A blasting of mushroom cloud, an explosion of hot air and a flash of light: All this is enough to leave people horrified. However, a new study discloses that there is much more to a nuclear war that one cannot even think about. In fact, novelists and filmmakers have been tackling this crucial subject for decades and many are clear in their approach and some just confronting it.

Presently, a team of environmental and U.S. atmospheric scientists have glanced at what all the debris, ash and dust in the air can result in. Through the advanced climate predicting software, they ran computer models on a fight between India and Pakistan.

As expected, the outcome was bad. Even for this limited nuclear war, it is estimated a one-to-one degree drop in global temperature and a 9% cut in worldwide rainfall. Now, this equals to worldwide crop failures.

According to a separate study conducted by the scientists, the projected death toll increases to 2 billion lives. Shockingly, this is a result of little nuclear war, not a big one like the fight of China and Russia.

Further, the report states, "A limited, regional nuclear war between India and Pakistan in which each side detonates 50 15 Kt weapons could produce about five Megatons of black carbon". This would automatically result in 'nuclear winter', which will last 25 years, double than that of past estimates.

In overpopulated areas, 20-50% loss is predicted in the density of the ozone layer. This would cause widespread damage to the natural ecosystem, agriculture and not to forget, it will lead to human skin cancer. Now, it can be rightly said that this is too much for a limited nuclear war.
