Environment & Climate Change

At one point in human history, water’s importance in war went beyond bearing convoys, hiding submarines, and slaking soldiers’ thirst. Water was often itself a weapon. In areas where it was scarce, armies took action to make it scarcer to force besieged enemy cities to capitulate, and in areas where it was abundant, combatants destroyed dams and watched the resulting floods carry their adversaries away. Today, however, most combatants recoil at the use of water as a weapon, and only the most depraved deploy it.

Since the end of World War II, nation-states in international conflict have made concerted efforts to restrain the weaponization of water. Distinct from realist and rationalist explanations, the historical record reveals the rise of an international normative inhibition—a “water taboo”—on using water as a weapon.

This essay makes three arguments. First, the US government will need to establish a coronavirus commission, similar to the 9/11 commission, to determine why, since April 2020, the United States has suffered more coronavirus fatalities than any other country in the world. Second, the COVID-19 pandemic represents a watershed for what will be a major national security theme this century: biological threats, both from naturally occurring pathogens and from synthesized biology. Third, intelligence about globalized challenges, such as pandemics, needs to be dramatically reconceptualized, stripping away outmoded levels of secrecy.

Joseph Nye writes that the world is increasingly obsessed with the ongoing power struggle between the United States and China. But the technology-driven shift of power away from states to transnational actors and global forces brings a new and unfamiliar complexity to global affairs.

Arctic Innovator Jenna Stark recommends closing the crisis-related collaboration gap in the polar region. Greater communication between emergency response specialists is needed both for the Arctic to weather the current coronavirus crisis and also to prepare for and mitigate future disasters, such as assuring food security for remote communities in the event of a wildlife disease outbreak.

Kaveri Iychettira and Afreen Siddiqi explain why computational modelling is a useful tool, especially when stakes are high and resources are constrained, and detail why developing countries should build capacity for it. 

Stephen Walt offers what he considers to be the top five silver linings from the COVID-19 pandemic.

Joel Clement appeared on CNN's Erin Burnett OutFront on April 23, 2020.  In this blog post for the Union of Concerned Scientists, he elaborates on what he wishes he had said during that interview.
