permafrost melt
Arctic ground softening
Permafrost melt is the thawing of permanently frozen ground in polar and high-altitude regions.
As global temperatures rise, permafrost that has remained frozen for thousands of years begins to soften, releasing stored carbon and methane into the atmosphere.
The process destabilizes infrastructure and accelerates climate change: Permafrost melt is causing roads and buildings in Alaska to buckle.
