Climate change

First of all, I'm not stating anywhere that climate change is or isn't happening, and I'm not here to write that the following is something of major importance to us, albeit I thought that this topic might be of interest to some. So here goes: Does climate change affect the type of snow that falls in a cold region at a specific (given) temperature? For instance, if it's 32 degrees, we might have snowflakes of diameter 1 inch with very intricate, fractal-like branching arms form and that's what might snow on the ground. However, with climate change, at 32 degrees, at the same altitude, would the snowflakes take on a different shape and size? Would they now be 2 inches instead of 1, and have less complex branching arms, more like simple hexagons?! That's my question for today. I'd like to take these photos at specified temperatures using my high resolution camera, and compare them throughout the years, for signs, or evidence, of any "deformation" of ice crystals as might be a factor of the (manmade or natural) changing climate. Increased certain amount of gas, such as CO2, might actually cause ice crystals to "morph" into different shapes, although that would have to be a truly dramatic increase (or decrease) in gas concentrations, or in other words, if the balance of gasses in Earth's atmosphere changes, then that might change the atmospheric pressure, perhaps causing different kinds of snowflakes to form as opposed to how they formed in the past!
