7. Scary: North Pole 20°C hotter than normal

Last week, temperatures near the North Pole were an unheard of 20°C warmer than normal, researchers have reported.
The Arctic is currently in the midst of polar night, where the Sun hardly ever rises. Usually, it’s the time when things get really cold and vast, thick ice sheets form for the winter.
But this year, temperatures are much warmer than usual.
And even though sea ice is forming again after reaching its annual low in September, it’s doing so much slower than usual. In fact, so far the amount of ice coverage is even lower than the record-breaking low of 2012.
Changes in the Arctic will not only affect local people and ecosystems but also the rest of the world, because the Arctic plays a special role in global climate. See also http://www.greenfacts.org/en/arctic-climate-change/
