New Birch Trees in Arctic Speeding Climate Change

Growing up in the foothills of the Adirondacks, and having spent other formative times of my life in Russia, I have a deep, abiding love for birch trees, and so it comes as VERY unwelcome news that their northward expansion into the Arctic tundra may contribute to climate change.
"[U]sing a novel methodology based on measuring the radiocarbon content of the carbon dioxide being released, the researchers found that the birch trees appeared to be stimulating the decomposition of soil organic matter. Thus, the research was able to identify a mechanism by which the birch trees can contribute directly to reducing carbon storage in soils."
