Earth's Ozone Part 1

A nuclear war involving 100 Hiroshima-size bombs would open a massive hole in the earth's ozone layer, exposing life to dangerous levels of the sun's rays, a new study shows.
Smoke caused by the atomic explosions would trap heat in the stratosphere and lead to the deterioration of more than 20 percent of ozone globally, according to a study published today in Proceedings of the National Academy of Sciences. The findings suggest a more severe ``nuclear winter'' resulting from a massive nuclear war than was predicted in the 1980s.
``There would be an ozone hole everywhere outside the tropics,'' said lead author Michael Mills of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder. ``The human health consequences would certainly be large increases in skin cancer and cataracts. The impacts could be greater on ecosystems.''
The study supports research published last year that said a nuclear conflict between Pakistan and India involving 100 Hiroshima-size bombs would cause enough smoke to cool the earth's temperature to the dramatically lower temperatures, shortening growing seasons and rain levels in some areas.
Although the risk of global nuclear war has diminished since the 1980s, the proliferation of nuclear weapons has produced greater risks of a regional nuclear conflict.
