Well, wether it's colder, warmer, dryer, wetter, the same or different, at this point all possibilities are predicted by someone to be the consequence of human CO2 production at this point
Yes, but some more than others. A very zeitgeist example: warmer atmosphere stores more moisture and/or energy, thus causing more abrupt and violent changes of weather patterns - see the polar vortex breaking up and brining -40 degrees temperatures to unusual places in North America. This is something you can’t really negotiate about, it’s just applied thermodynamics.
