Too subjective. Objectively climate has always been changing and will always be changing. Earth has seen much warmer climate and much colder climate and everything in between since formation. Your definition of issues don’t really make sense unless it’s subjective because objectively climate change is just is, not good not bad, just fact and consequence of complicated system. Even in the past many centuries, if you look at history, plenty of empires fell because of climate change(floods, droughts, etc). We are accelerating the change but it would still be changing even if we didn’t exist.
