Incidentally, the creationists that I've encountered diligently deny that our Earth's climate is being altered by people. This point of view and teaching is in absolutely no one's best interest. Here's hoping we can work together and preserve the Earth, for us - us humans.

There's nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.
