As the frozen soil in the Arctic thaws, bacteria will break down organic matter, releasing long-stored carbon into the warming atmosphere. At the same time, plants will proliferate, nurtured by balmier temperatures, more nutrients from decomposing soil and the increasing abundance of the greenhouse gas they depend on for growth.

by Pierre-Henry Deshayes TROMSOE, Norway (AFP) – Potentially fatal to the polar bear, global warming has already left its mark on the species with smaller, less robust bears that are increasingly showing cannibalistic tendencies.
