Robert Stavins closely examines the advantages and disadvantages of two distinct pricing instruments for reducing carbon emissions—carbon taxes and cap-and-trade. Both policy instruments are in common use today in many countries although not in the United States. Stavins looks at the practical challenges, financial implications, and political feasibility of both approaches, concluding that while they are equivalent in many ways, they can perform quite differently along other dimensions, making an apples-to-apples comparison quite difficult.

For an assessment of what was done, and left undone, at the recent United Nations’ Conference of the Parties on climate change, the Gazette spoke with Rob Stavins, the Harvard Kennedy School’s A.J. Meyer Professor of Energy and Economic Development and head of the Harvard Project on Climate Agreements, who attended his first COP in 2007 in Bali. 

There is an urgent need to incorporate the latest science on carbon emissions from permafrost thaw and northern wildfires into international consideration of how much more aggressively societal emissions must be reduced to address the global climate crisis.

Professors Robert N. Stavins and David Victor explore how the coronavirus pandemic has tested the ability of many governments to respond to crises. Climate change could require a similar approach.

Former U.S. lead climate negotiator Sue Biniaz shares her thoughts on the postponement of COP26 in this interview by Professor Robert Stavins. Stavins and Biniaz explore ways to reimagine future United Nations climate negotiations, unresolved concerns from COP25, and how the United States might approach rejoining the Paris Agreement.

In his new book, Do Morals Matter? Presidents and Foreign Policy from FDR to Trump, Joseph S. Nye developed a scorecard to determine how U.S. presidents since 1945 factored questions of ethics and morality into their foreign policy. In an interview, Henry Farrell asked him a few questions to get to the heart of his findings.

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

Over the past decade, the Arctic has warmed by 0.75°C, far outpacing the global average, while Antarctic temperatures have remained comparatively stable. As Earth approaches 2°C warming, the Arctic and Antarctic may reach 4°C and 2°C mean annual warming, and 7°C and 3°C winter warming, respectively. Expected consequences of increased Arctic warming include ongoing loss of land and sea ice, threats to wildlife and traditional human livelihoods, increased methane emissions, and extreme weather at lower latitudes.

In this edition of "The Interview," Fair Observer talks to Professor John Holdren, former science adviser to President Barack Obama and director of the White House Office of Science and Technology Policy from 2009 to 2017 about the impacts of global warming on the United States and the government's strategies to combat climate change.
