Large-scale chemical depletion of ozone due to anthropogenic emissions occurs over Antarctica as well as, to a lesser degree, the Arctic. Surface climate predictability in the Northern Hemisphere might be improved due to a previously proposed, albeit uncertain, link to springtime ozone depletion in the Arctic. Here we use observations and targeted chemistry-climate experiments from two models to isolate the surface impacts of ozone depletion from complex downward dynamical influences. We find that springtime stratospheric ozone depletion is consistently followed by surface temperature and precipitation anomalies with signs consistent with a positive Arctic Oscillation, namely, warm and dry conditions over southern Europe and Eurasia and moistening over northern Europe.

The United States has important entitlements to a wide swath of undersea territory in the Arctic and other regions that is rich in oil, natural gas, minerals, and sea life in an area known as the “extended continental shelf” (ECS). These unique maritime geographic features are defined and codified in international law and establishing rights will extend the United States’ subsea maritime reach well beyond the 200 nautical miles of the continental shelf to which all coastal states are entitled.

The reaction of narwhals to the loud noise from seismic air guns used in oil exploration involves a disruption of the normal physiological response to intense exercise as the animals try to escape the noise. The overall effect is a large increase in the energetic cost of diving while a paradoxically reduced heart rate alters the circulation of blood and oxygen.

The U.S. Department of Energy (DOE) today announced $14 million in funding for 22 projects aimed at improving climate change predictions. As extreme weather events and impacts of climate change continue to escalate, the research projects will advance fundamental scientific understanding of atmospheric processes, ranging from cloud formation to Arctic weather. Expanding the scientific understanding of extreme weather and climate patterns is key to tackling the climate crisis and meeting President Biden’s climate goals like slashing greenhouse-gas emissions. 

The events during the week of August 1st, 2022, will include Enhancing Arctic Science and Engineering Workshop along with Regional Development Tours and forums on the Arctic science to plan for the next 25 years of Arctic research. Participants will include scientists and engineers, Indigenous leaders, Arctic community members, policymakers, government organizations and businesses to celebrate past research success, take stock of current challenges and opportunities and plan for the next generation of collaboration and knowledge co-production that will keep Utqiagvik and Indigenous knowledge at the forefront of Arctic science and contribute to a safe and sustainable future for

the Arctic.

The Forum is organized in cooperation with Naalakkersuisut - The Government of Greenland. The Focus of the 2022 Greenland Forum will be on climate and prosperity; and, geopolitics and progress.

The Arctic Circle Assembly is an open democratic platform with participation from governments, organizations, corporations, universities, think tanks, environmental associations, indigenous communities, concerned citizens, and others. It is nonprofit and nonpartisan.

The Graduate Climate Conference (GCC) is an interdisciplinary climate conference run by graduate students, for graduate students. Over the last sixteen years, graduate students representing hundreds of academic institutions have come together to present research and share ideas on climate and climate change in an array of disciplines. Organizers welcome abstracts from diverse fields such as atmospheric sciences, biology, environmental management, forestry and fisheries sciences, oceanography, communication, public policy studies, urban planning, public health, and any other climate-related disciplines.

AGU Fall Meeting is the most influential event in the world dedicated to the advancement of Earth and space sciences. Every year, AGU Fall Meeting unites the Earth and space science community to share findings, connect like-minded scientists from around the world, and advance our profession and shared passion for the impact of science.

The International Symposium on Arctic Research (ISAR) has been held every two years since 2008 and aims to present and discuss scientific results with researchers on the Arctic from all-over the world, extracting and sharing issues to solve, and exploring the future of the Arctic. ISAR-7 will consist of General Sessions and Special Sessions. General Sessions will address the following topics: atmosphere; ocean and sea ice; rivers, lakes, permafrost, and snow cover; ice sheets, glaciers, and ice cores; terrestrial ecosystems; marine ecosystems; geospacer; laws, politics, and economy; language, culture, and health; and, engineering for sustainable development.
