Nuclear winter revisited with a modern climate model and current nuclear arsenals: Still catastrophic consequences

Nuclear winter revisited with a modern climate model and current nuclear arsenals: Still catastrophic consequences

[1] Twenty years ago, the results of climate model simulations of the response to smoke and dust from a massive nuclear exchange between the superpowers could be summarized as ‘‘nuclear winter,’’ with rapid temperature, precipitation, and insolation drops at the surface that would threaten global agriculture for at least a year. The global nuclear arsenal has fallen by a factor of three since t...

Climate and smoke: an appraisal of nuclear winter.

The latest understanding of nuclear winter is reviewed. Considerable progress has been made in quantifying the production and injection of soot by large-scale fires, the regional and global atmospheric dispersion of the soot, and the resulting physical, environmental, and climatic perturbations. New information has been obtained from laboratory studies, field experiments, and numerical modeli...

Strengthening the Nonproliferation Regime: The Challenge of Regional Nuclear Arsenals

Recent Fukushima nuclear detonation, Chernobyl nuclear fallout, three mile island nuclear accident and atomic bomb explosion – rethinking the effects of nuclear radiations over human health

Background: The earlier Atomic Bomb explosion in Hiroshima and Nagasaki, and three worth mentioning nuclear accidents - detonation at Fukushima Daiichi nuclear plant, Chernobyl nuclear fallout and an accident at Three Mile Island nuclear power plant have made us more worried about the secure exploitation of nuclear energy. The central focus of this paper is to review radiation-mediated health e...

Modern Theory of Nuclear Forces

Nuclear forces can be systematically derived using effective chiral Lagrangians consistent with the symmetries of QCD. I review the status of the calculations for two-and three-nucleon forces and their applications in few-nucleon systems. I also address issues like the quark mass dependence of the nuclear forces and resonance saturation for four-nucleon operators.
