Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

Joel Clement details the concerns surrounding the use of solar geoengineering to mask the effects of climate change and argues for using existing technology to quickly transition away from fossil fuels.

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

2021 Arctic Frontiers hosted a panel of young Arctic leaders alongside seasoned Arctic influencers who dove deeper into the opportunities and obstacles northern youth face now and in the future. Framed in the context of the UN's Sustainable Development Goals, speakers were invited to discuss the pressing issues that they stand to inherit such as climate change, societal pressure, migration of young people to the south, and the question of whether the Arctic is facing its own cultural revolution. This session sought to build bridges between generations, borders, and disciplines to find the best solutions for a resilient Arctic.

A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

Arctic Innovator Koshi Murakoshi proposes the creation of a "Global Arctic Innovation Hub." By bringing communities and scientists together, such a hub would prioritize local needs, but draw on global research.

The Internet of Things (IoT) refers to the increasing convergence of the physical and digital worlds and it affects us all. Hundreds of "things" are being connected to the Internet and each other, with more than fifty billion devices expected to be connected by 2030. Many IoT devices are manufactured abroad at low cost with little consideration for security. How can we secure these devices, especially those manufactured outside the United States?

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.
