The Open Philanthropy Project awarded a grant of $2,982,206 over three years to Professor Alan Robock via Rutgers University to support a series of modeling studies on the climatological and subsequent ecological and social effects of large nuclear conflicts, conducted by Professor Robock and Professor Owen Brian Toon of the University of Colorado Boulder. This grant falls within Open Philanthropy's work on global catastrophic risks, and will primarily cover salaries and tuition for graduate students and postdocs.
The study will aim to investigate what nuclear war scenarios of different sizes are plausible; how much material would be ignited and how much soot would be produced in those scenarios; how that soot would be transported and modified in the atmosphere; how the global climate would respond to that soot, if at all; how agriculture and the ocean would respond to those global climate changes; and how that would affect the global economy and food security. Open Philanthropy hopes this research will increase understanding about the probability and characteristics of disturbances to the global climate system (and subsequent effects on society and ecosystems) that could result from a range of potential nuclear conflicts.
