Environment & Climate Change

Joseph S. Nye argues that history shows that globalization is largely driven by technological changes that reduce the importance of distance, and that will not change.

The economist and HKS professor is passionate about solving what may be humanity's most important and perplexing problem: How to untangle fossil fuels from the global economy.

In its push for greener energy, Washington is giving biofuels a boost. But just how green are they? Daniel Schrag, Co-Director of the Science, Technology, and Public Policy Program, argued the case for biofuels, opposite Carlisle Ford Runge, who argued against them.

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?

In late 2017, Mexico made headlines as Italian company Enel bid what was then a world-record low price for renewable energy in the country’s third such energy auction. This development was possible due to the historical and sweeping energy reforms passed with broad support in Mexico in 2013. Then-President Enrique Peña Nieto had succeeded where previous Mexican presidents had failed, reversing decades of resource nationalism and overhauling the energy sector through constitutional reforms that gave the private sector a larger role and advantaged renewable energy in Mexico’s economy. The 2017 auction seemed to indicate Mexico’s bright future not only as a conventional oil producer, but also as a clean energy power.

Russian military action in Ukraine could trigger an energy crisis even more serious than the one already hitting Europe. As has been pointed out, should the West hit Russia with severe new sanctions, President Vladimir Putin could cut off natural gas exports, leaving the continent shivering through midwinter. Yet there is another potential weapon of Russia’s that’s been less discussed and might be very effective: An ability to disrupt global oil markets, which would directly hit U.S. consumers.

Joseph Nye  discusses the following: Why the United States must work with China on global issues such as climate change, pandemics, and other transnational concerns, despite rivalry between the two countries; the "three-dimensional chess game" between the U.S. and China, with military, economic, and ecological boards; the importance of soft power; and differences from the U.S. relationship with the Soviet Union.

Stephen Walt enumerates the challenges the U.S. president should prepare for in 2021.

Joseph Nye analyzes why the Cold War metaphor in relation to  the U.S. and China, although convenient, is lazy and potentially dangerous. It obscures and misleads us by underestimating the real challenge we face — and offering ineffective strategies.

Stephen Walt explains why the Biden administration should not expect its closest European allies by its side as it gears up for a long-term struggle in China.
