A hill of permafrost ``slumping'' from global warming near the remote, boggy fringe of North America, 2,200 kilometers (1,400 miles) from the North Pole,

On this edition of Your Call’s One Planet Series, we’ll have a conversation with National Geographic environment writer Craig Welch about the impact of climate change on Arctic permafrost.

The landscape stores one of the largest natural reservoirs of organic carbon in the world in its frozen soils. Researchers suspect that for every one degree Celsius rise in Earth’s average temperature, permafrost may release the equivalent of four to six years’ worth of coal, oil, and natural gas emissions.
