|December 23, 1983
Summary
Nuclear war could cause severe global climate change, including extreme cold and darkness, threatening survivors. Even a 100-megaton conflict may trigger significant atmospheric and climatic consequences worldwide.
Area of Science:
- Atmospheric Science
- Climatology
- Nuclear Winter Studies
Background:
- Volcanic eruption models provide a basis for assessing nuclear war impacts.
- Previous studies highlight potential atmospheric disturbances from large-scale events.
Purpose of the Study:
- To investigate the global atmospheric and climatic consequences of nuclear war.
- To determine the potential impact of nuclear detonations on solar radiation, temperature, and radioactivity distribution.
Main Methods:
- Utilized models developed for volcanic eruption studies.
- Simulated nuclear exchanges of varying yields (e.g., 100 megatons to 5000 megatons).
- Analyzed dust and smoke injection, solar radiation attenuation, temperature changes, and radioactive fallout.
Main Results:
- Significant solar radiation reduction and subfreezing temperatures are probable due to dust and smoke.
- Even relatively small conflicts (100 megatons) can cause major optical and climatic effects.
- Radioactive fallout and enhanced UV radiation pose long-term threats to survivors.
Conclusions:
- Nuclear war presents a serious threat to global climate and human survival.
- The threshold for severe climatic consequences may be lower than previously thought.
- Atmospheric transport of particles and radioactivity can affect both hemispheres.

02:50Nuclear Fission
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large number of different...
02:36Nuclear Power
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.

03:20Nuclear Transmutation
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...
03:18Nuclear Stability
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

02:45Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
