I am pretty sure the deployment of nuclear weapons on Hiroshima and Nagasaki did not affect global warming. There is no evidence to suggest that the deployment of nuclear weapons in the second World War affected global warming in any way.
Yes. They built Nuclear Weapons and showed the full effect. Surprisingly the Soviet Union won building the "Ivan" in the Arctic circle. But there was a little fighting and an attempt to actually launch nuclear missiles! This was in Cuba. Thats where the 'Cuban Missible Crisis' came from.

Probably not. If anything, nuclear explosions should have a cooling effect, because they send so much junk (soot, ash) into the atmosphere. It stays up there for a while, blocking light from the sun. This is the feared "nuclear winter" that would happen if a major nuclear exchange occurred. Volcanoes have a similar effect, but it takes quite a large eruption to have a noticeable effect.

Section.8 Freedom from Nuclear Weapons manufacturing nuclear and testing is prohibited in our country because the effect of nuclear in our environment is hazardous.
North Korea's development of nuclear weapons has served as a major deterrent for Western incursions into North Korea as well as increased fear from democratic neighbors like Japan and South Korea.
The use of a nuclear weapon on a country would be considered devestating, dependant on the payload and method of delivery of the nuclear device. It can destroy cities, and make the land infertile for many years afterwards please look towards Nagasaki and Hiroshima for more information. The "effect" of nuclear weapons on a country would depend on what your perspective is: there is something called MAD (Mutually Assured Destruction) of which the cold war is an example, where the development of a nuclear arsenal by one country (USSR) was profilgate in the development of a nuclear arsenal in another country (USA) this happened in many countries. Currently the body which is responsible for monitoring nuclear arsenals is called the IAEA (Internationl Atomic Energy Agency)
It is a negative effect. While it might be a neat invention to some, it is going to end up destructive and causing a lot of major issues.
Nuclear weapons serve as a deterrent. One country will be less likely to attack another that it knows has nuclear capability because of the destruction that could be wrought by nuclear weapons. This theory is called MAD or Mutually Assured Destruction, meaning that both sides would destroy each other so utterly by going to war that peace (even bitter cold peace) is the only viable option. Biological and Chemical weapons, which are also called weapons of mass destruction, do not have this deterrent effect.
One advantage of nuclear weapons is their deterrent effect, as they can discourage other states from attacking due to the devastating consequences. Additionally, possessing nuclear weapons can enhance a country's status in terms of security and influence on the global stage. Lastly, they can provide a form of strategic leverage in international negotiations and conflicts.
