A Chinese container vessel has set sail for Europe through the Arctic as part of a new weekly service on a route that cuts shipment times in half but that environmental groups warn could speed up the melting of polar ice.

Salt and sugar from the sea can rise as far as the free troposphere, thereby influencing both cloud formation and the Arctic climate. This is the finding of balloon measurements carried out by a team of researchers on Spitsbergen in autumn 2021 and spring 2022. With the Arctic becoming increasingly ice-free, more and more of these cloud-forming ingredients from seawater could enter the atmosphere and affect the radiation budget. The new findings therefore contribute to a better understanding of the complex interactions that lead to above-average warming in the Arctic, the researchers write in the journal Atmospheric Chemistry and Physics (ACP), an open-access journal of the European Geosciences Union (EGU).

The Alaska Defense Forum brings together military leaders, government officials, defense experts, industry representatives and community stakeholders to address the challenges and opportunities shaping Alaska’s role in national defense. Discussions will focus on Arctic security, strategic deterrence, emerging technologies, military readiness, infrastructure and investment, as well as the quality-of-life issues affecting service members, military families and defense communities. The forum is organized by the University of Alaska Fairbanks Geophysical Institute, the Fairbanks Economic Development Corporation and the Association of Defense Communities.

The Arctic Circle Assembly, organized by Arctic Circle, brings together government officials, business leaders, researchers, policy experts, community representatives, and international organizations to discuss Arctic affairs. Topics include geopolitics, security, international cooperation, economic development, energy and natural resources, shipping and infrastructure, scientific research, environmental change, and issues affecting Arctic communities.

Learn about the INSTAAR measurement program & tour the radiocarbon & stable isotope labs. This is part of Institute of Arctic and Alpine Research’s (INSTAAR) 75th Anniversary seminars.

Hosted by the American Geophysical Union, the 2026 AGU Annual Meeting covers research across the Earth and space sciences. Its Arctic-focused sessions will feature research on sea ice, permafrost, glaciers, oceans, atmospheric conditions, ecosystems, and freshwater systems, as well as the broader effects of Arctic change.

The Anchorage Security and Defense Dialogue (ASDD), hosted by the Ted Stevens Center for Arctic Security Studies, brings together military leaders, government officials, policymakers, researchers, industry representatives, and international partners to discuss security issues affecting the Arctic. The dialogue focuses on topics such as defense capabilities, homeland security, military readiness, technology, infrastructure, and cooperation among Arctic nations and allies. Through presentations, panel discussions, and working sessions, participants share information, discuss emerging challenges, and identify opportunities for coordination on Arctic security and defense priorities.

This event is by invitation only. This event is not open to the media. Due to the size constraints of the venue, early registration is encouraged. If you would like more information, please contact us at TSC-Engagements@groups.af.mil.

Hosted by the Sitka Sound Science Center, Sitka WhaleFest brings together scientists, educators, artists, conservation leaders, and community members to explore marine ecosystems, ocean conservation, and coastal culture through public presentations, wildlife experiences, educational programming, and community events focused on the North Pacific environment.

SAVE THE DATE! The Joint (AC)3 - MOSAiC Conference 2027 (JAMC27) offers a forum for open, multi-disciplinary scientific exchange on the overarching theme of "Drivers and Impacts of a Changing Arctic." The international polar research community is invited to present and discuss scientific results achieved over the past decade, including findings from (AC)3, MOSAiC, and other Arctic research activities. Conference goals are to synthesize recent advances, inform future research actions, and enhance societal uptake of research outcomes. Abstract submission will open in October 2026.

Hosted by the Arctic Council as part of the Kingdom of Denmark’s Chairship program, the Arctic Biodiversity Summit will bring together scientists, policymakers, Indigenous Peoples, youth leaders, and other Arctic stakeholders to strengthen collaboration on biodiversity conservation across the Arctic region. The summit is intended to serve as a strategic platform for advancing knowledge exchange, supporting sustainable development, and helping transform scientific and Indigenous knowledge into action-oriented policy and conservation efforts focused on protecting Arctic ecosystems and biodiversity for future generations.
