The Permian extinction 250 million years ago was the largest mass extinction on record, and among the losers were conifers that originally blanketed the arid interior of the supercontinent Pangaea. Now researchers say that climate change led to the proliferation of tree-killing soil fungi that helped destroy the forests -- something that could happen as a consequence of global warming today.
