Advent Calendar 2019
Our online science advent calendar is back! Each day until December 24, we will open a door of our advent calender for you to dazzle you with images from science and provide the scientific background to the image. Enjoy!
This year's background image of our advent calendar takes us far north. Nowhere else is climate change so starkly visible: the Arctic sea ice is melting faster than ever before, and by the end of this century, the North Pole could be completely free of ice in the summer.
