By Not Acting on Climate, Congress Endangers U.S. National Security

| July 21, 2022

Last week, U.S. Sen. Joe Manchin seemingly dashed Democrats’ hopes for congressional action to slow climate change. Sen. Bernie Sanders accused Manchin of “sabotag[ing] the president’s agenda”; Rep. John Yarmuth, when asked about the consequences of Congress not acting on climate change, said, “We’re all going to die”; and climate activists, as well as some Democrats in Congress, wondered if Manchin should be removed as chair of the Senate Energy and Natural Resources Committee.

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.

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.

What Can the Secret Service Teach Us About Nuclear Security?

| January 12, 2015

"One of the more notable storylines throughout 2014 was the continued failures of the U.S. Secret Service. There were three striking high profile lapses in the Secret Service’s ability to protect President Obama: one where a man jumped over the White House fence, running through the front door of the White House and throughout its main floor; another where an armed man with an arrest record was able to ride on the same elevator as the President; and another where a man posing as a Member of Congress was able  to sneak into a secured area where the President was speaking. Towards the end of the year, problems within the Secret Service became a hotly debated political football, resulting in the resignation of the Service’s director..."

Fall/Winter 2014-15 Belfer Center Newsletter

| Fall/Winter 2014-2015

The Fall/Winter 2014/15 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This edition highlights discussions at the Belfer Center about Iran and its nuclear program. Former U.S. National Security Advisor and Center Senior Fellow Thomas Donilon and former Israeli National Security Advisor Yaakov Amidror added their voices to Center debate on this issue during a Harvard Kennedy School forum on a possible deal to prevent development of nuclear weapons in Iran.

In "Stopping ISIL," a number of Belfer Center security experts weigh in on what must be done in the next year to stop the spread and brutality of the Islamic State (ISIL). Graham Allison, Nicholas Burns, Chuck Freilich, Nawaf Obaid, Ariane Tabatabai, Payam Mohseni, David Petraeus, Gary Samore, and Barak Mendelsohn suggest solutions to this strategic challenge.
