Most Arctic Species Will Benefit From Global Warming

January 16, 2013

Global warming will benefit most Arctic species, a team of scientists report in the peer-reviewed journal PLOS One. In fact, global warming will allow Arctic species to expand their range rather than be confined, says James Taylor in Forbes.

Many global warming alarmists felt that Arctic and subarctic regions would be susceptible to climate change. However, warming will decrease the area of tundra and extend temperate climates further north. Scientists modeled the effect of global warming in European high latitudes and found:

  • Many Arctic and subarctic species (43 of 61) benefited because they were able to expand their range.
  • In fact, climate change up to 2080 will favor most mammals in subarctic Europe.
  • Some species, such as alpine species, which are cold-climate specialists, may not benefit from the warming.
  • However, no species is threatened to go extinct.

Because species have a wider range to live in, species richness is likely to increase substantially. Even if humans are to alter the landscape that prevents species from expanding, they would still not be in danger of going extinct.

Scientists predict that these species are able to adapt because arctic regions have experienced large climatic shifts in the past that filtered out any sensitive and range-restricted taxa. Furthermore, scientists find that the greater threats to arctic and subarctic mammals are constraints on their dispersal ability and changes in community composition, not climate change.
