Regrowing forests could provide climate change help

A new study shows that allowing cleared forest to grow back can help cut down carbon dioxide emissions. Temperate forests in eastern North America are storing only part of their historic carbon sequestration potential, according to ecologists at McGill University and the University of Wisconsin. "There's quite a lot of potential for the future," said Jeanine Rhemtulla, a postdoctoral fellow at McGill and lead author of a study published in this week's Proceedings of the National Academy of Sciences.
