"The theory is the warming (whatever the cause) is melting the ice and that fresh melted water is entering the gulf stream, the gulf stream keeps half the world from freezing to death, if the gulf stream stops as they predict then we move into a mini ice age."
Yeah, just like the Hollywood flop. The oceans have risen over 100 metres since the last ice age and probably at rates far greater than today. There was a vast melting of ice. So why didn't you get a heap of interruptions to the thermohaline circulation then?
