For most people who live in temperate regions of the world and particularly those who live in urban areas, global warming is very much a theoretical concept. In the Arctic things are very different. The changing climate has already made its presence felt on both the people and wildlife of the region. A study carried out by NASA predicts that the Arctic Ocean will have no summer ice by the year 2100. Without the ice to reflect the sun's rays, the Arctic Ocean will become warmer. If NASA's prediction is correct, Polar Bears will become one of the first northern casualties of Global Warming. This article explorers the impact across the Arctic today.
