The Arctic Oscillation (AO) has been observed to undergo distinct decadal structural fluctuations that significantly influence regional weather and climate. Understanding the drivers and mechanisms behind the AO’s spatial nonstationarity is critical for improving climate predictions related to the AO. We present evidence that the Atlantic Multidecadal Oscillation (AMO) plays a pivotal role in modulating AO’s Pacific center in recent decades. The poleward amplified cooling associated with negative AMO enhances the north-south temperature gradient and results the strengthened westerly winds and stratospheric polar vortex (SPV) responses, which reflects more planetary waves from the North Pacific to the North Atlantic.

The warming climate in polar regions may significantly disrupt ocean circulation patterns, a new study indicates. Scientists discovered that in the distant past, growing inflows of freshwater from melting Arctic sea-ice into the Nordic Seas likely significantly affected ocean circulation, sending temperatures plummeting across northern Europe.

The Arctic is warming at three to four times the global average. However, new research suggests the slowing of a key ocean current could reduce projected Arctic warming by up to 2 degrees Celsius by the end of the century.

At the Court of Appeal of the N.W.T. on Tuesday, lawyers for the N.W.T. government and Colville Lake disagreed on treaty interpretations in a pivotal moment for caribou management rights. It’s the latest in a longstanding process between the territory and Colville Lake over caribou management plans.

As the planet heats up, polar bears are being exposed to more parasites, bacteria and viruses, likely through their food, according to a new study published Wednesday in the journal PLOS ONE. Since these massive marine mammals are at the top of the food chain, the findings suggest that other Arctic animals are also at greater risk of contracting pathogens as the climate warms.

Western scientists studying the Arctic are increasingly lost in the hunt for data, the result of the cutoff in relations with Russia. Crucial climate science has been stymied as Russia, which makes up over half the Arctic, continues its war in Ukraine. Data flowing between Western and Russian scientists has slowed to a trickle with Western-imposed sanctions and other restrictions, interrupting work on a host of projects.

Energy policy analysts predict an expanded role for hydrogen (H2) in the future energy mix, with H2 projected to account for as much as 30% of the energy supply in some sectors and demand increasing more than five-fold by 2050. To achieve climate objectives, these projections involve methane derived H2 coupled with carbon sequestration (blue H2), and H2 generated by electrolysis of water using renewable sources of electricity (green H2). Reaching these goals will require an unprecedented investment in new technology and infrastructure. I will discuss what we know and don’t know about the global resource potential for natural hydrogen, how we can apply existing resource exploration strategies, and what new knowledge and technologies are needed to improve our understanding of this previously overlooked potential energy resource.

The inaugural Anchorage Security and Defense Conference (ASDC) will convene defense and security practitioners to discuss challenges and opportunities in the circumpolar Arctic and neighboring regions that have international security implications. By providing a forum for dialogue, the ASDC will develop potential solutions and actionable recommendations for practitioners. This year’s theme is drawn from the U.S. National Security Strategy which identifies the 2020s as a “decisive decade.” The inaugural ASDC is an opportunity to examine the geopolitical shifts of the 2020s and their nexus in the Arctic, the North Atlantic, and the North Pacific.

ArcticNet's 5th International Arctic Change Conference (AC2024) brings together researchers from the natural, health, and social sciences to meet the challenges and opportunities of a rapidly changing Arctic region. This conference will push the boundaries of our collective understanding of the Arctic and strengthen our ability to address the issues of today and tomorrow. The Arctic Change Conference brings together a broad range of research in and about the Arctic and northern regions of Canada and the world. The AC2024 advances our collective understanding with an inclusive view of the North spanning from Inuit Nunangat, across the Canadian territories and provinces, circumpolar Arctic regions, and beyond.

Each year, AGU’s annual meeting, the largest gathering of Earth and space scientists, convenes 25,000+ attendees from 100+ countries to share research and connect with friends and colleagues. Scientists, educators, policymakers, journalists and communicators attend AGU24 to better understand our planet and environment, opening pathways to discovery, opening greater awareness to address climate change, opening greater collaborations to lead to solutions and opening the fields and professions of science to a whole new age of justice equity, diversity, inclusion and belonging.

The challenges of today go beyond deadlines decided by governments, territorial claims of oceans and lands, or borders drawn on a map. Addressing global issues requires collaborative efforts and swift decision-making. Dismantling the barriers between science, business, and policy is necessary to deepen communication and enhance our understanding of the pan-Arctic ecosystem. Modern challenges, such as the impacts of climate change, fostering sustainable development, and navigating political tensions, are deeply interconnected. Whilst the financial, societal, and environmental costs of the green transition will not be fairly distributed worldwide, the Arctic is part of the solution.

The Alaska Marine Science Symposium (AMSS), Alaska’s premier marine research conference, has been bringing together scientists, educators, resource managers, students, and interested public for over twenty years to discuss the latest marine research being conducted in Alaskan waters. Over 700 people attend this conference held annually during the month of January. Each day of the conference highlights important Alaskan marine ecosystems: Gulf of Alaska (Tuesday), Arctic (Wednesday), and the Bering Sea & Aleutian Islands (Thursday). Research topics discussed range from ocean physics, fishes and invertebrates, seabirds, marine mammals, to local traditional knowledge. Since its inception, NPRB has been a proud sponsor and one of the leading organizers of AMSS.

Arctic360’s Annual Event brings together Northern and Indigenous governments, institutions, and corporations; global finance; state leaders; mining, innovation, and other industry leaders; and Arctic experts from Canada and around the circumpolar North to advance the conversation and foster action for building a sustainable, peaceful, and prosperous Arctic region.

In lead up to its 35th anniversary in 2025, the International Arctic Science Committee (IASC) is coordinating a multi-year planning process for the Fourth International Conference on Arctic Research Planning (ICARP IV) that will engage Arctic researchers, policymakers, residents, and stakeholders from around the world to collegially discuss the state of Arctic science, the place the Arctic occupies in global affairs and systems, to consider the most urgent knowledge gaps and research priorities that lie before us and to explore avenues to address these research needs. This event is hosted by a consortium of US institutions, including the University of Colorado Boulder, University of Northern Iowa, University of Alaska Fairbanks, and Alaska Pacific University. ICARP I, II, and III focused the attention of the world’s researchers toward the value of strategic international coordination in accelerating progress in addressing critical challenges. ICARP IV will build upon this concept by striving to achieve consensus and build collaborations among the leading scientific, academic, environmental, Indigenous and political organizations currently concerned with Arctic issues.
