Nuclear Weapons: the most urgent green issue - Ecocentric - TIME.com: "Environmentalists: Wake up! There is a greater and more urgent threat to the climate than even global warming: the threat posed by nuclear weapons.
Why are nuclear bombs an environmental problem? We have long known that a large-scale nuclear war would lead to a sudden change in climate—called a nuclear winter—that could threaten all life on earth. But in the past decade, climate scientists have used advanced climate modeling to show that even a small exchange of nuclear weapons—between 50-100 Hiroshima-sized bombs, which India and Pakistan already have their in arsenal—would produce enough soot and smoke to block out sunlight, cool the planet, and produce climate change unprecedented in recorded human history."
