise could be heard up to 100 kilometres and some residents claimed to see a “glow in the sky”.
A crater was found in the Yamal Peninsula which has grown in size
The crater was first seen by reindeer herders who almost fell into it soon after the 2013 eruption.
Since its discovery it has increased 15 times in size.
It is expected to be even wider now but no recent scientific surveys have been made to the remote site.
