Environment & Climate Change

Stephen M. Walt describes a "gnawing fear that we are living through a series of disruptions that are overwhelming our collective ability to respond." What does this mean for public confidence in the entire political system, and is there any cause for optimism?

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

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.

Estimating the long-term effect of the current pandemic is not an exact prediction of the future, but an exercise in weighing probabilities and adjusting current policies. When envisioning the international order in 2030,  joseph Nye details five scenarios that stand out.

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.

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.

Today’s economic crisis leaves us with an unsettling and perplexing regret. Why weren’t financial portfolios already adjusted for risks that stem from health events such as pandemics? After all, financial portfolios are adjusted for liquidity risks, market risks, credit risks, and even operational and political risks.

How do presidents incorporate morality into decisions involving the national interest? Moral considerations explain why Truman, who authorized the use of nuclear weapons in Japan during World War II, later refused General MacArthur's request to use them in China during the Korean War. What is contextual intelligence, and how does it explain why Bush 41 is ranked first in foreign policy, but Bush 43 is found wanting? Is it possible for a president to lie in the service of the public interest? In this episode, Professor Joseph S. Nye considers these questions as he explores the role of morality in presidential decision-making from FDR to Trump.

Joseph Nye writes that some decoupling of interdependence is likely, particularly in areas related to technology that directly affect national security. But will Washington and Beijing go too far?
