@Mamapolo2016 Agreed. The "nuclear winter" that follows an all-out nuclear war will cause agricultural collapse almost everywhere. Ocean temperatures will also drop, killing algae and disrupting marine ecosystems.
Even though their nuclear arsenals have been cut in size and average yield since the end of the Cold War, a nuclear exchange between the United States and Russia would still likely initiate a much more severe nuclear winter, with much of the northern hemisphere facing below-freezing temperatures even during the summer. A global nuclear war that injected 150 Tg of soot into the stratosphere could make temperatures drop by 8 degrees Celsius—3 degrees lower than Ice Age values.
