The Bible has been mis-labeled as a strictly "religious" book.  It is no such thing.  It is full of history, practical observations, common sense sayings, and much more.  It was hijacked by "religion".  When most of it was originally written, it wasn't even viewed as religious material, more like tribal history, with laws, rules, regulations mixed in.  It was more of a tribal survival manual, than anything else.  Yes, it involves a belief structure, a God.  Science hadn't been invented yet.  You let your children believe in Santa Clause?  If you're not an accredited scientist, with years of experience and peer review, who specializes in one of the many disciplines surrounding the science of Global Warming, then Global Warming can be only a belief for you.  You simply "believe" what the scientists say, but you cannot verify it independently.  If you won any of your college debates, it may not have been because you were so smart, it could have been because your opponents were so dumb.
