... "These are not dead samples by any means," says microbiologist and geochemist Tristan Caro, a PhD student at the University of Colorado Boulder (CU Boulder) during the study.

"They're still very much capable of hosting robust life that can break down organic matter and release it as carbon dioxide."

Caro and his colleagues aren't just raising the undead for the thrill of it.

As our fossil fuel addiction continues to warm the world, Arctic permafrost " the frozen soil, ice, and rocks beneath nearly a quarter of the Northern Hemisphere's landmass " is melting, releasing the greenhouse gases stored within.

As these layers thaw, many microscopic creatures -- like the ones in the team's samples -- will come to life, and, with newfound appetites, consume whatever decaying matter surrounds them. This will release more methane and carbon dioxide into the atmosphere, further contributing to climate change. ...

Can you say, "tipping point?"

I knew you could.

Aside from the CO2 aspect of this discovery, I have a concern about age-old "life" that has been resurrected from the bowels of a military tunnel, and how that "age-old life" may possibly infect the current life of this planet.
