A study by researchers from the University of Exeter, the University of Helsinki and the Finnish Meteorological Institute reveals a grim future for the world's permafrost - landscape covered in frozen soil – concluding that such regions are on the brink of thawing irrespective of what actions are taken to contain global warming.

Periglacial zones, spanning over a quarter of the Earth’s land area, could disappear entirely by 2100, a development that threatens not only local geological processes but also reduction in biodiversity to a dramatic extent, writes New Atlas.

Further, unfreezing of permafrost would release long-trapped carbon in the atmosphere, thus worsening the problem of climate warming, notes Inside Climate News.
