Plastic pollution in the Arctic marine system is sparsely quantified, and few enforceable policies are in place to ameliorate the issue. In this paper, Dewey and Mackie estimate the flux of plastic through rivers, sea ice, and ocean, and quantify marine plastic pollution from Arctic shipping and fishing. They also examine how a suite of proposed policy interventions would quantitatively change those concentrations.

Chinese strategists increasingly believe that U.S. nonnuclear strategic capabilities threaten China’s nuclear forces. Although there is limited evidence of a shift in its nuclear strategy, China is changing its strategic posture to ensure its second-strike capability, including by relying on advanced conventional weapons (e.g., counterspace capabilities, cyber weapons, and electronic warfare) that can target U.S. missile defense. The dynamics of a nuclear-conventional entangled security dilemma may weaken arms race stability.

Divestment is a prominent strategy championed by activists to induce positive social change. For example, the current fossil fuel divestment movement includes over 1,500 institutions that control $40 trillion in assets. A primary pathway through which divestment is theorized to be effective is by influencing public beliefs and policy preferences, thus pressuring policymakers to take action. However, prior research only tests this argument via qualitative case studies. The authors assess the impact of exposure to information about fossil fuel divestment on public opinion through the use of national survey experiments in three major greenhouse gas emitters: the U.S., India, and South Africa.

This paper explores the unique conditions that made the Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean possible and examines how success was achieved by the interrelationships of science, policy, legal structures, politics, stakeholder collaboration, and diplomacy.

In the wake of the global financial crisis of 2008, China began to move away from the market-based approach that had shaped its economic policies for three decades, and toward something that might be termed "party-state capitalism," which involves a high degree of CC control over strategic sectors of the economy. This has led to significant changes in the U.S.-Chinese economic relationship, as both sides have made efforts to secure supply chains, screen inward and outward capital flows, diminish the power of global firms, and reorganize alliances to protect against economic coercion.

An analysis of Taiwan’s military value concludes that its reunification with China would improve Chinese submarine warfare and ocean surveillance capabilities, tipping the military balance in China’s favor. These findings have important implications for U.S. operational planning, policy, and grand strategy.

Of all the intractable issues that could spark a hot war between the United States and China, Taiwan is at the very top of the list. And the potential geopolitical consequences of such a war would be profound. Taiwan-"an unsinkable aircraft carrier and submarine tender," as U.S. Army General Douglas MacArthur once described it--has important, often underappreciated military value as a gateway to the Philippine Sea, a vital theater for defending Japan, the Philippines, and South Korea from possible Chinese coercion or attack.

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

Could a conventional war between China and the United States escalate to the nuclear level? An assessment of three mechanisms of China-U.S. inadvertent escalation—use-it-or-lose-it, unauthorized/accidental, and damage limitation—concludes that the risk of China-U.S. inadvertent nuclear escalation is extremely low.

During war, states trade two types of products with their enemies. To maximize revenues, states continue to trade products that are essential to the domestic economy or that their adversary takes a long time to convert into militarily capabilities.
