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?

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.

The geopolitical and geo-economic forces wrought by the coronavirus pandemic, as examined previously in this series, are likely to slow the transition to a more sustainable global energy mix. Fortunately, the pandemic has also resulted in governments gaining vastly greater influence over whether this shift stalls or accelerates.

For most people, there was nothing to celebrate when the International Monetary Fund downgraded its outlook for global economic growth in June, anticipating a contraction of 4.9% for 2020. Yet for others, such as the small but persistent group of economists and others known as the “degrowth movement,” the Covid-induced economic slowdown has a silver lining.

The search for silver linings to the coronavirus pandemic has come up woefully short. But one hopeful — and much talked of — prospect is that the disruption will accelerate the global shift to a more sustainable energy future.

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.
