Why study the effects of global warming on the Arctic?
For years, climate scientists have believed that the Artic would likely be one of the first regions to be affected by global warming and would likely experience greater warming than the rest of the world. Recent evidence has validated these concerns. While the world as a whole warmed about 1oF over the entire 20th century, parts of the Arctic have warmed by 4-5oF just since the 1950s. The Arctic continues to warm at a rate about twice as fast as rest of the world. Scientists, as well as the indigenous people of the Arctic, have noticed dramatic changes in the Arctic environment that has affected ecosystems and wildlife, human settlements and infrastructure, and the way of life of indigenous peoples. For these reasons, the ACIA was undertaken to evaluate whether these changes are caused by human activities; how Arctic climate change may affect climate change in the rest of the world; and the risks of continued global warming for the Arctic, its people, and its ecosystems and wildlife.
