The Carbon Threat

Kenyon Kassaiuli, Jonah Andy, Larry Charles, and Reese John cross a flooded walkway in Newtok, Alaska, USA, on an early summer bird hunt. Their village is rapidly sinking and shrinking as a result of warming weather, thawing permafrost and erosion.

The Arctic permafrost is thawing at a faster rate than climatologists predicted, releasing carbon gases that could speed up global heating. Permafrost is carbon-rich frozen soil that covers 24% of the Northern Hemisphere land mass, encompassing vast stretches of territory across Alaska, Canada, Siberia and Greenland. It is a combination of soil, rocks and sand held together by ice and containing large amounts of organic carbon—frozen plant material that doesn’t decompose. As permafrost thaws, this material rots, releasing carbon dioxide and shorter-lived methane. Methane can be between 25 and 86 times more potent than CO2 as a greenhouse gas, depending on the timeframe of measurement. The thaw impacts people living in the region—particularly indigenous communities following centuries-old lifestyles. Thawing permafrost undermines house foundations, makes the landscape more difficult to navigate and causes ice cellars (homemade freezers dug into the permafrost) to flood and provisions to spoil.
