The unique Arctic ecosystem is hardest hit by climate change. The MOSAiC expedition has witnessed dramatic dynamics. Drifting with the ice for an entire year, they endured the extreme cold. Arctic storms and a constantly changing floe... Never before so close to the North Pole in winter, never before such essential data was gathered. Synchronous samples and year-round observations, a milestone in climate research. We have seen how the fate of the Arctic ice connects to us. How extensive melting and erosion strongly affects weather, ocean and life, how this knowledge is essential for assessing the future. Our responsibility is to share this insight. To provide scientific knowledge for pressing political decisions... ...to build a path to the future we want. #ClimateChange #MOSAiCexpedition #AWIresearch
