Since we discussed permafrost pingos today, I thought this story from the University of Alaska Fairbanks was a good sidekick story. It seems there’s a silver lining in melting permafrost after all.

Study: Climate-cooling arctic lakes soak up greenhouse gases

New University of Alaska Fairbanks research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere.
