In a new study by Anouschka Hof, Roland Jansson and Christer Nilsson, all at Umeå University in Sweden, the trio of scientists found that, in most cases, global warming will actually give a boost to Arctic and subarctic life. Looking at 61 terrestrial mammal species that currently inhabit high-latitude Europe the scientists found that, under climate conditions forecast for the year 2080, the majority of the species will see their ranges expand. They found that warming will actually bring in more species from further south, increasing biodiversity in the region. And, even in their worst-case scenario, they expect at most one species to go extinct: the Arctic fox. But, they suspect that this worst-case scenario is just that, a nightmare scenario unlikely to unfold.
