Warming of the Arctic is the situation of frequent above-average temperatures in the Arctic Sea area, compared with the long-term normal temperatures. These anomalies can be seen over the last three or four decades. A view of this can be obtained from registrations by meteorologists. Within the Arctic circle, there are a number of staffed or automatic weather stations, mainly in the inhabited areas but also further north. Because of the ice-albedo effect, snow and ice-covered areas like the arctic are warming up faster than the global average. The melting of snow and ice reveals the darker earth or sea so the albedo in that area decreases and less solar radiation is reflected back into the atmosphere. An open Arctic Sea absorbs more warmth of the sun than an ice-covered sea that reflects a lot. This stimulates a further rise in temperature once it has started.
