                                        As arctic temperatures rise, we expect to see dramatic changes due to thawing permafrost soils. Permafrost stores half the total amount of carbon (C) found in soils globally, and twice as much C as is found in the atmosphere. As permafrost thaws, the stored C becomes vulnerable to loss because low temperatures no longer limit […]
