VoltResearch on the drift of the icebreaker Polarstern across the Arctic Ocean for a year is rarely mentioned, unless it is added that this is the greatest Arctic expedition ever. What is true. But this is not the reason why the expedition’s name Mosaic is so unique. On the contrary, for the first time, scientists from different disciplines collected all the data for an entire year, which is necessary for understanding the climate system of the Arctic-which in turn makes the mechanism of global warming easier to understand. Expedition leader and atmospheric physicist Markus Rex and sea ice physicist Stefanie Arndt-in the year after the expedition ended-were very correct in the “Break the Wall” talk. Regarding climate change as a core challenge, necessary reflections on society, politics, and economy have run through many events in “Falling the Wall”; a young company that develops biodegradable packaging was named the “Science Start-up Company” of the year, It also discussed how socio-economic changes and the “Green New Deal” can be successful.Two scientists’ report Alfred Wegner Institute But focus on research that can understand the consequences of human activities on the planet and why taking action now is so important.
As far as the discovery of the Arctic climate system is more like a snapshot so far, this expedition removed a wall of research. The journey to the Arctic Ocean is much shorter, and in winter when the ice is impenetrable, there has never been any one-with one exception: Fridtjof Jansen let the wooden boat Fara in 1893 Mu froze in the polar ice and continued to advance with the ice, so he proved that there was a transpolar drift. “We followed Nansen’s ideas,” Marcus Rex said, admiring this brave pioneer of polar research can be heard in his voice. He doesn’t know if he and his companions will survive this adventure. Come down.

Like Nansen’s team, the Polarstern research team set off when the Arctic sea ice is still navigable, looking for suitable ice floes in the Siberian part of the Arctic, where the ship should freeze. At the beginning of October, the captain turned off the engine, which was a special moment: “From then on, we are in the hands of nature,” said Markus Rex. “We don’t know where we will be the next day.” Over the next few months, drifting brought Polarstern to the North Pole, otherwise the area would be inaccessible in winter. This is almost the route of Fram drifting. However, it took three years, which is also a sign of climate change in the Arctic: the ice is now thinner and therefore more dynamic, and transpolar drift is accelerating.
Snow, water, ice core
Antarctica is warming faster than any other region on the planet, and it has now risen by 3 degrees, which is nearly 2 degrees higher than the global average temperature rise caused by climate change so far. “Nonetheless, people can ask why we should be interested in the far North Pole,” Stephanie Arndt said, and she immediately replied: “What happens in the North Pole will not stay in the North Pole.” The warming of the region has produced. The impact, in short, the global air circulation, is therefore part of the cause of extreme weather conditions, such as being more and more common in Europe, Asia and North America.
