Some people say why worry about global warming

Personally I live in Michigan and some of my uninformed friends will say things like “Global Warming is good at least our winters won’t be as bad” and “why should I care if the polar ice cap melts, I’ve never seen the north pool and don’t ever plan on too.”

Many of my friends would be surprised to know that during the last ice age the world was only 6 degrees cooler on average then they are now. During the last ice age Michigan had a two mile deep glacier over it.

If 6 degrees cooler then average can cause a 2 mile think glacier too form over Michigan what would 6 degrees of warming do. Kind of scary when you think about it.
