Why does everyone go to Antarctica to explore? Why not go to the North Pole?

Also going to the Arctic, China's documentary on the ninth Arctic expedition (5) North China has been on fire these two days. 2065438+At the end of July, 2008, the news that some parts of the Arctic Circle suffered from rare high temperature boarded the global hot search. According to the news, there is a rare high temperature of 30 degrees Celsius in the polar circle in northern Sweden, and the temperature in northern Siberia once reached 32 degrees Celsius. In the same period last year, the average temperature in this area was only 10 degrees Celsius. This extreme high temperature weather shows that the climate change in the Arctic presents a more complicated trend. Although far away from the motherland, China's ninth scientific expedition to the Arctic got news from the domestic media. Unlike the fiery heat in some parts of the Arctic Circle, the expedition team that is marching on the Arctic Ocean still feels the biting cold. The unusual climate made the team members more deeply aware of the necessity of scientific investigation in the Arctic. At 4 o'clock in the morning of August 1 year, the temperature in Chukchi Sea dropped below zero degrees Celsius, and the expedition members who were working on the back deck of the "Snow Dragon" ship even stood up with cold. Even if they occasionally walk on the deck, the players are fully armed. When the wind blows in the Arctic Ocean, everyone can't help but wrap up their cotton-padded clothes. Since entering the ice area, the "Snow Dragon" ship will make a few muffled noises from time to time, followed by a violent collision, and then continue to break the ice. In the past few days, the temperature has been kept between MINUS 4 degrees Celsius and zero degrees Celsius. Judging from the temperature and ice conditions, there is no obvious abnormality in the Arctic Ocean as in previous years. It can be seen that the extreme weather process in the Arctic Circle mainly occurs in northern Europe, and has no direct impact on the western Arctic Ocean where the expedition team is located. The Arctic is an important source of cold air in China. The formation of Arctic sea ice regulates the strength of East Asian winter winds and is an important factor affecting China's climate. Therefore, the study of Arctic climate change is not only an important topic for scientists all over the world, but also has important guiding significance for forecasting the climate change in China and the development and utilization of Arctic waterway. The rapid change of Arctic climate is an environmental and climatic problem that human beings are facing and paying attention to. Since the 1990s, China has begun to explore the Arctic and made nine arctic expeditions, which provided a data base for studying the changes of the atmosphere, sea ice and ocean. Since China's eighth scientific expedition to the Arctic on 20 17, China has started the pilot work of operational observation for the first time. During the "Eight North" period, two sets of anchor submersibles were deployed, and the observation data of marine environment for one year were obtained, which can support China's research on the rapid change of climate environment in the Arctic to some extent. However, the basis of observation and investigation is still weak and still in the primary stage. The arctic climate system is complex and changeable, so it is not enough to observe and investigate a sea area or one or two stations for one year, and it is difficult to achieve scientific research purposes. Therefore, it is not only a basic work, but also a very necessary work to carry out ocean and climate observation in the Arctic, especially long-term normalization investigation. China's ninth Arctic scientific expedition further expanded the scope of operational concept/monitoring work, and for the first time, it combined operational concept/monitoring work with scientific research projects to promote each other and serve the study of Arctic climate and environmental change. In order to better carry out scientific investigation in the Arctic, it is necessary to strengthen international cooperation. The expedition team cooperated with the plan of Mosek International Drifting Ice Station, made good preparations, provided valuable observation data, and made due contributions to this plan in China. Although China has made some progress in the study of Arctic climate and environmental change, it can only be regarded as the first step. Looking forward to the future, if an optimized long-term continuous observation/monitoring network can be established in the Arctic region, we can make a more targeted pulse diagnosis of climate change in this region and provide a higher level of scientific support for forecasting and coping with climate change.
