Just read it in the news paper Irish Independed, that north Korea is helping and sharing their data about their own underground nuclear test with Iran.
Things are heating up fast, wonder when we see an open conflict with Iran and god knows what.
I asked my brother if a full nuclear exchange down there in the middle east (let's say 20+ small nukes) would have any impact on us (States Europe etc)..geology wise at all.
He is a Doctor in Geology:
He said, that apart from the usuall fallout nothing major will happen to us, the dust from all the explosions would of course go into the atmosphere and maybe lower the temp. world wide by one or two grades, but if you want to believe the clima warming some may even welcome this as something positive.
