The authors argue that more determined efforts to globalize renewable energy transmission can confer significantly higher economic and environmental benefits from renewables on billions of people. This can be done by exploiting spatial differences between electricity loads and net renewable generation across time zones (temporal arbitrage) and latitude (seasonal arbitrage). Using very long distance, ultra-high voltage (UHV) transmission infrastructure, temporal and spatial arbitrage can move low-cost clean electricity from areas with excess capacity to high demand zones in other countries and even continents.

The Belt and Road Initiative (BRI) is an important cooperative framework that increasingly affects the global economy, trade, and emission patterns. However, most existing studies pay insufficient attention to consumption-based emissions, embodied emissions, and non-CO2 greenhouse gases (GHGs). This study constructs a GHG emissions database to study the trends and variations in production-based, consumption-based, and embodied emissions associated with BRI countries

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

This paper examines a recent, rapid, and ongoing transition of India's lighting market to light emitting diode (LED) technology, from a negligible market share to LEDs becoming the dominant lighting products within five years, despite the country's otherwise limited visibility in the global solid-state lighting industry.

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 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.

In an event co-hosted by the Project on Europe and the Transatlantic Relationship’s (PETR) and the Asia Center, Cathryn Clüver Ashbrook, Executive Director of the Future of Diplomacy Project and the Project on Europe and the Transatlantic Relationship, moderated a panel discussion on China’s technological rise and its impact on the US-EU relationship. The panel featured Joel Brenner, Senior Research Fellow at the Center for International Studies; Danil Kerimi, Head of Technology Industries Sector, Digital Economy and Global Technology Policy, the World Economic Forum; Meicen Sun, PhD Candidate in the Department of Political Sciences at MIT; and Daniel Weitzner, Founding Director of the Internet Policy Research Initiative. 

Bruce Schneier  explains that there is no escaping the technology of inevitable surveillance. Consumers have little choice but to rely on the companies that build their computers and write their software, whether in  smartphones,  5G wireless infrastructure, or subway cars.  China is more likely to try to get data from the U.S. communications infrastructure like the United States does rather than try to produce a subway car outfitted with surveillance apparatus.

Although Trump did not outline his legal basis for imposing the tariffs, several analysts anticipated that he was seeking to use the authorities granted him under the International Emergency Economic Powers Act—the legal basis that presidents rely on to impose financial and economic sanctions against WMD proliferators, terrorist organizations, narco-traffickers, and human rights abusers. Mixing trade and immigration policy under the guise of a national security threat, however, may end up deflating Trump’s “maximum pressure” sanctions campaigns against Iran and North Korea.

Understanding deterrence in cyberspace is often difficult, because  minds remain captured by an image of deterrence shaped by the Cold War: a threat of massive retaliation to a nuclear attack by nuclear means. A better analogy is crime: governments can only imperfectly prevent it.
