In reality, if "Global Warming" does exist, then it would actually happen like that - at least in Europe. Except for the whole thing about the guy going to save his son.
And it disappearing after a few days.
Basically, the gulf stream carries water heated by the sun from South-Central America across the Atlantic Ocean, and heats up North-West Europe, by a large amount. Just to give you a little comparison, in Cananda along the same latitude lines they have polar bears and the sea freezes over in the winter.
This "conveyor belt", as it's called, relies on the water being reused, like in a conveyor belt, funnily enough. When it leaves SC-America it's warm, so it rises to the surface. After it's done heating NW Europe, it sinks again, and travels under the hot water back to SC-America.
The problem arises when you see that the fresh water coming in from the melting Arctic ice caps does not sink like the salt water because it is less dense. So the conveyor stops flowing, and Europe gets rather cold.
The only doubts some people have is to whether "Global Warming" is actually caused by CO2
emissions. My ranting chemistry teacher never used to think so, he said that there was one
graph of data which supported it, and it had been manipulated in the campaigner's favour - something to do with CO2
absorbtion per litre.
Anyway, it doesn't matter if what he says is right - there are still lots of doubts, and lots of people saying it does exist.
As for the quakes, it's probably just Earth having it's menstrual cycle, it does it sometimes, it'll go back to normal in couple of years.
