Current nuclear arsenals used in a war between the United States and Russia could inject 150 Tg of soot from fires ignited by nuclear explosions into the upper troposphere and lower stratosphere. We simulate the climate response using the Community Earth System Model‐Whole Atmosphere Community Climate Model version 4 (WACCM4), run at 2° horizontal resolution with 66 layers from the surface to 140 km, with full stratospheric chemistry and with aerosols from the Community Aerosol and Radiation… Expand
Nuclear Niño response observed in simulations of nuclear war scenarios
The climate impacts of smoke from fires ignited by nuclear war would include global cooling and crop failure. Facing increased reliance on ocean-based food sources, it is critical to understand theExpand
Extreme Ozone Loss Following Nuclear War Results in Enhanced Surface Ultraviolet Radiation
It has been understood since the early days of nuclear weapons testing that nuclear detonations can initiate large-scale fires in urban and rural settings (Glasstone & Dolan, 1977; OTA, 1979; Lewis,Expand
The Influence of Stratospheric Soot and Sulfate Aerosols on the Northern Hemisphere Wintertime Atmospheric Circulation
Considerable effort has been devoted to characterizing the forced climate response of explosive volcanic eruptions. In particular, the significance of the “winter warming” of continental areas in theExpand
The Potential Impact of Nuclear Conflict on Ocean Acidification
We demonstrate that the global cooling resulting from a range of nuclear conflict scenarios would temporarily increase the pH in the surface ocean by up to 0.06 units over a 5-year period, brieflyExpand
Rapidly expanding nuclear arsenals in Pakistan and India portend regional and global catastrophe
TLDR
Severe global climate change and a record death toll could result from nuclear war between India and Pakistan in the next decade, with larger regional impacts. Expand
Upper Atmosphere Smoke Injection from Large Areal Fires
Large fires can inject smoke into the upper troposphere and lower stratosphere. Detailed fire simulations allow for assessment of how local weather interacts with these fires and affects smokeExpand
A regional nuclear conflict would compromise global food security
TLDR
This study shows that a regional conflict using <1% of the worldwide nuclear arsenal could have adverse consequences for global food security unmatched in modern history. Expand
The Impact of a Regional Nuclear Conflict between India and Pakistan: Two Views
ABSTRACT The severity of climatic effects of a regional nuclear conflict between India and Pakistan, involving the use of a hundred Hiroshima-scale nuclear weapons, is contested between two groups;Expand
Marine wild-capture fisheries after nuclear war
TLDR
It is shown that agricultural losses could not be offset by the world’s fisheries, especially given widespread overfishing, and effective prewar management that rebuilds fish biomass could ensure a short-term catch buffer large enough to replace ∼43 ± 35% of today's global animal protein production.

How an India-Pakistan nuclear war could start—and have global consequences
ABSTRACT This article describes how an India-Pakistan nuclear war might come to pass, and what the local and global effects of such a war might be. The direct effects of this nuclear exchange wouldExpand
