I support your intent of countering the “intelligent” design “theorists” and their stealth efforts to bring in Creationism into the classroom (and kick out science). However, what’s this business of pirates vs. global surface temperature. Sure, you make a point that there’s a difference between correlation and causation. Perhaps you’re trying to point out that the true cause of GW may not be man-made green-house gas emissions. Well, the scientists have studied this problem and have come to the conclusion that it is. Please don’t give with one hand and take with the other. You support the scientists in Darwinian evolution and on the other hand don’t in GW science.
I suggest you remove your references to pirates and global surface temperature (your curve does look compelling though).
[A response: No deal, Alan. I tend to agree with the Global Warming hypothesis, and I certainly think it makes sense to err in that direction whether or not you agree with it – I’m all for conservation and green technologies. But, there is an almost religious type of dogma surrounding the Global Warming issue that makes me uncomfortable. Global warming is probably happening, but that is a world apart from saying it is Truth that must be supported. I’m against dogma and a priori reasoning, not any specific beliefs. -bobby]
