I live in a region with an annual temperature difference of 70 degrees Celsius in not goodanouth year . if they tell me that the summer will be hotter by 5 degrees Celsius and the winter will be 10 degrees colder I will not even feel most likely. still if you spit to the ground only ice will reach the ground. And whether or not you deny heating has nothing to do with it. Of course maybe mankind is warming the earth enough, or maybe the Little Ice Age is ending. If you care about that, ok. I don't.
