Permafrost resilience in the era of climate change and Earth system modeling

Permafrost resilience in the era of climate change and Earth system modeling In this analysis from Everest Group, explore the resilience of permafrost in the context of climate change and earth system modeling, with an emphasis on how science and technology are enhancing Arctic stability and global risk management. Permafrost – perennially frozen ground composed of soil, rock, and organic material – underpins nearly one-quarter of the Northern Hemisphere’s land surface. It stabilizes Arctic ecosystems, supports infrastructure, and locks away vast stores of carbon accumulated over millennia. But with global temperatures rising, this frozen foundation is rapidly degrading. Thaw-induced disruptions extend far beyond local impacts. Crumbling buildings, collapsing roads, and fractured pipelines are now typical across Alaska, Northern Canada, and Russia. Simultaneously, methane and carbon dioxide emissions from thawing permafrost contribute to a warming feedback loop, raising concerns about tipping points in the global climate system (Schuur et al., 2023). These cascading effects demand urgent scientific attention and an international response.
