Environment & Climate Change

To date, most of the climate policy attention has been focused on the need to reduce the greenhouse gases that are causing climate change and, as a corollary, to accelerate the U.S. economy’s transition from fossil fuels to clean energy. Yet climate change also is straining our nation’s emergency response capabilities as traditional climate-infused disasters such as hurricanes and floods become more frequent and destructive. At the same time, the emergency response community faces new challenges as slower-to-develop climate impacts like drought, heat, and wildfire increasingly are hitting an acute tipping points and becoming life- and livelihood-threatening disasters.

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.

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.
