A nuclear war that cooled Earth could worsen the impact of ocean acidification on corals, clams, oysters and other marine life with shells or skeletons, according to the first study of its kind.
“We found that the ocean’s chemistry would change, with global cooling dissolving atmospheric carbon into the upper ocean and exacerbating the primary threat of ocean acidification,” said co-author Alan Robock, a Distinguished Professor in the Department of Environmental Sciences in the School of Environmental and Biological Sciences at Rutgers University–New Brunswick.
The study is published in the journal Geophysical Research Letters.
Scientists looked at how climate changes stemming from nuclear war would affect the oceans. They used a global climate model in which the climate reacted to soot (black carbon) in smoke that would be injected into the upper atmosphere from fires ignited by nuclear weapons. They considered a range of hypothetical nuclear wars, including a relatively small one between India and Pakistan and a large one between the United States and Russia.
