How do you explain seasonal cold weather if the climate is warming

They call it global warming. Its where the earth heats up and instead of having snow in some areas they'll have rain or they don't have any moisture what so ever. There are some times where it snows but it usually snows on one day and the next day is warm and the snow is melted. I live in Colorado and right now it is winter but its warm outside that is the example of global warming.
