Videoclips:

Permafrost: The tipping time bomb. YouTube clip on the potential release of carbon from thawing permafrost. Several RCN members are featured in this clip including Kevin Schaefer, Vladimir Romanovsky, Charles Miller and Ben Abbott.  

This short video features the Permafrost Carbon RCN member Katey Walter Anthony as she explains methane bubbling and the potential methane release when permafrost thaws

Watch this video by Sara Godsey, Michael Gooseff & Antoni Lewcowicz (ARCSS/TK) to see what happens when permafrost thaws
