"We know that permafrost soils contain double the amount of carbon that's in the atmosphere now," Balser said. "But how much of that is really going to wind up in the sky" as the permafrost thaws?

That is from the article. 

The nit-wit globalists who try to contend that CO2 (plant food) is bad, 
  and insist that elevated levels of CO2 are caused by man should study the Earth's long history.

Its normal for the Earth's atmosphere to hold several times greater CO2 than it has now.

And plants thrive with more CO2. 
Which leads to animals thriving too.
