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.

 The Gazette spoke with John Holdren, Teresa and John Heinz Professor of Environmental Policy at the Harvard Kennedy School and professor of environmental science and policy in the Department of Earth and Planetary Sciences, about what the incoming Biden-Harris administration reinstalling science as a foundation for government policy means.

Senator Richard G. Lugar: An Appreciation

| Apr. 30, 2019

Sen. Richard Lugar—with his legislative partner, Sen. Sam Nunn—imagined the unimaginable. He championed a program to provide assistance to military forces in the former Soviet republics holding tens of thousands of nuclear, chemical, and biological weapons aimed at the United States and our allies, shortly after America’s existential enemy, the Soviet Union, expired. All told, the Nunn-Lugar cooperative threat reduction program provided more than $14 billion to, among other things, deactivate 13,300 nuclear warheads, eliminate 1,473 intercontinental ballistic missiles, and destroy almost 40,000 metric tons of chemical agents. The US departments of Defense and Energy also worked with Russia to improve security at 148 sites still holding nuclear weapons or weapons-grade material from Murmansk to Kamchatka.

The Future of the Nuclear Order

| April 2019

Foreign policy pundits have bemoaned the unraveling of the post-World War II international order in recent years, describing threats to the multilateralism and liberalism enshrined in postwar institutions. An often overlooked component of that structure is the global nuclear order, which, like other parts of the postwar system, was created for magnanimous and selfish aims: reducing the dangers of nuclear weapons for all and serving the interests of the world’s most powerful states.

Dim Hope for Disarmament and Approaching Risk of Build-Up

| March 2019

Further nuclear reduction under the current regimes seems unlikely. The US argues that Russia has violated the INF Treaty by developing and deploying a land-based cruise missile. Russia also makes the accusation that the Aegis Ashore missile defense system in Europe, capable of launching cruise missiles, has violated the INF. Furthermore, President Trump has repeatedly expressed his unwillingness to extend the New START Treaty for five more years after it expires in February 2021. The US-Russia bilateral disarmament process seems to have terminated. There have been some signs of nuclear build-up. The new US Nuclear Posture Review emphasizes the role of nuclear weapons while de-emphasizing strategic stability, reduces the threshold for nuclear use and calls for developing new low-yield SLBM and sea-launched cruise missiles. America’s nuclear policy might stimulate Russia and China to build new nuclear capabilities. North Korea’s advances in nuclear and long-range missile programs justify Washington’s investment in homeland missile defense, which in turn undermines China and Russia’s nuclear retaliatory capability and might result in a defense-offense arms race.
