Climate change is reshaping Arctic rivers in different ways Water in the Arctic may seem quiet, but it affects the whole planet. Rivers carry melted snow into the ocean, shaping ice, currents, and global temperatures. Something has started to change. Scientists tracking these waters now see patterns that do not follow a simple trend. Some regions are getting wetter, while others are drying out. The old idea that a warming Arctic would simply mean more water everywhere is starting to fall apart. Watching Arctic rivers from space For years, researchers depended on measuring stations planted along riverbanks. These gauges recorded how much water flowed through major rivers. But the Arctic is vast and difficult to reach. Keeping those stations running costs time and money, and many have been shut down. So scientists looked up. Satellites now circle Earth, quietly collecting data about water, snow, soil, and rainfall. By combining these streams of information, researchers have built a new way to track how water moves across the Arctic without setting foot on the ground. This effort comes from a team working through the European Space Agency’s STREAM-NEXT project. The group, led by researchers from Italy’s National Research Council and the University of Perugia, created a model that uses only satellite...

The Arctic reached a historic low after the loss of sea ice, a consequence of advancing climate change The Arctic sea ice is going through one of its most critical moments. The frozen surface has reached historical minimum levels. Furthermore, this phenomenon is directly linked to the increase in global temperatures. Consequently, the polar region is warming faster. Therefore, the natural dynamics of the ice are altered. Likewise, the global climatic balance is compromised. In this context, scientists warn about accelerated changes. Thus, the Arctic is consolidated as a key indicator of warming. How sea ice forms and why it is decreasing The sea ice forms when the ocean water freezes in winter. Then, during the summer, part of it melts. However, the natural cycle is being modified. Additionally, each winter less ice is formed than in previous decades. As a result, the system loses recovery capacity. Therefore, the total surface progressively decreases. Likewise, the increase in temperatures impacts unevenly. Thus, the Arctic suffers a more intense warming than other regions. Recent data confirms a worrying trend The annual ice maximum was recorded on March 15. Moreover, it occurred earlier than the previous year. Consequently, the extent reached 14.29 million square kilometers, according to the National Snow and Ice Data Center (NSIDC) of the United States. Therefore, it...

Map centered on western Alaska showing the satellite derived sea ice thickiness (meters) for the week of March 15-21, 2026. Ice thickness ranges from less than 0.3 meters in the open ocean in southeast Bering Sea to over two meters some areas in the Chukchi and Beaufort Seas.

Satellite-derived sea ice thickness around Alaska for the week ending March 26 courtesy AWI. Ice is thicker than 2011-25 median along the Alaska Chukchi coast and in the southeast Bering Sea, where the 15-year median extent is zero. Ice in the northern Bering Sea rather thin. #akwx #Arctic #SeaIce

Under the Ice: Why Arctic Science Needs More Divers A new generation of scientific divers is being trained to operate beneath Arctic ice, highlighting the growing need for specialised expertise to support research in rapidly changing polar environments. Recent training initiatives in northern Finland demonstrate the importance of expanding the number of professionals capable of conducting under-ice research. These programmes aim to equip scientists with the skills required to safely dive beneath ice layers and directly observe marine ecosystems that remain largely inaccessible through conventional methods. Training in controlled Arctic environments Training is currently taking place in Kilpisjärvi, northern Finland, where divers practise under-ice techniques in frozen lakes. These courses are provided by the Finnish Scientific Academy at the University of Helsinki’s Kilpisjärvi Biological Station. Such controlled environments offer safer conditions while still simulating the challenges of Arctic diving, including extreme cold, limited visibility, and restricted access points. While the training takes place inland, the skills are intended for use across Arctic marine environments, including coastal waters, fjords, and sea ice ecosystems throughout the region. Participants—often with backgrounds in fields such as marine biology and filmmaking—develop the skills needed to manage risks such as freezing equipment and low visibility. Exploring the hidden world beneath the ice Beneath the ice,...
