generally more extreme weather. more wind, more droughts, more storms, etc. we already have this but it will only get worse. depending how far it goes, it could theoretically reach apocalyptic extremes, but supposedly enough action has been taken already that we've probably avoided that. now it's a question of whether things just get a bit worse or a lot worse.
(warming oceans can cause the thermohaline (ocean circulation) to stop working, since it release on large temperature differences between warm and cold parts of the planet. the last time this happened it resulted in (or at least happened at the same time as) a global extinction event. I don't know how close this is to happening.)
it is possible that some places have milder weather and have less to worry about than others. I hope your implication is not "something has to affect me personally to matter, even if it affects the other 99% of the planet".
The truth basks in scrutiny.
