see, you have to wonder if they picked the wrong stream here on purpose.
should melting waters fuck with the jet stream? well, they're in completely different layers of the earth's structure, and thereby part of completely different systems. you'd have to come up with some way as to how.
but, should melting waters fuck with the gulf stream? well, yeah. fucking right they should. that would piss the brits off, i bet.
you'd have to point out that the oceans in the gulf are warming though, so it's a question of where a new equilibrium falls, as the oceans shift around and make sense of the new normal, whenever that itself arrives.
but, none of that should really have much of an affect on the jet stream. not by the way i understand how things work, anyways.
