GAINESVILLE, Fla., June 2 (UPI) -- As frozen arctic soil thaws due to climate change, U.S. scientists say bacteria will break down large amounts of carbon, sending it into the atmosphere.
Although plants will initially proliferate, nurtured by balmier conditions and an increasing abundance of the greenhouse gas they depend on for growth, University of Florida researchers said they don't expect plant growth will be able to blunt the carbon release.
