Global Warming - a new thought

So I have always been concerned about the environment. I try to recycle. I don't litter. My wife and I drive 1 car to work. I have learned about global warming since elementary school but it has never been a big deal to me until today. I came home from work played with Paul III and after we put him to bed read Newsweek. Newsweek was focused on the environment and had a section on Global Warming. As I was reading the article I realized that global warming may have a small effect on my life but what effect might it have on Paul's life or on his children's lives? Now that was a powerful thought.
