this is complete bs by the way it's not nearly as simple as the Gulf Stream being the only factor keeping northern europe more temperate, it probably won't collapse in "a matter of years" so much as a matter of decades or centuries, and the cooling effect that has will likely be offset by other factors such as an ice-free Arctic no longer acting to limit heating of the northern oceans

Omgv yes please i want to freeze to death instead of sweat

i don't think anyone has a good idea what will actually happen from that, it seems very silly to suggest it'd be worse than climes on similar latitude without a gulf stream. Russian east & Canada are cold but they aren't unlivable---and they're becoming warmer like everywhere
