The Greening of the Arctic Tundra

One of the most inhospitable places in the entire world, the Arctic Tundra, is now undergoing an amazing transformation. Rising temperatures in the Arctic circle have caused changes in vegetation in the last few decades. Plants are growing taller, there is less bare ground devoid of vegetation, and even some shrubs are growing. It is far from being an agricultural breadbasket, but it is well on its way to becoming a more lively ecosystem. A recent study from biologists at the University of Gothenburg, Sweden documents the dramatic changes that are occurring.
