From a point of view, sure, everything has to do with religion. But the bible doesn't prove that global warming doesn't exist. Based on the huge CO2 build up in our atmosphere from man-made industries and whatnot, there is no believing, or not believing in global warming; It's fact and it's going on right now. It's just a matter of how fast or slow we're going through it. And based on what we're doing to actually "prevent" it rather than support the cause, there's bound to be a climate change which will play a huge part in extinction of animals.
Note that "The Greenhouse Theory" is a theory which is what you're saying global warming is. In that case, you're going by a theory to prove that another "theory," as you said global warming was, is wrong. Am I not right?
