February Newsletter: Nuclear War Risk Analysis

Dear friends, In order to most effectively reduce the risk of global catastrophe, it is often essential to have a quantitative understanding of the risk. It is particularly essential when we are faced with decisions that involve tradeoffs between different risks and decisions that require prioritizing among multiple risks. For this reason, GCRI has long been at the forefront of the risk and decision analysis of global catastrophic risk. This month, we announce a new paper, “Reflections on the Risk Analysis of Nuclear War”. This paper summarizes the …

May Newsletter: Molecular Nanotechnology

Dear friends,

It has been a productive month for GCRI, with new papers by several of our affiliates. Here, I would like to highlight one by Steven Umbrello and myself, on the topic of molecular nanotechnology, also known as atomically precise manufacturing (APM).

At present, APM exists only in a crude form, such as the work recognized by the 2016 Nobel Prize in Chemistry. However, it may be able to revolutionize manufacturing, making it inexpensive and easy to produce a wide range of goods, resulting in what …

April Newsletter: Nuclear War Impacts

Dear friends,

This month we are announcing a new paper, “A Model for the Impacts of Nuclear War”, co-authored by Tony Barrett and myself. The paper presents a detailed and comprehensive accounting of the many ways that nuclear war can harm human beings and human society. It is a counterpart to the paper we announced last month, “A Model for the Probability of Nuclear War”.

The model has five main branches corresponding to the five main types of impacts of nuclear weapon detonations: thermal radiation, blast, ionizing …

A Model For The Impacts Of Nuclear War

View the paper “A Model For The Impacts Of Nuclear War”

The total impact of nuclear war is a major factor in many important policy questions, but it has gotten little scholarly attention. This paper presents a model for calculating the total impacts of nuclear war. The model includes physical, infrastructural, and social impacts as they affect human lives. The model has five main branches corresponding to the five main types of effects of nuclear weapon detonations: thermal radiation, blast, ionizing radiation, electromagnetic pulse, and human …

March Newsletter: Nuclear War Probability

Dear friends,

This month we are announcing a new paper, “A Model for the Probability of Nuclear War”, co-authored by Robert de Neufville, Tony Barrett, and myself. The paper presents the most detailed accounting of the probability of nuclear war yet available.

The core of the paper is a model covering 14 scenarios for how nuclear war could occur. In 6 scenarios, a state intentionally starts nuclear war. In the other 8, a state mistakenly believes it is under nuclear attack by another state and starts nuclear …

A Model For The Probability Of Nuclear War

View the paper “A Model For The Probability Of Nuclear War”

The probability of nuclear war is a major factor in many important policy questions, but it has gotten little scholarly attention. This paper presents a model for calculating the total probability of nuclear war. The model is based on 14 interrelated scenarios for how nuclear war can break out, covering perhaps the entire range of nuclear war scenarios. Scenarios vary based on factors including whether a state intends to make a first strike attack, whether …

Bulletin of Atomic Scientists: Trump and Global Catastrophic Risk

GCRI Executive Director Seth Baum has a new article in Bulletin of the Atomic Scientists on what Donald Trump’s election means for global catastrophic risk, which has been covered in Quartz and Elite Daily. Baum writes that the fact that Trump will have the authority to launch nuclear weapons should particularly concern us, given his tendency to behave erratically, Trump’s election also has implications for the prospect of conflict with Russia and China, the stability of the global world order, the survival of democracy in the US, and our …

By Matthijs Maas

In the early hours of September 9, North Korea carried out its fifth nuclear test, its biggest ever at an estimated 10 kilotons. The test, which was first detected as a magnitude 5.3-earthquake, was condemned by the UN Security Council, as well as leaders from across the world. In a statement, North Korea said it had tested a “nuclear warhead… standardized to be able to be mounted on strategic ballistic rockets”. …

President Obama became the first sitting US president to visit Hiroshima, just a little more than one month after Secretary of State John Kerry became the highest ranking US official to visit the city where the US detonated a nuclear weapon at the end of World War II. Obama laid a wreath at the Hiroshima Peace Memorial, but did not apologize for the use of nuclear weapons against Japan. …
