One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new joint study from the University of Gothenburg and the German Alfred Wegener Institute. As a result, the North Atlantic could be flooded with freshwater, which would weaken the global ocean circulation.

For the first time, researchers have collected detailed measurements of water vapor high above the surface of the Greenland ice sheet. Their research, aided by a custom-designed drone, could help scientists improve ice loss calculations in rapidly warming polar regions. 

Launched just seven months ago, ESA’s Arctic Weather Satellite has been proving how the New Space approach can accelerate the development of missions capable of delivering detailed temperature and humidity profiles for short-term weather forecasts.

The Federal Maritime Commission (Commission) has exercised its statutory authority to initiate a nonadjudicatory investigation into transit constraints at international maritime chokepoints, particularly concerning the effects of the laws, regulations or practices of foreign governments, and the practices of owners or operators of foreign-flag vessels, on shipping conditions in these chokepoints. Including, (C.) Northern Sea Passage:

The Northern Sea Passage is emerging as a critical maritime chokepoint as new shipping routes open, a development that could reshape global trade patterns. As the region's waters become ice-free for longer periods, the Northern Sea Passage offers a shortcut between Europe and Asia, reducing travel time and fuel consumption. However, this has sparked competition over governance, with Russia seeking control over the shortest maritime route between Europe and Asia, and imposing fees, while other nations push for international access. The Northern Sea Passage's strategic importance is further amplified by increased military activity from Russia and China, including new bases and icebreakers, reflecting its growing value for nuclear deterrence and missile defense. As a result, both Russia and NATO forces are ramping up their military presence, increasing the potential for tensions and conflicts over access to the region's trade routes and resources.

This notice requests information from the public to assist MARAD in determining which shipyards in the United States have the capacity, capability, and readiness to construct ships capable of operating in ice conditions and determining what factors would be necessary to further develop icebreaker ships in the United States. The objectives of the request are to increase the capacity of the United States to design, produce, and maintain polar icebreakers through trilateral collaboration while supporting each country's shipbuilding industrial base.

Comments must be received on or before April 9, 2025.

Securing the North and South poles is critical due to their strategic significance and natural resources. The United States, along with our partners and allies are poised to maintain a strong military presence to ensure the continuance of navigational freedoms and safeguards against potential near peer adversaries seeking to control these critical areas. Protecting these remote frontiers is key to preserving environmental stability and geopolitical balance.

The City of Nome Investment Summit aims to bring together the public and private sectors to highlight investment opportunities in Nome. Nome is on the front lines of Arctic science diplomacy and U.S. power projection in the Arctic. The Port of Nome is of national significance as the nation’s first deep draft port in the U.S. Arctic and serves as a refueling and resupply support facility.

Arctic Encounter, North America’s leading conference on Arctic policy and business, annually gathers over 1,000 participants from more than two dozen countries. As a nonprofit NGO, Arctic Encounter convenes and hosts dialogues and policy debates. Hosted in downtown Anchorage, Alaska, the event offers participants a unique blend of arts, culture, and critical discussions, contributing to a deeper understanding of Arctic challenges and opportunities.

Every year, AGU’s Annual Meeting convenes >25,000 attendees from 100+ countries to share scientific findings and make connections. Researchers, scientists, educators, students, policymakers, exhibitors, journalists and communicators attend AGU’s Annual Meeting to better understand our planet and environment, and our role in preserving its future. It is a results-oriented gathering rooted in celebrating and advancing positive individual and collective outcomes.
