Actually, it shows there is a "normal" in the time frame of our ability to live on this planet. It shows that the Earth has different extremes and is capable of becoming uninhabitable for humans. I don't know about you, but I'm not selfish enough to only be concerned about my own life, but I do hope this planet is here and capable of supporting Human life long after I'm gone.
I'd hope that as humans and having intelligence much higher than those monkeys hanging around in trees that we would do what ever possible to keep this planet habitable for a long long time.
