Judah Cohen (Atmospheric and Environmental Research, Inc.) will present this topic as part of the NOAA Science Seminar Series. The presentation will include an analysis of a dynamical link between rapid Arctic change and extreme winter weather across large regions of the Northern Hemisphere. Given the link between SCE and SPV variability, SCE could be utilized in subseasonal to seasonal prediction in the winter months.

Dene leaders are gathered this week on Chief Drygeese Territory for the Dene National Assembly, discussing the work they are doing for their communities, their challenges, and important areas for advocacy like housing, education, wellness and treatment programs and child welfare. “It’s a space and time for us to reflect with each other about a lot of things that are really close to our heart, looking at how we can be able to do things together going forward,” said Dene National Chief Gerald Antoine.

Plans are afoot to send the first Indian team of researchers to the Canadian High Arctic Research Station (CHARS) located in Canada’s Cambridge Bay, Nunavut, to study the impact of climate change on glacial melt. The studies and findings are planned to be subsequently utilized to better understand the impact of climate change on glacial melting in the Himalayas.

Migratory animals experience very different environmental conditions at different times of the year, i.e., at the breeding grounds, during migration, and in winter. The long-tailed duck Clangula hyemalis breeds in the Arctic regions of the northern hemisphere and migrates to temperate climate zones, where it winters in marine environments. The breeding success of the long-tailed duck is affected by the abundances of predators and their main prey species, lemmings Lemmus sibiricus and Dicrostonyx torquatus, whose population fluctuation is subject to climate change. In the winter quarters, long-tailed ducks mainly eat the blue mussel Mytilus edulis. We examined how North-west Siberian lemming dynamics, assumed as a proxy for predation pressure, affect long-tailed duck breeding success and how nutrient availability in the Baltic Sea influences long-tailed duck population size via mussel biomass and quality.

Scientists investigating the growth of arctic vegetation have found that seed dispersal and fire will slow its land expansion in the long term, despite more favorable conditions from a warming planet. Previous estimates predicted that arctic shrubs—stubby, dense bushes that cover much of the tundra region—would eventually conquer about 39% of the non-shrub area in the Arctic.

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.
