If the planet is getting warmer. Why do we have Blizzards?

I think the reason for us having these blizzards is because the ice caps are melting. Since there melting theirs not a way for us not to have a blizzard. I feel that since were damaging our own planet no one sees the damage until the damage has already taken place. I say this to explain that we sit here not recycling, smoking, cutting down trees, etc,etc. And no one is seeing the damage being done to the atmosphere, so the weather is showing us that we need to take an effect now. So we can at least slow down the process off or summers becoming hotter then excepted, Making it hit a new record.
