Its complex, for instance one scenario for Europe in the long time is actually a drastic cool down, incl. Something like a possible ice age due to global warming. The gulf stream (of Mexico) is what keeps parts of Europe warm. With melting ice, oceans are diluted which will cause the flow of gulf stream to slow down and not be able to reach Europe which will have "interesting" effects.
