Rise or Recede? How Climate Disasters Affect Armed Conflict Intensity

    Author:

| Spring 2023

Climate disasters shape the trajectory of internal conflicts in states highly vulnerable to changes in conflict dynamics. Conflict after a climate disaster escalates when the disaster induces shifts in relative power that enable one side to increase its military efforts. But when one actor is weakened by the disaster and the other lacks the capability to exploit that weakness, conflict intensity declines.

Enabling a Significant Nuclear Role in China’s Decarbonization

| Dec. 02, 2021

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

American Nuclear Diplomacy

| August 4, 2016

In this report, American Nuclear Diplomacy: Forging a New Consensus to Fight Climate Change and Weapons Proliferation, Former Deputy Secretary of Energy and Belfer Center Senior Fellow Daniel Poneman writes that we face two existential threats: nuclear annihilation and catastrophic climate change. Each, he says, stems from human origins. Both must be fought aggressively.

"Multiple studies confirm the grim truth that, even if all nations fulfill their Paris Climate Agreement emissions pledges, the world will still far overshoot the 2°C warming limit scientists say we must not exceed to prevent devastating climate impacts. Carbon-free nuclear energy can help close the gap. But can we expand its environmental benefits without increasing the risks of nuclear terror?"

Poneman outlines a diplomatic strategy and tough-minded, bipartisan policies to get us there.

Energy Secretary Ernest Moniz: Statesman of Science and Diplomacy

| Summer 2016

Verification is a crucial part of all arms control agreements, from the Intermediate-Range Nuclear Forces Treaty in the 1980s to the recent Iran nuclear deal, U.S. Energy Secretary Ernest Moniz explained during a recent appearance at Harvard. And it is on verification where scientists can be decisive.
