Mammoth dung, prehistoric goo may trigger global warming, thanks to thawing permafrost


ce thawing at the poles has been a big concern for scientists especially for the last decade - considering it a serious symptom of global warming, leaving the coastal regions at the risk of sinking under the seas and the polar animals’ going extinct.

But, the earth is actually ‘doubly suffering’ from global warming threats with the thawing of permafrost - thanks to the dramatic climate change activities.

It is the re-exposure of the mammoth dung and prehistoric goo to the air that may accelerate global warming faster than even assumed! — these being ‘organic matter’.

It was for millennia, these layers of animal waste and other organic matter have been left behind by the prehistoric creatures that romped the Arctic tundra, but were sealed inside the frozen permafrost.

But, with the changing climate, the most-happening thawing of the permafrost is leaving the prehistoric organic goo and dung exposed to air with its dormant-microbes springing back to action! - eventually adding to the already-dreading ‘carbon dioxide emissions’ and even methane gas — the even more damaging ingredient.

Thus, it seems, besides the already defined accelerators of global warming — the thought of whose devastative actions already send a chill down the spine — there are many more factors that are actually adding on to the planet’s aliment and may eventually push it to the point of no return.
