Here is an awesome new perspective on global climate disaster. From Jeff Goldstein in huffpost:

Every Geologic Day, Earth will write in her diary the comings and goings for that day. Here's the next important point:

Every one of the 27,394 pages in Earth's diary -- each Geologic Day -- is 365,000 years long enough time for 14,600 human generations.

How come? Easy: 10 billion years divided by 27,394.

Amazing synchronicity!  Read his whole article, inspired by his young son asking him a simple question:

About a month ago, I was driving my son to school on a sunny day. So he started asking me lots of questions about the Sun. "How old is it? How long will it live? What will happen to Earth when the Sun dies?" I started explaining, and in the middle of it he shut me down with this one: "Daddy, how long is a billion years?" It's why I wrote this post.
