Transcript of Nuclear Winter

Nuclear Winter is a prediction that post nuclear war, our climate would become severely cold and lack sunlight due to soot and smoke sent into the Earth's atmosphere. The idea is that the fires caused by Nuclear explosions would send massive amounts of dark smoke limiting our sunlight and causing our temperatures to drop. A Nuclear War between the US and Russia would send temperatures below freezing in major argricultural areas. This would threaten our food supply. How does Nuclear Winter work? Mega cities with large amounts of fuel would add to potential fires.
This wouldn't necessarily harm everyone, only those close to targets.
However, the smoke that is sent into the troposphere would soak up sunlight which would heat the smoke.
This would send the hot smoke into the Stratosphere where it'd remain for years and would not wash out. Predictions First 1-3 Months, 10%-25% of soot would be washed away from precipitation. The rest would spread across the Earth.

If it were to happen in July..

the temperatures would drop 22 degrees C.
Rainfall would decrease by 75%
Visibility would drop by 90% in high smoke areas. It is also hypothesized that Nuclear Winter could cause our ozone to deplete and would lead to a dangerous UV radiation levels to seep into our world. To deal with the UV radiation
Our bodies would need to be covered head to toe.
We'd have to stay out of the sun as much as possible
Use high UV protection sunscreen
Protect our eyes, high amounts of UV can cause damage to our corneas. Eye damage can occur with little pain or discomfort. To handle the cold..
Have emergency heating supplies. Though electric, gas and oil may not be available.
Bundle up paying mind to extremities. Layers allow more movement than thicker clothes. Longstanding winter can most definately impact our ability to grow and harvest our food. The lack of sunlight and percipitation can keep us from having grown food.

Food would become vitally important so to survive you may want to have a significant amount of non perishable food and water. A minor nuclear war with each country using 50 Hiroshima bombs could produce climate change that we can't even fathom. Fat Man Climatic effects of the smoke from the burning cities and industrial areas would last beyond expected years. New models show with solar heating the smoke would continue to remain in the stratosphere Agriculture After World War II, super powers, the United States and the Soviet Union
were in a Cold War. The name stemming from the fact of that both were afraid of direct fighting because if they were in a "hot" war the nuclear weapons may destroy everything. In the 1980's, scientists began to work on the study of Nuclear Winter and it's repercussions. The realization of the effects of war ended the arms race between the US and the Soviet Union. Nuclear Radiation
The release of radiation happens
during a nuclear explosion. After a nuclear blast several types of radiation is released, Gamma, neutron and ionizing.

Initiallly, during the first minute of the blast, gamma and neutron radiation is expelled. This occurs only during neuclear fission within the fireball and only represents 3% of the total energy from the explosion. People would be killed instantly by letal doses of radiation and from the blast wave. Effects on Humans Effects of Nuclear Radiation on the human body depends on the amount of radiation that has been absorbed and the strength of the penetrating radiation. Depending on the amount,
Hair would fall out in clumps
Brain cells could deplete
Bloods lymphocyte cell count would drop leaving the body susceptable to infection.
Cause heart failure

Long term effects of the radiation would lead to malignant tumors, keloids, blood disorders and cataracts.
A minor war with each country using 50 hiroshima bombs would produce a climate change that we couldn't imagine. It would send the world into a 20 year nuclear winter.
