The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The Overwhelming Case for No First Use

| Jan. 13, 2020

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.

Julius Weitzdörfer: Managing the Impact of Nuclear Disasters

| Fall/Winter 2019-2020

Julius Weitzdörfer’s earliest childhood memories are the major global events of 1986—the Space Shuttle Challenger explosion and the Chernobyl disaster. Looking back, he realizes that these events must have contributed to shaping his later research interests in managing technological risks.

How to Ensure Iran Never Resumes Reprocessing

| Dec. 13, 2017

Though the negotiation leading to the JCPOA took place over a significant stretch of time—indeed, it was built on the foundation of talks that began in 2003—it’s important to remember that the deal contains critical concessions regarding Iran’s production of plutonium, which the United States had been seeking from Tehran since the 1970s, when the two countries were allies.

Iran Stockpiling Uranium Far Above Current Needs

| January 10, 2017

In a televised speech on January 1, Iranian President Hassan Rouhani said that Tehran had imported 200 metric tons of yellowcake uranium and would import another 120 tons at an unspecified future date. The imports are permitted by the nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), but nonetheless significantly exceed Iran’s needs for natural (that is, unenriched) uranium over the next 15 years. Iran’s import of such high levels of uranium suggests it may be stockpiling uranium to reach nuclear breakout before the deal’s initial limitations expire in 2031.

The JCPOA permits Iran to buy natural uranium to “replenish” its stocks as it sells enriched uranium on the international market. To date, Iran has had difficulties locating a buyer for its enriched uranium stocks – unsurprising, given the current excess of commercially available enriched uranium. This, however, has not stopped Iran from buying and stockpiling more yellowcake.

The Nuclear Security Summit and the IAEA: Advocating Much and Avoiding Specifics

| Apr. 08, 2016

The 2016 Nuclear Security Summit (NSS) in Washington D.C. on 1 April issued a seven-page Action Plan in Support of the International Atomic Energy Agency (IAEA). It contains steps that the summit participants commit themselves to taking and those they “advocate” the Agency “pursue”. In endorsing this plan, 2016 Summit participants focused more detailed attention on the IAEA than those who participated in the previous four nuclear security summits.

IAEA Releases Guidelines on Nuclear Material Control and Accounting

| June 09, 2015

More than a decade after its nuclear security recommendations first recognized the threat insiders pose to nuclear facilities, the International Atomic Energy Agency (IAEA) has finally released its guide on nuclear material control and accounting for nuclear security.  (This has been in the works for years.) Many people wrongly think that any material under international safeguards has accounting and control good enough for security purposes as well, but there are important differences.

On the Road to Nowhere? New Proposals on the Middle East WMD-Free Zone May Backfire

| May 11, 2015

"One of the dramas playing out this month in New York at the 2015 Review Conference for parties to the Treaty on the Non-proliferation of Nuclear Weapons (NPT) concerns the future of discussions on establishing the weapons of mass destruction free zone in the Middle East..."
