As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gasses to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from these perpetually frozen lands could be on par with emissions from large industrial countries. However, new research led by a team of microbiome scientists suggests those estimates might be too low.

However, new research led by a team of Colorado State University microbiome scientists suggests those estimates might be too low.

It all started with an observation. Earth Scientist James Stegen, who studies the microbes, chemistry, and water in rivers, noticed something peculiar

We can access these foods' health benefits because the microbes in our guts happily feast on them, breaking them down into smaller chemical components. Microbiome scientists at Colorado State University wanted to know if microbes can also break down those same polyphenols in systems outside the human...
