Permafrost is a thick subsurface layer of soil that remains frozen throughout the year. What impact will permafrost thaw have on ecosystems, communities and climate? What transformative solutions exist to address and reverse the thaw? Share your expertise, post resources, ask questions and join the conversation!

REGISTER FOR GROUNDED'S UPCOMING PANEL HERE: https://hopin.com/events/why-delaying-permafrost-thaw-is-critical-to-our-survival

Permafrost is “permanently” frozen ground that covers approximately 24% of the Northern Hemisphere, including large parts of Alaska, Canada, Greenland and Siberia. The frozen layer of ground holds methane and double the amount of carbon dioxide that’s currently in the atmosphere and the warming global temperature is resulting in a loss of these greenhouse gas stores.
 
Consequently, permafrost thaw has become both a product of and contributor to the climate crisis. In this panel, we will address and highlight innovative solutions to this alarming phenomenon and explore how policy and individual action can impact the outcome. Although permafrost is only occupying a quarter of the earth’s surface, this is an urgent global crisis that requires collective global action.
 
Join us tomorrow Septemebr 21 at 10 am PT as we dive deeper into a discussion featuring Arctic researchers, climate solutionists and those who have dedicated their lives to addressing the climate crisis as a means of our survival.

Interesting and hopeful findings from the Tibetan Plateau permafrost region: https://www.pnas.org/content/118/33/e2015283118:

"Cold regions contain vast stores of permafrost carbon. Rapid warming will cause permafrost to thaw and plant respiration to accelerate, with a resultant loss of CO2, but could also increase the fixation of CO2 by plants. A network of 32 eddy covariance sites on the Tibetan Plateau, which has the largest store of alpine permafrost carbon on Earth, shows that this region functions as a net CO2 sink. Our sensitivity analyses, experiments, and model simulations consistently showed that the fixation of CO2 by plants outpaces the loss of CO2 from permafrost and accelerates plant respiration. This indicates a plant-dominated CO2 balance on the Tibetan Plateau, which could provide a negative feedback to climate warming."

“We don’t have time for a perfect solution. We need to act on the knowledge that we do have.”
