Despite its below-freezing temperatures, the Arctic is warming twice as fast as the rest of the planet. As Arctic sea ice melts, fewer bright surfaces are available to reflect sunlight back into space. When fractures open in the ice cover, the water underneath gets exposed. Dark, ice-free water absorbs the sun's energy, heating the ocean and driving further melting—a vicious cycle. This warming in turn melts glacial ice, contributing to rising sea levels.

The Sea Ice Prediction Network–Phase 2 (SIPN2) announces the call for contributions for the 2022 Sea Ice Outlook (SIO) June report. The SIO provides an open process for those interested in Arctic sea-ice to share ideas. Four monthly reports during the sea-ice retreat season will include a variety of contributions—from advanced numerical models to qualitative perspectives from citizen scientists—as well as brief related discussions.

In a proof-of-concept study, we recently used equilibrium sampling with silicone films to noninvasively derive the thermodynamic limit to a canine’s gastrointestinal biomagnification capability (BMFlim) by determining the ratio of the products of the volume (V) and fugacity capacity (Z) of food and feces. In that earlier study, low contaminant levels prevented the determination of contaminant fugacities (f) in food and feces. For zoo-housed polar bears, fed on a lipid-rich diet of fish and seal oil, we were now able to measure the increase in f of nine native polychlorinated biphenyls (PCBs) upon digestion, providing incontestable proof of the process of gastrointestinal biomagnification.

The National Oceanic and Atmospheric Administration and NASA plans to launch NOAA’s third polar-orbiting environmental satellite to orbit aboard a United Launch Alliance Atlas V rocket no later than Nov. 1. NASA said Joint Polar Satellite System-2 is slated to lift off from the Vanderberg Space Force Base in California to capture global environmental data to boost the accuracy of weather monitoring and forecasting.

This event is hosted by The Arctic Institute (TAI). This event will include topics on: cultural security, economic security, energy security, environmental security, food security, health security, military security, and political security.

The US CLIVAR Observing, Modeling, and Understanding the Circulation of the Arctic Ocean and Sub-Arctic Seas Workshop will explore changes in Arctic Ocean and sub-Arctic seas circulation related to global change and the observing system required to track those changes in the future. The observing system design effort will be cognizant of the practical, geopolitical, and operational constraints of Arctic Ocean observing, but will incorporate modern objective experimental design and data assimilation using numerical models as fundamental guiding principles. Its work will contribute to evaluations of model simulations and observational analyses to assess opportunities for model improvements.

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.

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.
