  2. IPPNW Co-President Ira Helfand

  3. Climate Consequences of Regional Nuclear War Scenario 100 Hiroshima-sized bombs detonated over cities in India and Pakistan International Physicians for the Prevention of Nuclear War

  4. Climate Consequences of Regional Nuclear War • 20 million fatalities • Extensive radioactive fallout • Global climate effects lasting a decade or more International Physicians for the Prevention of Nuclear War

  5. Climate Consequences of Regional Nuclear War • Nuclear explosions ignite fires that burn whole cities • Soot lofted high into the atmosphere absorbs incoming sunlight • Dramatic decrease in amount of light reaching the surface • Large, rapid drops in surface temperature International Physicians for the Prevention of Nuclear War

  9. Tambora Volcano • Erupted April 1815 • -0.7 degrees C temperature drop • Dramatic shortening of growing season International Physicians for the Prevention of Nuclear War

  10. Nuclear War: The Impact on Agriculture • Sudden cooling, decreased sunlight, less rainfall shortens growing seasons; reduces crop yields • Stratospheric ozone depletiondamages crops sensitive to UV-B • Disruption of petroleum supplies affects use of farm machinery and fertilizer and pesticide production • Radioactive and toxic contaminationtakes farmland out of production • Collapse of distribution system International Physicians for the Prevention of Nuclear War

  17. Chronic Malnutrition Today • 1,800-2,200 calories minimum daily requirement • 1 billion people at or below this level of daily intake • 20% acute malnutrition in Kenya, Ethiopia, Somalia • 1/3 children <5 malnourished in sub-Saharan Africa International Physicians for the Prevention of Nuclear War

  18. Great Bengal Famine of 1943 • Food production declined only 5% • Actually 13% higher than 1941 when there was no famine • 3 million people died International Physicians for the Prevention of Nuclear War

  19. Global South + China: 2 billion victims of starvation from nuclear famine? International Physicians for the Prevention of Nuclear War

  20. Epidemic Disease • Plague • Cholera • Malaria • Typhus International Physicians for the Prevention of Nuclear War

  21. …further use of nuclear weapons? International Physicians for the Prevention of Nuclear War

  22. Surface Air Temperatures 2 years after 150 million tons of smoke enters stratosphere Decrease in Surface Air Temperatures 2 years after full-scale nuclear war

  23. Climate effects of a full-scale nuclear conflict
