Ecologist Roman Dial journeyed deep into the Arctic tundra and discovered that shadows showing up in satellite images were in fact a savanna of out-of-place white spruce trees – part of a phenomenon known as 'Arctic greening' #REWIREDGreen wired.com/story/these-tr…
The trees were often well formed and chest-high (this one's probably five years old). And from a planetary perspective, they are bad news, because they are not at all where they are supposed to be. #REWIREDGreen 
As the Arctic warms more than four times faster than the rest of the planet, that’s bringing down the ecological barriers for plants in the far north, and more vegetation is marching toward the pole. #REWIREDGreen
Russell Wong, a graduate student at Alaska Pacific University who worked with Dial, surveys a massive white spruce that's probably around 60 years old, alongside a juvenile. #REWIREDGreen
'Arctic greening' is a blaring warning light on the climate damage dashboard, both for the region and the world at large. Find out more: wired.com/story/these-tr…
