Thawing permafrost threatens to intensify global warming, sending the planet beyond the 2 degrees Celsius (3.6 degrees Fahrenheit) of increases that envoys at United Nations climate talks have set as a maximum.

Frozen soils that cover a quarter of the land area in the northern hemisphere contain 1,700 gigatons (1,700 billion tons) of carbon, twice the amount currently in the atmosphere, the UN Environment Program said today in a report released at the latest round of treaty negotiations in Doha.
