Human Heredity Now and in the Future

| February 2019

The distinctive human characteristic of curiosity, once liberated from belief in supernatural causes of natural phenomena, has led with increasing speed to the brink of a world in which humanity will increasingly direct its own genetic endowment, raising the question of what we most value in being human and how to keep faith with it.

Stratospheric Aerosol Injection Tactics and Costs in the First 15 Years of Deployment

| 2018

We review the capabilities and costs of various lofting methods intended to deliver sulfates into the lower stratosphere. We lay out a future solar geoengineering deployment scenario of halving the increase in anthropogenic radiative forcing beginning 15 years hence, by deploying material to altitudes as high as ~20 km. After surveying an exhaustive list of potential deployment techniques, we settle upon an aircraft-based delivery system. Unlike the one prior comprehensive study on the topic (McClellan et al 2012 Environ. Res. Lett. 7 034019), we conclude that no existing aircraft design—even with extensive modifications—can reasonably fulfill this mission. However, we also conclude that developing a new, purpose-built high-altitude tanker with substantial payload capabilities would neither be technologically difficult nor prohibitively expensive. We calculate early-year costs of ~$1500 ton−1 of material deployed, resulting in average costs of ~$2.25 billion yr−1 over the first 15 years of deployment. We further calculate the number of flights at ~4000 in year one, linearly increasing by ~4000 yr−1. We conclude by arguing that, while cheap, such an aircraft-based program would unlikely be a secret, given the need for thousands of flights annually by airliner-sized aircraft operating from an international array of bases.

America Needs to Align Technology with a Public Purpose

| Nov. 25, 2018

The arc of innovative progress has reached an inflection point, writes Ash Carter in The Atlantic. "Recent technological change that has brought immeasurable improvements to billions around the globe now threatens to overwhelm us. Making this disruption positive for all is the chief challenge of our time. We ourselves—not only market forces—should bend the arc of change toward human good. To do so, we must reinvigorate an ethos of public purpose that has become dangerously decoupled from many of today’s leading tech endeavors."

China needs to manage its coal-dominated power system to curb carbon emissions, as well as to address local environmental priorities such as air pollution and water stress. In this article, the authors examine three province-level scenarios for 2030 that represent various electricity demand and low-carbon infrastructure development pathways.
