Climate change is a much better term. More CO2 means the atmosphere traps more energy. Truth is we don't know exactly what that will do. Some areas may become warmer, some cooler, some drier or wetter, etc. Its also possible that entropy goes up and weather becomes more extreme and less predictable. As far as just warming goes polar warming is probably the most concerning as it could melt massive amounts of ice and lead to damaging sea level rise.
